code uses, such as bitmaps, layout definitions, user interface strings, animation instructions, and more.</p> <p>Always externalize app resources such as images and strings from your code, so that you can maintain them independently. Also, provide alternative resources for specific device configurations by grouping them in specially named resource directories. At runtime, Android uses the appropriate resource based on the current configuration. For example, you might want to provide a different UI layout depending on the screen size or different strings depending on the language setting.</p> <p>Once you externalize your app resources, you can access them using resource IDs that are generated in your project's <code translate="no" dir="ltr">R</code> class. This document shows you how to group the resources in your Android project. It also shows you how to provide alternative resources for specific device configurations and then access them from your app code or other XML files.</p> <h2 id="ResourceTypes" data-text="Group resource types" tabindex="-1">Group resource types</h2> <p>Place each type of resource in a specific subdirectory of your project's <code translate="no" dir="ltr">res/</code> directory.

It causes a compiler error.</p> <p>For more information about the individual types of resources, see the <a href="/guide/topics/resources/available-resources">Resource types overview</a>.</p> <p>The resources that you save in the subdirectories defined in table 1 are your default resources. That is, these resources define the default design and content for your app. However, different types of Android-powered devices might call for different types of resources.</p> <p>For example, you can provide different layout resources for devices that have larger than normal screens to take advantage of the extra screen space. You can also provide different string resources that translate the text in your user interface based on the device's language setting. To provide these different resources for different device configurations, you need to provide alternative resources in addition to your default resources.</p> <h2 id="AlternativeResources" data-text="Provide alternative resources" tabindex="-1">Provide alternative resources</h2> <p>Most apps provide alternative resources to support specific device configurations. For instance, include alternative drawable resources for different screen densities and alternative string resources for different languages. At runtime, Android detects the current device configuration and loads the appropriate resources for your app.</p> <img class="android-image-dark-theme-background" src="/static/images/resources/resource_devices_diagram2.png" alt> <p class="img-caption"> <strong>Figure 1.</strong> Two devices using different layout resources based on screen size.</p> <p>To specify configuration-specific alternatives for a set of resources, do the following:</p> <ol> <li>Create a new directory in <code translate="no" dir="ltr">res/</code> named in the form <code translate="no" dir="ltr"><em><resources_name></em>-<em><qualifier></em></code>. <ul> <li><em><code translate="no" dir="ltr"><resources_name></code></em> is the directory name of the corresponding default resources (defined in table 1).</li> <li><em><code translate="no" dir="ltr"><qualifier></code></em> is a name that specifies an individual configuration for which these resources are to be used (defined in table 2).</li> </ul> <p>You can append more than one <em><code translate="no" dir="ltr"><qualifier></code></em>. Separate each one with a dash.</p> <p class="caution"><strong>Caution:</strong> When appending multiple qualifiers, you must place them in the same order in which they are listed in table 2. If the qualifiers are ordered incorrectly, the resources are ignored.</p> </li> <li>Save the appropriate alternative resources in this new directory. The resource files must be named exactly the same as the default resource files.</li> </ol> <p>For example, here are some default and alternative resources:</p> <pre class="none" translate="no" dir="ltr"> res/ drawable/ icon.png background.png drawable-hdpi/ icon.png background.png </pre> <p>The <code translate="no" dir="ltr">hdpi</code> qualifier indicates that the resources in that directory are for devices with a high-density screen. The images in these drawable directories are sized for specific screen densities, but the filenames are exactly the same. This way, the resource ID that you use to reference the <code translate="no" dir="ltr">icon.png</code> or <code translate="no" dir="ltr">background.png</code> image is always the same. Android selects the version of each resource that best matches the current device by comparing the device configuration information with the qualifiers in the resource directory name.</p> <p class="caution"><strong>Caution:</strong> When defining an alternative resource, make sure you also define the resource in a default configuration. Otherwise, your app might encounter runtime exceptions when the device changes a configuration. For example, if you add a string to only <code translate="no" dir="ltr">values-en</code> and not <code translate="no" dir="ltr">values</code>, your app might encounter a <code translate="no" dir="ltr">Resource Not Found</code> exception when the user changes the default system language.</p> <p>Table 2 lists the valid configuration qualifiers in order of precedence. You can add multiple qualifiers to one directory name by separating each qualifier with a dash. If you use multiple qualifiers for a resource directory, you must add them to the directory name in the order they are listed in the table.</p> <p class="table-caption" id="table2"><strong>Table 2.</strong> Configuration qualifier names.</p> <table> <tr> <th>Configuration</th> <th>Qualifier values</th> <th>Description</th> </tr> <tr id="MccQualifier"> <td>MCC and MNC</td> <td>Examples:<br/> <code translate="no" dir="ltr">mcc310</code><br/> <code translate="no" dir="ltr"><nobr>mcc310-mnc004</nobr></code><br/> <code translate="no" dir="ltr">mcc208-mnc00</code> </td> <td> <p>The mobile country code (MCC), optionally followed by the mobile network code (MNC) from the SIM card in the device.

