![](https://developer.android.com/static/about/versions/16/images/app-compat-dev-options-16.png) **Figure 1**. The App Compatibility Changes screen in developer options lists the changes that you can toggle.

This page describes toggleable changes that are part of the compatibility
framework in Android 16 (API level 36). Use this list in conjunction with the
[developer options and ADB commands](https://developer.android.com/guide/app-compatibility/test-debug) to
test and debug your app as you prepare to support and target Android 16.

Here are some of the things you can do using the compatibility framework tools:

- **Test targeted changes without actually changing the app's
  targetSdkVersion**. You can use the toggles to force-enable specific targeted behavior changes to evaluate the impact on your existing app.
- **Focus your testing on specific changes only**. Rather than having to address all targeted changes at once, the toggles let you disable all targeted changes except the ones you want to test against.
- **Manage toggles through adb**. You can use adb commands to enable and disable the toggleable changes in your automated test environment.
- **Debug faster using standard change IDs**. Toggleable changes each have a unique ID and name that you can use to quickly debug root cause in log output.

For complete details on using the tools for each of these use cases, see
[Compatibility framework tools](https://developer.android.com/guide/app-compatibility/test-debug).

## Behavior changes included in the compatibility framework

The list in this section describes toggleable changes that are included in the
compatibility framework for Android 16-related changes and toggleable changes
that can help with general app testing.

You can filter the list of changes by their **Default State**.

| Toggleable changes in the compatibility framework in Android 16 |
|---|
| ### `CAMERA_MIC_INDICATORS_NOT_PRESENT` **Change ID:** 162547999 **Default State** : Disabled for all apps. Indicates that this device supports camera and microphone indicators. The value is `false` if present, because the [`CompatChanges#isChangeEnabled`](https://cs.android.com/android/platform/superproject/main/+/main:frameworks/base/core/java/android/app/compat/CompatChanges.java;l=58?q=isChangeEnabled) method returns `true` if the Change ID is not present. |
| ### `DOWNSCALED` **Change ID:** 168419799 **Default State** : Disabled for all apps. This change is the gatekeeper of all per-app buffer downscaling changes. Enabling this change allows the following scaling factors to be applied: - [`DOWNSCALE_30`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_30) - [`DOWNSCALE_35`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_35) - [`DOWNSCALE_40`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_40) - [`DOWNSCALE_45`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_45) - [`DOWNSCALE_50`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_50) - [`DOWNSCALE_55`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_55) - [`DOWNSCALE_60`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_60) - [`DOWNSCALE_65`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_65) - [`DOWNSCALE_70`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_70) - [`DOWNSCALE_75`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_75) - [`DOWNSCALE_80`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_80) - [`DOWNSCALE_85`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_85) - [`DOWNSCALE_90`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_90) When this change is enabled for an app package, the app is forcibly resized to the highest, enabled scaling factor. For example, 80% is used if both 80% and 70% ([`DOWNSCALE_80`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_80) and [`DOWNSCALE_70`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_70)) are enabled. When both this change and [`DOWNSCALED_INVERSE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled_inverse) are enabled, [`DOWNSCALED_INVERSE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled_inverse) takes precedence and the scaling factor is applied inversely. |
| ### `DOWNSCALED_INVERSE` **Change ID:** 273564678 **Default State** : Disabled for all apps. This change is the gatekeeper of all per-app buffer inverse downscaling changes. Enabling this change allows the following scaling factors to be inversely applied (that is, the resolution is upscaled instead): - [`DOWNSCALE_30`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_30) - [`DOWNSCALE_35`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_35) - [`DOWNSCALE_40`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_40) - [`DOWNSCALE_45`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_45) - [`DOWNSCALE_50`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_50) - [`DOWNSCALE_55`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_55) - [`DOWNSCALE_60`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_60) - [`DOWNSCALE_65`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_65) - [`DOWNSCALE_70`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_70) - [`DOWNSCALE_75`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_75) - [`DOWNSCALE_80`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_80) - [`DOWNSCALE_85`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_85) - [`DOWNSCALE_90`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_90) When this change is enabled for an app package, the app is forcibly resized to the lowest, enabled scaling factor. For example, 80% is used if both 80% and 70% ([`DOWNSCALE_80`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_80) and [`DOWNSCALE_70`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscale_70)) are enabled because when inversely applied, an 80% scaling factor equals 125%, which is less than the 142.86% scaling that is applied when inversely applying a 70% scaling factor. When both this change and [`DOWNSCALED`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled) are enabled, [`DOWNSCALED_INVERSE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled_inverse) takes precedence and the scaling factor is applied inversely. |
| ### `DOWNSCALE_30` **Change ID:** 189970040 **Default State** : Disabled for all apps.

