Compatibility framework changes (Android 11)

This page describes each app-impacting behavior change that was added to the compatibility framework in Android 11 (API level 30). Use this list in conjunction with the developer options and ADB commands to test and debug your app as you prepare to target Android 11.

ADD_CONTENT_OBSERVER_FLAGS

Change ID: 150939131

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11, there is a new public API overload onChange(boolean, Uri, int) that includes an integer flags argument.

This new method is a public SDK alternative for apps that use the non-SDK onChange() overloaded method that includes an integer userId argument.

ADMIN_APP_PASSWORD_COMPLEXITY

Change ID: 123562444

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For admin apps targeting Android 11, throw an error whenever an app sets a password requirement that is not relevant to the currently assigned password quality. For example, when the password quality is set to DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED, an app would not be able to set a minimum password length. In this case, before trying to set the minimum password length, the app should first call the setPasswordQuality() method and only then call the setPasswordMinimumLength() method.

In addition, when an admin app targeting Android 11 lowers the password quality, any existing password requirements that no longer apply are reset to their default values.

APP_DATA_DIRECTORY_ISOLATION

Change ID: 143937733

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Apps that target Android 11 can no longer access files in private data directories of any app, regardless of the other app's target SDK version.

To learn more, see Access to private directories.

APN_READING_PERMISSION_CHANGE_ID

Change ID: 124107808

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11, accessing the APN database now requires the Manifest.permission.WRITE_APN_SETTINGS permission.

To learn more about this change, see Restricted read access to APN database.

BACKGROUND_RATIONALE_CHANGE_ID

Change ID: 147316723

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Apps must now provide a valid rationale every time they request to access the device's location in the background.

To learn more about this change, see the guide on how to Access background location in Android 11 that discusses privacy changes related to location in Android 11.

CALLBACK_ON_CLEAR_CHANGE

Change ID: 119147584

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Whenever Editor.clear is called, a callback is now made to OnSharedPreferenceChangeListener.onSharedPreferenceChanged with a null key.

To learn more about this change, see Callback changes for OnSharedPreferenceChangeListener.

CALLBACK_ON_MORE_ERROR_CODE_CHANGE

Change ID: 130595455

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

The error codes are now expanded for updateAvailableNetworks(List, Executor, Consumer) and setPreferredOpportunisticDataSubscription(int, boolean, Executor, Consumer).

CALL_BACK_ON_CHANGED_LISTENER_WITH_SWITCHED_OP_CHANGE

Change ID: 148180766

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

This is a subtle behavior change to startWatchingMode(String, String, AppOpsManager.OnOpChangedListener). Before this change the system called back for the switched op. After the change the system will call back for the actually requested op or all switched ops if no op is specified.

CAMERA_MICROPHONE_CAPABILITY_CHANGE_ID

Change ID: 136219221

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11, foreground services only receive camera and microphone while-in-use capabilities when the R.attr.foregroundServiceType is configured as ServiceInfo.FOREGROUND_SERVICE_TYPE_CAMERA and ServiceInfo.FOREGROUND_SERVICE_TYPE_MICROPHONE respectively in the manifest file. On earlier versions of Android, foreground services automatically received camera and microphone capabilities.

To learn more about this change, see Foreground service types in Android 11.

CHANGE_BACKGROUND_CUSTOM_TOAST_BLOCK

Change ID: 128611929

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Apps can no longer post custom toasts in the background. However, apps can still post toasts using the Toast.makeText(Context, CharSequence, int) method and its variants while in the background.

To learn more about this change, see Custom toast views are blocked.

CHANGE_RESTRICT_SAW_INTENT

Change ID: 135920175

Default state: This change can't be toggled. It is only logged by the compatibility framework.

Intents using the android.settings.MANAGE_APP_OVERLAY_PERMISSION action and the package data URI scheme no longer direct the user to an app-specific screen for managing the associated permission. Instead, the user is directed to a screen where they can manage all the apps that have requested the permission.

CHANGE_TEXT_TOASTS_IN_THE_SYSTEM

Change ID: 147798919

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Text toasts are now rendered by the SystemUI instead of in-app. This prevents apps from circumventing restrictions on posting custom toasts in the background.

DEFAULT_SCOPED_STORAGE

Change ID: 149924527

Default state: Enabled for all apps.

All apps targeting Android 11 now use scoped storage by default and can no longer opt out of scoped storage.

However, you can test your app without scoped storage, regardless of your app's target SDK version and manifest flag values, by toggling this change off.

To learn more about the changes to scoped storage in Android 11, see the Scoped storage section on the page about changes to Android storage in Android 11.

EMPTY_INTENT_ACTION_CATEGORY

Change ID: 151163173

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11, the system now throws an error if an intent filter's action or category is an empty string. A bug in the platform before Android 11 allowed this case to pass through without throwing an error. Note that this does not include cases when the attribute is null or missing, as that has always thrown an error.

FILTER_APPLICATION_QUERY

Change ID: 135549675

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Apps now need to declare the packages and intents they intend to use before they can get details about other apps on a device. Such declarations must be made using the <queries> tag in the app's manifest.

To learn more about how to query and interact with other installed apps in Android 11, see the package visibility privacy page.