For more information about language tags, see <a href="https://tools.ietf.org/html/rfc5646" class="external-link">Tags for Identifying Languages</a>.</p> <p>To use a BCP 47 language tag, concatenate <code translate="no" dir="ltr">b+</code> and a two-letter <a href="http://www.loc.gov/standards/iso639-2/php/code_list.php" class="external-link">ISO 639-1</a> language code, optionally followed by additional subtags separated by <code translate="no" dir="ltr">+</code>.<p> <p>The language tag can change during the life of your app if users change their language in the system settings. For information about how this can affect your app during runtime, see <a href="/guide/topics/resources/runtime-changes">Handle configuration changes</a>.</p> <p>For a complete guide to localizing your app for other languages, See <a href="/guide/topics/resources/localization">Localize your app</a>.</p> <p>Also see the <code translate="no" dir="ltr"><a href="/reference/android/content/res/Configuration#getLocales()"> getLocales()</a></code> method, which provides the defined list of locales.

You can also think of it as the "smallest possible width" for the window. You can use this qualifier so that your app has at least <code translate="no" dir="ltr"><N></code> dps of width available for its UI. </p> <p> For example, if your layout requires that its smallest dimension of screen area be at least 600 dp at all times, then you can use this qualifier to create the layout resources in a <code translate="no" dir="ltr">res/layout-sw600dp/</code> directory. The system uses these resources only when the smallest dimension of available screen is at least 600 dp, regardless of whether the 600 dp side is the user-perceived height or width. The smallest width can change if the window is resized, changing the available width/height, or repositioned, potentially changing the system insets. </p> <p> Using smallest width to determine the general screen size is useful because width is often the driving factor in designing a layout. A UI often scrolls vertically, but has fairly hard constraints on the minimum space it needs horizontally.</p> <p>The available width is also the key factor in determining whether to use a one-pane layout for handsets or a multipane layout for tablets. Thus, you likely care most about what the smallest possible width is on each device. </p> <p> The smallest width of a device takes into account screen decorations and system UI. For example, if the device has persistent UI elements on the screen that account for space along the axis of the smallest width, the system declares the smallest width to be smaller than the actual screen size, because those are screen pixels not available for your UI. </p> <p>Some values you might use here for common screen sizes:</p> <ul> <li>320, for devices with screen configurations such as: <ul> <li>240x320 ldpi (QVGA handset)</li> <li>320x480 mdpi (handset)</li> <li>480x800 hdpi (high-density handset)</li> </ul> </li> <li>480, for screens such as 480x800 mdpi (tablet/handset)</li> <li>600, for screens such as 600x1024 mdpi (7" tablet)</li> <li>720, for screens such as 720x1280 mdpi (10" tablet)</li> </ul> <p>When your app provides multiple resource directories with different values for the <code translate="no" dir="ltr">smallestWidth</code> qualifier, the system uses the one closest to (without exceeding) the device's <code translate="no" dir="ltr">smallestWidth</code>. </p> <p><em>Added in API level 13.</em></p> <p>Also see the <a href="/guide/topics/manifest/supports-screens-element#requiresSmallest"><code translate="no" dir="ltr">android:requiresSmallestWidthDp</code></a> attribute, which declares the minimum <code translate="no" dir="ltr">smallestWidth</code> with which your app is compatible, and the <code translate="no" dir="ltr"><a href="/reference/android/content/res/Configuration#smallestScreenWidthDp">smallestScreenWidthDp</a></code> configuration field, which holds the device's <code translate="no" dir="ltr">smallestWidth</code> value.</p> <p>For more information about designing for different screens using this qualifier, see <a href="/develop/ui/views/layout/responsive-adaptive-design-with-views">Responsive/adaptive design with views</a>.