If [`DOWNSCALED_INVERSE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled_inverse) is also enabled, enabling this change for a package forces the app to assume it's running on a display with 285.71% of the vertical and horizontal resolution of the real display. |
| ### `DOWNSCALE_40` **Change ID:** 189970038 **Default State** : Disabled for all apps. If [`DOWNSCALED`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled) is also enabled, enabling this change for a package forces the app to assume it's running on a display with 40% of the vertical and horizontal resolution of the real display. If [`DOWNSCALED_INVERSE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#downscaled_inverse) is also enabled, enabling this change for a package forces the app to assume it's running on a display with 250% of the vertical and horizontal resolution of the real display. |
| ### `DOWNSCALE_45` **Change ID:** 189969782 **Default State** : Disabled for all apps.

| ### `FORCE_DISABLE_HEVC_SUPPORT` **Change ID:** 174227820 **Default State** : Disabled for all apps. Force disable an app from supporting the HEVC media capability. Apps should declare their supported media capabilities in their manifest but this flag can be used to force an app into not supporting HEVC, hence forcing transcoding while accessing media encoded in HEVC. Setting this flag overrides any OS level defaults for apps. It is disabled by default, meaning that the OS defaults take precedence. If both this flag and `FORCE_ENABLE_HEVC_SUPPORT` are enabled, the OS ignores both flags. |
| ### `FORCE_ENABLE_HEVC_SUPPORT` **Change ID:** 174228127 **Default State** : Disabled for all apps. Force enable an app to support the HEVC media capability Apps should declare their supported media capabilities in their manifest but this flag can be used to force an app into supporting HEVC, hence avoiding transcoding while accessing media encoded in HEVC. Setting this flag overrides any OS level defaults for apps. It is disabled by default, meaning that the OS defaults would take precedence. If both this flag and `FORCE_DISABLE_HEVC_SUPPORT` are enabled, the OS ignores both flags. |
| ### `FORCE_NON_RESIZE_APP` **Change ID:** 181146395 **Default State** : Disabled for all apps. Forces the packages it is applied to to be non-resizable. |
| ### `FORCE_RESIZE_APP` **Change ID:** 174042936 **Default State** : Disabled for all apps. Forces the packages it is applied to to be resizable. We only allow resizing in fullscreen windowing mode, but not forcing the app into resizable multi-windowing mode. |
| ### `GWP_ASAN` **Change ID:** 145634846 **Default State** : Disabled for all apps. Enables sampled native memory bug detection in apps. To learn more about using GWP-ASan, see the [GWP-ASan guide](https://developer.android.com/ndk/guides/gwp-asan). |
| ### `NATIVE_HEAP_ZERO_INIT` **Change ID:** 178038272 **Default State** : Disabled for all apps. Enable automatic zero-initialization of native heap memory allocations. |
| ### `NATIVE_MEMTAG_ASYNC` **Change ID:** 145772972 **Default State** : Disabled for all apps. Enable asynchronous (ASYNC) memory tag checking in this process. This flag only affects hardware supporting the ARM Memory Tagging Extension (MTE). |
| ### `NATIVE_MEMTAG_SYNC` **Change ID:** 177438394 **Default State** : Disabled for all apps. Enables synchronous (SYNC) memory tag checking in this process.

