sandbox. If your app needs to use resources or information outside of its own sandbox, you can <a href="/training/permissions/declaring">declare a runtime permission</a> and set up a permission request that provides this access. These steps are part of the <a href="/training/basics/permissions#workflow">workflow for using permissions</a>.</p> <aside class="note"><strong>Note:</strong><span> Some permissions guard access to system resources that are particularly sensitive or aren&#39;t directly related to user privacy. For these <a href="/training/permissions/requesting-special">special permissions</a>, follow a different process.</span></aside> <p>If you declare any <a href="/guide/topics/permissions/overview#dangerous_permissions">dangerous permissions</a>, and if your app is installed on a device that runs Android 6.0 (API level 23) or higher, you must request the dangerous permissions at runtime by following the steps in this guide.</p> <p>If you don&#39;t declare any dangerous permissions, or if your app is installed on a device that runs Android 5.1 (API level 22) or lower, the permissions are automatically granted, and you don&#39;t need to complete any of the remaining steps on this page.</p> <h2 id="principles" data-text="Basic principles" tabindex="-1">Basic principles</h2> <p>The basic principles for requesting permissions at runtime are as follows:</p> <ul> <li>Ask for a permission in context, when the user starts to interact with the feature that requires it.</li> <li>Don&#39;t block the user. Always provide the option to cancel an educational UI flow, such as a flow that explains the rationale for requesting permissions.</li> <li>If the user denies or revokes a permission that a feature needs, gracefully degrade your app so that the user can continue using your app, possibly by disabling the feature that requires the permission.</li> <li>Don&#39;t assume any system behavior. For example, don&#39;t assume that permissions appear in the same <em>permission group</em>. A permission group merely helps the system minimize the number of system dialogs that are presented to the user when an app requests closely related permissions.</li> </ul> <h2 id="workflow_for_requesting_permissions" data-text="Workflow for requesting permissions" tabindex="-1">Workflow for requesting permissions</h2> <p>Before you declare and request runtime permissions in your app, <a href="/training/permissions/evaluating">evaluate whether your app needs to do so</a>. You can fulfill many use cases in your app, such as taking photos, pausing media playback, and displaying relevant ads, without needing to declare any permissions.</p> <p>If you conclude that your app needs to declare and request runtime permissions, complete these steps:</p> <ol> <li>In your app&#39;s manifest file, <a href="/training/permissions/declaring">declare the permissions</a> that your app might need to request.</li> <li>Design your app&#39;s UX so that specific actions in your app are associated with specific runtime permissions. Let users know which actions might require them to grant permission for your app to access private user data.</li> <li><a href="#principles">Wait for the user</a> to invoke the task or action in your app that requires access to specific private user data. At that time, your app can request the runtime permission that&#39;s required for accessing that data.</li> <li><p><a href="#already-granted">Check whether the user has already granted the runtime permission</a> that your app requires. If so, your app can access the private user data. If not, continue to the next step.</p> <p>You must check whether you have a permission every time you perform an operation that requires that permission.</p></li> <li><p><a href="#explain">Check whether your app should show a rationale</a> to the user, explaining why your app needs the user to grant a particular runtime permission. If the system determines that your app shouldn&#39;t show a rationale, continue to the next step directly, without showing a UI element.</p> <p>If the system determines that your app should show a rationale, however, present the rationale to the user in a UI element. In this rationale, clearly explain what data your app is trying to access and what benefits the app can provide to the user if they grant the runtime permission. After the user acknowledges the rationale, continue to the next step.</p></li> <li><p><a href="#request-permission">Request the runtime permission</a> that your app requires to access the private user data. The system displays a runtime permission prompt, such as the one shown on the <a href="/guide/topics/permissions/overview#fig-runtime">permissions overview page</a>.</p></li> <li><p>Check the user&#39;s response&mdash;whether they chose to grant or deny the runtime permission.</p></li> <li><p>If the user granted the permission to your app, you can access the private user data. If the user denied the permission instead, <a href="#handle-denial">gracefully degrade your app experience</a> so that it provides functionality to the user without the information that&#39;s protected by that permission.