</p> </td> </tr> <tr id="AvailableWidthHeightQualifier"> <td>Available width and height</td> <td><code translate="no" dir="ltr">w<N>dp</code><br/><code translate="no" dir="ltr">h<N>dp</code><br/><br/> Examples:<br/> <code translate="no" dir="ltr">w720dp</code><br/> <code translate="no" dir="ltr">w1024dp</code><br/> <code translate="no" dir="ltr">h720dp</code><br/> <code translate="no" dir="ltr">h1024dp</code><br/> etc. </td> <td> <p>Specifies the minimum available screen width or height (in <code translate="no" dir="ltr">dp</code> units defined by the <code translate="no" dir="ltr"><N></code> value) at which the resource is used. These configuration values are compared to the current display width and height as the device orientation changes between portrait and landscape, the device folds or unfolds, or the system enters or exits multi-window mode. In multi-window mode, the values reflect the width and height of the window that contains the app, not the width and height of the device screen. Similarly, for embedded activities, the values pertain to the width and height of the individual activities, not the width and height of the screen. For more information, see <a href="/guide/topics/large-screens/activity-embedding">Activity embedding</a>.</p> <p>Available width and height are often useful for determining whether to use a multipane layout, because even on a tablet device you often don't want the same multipane layout for portrait orientation as you do for landscape. Thus, you can use these to specify the minimum width and/or height required for the layout, instead of using both the screen size and orientation qualifiers together.</p> <p>When your app provides multiple resource directories with different values for these configurations, the system uses the one closest to (without exceeding) the device's current screen width. <em>Closest to</em> is determined by adding the differences between the actual screen width and the specified width to the difference between the actual screen height and the specified height, with unspecified heights and widths having a value of 0.</p> <p>The values exclude the area occupied by <a href="/reference/android/view/WindowInsets">Window insets</a>, so if the device has persistent UI elements on the edges of the display, the values for width and height are smaller than the real screen dimensions, even when the app is displayed edge to edge using <a href="/reference/android/view/Window#setDecorFitsSystemWindows(boolean)"> <code translate="no" dir="ltr">Window.setDecorFitsSystemWindows</code></a> or <a href="/reference/androidx/core/view/WindowCompat#setDecorFitsSystemWindows(android.view.Window,boolean)"> <code translate="no" dir="ltr">WindowCompat.setDecorFitsSystemWindows</code></a>.</p> <p>Some vertical screen decorations that aren't fixed (such as a phone status bar that can be hidden when full screen) are <em>not</em> accounted for here, nor are window decorations like the title bar or action bar, so apps must be prepared to deal with a somewhat smaller space than they specify.</p> <p class="note"><strong>Note:</strong> The system chooses the resource that matches both in width and height. Therefore a resource that specifies both is strongly preferred over one that specifies only one or the other. For example, if the actual screen is 720 dp wide by 1280 dp high and one resource is qualified with w720dp and another is qualified as w700dp-h1200dp, the latter is chosen even though the former is an exact match for what it specifies. <p><em>Added in API level 13.</em></p> <p>Also see the <code translate="no" dir="ltr"><a href="/reference/android/content/res/Configuration#screenWidthDp">screenWidthDp</a></code> and <code translate="no" dir="ltr"><a href="/reference/android/content/res/Configuration#screenHeightDp">screenHeightDp</a></code> configuration fields, which hold the current screen width and height.</p> <p>For more information about designing for different screens using this qualifier, see <a href="/develop/ui/views/layout/responsive-adaptive-design-with-views">Responsive/adaptive design with views</a>.</p> </td> </tr> <tr id="ScreenSizeQualifier"> <td>Screen size</td> <td> <code translate="no" dir="ltr">small</code><br/> <code translate="no" dir="ltr">normal</code><br/> <code translate="no" dir="ltr">large</code><br/> <code translate="no" dir="ltr">xlarge</code> </td> <td> <ul class="nolist"> <li><code translate="no" dir="ltr">small</code>: screens that are of similar size to a low-density QVGA screen.