FORCE_ENABLE_SCOPED_STORAGE

Change ID: Value: 132649864

Default state: Disabled for all apps.

All apps targeting Android 11 now use scoped storage by default and can no longer opt out of scoped storage.

However, if your app still targets Android 10 (API level 29) or lower, you can test your app with scoped storage, regardless of your app's target SDK version and manifest flag values, by toggling this change on.

To learn more about the changes to scoped storage in Android 11, see the Scoped storage section on the page about changes to Android storage in Android 11.

GET_DATA_CONNECTION_STATE_R_VERSION

Change ID: 148535736

For apps targeting Android 11 (API level 30) or higher, getProvider(String) no longer throws any security exceptions.

GET_TARGET_SDK_VERSION_CODE_CHANGE

Change ID: 145147528

Default state: Enabled for apps that target Android 10 (API level 29) or higher.

To check the SDK version for the SmsManager.sendResolverResult() method.

GWP_ASAN

Change ID: 135634846

Default state: Disabled for all apps.

Enables sampled native memory bug detection in apps.

To learn more about this change, see the GWP-ASan guide.

HIDE_MAXTARGETSDK_P_HIDDEN_APIS

Change ID: 149997251

Default state: Enabled for apps that target Android 10 (API level 29) or higher.

For apps targeting Android 10 (API level 29) or higher, removes access to all non-SDK interfaces that are part of the max-target-p (greylist-max-p) list for Android 10 (API level 29).

HIDE_MAXTARGETSDK_Q_HIDDEN_APIS

Change ID: 149994052

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11 (API level 30) or higher, removes access to all non-SDK interfaces that are part of the max-target-q (greylist-max-q) list for Android 11 (API level 30).

NATIVE_HEAP_POINTER_TAGGING

Change ID: 135754954

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11, native heap allocations now have a non-zero tag in the most significant byte.

To learn more, see Heap pointer tagging.

PHONE_STATE_LISTENER_LIMIT_CHANGE_ID

Change ID: 150880553

Default state: Enabled for all apps.

For apps targeting Android 11, there is now a limit on the number of PhoneStateListener objects any process may register via TelephonyManager.listen(PhoneStateListener, int). The default limit is 50, which may change via remote device config updates. This limit is enforced via an IllegalStateException thrown from TelephonyManager.listen(PhoneStateListener, int) when the offending process attempts to register one too many listeners.

PREVENT_META_REFLECTION_BLACKLIST_ACCESS

Change ID: 142365358

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Apps targeting Android 11 can no longer use an extra layer of reflection to access non-SDK interfaces that are restricted.

For apps targeting Android 11, the flag Context.BIND_INCLUDE_CAPABILITIES can now be used to pass while-in-use capabilities from the client process to a bound service.

REMOVE_ANDROID_TEST_BASE

Change ID: 133396946

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For apps targeting Android 11, the android.test.base library has been removed if the app does not depend on android.test.runner (as it depends on classes from the android.test.base library).

REQUEST_ACCESSIBILITY_BUTTON_CHANGE

Change ID: 136293963

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

For accessibility services targeting Android 11, the FLAG_REQUEST_ACCESSIBILITY_BUTTON flag must now be specified in the accessibility service metadata file. Otherwise, the flag is ignored.

RESOURCES_ARSC_COMPRESSED

Change ID: 132742131

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Apps targeting Android 11 (API level 30) can't be installed if they contain a compressed resources.arsc file or if this file is not aligned on a 4-byte boundary.

To learn more about this change, see Compressed resource files.

RESTRICT_STORAGE_ACCESS_FRAMEWORK

Change ID: 141600225

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

If your app targets Android 11 and uses the Storage Access Framework (SAF), you can no longer access certain directories using the ACTION_OPEN_DOCUMENT and ACTION_OPEN_DOCUMENT_TREE intent actions. To learn more about these changes, see the Document access restrictions section on the page that discusses privacy updates related to storage in Android 11.

SELINUX_LATEST_CHANGES

Change ID: 143539591

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

This change gates apps access to the untrusted_app_R-targetSDk SELinux domain. This is one of the foundational changes in the compatibility framework that allow apps to toggle other changes that are gated by targetSdkVersion without changing their app's targetSDKVersion. For this reason, you should not disable this change for an app that targets Android 11, or the app will not function.

This change has no effect for apps that use a shared user ID.

THROW_SECURITY_EXCEPTIONS

Change ID: 147340954

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Prior to Android 11, a SecurityException would only be thrown by setEnabled APIs for a permission error. In Android 11 this no longer holds true, and a SecurityException can be thrown for any number of reasons, none of which are exposed to the caller.

To maintain existing API behavior, if a legacy permission failure or actor enforcement failure occurs for an app that does not target Android 11, the exception is coerced into an IllegalStateException that existed in the source prior to Android 11.

USE_SET_LOCATION_ENABLED

Change ID: 117835097

Default state: Enabled for apps that target Android 11 (API level 30) or higher.

Admin apps targeting Android 11 can no longer use DevicePolicyManager.setSecureSetting(ComponentName, String, String) to change the deprecated Settings.Secure.LOCATION_MODE setting. Instead they should use DevicePolicyManager.setLocationEnabled(ComponentName, boolean).
