If your app needs to use resources or information outside of its own sandbox, you can <a href="/web/20231022203011/https://developer.android.com/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="/web/20231022203011/https://developer.android.com/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't directly related to user privacy. For these <a href="/web/20231022203011/https://developer.android.com/training/permissions/requesting-special">special permissions</a>, follow a different process.</span></aside> <p>If you declare any <a href="/web/20231022203011/https://developer.android.com/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'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't need to complete any of the remaining steps on this page.</p> <h2 id="principles" data-text="Basic principles">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'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't assume any system behavior. For example, don'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">Workflow for requesting permissions</h2> <p>Before you declare and request runtime permissions in your app, <a href="/web/20231022203011/https://developer.android.com/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's manifest file, <a href="/web/20231022203011/https://developer.android.com/training/permissions/declaring">declare the permissions</a> that your app might need to request.</li> <li>Design your app'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'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'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.

When a foreground service is running, the system raises user awareness by showing a persistent notification.

When you do so, keep the following best practices in mind:</p> <ul> <li><p><strong>Guide the user's attention.</strong> Highlight a specific part of your app's UI where there's limited functionality because your app doesn't have the necessary permission.

Instead, make clear which features are unavailable because your app doesn't have the necessary permission.</p></li> <li><p><strong>Don't block the user interface.</strong> In other words, don'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's decision to deny a permission. Starting in Android 11 (API level 30), if the user taps <strong>Deny</strong> for a specific permission more than once during your app's lifetime of installation on a device, the user doesn't see the system permissions dialog if your app requests that permission again. The user's action implies "don't ask again." On previous versions, users saw the system permissions dialog each time your app requested a permission, unless they had previously selected a "don't ask again" checkbox or option.</p> <p>If a user denies a permission request more than once, this is considered a permanant denial. It'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'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="/web/20231022203011/https://developer.android.com/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">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> <pre class="none" translate="no" dir="ltr">adb shell dumpsys package <var translate="no">PACKAGE_NAME</var></pre> <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> <pre class="none" translate="no" dir="ltr"> ... 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> <p>Permissions that have been denied once by the user are flagged by <code translate="no" dir="ltr">USER_SET</code>.

As with any permission, if the user revokes your app's one-time permission, your app's process terminates.</p> <p>When the user next opens your app and a feature in your app requests access to location, microphone, or camera, the user is prompted for the permission again.</p> <aside class="note"><strong>Note:</strong><span> If your app already follows <a href="/web/20231022203011/https://developer.android.com/training/permissions/usage-notes">best practices</a> when it requests runtime permissions, you don't need to add or change any logic in your app to support one-time permissions.</span></aside> <h2 id="reset-unused-permissions" data-text="Reset unused permissions">Reset unused permissions</h2> <p>Android provides several ways to reset unused runtime permissions to their default, denied state:</p> <ul> <li>An API where you can proactively <a href="#remove-access">remove your app's access</a> to an unused runtime permission.</li> <li>A system mechanism that automatically <a href="#auto-reset-permissions-unused-apps">resets the permissions of unused apps</a>.</li> </ul> <h3 id="remove-access" data-text="Remove app access">Remove app access</h3> <p>On Android 13 (API level 33) and higher, you can remove your app's access to runtime permissions that your app no longer requires. When you update your app, perform this step so that users are more likely to understand why your app continues to request specific permissions. This knowledge helps build user trust in your app.</p> <p>To remove access to a runtime permission, pass the name of that permission into <a href="/web/20231022203011/https://developer.android.com/reference/android/content/Context#revokeSelfPermissionOnKill(java.lang.String)"><code translate="no" dir="ltr">revokeSelfPermissionOnKill()</code></a>. To remove access to a group of runtime permissions at the same time, pass a collection of permission names into <a href="/web/20231022203011/https://developer.android.com/reference/android/content/Context#revokeSelfPermissionsOnKill(java.util.Collection%3Cjava.lang.String%3E)"><code translate="no" dir="ltr">revokeSelfPermissionsOnKill()</code></a>. The permission removal process happens asynchronously and kills all processes associated with your app's UID.</p> <aside class="note"><strong>Note:</strong><span> For system settings to show that your app doesn't access data in a particular <a href="/web/20231022203011/https://developer.android.com/reference/android/Manifest.permission_group">permission group</a>, you must remove access to <strong>all</strong> permissions in that permission group. In this case, it can be helpful to call <code translate="no" dir="ltr">revokeSelfPermissionsOnKill()</code> and pass in multiple permissions within the permission group.</span></aside> <p>For the system to remove your app's access to the permissions, all processes tied to your app must be killed. When you call the API, the system determines when it's safe to kill these processes. Usually, the system waits until your app spends an extended period of time running in the background instead of the foreground.</p> <p>To inform the user that your app no longer requires access to specific runtime permissions, show a dialog the next time the user launches your app. This dialog can include the list of permissions.</p> <h3 id="auto-reset-permissions-unused-apps" data-text="Auto-reset permissions of unused apps">Auto-reset permissions of unused apps</h3> <p>If your app targets Android 11 (API level 30) or higher and isn't used for a few months, the system protects user data by automatically resetting the sensitive runtime permissions that the user had granted your app. Learn more in the guide about <a href="/web/20231022203011/https://developer.android.com/topic/performance/app-hibernation">app hibernation</a>.</p> <h2 id="request-default-handler" data-text="Request to become the default handler if necessary">Request to become the default handler if necessary</h2> <p>Some apps depend on access to sensitive user information related to call logs and SMS messages.