For example, <code translate="no" dir="ltr">drawable-en-rUS-land</code> applies to US-English devices in landscape orientation.</li> <li>The qualifiers must be in the order listed in <a href="#table2">table 2</a>. <ul> <li>Wrong: <code translate="no" dir="ltr">drawable-hdpi-port/</code></li> <li>Correct: <code translate="no" dir="ltr">drawable-port-hdpi/</code></li> </ul> </li> <li>Alternative resource directories can't be nested. For example, you can't have <code translate="no" dir="ltr">res/drawable/drawable-en/</code>.</li> <li>Values are case-insensitive. The resource compiler converts directory names to lowercase before processing to avoid problems on case-insensitive file systems. Any capitalization in the names is only to benefit readability.</li> <li>Only one value for each qualifier type is supported. For example, if you want to use the same drawable files for Spain and France, you <em>can't</em> have a directory named <code translate="no" dir="ltr">drawable-es-fr/</code>. Instead, you need two resource directories, such as <code translate="no" dir="ltr">drawable-es/</code> and <code translate="no" dir="ltr">drawable-fr/</code>, which contain the appropriate files. However, you aren't required to actually duplicate the files in both locations. Instead, you can create an <em>alias</em> to a resource, as described in the <a href="#AliasResources">Create alias resources</a> section.</li> </ul> <p>After you save alternative resources into directories named with these qualifiers, Android automatically applies the resources in your app based on the current device configuration. Each time a resource is requested, Android checks for alternative resource directories that contain the requested resource file, then <a href="#BestMatch">finds the best-matching resource</a>.</p> <p>If there are no alternative resources that match a particular device configuration, then Android uses the corresponding default resources—the set of resources for a particular resource type that doesn't include a configuration qualifier.</p> <h3 id="AliasResources" data-text="Create alias resources" tabindex="-1">Create alias resources</h3> <p>When you have a resource that you'd like to use for more than one device configuration but you don't want to provide it as a default resource, you don't need to put the same resource in more than one alternative resource directory. Instead, you can create an alternative resource that acts as an alias for a resource saved in your default resource directory.</p> <p class="note"><strong>Note:</strong> Not all resources offer a mechanism by which you can create an alias to another resource. In particular, animation, menu, raw, and other unspecified resources in the <code translate="no" dir="ltr">xml/</code> directory don't offer this feature.</p> <p>For example, imagine you have an app icon, <code translate="no" dir="ltr">icon.png</code>, and need a unique version of it for different locales. However, two locales, English-Canadian and French-Canadian, need to use the same version. You don't need to copy the same image into the resource directory for both English-Canadian and French-Canadian. Instead, you can save the image that's used for both using any name <em>other than</em> <code translate="no" dir="ltr">icon.png</code>, such as <code translate="no" dir="ltr">icon_ca.png</code>, and put it in the default <code translate="no" dir="ltr">res/drawable/</code> directory. Then create an <code translate="no" dir="ltr">icon.xml</code> file in <code translate="no" dir="ltr">res/drawable-en-rCA/</code> and <code translate="no" dir="ltr">res/drawable-fr-rCA/</code> that refers to the <code translate="no" dir="ltr">icon_ca.png</code> resource using the <code translate="no" dir="ltr"><bitmap></code> element. This lets you store just one version of the PNG file and two small XML files that point to it. See the examples in the following sections for details.</p> <h4 id="drawable" data-text="Drawable" tabindex="-1">Drawable</h4> <p>To create an alias to an existing drawable, use the <code translate="no" dir="ltr"><drawable></code> element:</p> <pre class="prettyprint lang-xml" translate="no" dir="ltr"> <?xml version="1.0" encoding="utf-8"?