</p></li> </ol> <p>Figure 1 illustrates the workflow and set of decisions associated with this process:</p> <figure id="fig-workflow"> <img src="/static/images/training/permissions/workflow-runtime.svg" width="900" alt="" class="android-image-dark-theme-background"> <figcaption><b>Figure 1.</b> Diagram that shows the workflow for declaring and requesting runtime permissions on Android.</figcaption> </figure> <h2 id="already-granted" data-text="Determine whether your app was already granted the permission" tabindex="-1">Determine whether your app was already granted the permission</h2> <p>To check whether the user already granted your app a particular permission, pass that permission into the <a href="/reference/androidx/core/content/ContextCompat#checkSelfPermission(android.content.Context,%20java.lang.String)"><code translate="no" dir="ltr">ContextCompat.checkSelfPermission()</code></a> method. This method returns either <a href="/reference/android/content/pm/PackageManager#PERMISSION_GRANTED"><code translate="no" dir="ltr">PERMISSION_GRANTED</code></a> or <a href="/reference/android/content/pm/PackageManager#PERMISSION_DENIED"><code translate="no" dir="ltr">PERMISSION_DENIED</code></a>, depending on whether your app has the permission.</p> <h2 id="explain" data-text="Explain why your app needs the permission" tabindex="-1">Explain why your app needs the permission</h2> <p> The permissions dialog shown by the system when you call <code translate="no" dir="ltr"><a href="/reference/androidx/core/app/ActivityCompat#requestPermissions(android.app.Activity, java.lang.String[], int)">requestPermissions()</a></code> says what permission your app wants, but doesn't say why. In some cases, the user might find that puzzling. It's a good idea to explain to the user why your app wants the permissions before you call <code translate="no" dir="ltr">requestPermissions()</code>. </p> <p> Research shows that users are much more comfortable with permissions requests if they know why the app needs them, such as whether the permission is needed to support a core feature of the app or for advertising. As a result, if you're only using a fraction of the API calls that fall under a permission group, it helps to explicitly list which of those permissions you're using and why. For example, if you're only using coarse location, let the user know this in your app description or in help articles about your app. </p> <p> Under certain conditions, it's also helpful to let users know about sensitive data access in real time. For example, if you’re accessing the camera or microphone, it’s a good idea to let the user know by using a notification icon somewhere in your app, or in the notification tray (if the application is running in the background), so it doesn't seem like you're collecting data surreptitiously. </p> <aside class="note"><strong>Note:</strong><span> Starting in Android 12 (API level 31), <a href="/training/permissions/explaining-access#indicators">privacy indicators</a> notify the user whenever applications access the microphone or camera.</span></aside> <p> Ultimately, if you need to request a permission to make something in your app work, but the reason isn't clear to the user, find a way to let the user know why you need the most sensitive permissions. </p> <p>If the <code translate="no" dir="ltr">ContextCompat.checkSelfPermission()</code> method returns <code translate="no" dir="ltr">PERMISSION_DENIED</code>, call <a href="/reference/androidx/core/app/ActivityCompat#shouldShowRequestPermissionRationale(android.app.Activity,%20java.lang.String)"><code translate="no" dir="ltr">shouldShowRequestPermissionRationale()</code></a>. If this method returns <code translate="no" dir="ltr">true</code>, show an educational UI to the user.

One important difference when it comes to location permissions is that the system includes multiple permissions related to location. Which permissions you request, and how you request them, depend on the location requirements for your app&#39;s use case.</p> <h4 id="foreground" data-text="Foreground location" tabindex="-1">Foreground location</h4> <p>If your app contains a feature that shares or receives location information only once, or for a defined amount of time, then that feature requires foreground location access. Some examples include the following:</p> <ul> <li>Within a navigation app, a feature lets users get turn-by-turn directions.</li> <li>Within a messaging app, a feature lets users share their current location with another user.</li> </ul> <p>The system considers your app to be using foreground location if a feature of your app accesses the device&#39;s current location in one of the following situations:</p> <ul> <li>An activity that belongs to your app is visible.</li> <li><p>Your app is running a foreground service.

