This change is necessary to supportfuture hardware with ARM Memory Tagging Extension (MTE) enabled. To learn more, seeTagged Pointers.

To disable this feature, see the allowNativeHeapPointerTaggingmanifest documentation.

Updates to toasts

Custom toasts from the background are blocked

For security reasons and to maintain a good user experience, the system blockstoasts that contain custom views if those toasts are sent from the background byan app that targets Android 11 or higher. Note that text toastsare still allowed; these are toasts created usingToast.makeText() thatdon't call setView().

If your app tries to post a toast containing a custom view from the backgroundanyway, the system doesn't show the message to the user. Instead, the systemlogs the following message in logcat:

Toast callbacks

If you want to be notified when a toast (text or custom) appears or disappears,use theaddCallback()method, which was added in Android 11.

Text toast API changes

Apps that target Android 11 or higher see the following sideeffects for text toasts:

• The getView() methodreturns null.
• The return values of the following methods don't reflect the actual values, soyou shouldn't rely on them in your app:
• The following methods are no-ops, so your app shouldn't use them:

Accessibility

Declare interaction with TTS engines in manifest file

Because of changes to packagevisibility, apps that targetAndroid 11 and interact with a text-to-speech (TTS) engine needto add the following <queries> element to their manifest files:

Declare accessibility button usage in metadata file

Change details

How to toggle

As you test your app's compatibility with Android 11, you can toggle this change on or off using the following ADB commands:

For more information about the compatibility framework and toggling changes, see Test and debug platform behavior changes in your app.

Starting in Android 11, your accessibility service cannot makea runtime declaration that it has an association with the system'saccessibility button. If youappend AccessibilityServiceInfo.FLAG_REQUEST_ACCESSIBILITY_BUTTON to theflags property of an AccessibilityServiceInfo object, the framework doesn'tpass accessibility button callback events to your service.

To receive accessibility callback events in your accessibility service, use youraccessibility service metadata file to declare your service's association withthe accessibility button. Include the flagRequestAccessibilityButton value inyour definition of theaccessibilityFlagsattribute. A common location for the accessibility service metadata file isres/raw/accessibilityservice.xml.

Camera

Media intent actions require system default camera

Starting in Android 11, only pre-installed system camera apps canrespond to the following intent actions:

If more than one pre-installed system camera app is available, the systempresents a dialog for the user to select an app. If you want your app to use aspecific third-party camera app to capture images or videos on its behalf, youcan make these intents explicit by setting a package name or component for theintent.

For more information about the compatibility framework and toggling changes, see Test and debug platform behavior changes in your app.

Apps that target Android 11 (API level 30) or higher can't be installed if theycontain a compressedresources.arsc file or if this file is not aligned ona 4-byte boundary. This file cannot be memory-mapped by the system if either ofthese conditions is present. Resources tables that cannot be memory-mapped mustbe read into a buffer in RAM resulting in unnecessary memory pressure on thesystem and greatly increased device RAM usage.

APK Signature Scheme v2 now required

Apps that target Android 11 (API level 30) that are currently only signed usingAPK Signature Scheme v1 must now also be signed using APKSignature Scheme v2 orhigher. Users can't install or update apps that are only signed with APKSignature Scheme v1 on devices that run Android 11.

To verify that your app is being signed with APK Signature Scheme v2 or higher,you can use either Android Studio,or the apksigner tool on the command line.

Firebase

Firebase JobDispatcher and GCMNetworkManager

If your app targets API level 30 or higher, FirebaseJobDispatcher and GcmNetworkManager API calls are disabled on devicesrunning Android 6.0 (API level 23) or higher. For migration information, seeMigrating from Firebase JobDispatcher toWorkManager andMigrating from GCMNetworkManager toWorkManager.

Because of changes to packagevisibility, apps that targetAndroid 11 and interact with a speech recognition service needto add the following <queries> element to their manifest files:

Device-to-device file transfer

If your app targets Android 11 or higher, you cannot disabledevice-to-device migration of your app's files using theallowBackupattribute. The system automatically allows this functionality.

Callback changes for OnSharedPreferenceChangeListener

Change details

Change Name: CALLBACK_ON_CLEAR_CHANGE

Change ID: 119147584

How to toggle

As you test your app's compatibility with Android 11, you can toggle this change on or off using the following ADB commands:

Non-SDK interface restrictions

Android 11 includes updated lists of restricted non-SDKinterfaces based on collaboration with Android developers and the latestinternal testing. Whenever possible, we make sure that public alternatives areavailable before we restrict non-SDK interfaces.

If your app does not target Android 11, some of these changesmight not immediately affect you. However, while you can currently use somenon-SDK interfaces (depending on your app's target API level),using any non-SDK method or field always carries a high risk of breaking yourapp.

If you are unsure if your app uses non-SDK interfaces, you can test yourappto find out. If your app relies on non-SDK interfaces, you should begin planninga migration to SDK alternatives. Nevertheless, we understand that some apps havevalid use cases for using non-SDK interfaces. If you cannot find an alternativeto using a non-SDK interface for a feature in your app, you should request anew public API.