> <resources> <drawable name="icon">@drawable/icon_ca</drawable> </resources> </pre> <p> If you save this file as <code translate="no" dir="ltr">icon.xml</code> in an alternative resource directory, such as <code translate="no" dir="ltr">res/values-en-rCA/</code>, it is compiled into a resource that you can reference as <code translate="no" dir="ltr">R.drawable.icon</code>, but is actually an alias for the <code translate="no" dir="ltr">R.drawable.icon_ca</code> resource, which is saved in <code translate="no" dir="ltr">res/drawable/</code>. </p> <h4 id="layout" data-text="Layout" tabindex="-1">Layout</h4> <p>To create an alias to an existing layout, use the <code translate="no" dir="ltr"><include></code> element, wrapped in a <code translate="no" dir="ltr"><merge></code>:</p> <pre class="prettyprint lang-xml" translate="no" dir="ltr"> <?xml version="1.0" encoding="utf-8"?> <merge> <include layout="@layout/main_ltr"/> </merge> </pre> <p>If you save this file as <code translate="no" dir="ltr">main.xml</code>, it is compiled into a resource you can reference as <code translate="no" dir="ltr">R.layout.main</code>, but is actually an alias for the <code translate="no" dir="ltr">R.layout.main_ltr</code> resource.</p> <h4 id="strings-and-other-simple-values" data-text="Strings and other simple values" tabindex="-1">Strings and other simple values</h4> <p>To create an alias to an existing string, use the resource ID of the desired string as the value for the new string:</p> <pre class="prettyprint lang-xml" translate="no" dir="ltr"> <?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello">Hello</string> <string name="hi">@string/hello</string> </resources> </pre> <p>The <code translate="no" dir="ltr">R.string.hi</code> resource is now an alias for the <code translate="no" dir="ltr">R.string.hello</code>.</p> <p> <a href="/guide/topics/resources/more-resources">Other simple values</a> work the same way, such as colors:</p> <pre class="prettyprint lang-xml" translate="no" dir="ltr"> <?xml version="1.0" encoding="utf-8"?> <resources> <color name="red">#f00</color> <color name="highlight">@color/red</color> </resources> </pre> <h2 id="Accessing" data-text="Access your app resources" tabindex="-1">Access your app resources</h2> <p>Once you provide a resource in your application, you can apply it by referencing its resource ID.

For a complete guide to localizing your application for other languages, see <a href="/guide/topics/resources/localization">Localize your app</a>.</p> <p>You can even use resources in XML to create aliases. For example, you can create a drawable resource that is an alias for another drawable resource:</p> <pre class="prettyprint lang-xml" translate="no" dir="ltr"> <?xml version="1.0" encoding="utf-8"?> <bitmap xmlns:android="http://schemas.android.com/apk/res/android" android:src="@drawable/other_drawable" /> </pre> <p>This sounds redundant, but can be very useful when using alternative resource. For more information, see the section about <a href="#AliasResources">creating alias resources</a>.</p> <h4 id="ReferencesToThemeAttributes" data-text="Reference style attributes" tabindex="-1">Reference style attributes</h4> <p>A style attribute resource lets you reference the value of an attribute in the currently applied theme. Referencing a style attribute lets you customize the look of UI elements by styling them to match standard variations supplied by the current theme, instead of supplying a hardcoded value. Referencing a style attribute essentially says, "Use the style that is defined by this attribute in the current theme."</p> <p>To reference a style attribute, the name syntax is almost identical to the normal resource format, but instead of the "at" symbol (<code translate="no" dir="ltr">@</code>), use a question mark (<code translate="no" dir="ltr">?</code>). The resource type portion is optional. So the reference syntax is as follows:</p> <pre class="none" translate="no" dir="ltr"> ?[<em><package_name></em>:][<em><resource_type></em>/]<em><resource_name></em> </pre> <p>For example, here's how you can reference an attribute to set the text color to match the secondary text color of the system theme:</p> <pre class="prettyprint lang-xml" translate="no" dir="ltr"> <EditText id="text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="<strong>?android:textColorSecondary</strong>" android:text="@string/hello_world" /> </pre> <p>Here, the <code translate="no" dir="ltr">android:textColor</code> attribute specifies the name of a style attribute in the current theme. Android now uses the value applied to the <code translate="no" dir="ltr">android:textColorSecondary</code> style attribute as the value for <code translate="no" dir="ltr">android:textColor</code> in this widget. Because the system resource tool knows that an attribute resource is expected in this context, you do not need to explicitly state the type, which is <code translate="no" dir="ltr">?android:attr/textColorSecondary</code>. You can exclude the <code translate="no" dir="ltr">attr</code> type.