In particular, your app should make users aware of the features that don&#39;t work because of the missing permission. When you do so, keep the following best practices in mind:</p> <ul> <li><p><strong>Guide the user&#39;s attention.</strong> Highlight a specific part of your app&#39;s UI where there&#39;s limited functionality because your app doesn&#39;t have the necessary permission. Examples of what you could do include the following:</p> <ul> <li>Show a message where the feature&#39;s results or data would have appeared.</li> <li>Display a different button that contains an error icon and color.</li> </ul></li> <li><p><strong>Be specific.</strong> Don&#39;t display a generic message. Instead, make clear which features are unavailable because your app doesn&#39;t have the necessary permission.</p></li> <li><p><strong>Don&#39;t block the user interface.</strong> In other words, don&#39;t display a full-screen warning message that prevents users from continuing to use your app at all.</p></li> </ul> <aside class="tip"><strong>Tip:</strong><span> Your app should encourage the best user experience possible, even after permission denials. For example, if microphone access is denied, you should still promote full usability of text functionality.</span></aside> <p>At the same time, your app should respect the user&#39;s decision to deny a permission. Starting in Android&nbsp;11 (API level&nbsp;30), if the user taps <strong>Deny</strong> for a specific permission more than once during your app&#39;s lifetime of installation on a device, the user doesn&#39;t see the system permissions dialog if your app requests that permission again. The user&#39;s action implies &quot;don&#39;t ask again.&quot; On previous versions, users saw the system permissions dialog each time your app requested a permission, unless they had previously selected a &quot;don&#39;t ask again&quot; checkbox or option.</p> <p>If a user denies a permission request more than once, this is considered a permanant denial. It&#39;s very important to only prompt users for permissions when they need access to a specific feature, otherwise you might inadvertently lose the ability to re-request permissions.</p> <p>In certain situations, the permission might be denied automatically, without the user taking any action. (A permission might be <em>granted</em> automatically as well.) It&#39;s important to not assume anything about automatic behavior. Each time your app needs to access functionality that requires a permission, check that your app is still granted that permission.</p> <p>To provide the best user experience when asking for app permissions, also see <a href="/training/permissions/usage-notes">App permissions best practices</a>.</p> <h3 id="inspect_denial_status_when_testing_and_debugging" data-text="Inspect denial status when testing and debugging" tabindex="-1">Inspect denial status when testing and debugging</h3> <p>To identify whether an app has been permanently denied permissions (for debugging and testing purposes), use the following command:</p> <div></div><devsite-code><pre class="none" translate="no" dir="ltr" is-upgraded>adb shell dumpsys package <var translate="no">PACKAGE_NAME</var></pre></devsite-code> <p>Where <var translate="no">PACKAGE_NAME</var> is the name of the package to inspect.</p> <p>The output of the command contains sections that look like this:</p> <div></div><devsite-code><pre class="none" translate="no" dir="ltr" is-upgraded> ... runtime permissions: android.permission.POST_NOTIFICATIONS: granted=false, flags=[ USER_SENSITIVE_WHEN_GRANTED|USER_SENSITIVE_WHEN_DENIED] android.permission.ACCESS_FINE_LOCATION: granted=false, flags=[ <var translate="no">USER_SET</var>|<var translate="no">USER_FIXED</var>|USER_SENSITIVE_WHEN_GRANTED|USER_SENSITIVE_WHEN_DENIED] android.permission.BLUETOOTH_CONNECT: granted=false, flags=[ USER_SENSITIVE_WHEN_GRANTED|USER_SENSITIVE_WHEN_DENIED] ... </pre></devsite-code> <p>Permissions that have been denied once by the user are flagged by <code translate="no" dir="ltr">USER_SET</code>.