</p> <h3 id="OriginalFiles" data-text="Access original files" tabindex="-1">Access original files</h3> <p>While uncommon, you might need access your original files and directories. If you do, then saving your files in <code translate="no" dir="ltr">res/</code> won't work for you, because the only way to read a resource from <code translate="no" dir="ltr">res/</code> is with the resource ID. Instead, you can save your resources in the <code translate="no" dir="ltr">assets/</code> directory.</p> <p>Files saved in the <code translate="no" dir="ltr">assets/</code> directory are <em>not</em> given a resource ID, so you can't reference them through the <code translate="no" dir="ltr">R</code> class or from XML resources. Instead, you can query files in the <code translate="no" dir="ltr">assets/</code> directory like a normal file system and read raw data using <code translate="no" dir="ltr"><a href="/reference/android/content/res/AssetManager">AssetManager</a></code>.</p> <p>However, if all you require is the ability to read raw data (such as a video or audio file), then save the file in the <code translate="no" dir="ltr">res/raw/</code> directory and read a stream of bytes using <code translate="no" dir="ltr"><a href="/reference/android/content/res/Resources#openRawResource(int)">openRawResource()</a></code>.</p> <h3 id="PlatformResources" data-text="Access platform resources" tabindex="-1">Access platform resources</h3> <p>Android contains a number of standard resources, such as styles, themes, and layouts. To access these resources, qualify your resource reference with the <code translate="no" dir="ltr">android</code> package name. For example, Android provides a layout resource you can use for list items in a <code translate="no" dir="ltr"><a href="/reference/android/widget/ListAdapter">ListAdapter</a></code>:</p> <div> <div class="ds-selector-tabs"><section><h3 id="kotlin" data-text="Kotlin" tabindex="-1">Kotlin</h3> <pre class="prettyprint lang-kotlin" translate="no" dir="ltr"> listAdapter = ArrayAdapter(this, <strong>android.R.layout.simple_list_item_1</strong>, myarray) </pre> </section><section><h3 id="java" data-text="Java" tabindex="-1">Java</h3> <pre class="prettyprint lang-java" translate="no" dir="ltr"> <a href="/reference/android/app/ListActivity#setListAdapter(android.widget.ListAdapter)">setListAdapter</a>(new <a href="/reference/android/widget/ArrayAdapter">ArrayAdapter</a><String>(this, <strong>android.R.layout.simple_list_item_1</strong>, myarray)); </pre> </section></div> </div> <p>In this example, <code translate="no" dir="ltr"><a href="/reference/android/R.layout#simple_list_item_1">simple_list_item_1</a></code> is a layout resource defined by the platform for items in a <code translate="no" dir="ltr"><a href="/reference/android/widget/ListView">ListView</a></code>. You can use this instead of creating your own layout for list items.</p> <h2 id="Compatibility" data-text="Provide the best device compatibility with resources" tabindex="-1">Provide the best device compatibility with resources</h2> <p>For your app to support multiple device configurations, it's very important that you always provide default resources for each type of resource that your app uses.</p> <p>For example, if your app supports several languages, always include a <code translate="no" dir="ltr">values/</code> directory (in which your strings are saved) <em>without</em> a <a href="#LocaleQualifier">language and region qualifier</a>. If you instead put all your string files in directories that have a language and region qualifier, then your app crashes when run on a device set to a language that your strings don't support.</p> <p>As long as you provide default <code translate="no" dir="ltr">values/</code> resources, then your app runs properly, even if the user doesn't understand the language it presents. It's better than crashing.</p> <p>Likewise, if you provide different layout resources based on the screen orientation, pick one orientation as your default. For example, instead of providing layout resources in <code translate="no" dir="ltr">layout-land/</code> for landscape and <code translate="no" dir="ltr">layout-port/</code> for portrait, leave one as the default, such as <code translate="no" dir="ltr">layout/</code> for landscape and <code translate="no" dir="ltr">layout-port/</code> for portrait.</p> <p>Providing default resources is important not only because your app might run on a configuration you hadn't anticipated, but also because new versions of Android sometimes add configuration qualifiers that older versions don't support. If you use a new resource qualifier, but maintain code compatibility with older versions of Android, then when an older version of Android runs your app, it crashes if you don't provide default resources, because it can't use the resources named with the new qualifier.</p> <p>For example, if your <a href="/guide/topics/manifest/uses-sdk-element#min"><code translate="no" dir="ltr">minSdkVersion</code></a> is set to 4, and you qualify all of your drawable resources using <a href="#NightQualifier">night mode</a> (<code translate="no" dir="ltr">night</code> or <code translate="no" dir="ltr">notnight</code>, which were added in API level 8), then an API level 4 device can't access your drawable resources and crashes. In this case, you probably want <code translate="no" dir="ltr">notnight</code> to be your default resources, so exclude that qualifier and put your drawable resources in either <code translate="no" dir="ltr">drawable/</code> or <code translate="no" dir="ltr">drawable-night/</code>.</p> <p>In short, to provide the best device compatibility, always provide default resources for the resources your app needs to perform properly. Then create alternative resources for specific device configurations using configuration qualifiers.</p> <p>There is one exception to this rule: If your app's <a href="/guide/topics/manifest/uses-sdk-element#min"><code translate="no" dir="ltr">minSdkVersion</code></a> is 4 or greater, you <em>don't</em> need default drawable resources when you provide alternative drawable resources with the <a href="#DensityQualifier">screen density</a> qualifier. Even without default drawable resources, Android can find the best match among the alternative screen densities and scale the bitmaps as necessary. However, for the best experience on all types of devices, provide alternative drawables for all three types of density.</p> <h2 id="BestMatch" data-text="How Android finds the best-matching resource" tabindex="-1">How Android finds the best-matching resource</h2> <p>When you request a resource for which you provide alternatives, Android selects which alternative resource to use at runtime, depending on the current device configuration. To demonstrate how Android selects an alternative resource, assume the following drawable directories each contain different versions of the same images:</p> <pre class="none" translate="no" dir="ltr"> drawable/ drawable-en/ drawable-fr-rCA/ drawable-en-port/ drawable-en-notouch-12key/ drawable-port-ldpi/ drawable-port-notouch-12key/ </pre> <p>And assume the following is the device configuration:</p> <p style="margin-left:1em;"> Locale = <code translate="no" dir="ltr">en-GB</code> <br/> Screen orientation = <code translate="no" dir="ltr">port</code> <br/> Screen pixel density = <code translate="no" dir="ltr">hdpi</code> <br/> Touchscreen type = <code translate="no" dir="ltr">notouch</code> <br/> Primary text input method = <code translate="no" dir="ltr">12key</code> </p> <p>By comparing the device configuration to the available alternative resources, Android selects drawables from <code translate="no" dir="ltr">drawable-en-port</code>.</p> <p>The system arrives at its decision for which resources to use with the following logic:</p> <div class="attempt-right" style="width:371px; background:#fff"> <img src="/static/images/resources/res-selection-flowchart.png" alt height="471"> <p class="img-caption"><strong>Figure 2.</strong> Flowchart of how Android finds the best-matching resource.</p> </div> <ol> <li>Eliminate resource files that contradict the device configuration. <p>The <code translate="no" dir="ltr">drawable-fr-rCA/</code> directory is eliminated, because it contradicts the <code translate="no" dir="ltr">en-GB</code> locale.</p> <pre class="none" translate="no" dir="ltr"> drawable/ drawable-en/ <strike>drawable-fr-rCA/</strike> drawable-en-port/ drawable-en-notouch-12key/ drawable-port-ldpi/ drawable-port-notouch-12key/ </pre> <p class="note"><strong>Exception:</strong> Screen pixel density is the one qualifier that is not eliminated due to a contradiction.

(Start with MCC.)</li> <li>Do any of the resource directories include this qualifier? <ul> <li>If no, return to step two and look at the next qualifier. In this example, the answer is "no" until the language qualifier is reached.</li> <li>If yes, continue to step four.</li> </ul> </li> <li>Eliminate resource directories that don't include this qualifier. In this example, the system next eliminates all the directories that don't include a language qualifier: <pre class="none" translate="no" dir="ltr"> <strike>drawable/</strike> drawable-en/ drawable-en-port/ drawable-en-notouch-12key/ <strike>drawable-port-ldpi/</strike> <strike>drawable-port-notouch-12key/</strike> </pre> <p class="note"><strong>Exception:</strong> If the qualifier in question is screen pixel density, Android selects the option that most closely matches the device screen density. In general, Android prefers scaling down a larger original image to scaling up a smaller original image. For more information, see <a href="/guide/practices/screens_support">Screen compatibility overview</a>.</p> </li> <li>Repeat steps two, three, and four until only one directory remains. In this example, screen orientation is the next qualifier for which there are any matches. So, resources that don't specify a screen orientation are eliminated: <pre class="none" translate="no" dir="ltr"> <strike>drawable-en/</strike> drawable-en-port/ <strike>drawable-en-notouch-12key/</strike> </pre> <p>The remaining directory is <code translate="no" dir="ltr">drawable-en-port</code>.</p> </li> </ol> <p>Though this procedure is executed for each resource requested, the system optimizes some aspects of it. One such optimization is that once the device configuration is known, it might eliminate alternative resources that can never match. For example, if the configuration language is English, then any resource directory that has a language qualifier set to something other than English is never included in the pool of resources checked (though a resource directory <em>without</em> the language qualifier is still included).</p> <p>When selecting resources based on the screen size qualifiers, the system uses resources designed for a screen smaller than the current screen if there are no resources that better match. For example, a large-size screen uses normal-size screen resources if necessary.</p> <p>However, if the only available resources are <em>larger</em> than the current screen, the system <strong>doesn't</strong> use them and your app crashes if no other resources match the device configuration. This happens, for example, if all layout resources are tagged with the <code translate="no" dir="ltr">xlarge</code> qualifier, but the device is a normal-size screen.</p> <p class="note"><strong>Note:</strong> The <em>precedence</em> of the qualifier (in <a href="#table2">table 2</a>) is more important than the number of qualifiers that exactly match the device. In the preceding example, at step four the last choice on the list includes three qualifiers that exactly match the device (orientation, touchscreen type, and input method), while <code translate="no" dir="ltr">drawable-en</code> has only one parameter that matches (language). However, language has a higher precedence than these other qualifiers, so <code translate="no" dir="ltr">drawable-port-notouch-12key</code> is eliminated.</p> <devsite-hats-survey class="nocontent" hats-id="VxqvKSur40kxBYCLVTd0SSGykbno" listnr-id="5207477"></devsite-hats-survey> </div> <devsite-recommendations display="in-page" hidden yield> </devsite-recommendations> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-recommendations id="recommendations-link" yield></devsite-recommendations> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> <p>Content and code samples on this page are subject to the licenses described in the <a href="/license">Content License</a>.