| ### `OVERRIDE_ANY_ORIENTATION` **Change ID:** 265464455 **Default State** : Disabled for all apps. When enabled, this change allows the following orientation overrides to be applied regardless of the orientation requested by the activity: - [`OVERRIDE_LANDSCAPE_ORIENTATION_TO_REVERSE_LANDSCAPE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_landscape_orientation_to_reverse_landscape) - [`OVERRIDE_UNDEFINED_ORIENTATION_TO_NOSENSOR`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_undefined_orientation_to_nosensor) - [`OVERRIDE_UNDEFINED_ORIENTATION_TO_PORTRAIT`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_undefined_orientation_to_portrait) |
| ### `OVERRIDE_ANY_ORIENTATION_TO_USER` **Change ID:** 310816437 **Default State** : Disabled for all apps. When enabled, enables [`SCREEN_ORIENTATION_USER`](https://developer.android.com/reference/android/content/pm/ActivityInfo#SCREEN_ORIENTATION_USER), which overrides any orientation requested by the activity. Fixed orientation apps can be overridden to fullscreen on large screen devices with `ignoreOrientationRequest` enabled with this override. |
| ### `OVERRIDE_CAMERA_COMPAT_DISABLE_FREEFORM_WINDOWING_TREATMENT` **Change ID:** 314961188 **Default State** : Disabled for all apps. When enabled, excludes the packages the override is applied to from the camera compatibility treatment in free-form windowing mode for fixed-orientation apps. In free-form windowing mode, the compatibility treatment emulates running on a portrait device by letterboxing the app window and changing the camera characteristics to what apps commonly expect in a portrait device: 90 and 270 degree sensor rotation for back and front cameras, respectively, and setting display rotation to 0. Use this flag to disable the compatibility treatment for apps that don't respond well to the treatment. |
| ### `OVERRIDE_CAMERA_RESIZABLE_AND_SDK_CHECK` **Change ID:** 191514214 **Default State** : Disabled for all apps. When enabled, this change forces the packages it is applied to ignore the current value of `android:resizeableActivity` as well as target SDK equal to or lower than Android 6.0 (API level 23) and consider the activity as non-resizable. In this case, the value of camera rotate and crop only depends on the needed compensation considering the current display rotation. |
| ### `OVERRIDE_CAMERA_ROTATE_AND_CROP_DEFAULTS` **Change ID:** 189229956 **Default State** : Disabled for all apps. When enabled, this change forces the packages it is applied to override the default camera rotate and crop behavior and always return `CaptureRequest.SCALER_ROTATE_AND_CROP_NONE`. |
| ### `OVERRIDE_DISABLE_MEDIA_PROJECTION_SINGLE_APP_OPTION` **Change ID:** 316897322 **Default State** : Disabled for all apps. When enabled, ensures that users are presented with a choice of capturing a single app or the entire screen when initiating a `MediaProjection` session, overriding the usage of [`MediaProjectionConfig#createConfigForDefaultDisplay`](https://developer.android.com/reference/android/media/projection/MediaProjectionConfig#createConfigForDefaultDisplay()). |
| ### `OVERRIDE_LANDSCAPE_ORIENTATION_TO_REVERSE_LANDSCAPE` **Change ID:** 266124927 **Default State** : Disabled for all apps. Enables [`SCREEN_ORIENTATION_REVERSE_LANDSCAPE`](https://developer.android.com/reference/android/content/pm/ActivityInfo#SCREEN_ORIENTATION_REVERSE_LANDSCAPE) for the app it's applied to. Unless [`OVERRIDE_ANY_ORIENTATION`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_any_orientation) is also enabled, `SCREEN_ORIENTATION_REVERSE_LANDSCAPE` is used only when the activity specifies landscape orientation. Enabling this change can help you test your app behavior for differences between devices where landscape orientation corresponds to [`Surface.ROTATION_90`](https://developer.android.com/reference/android/view/Surface#ROTATION_90) and devices where it corresponds to [`Surface.ROTATION_270`](https://developer.android.com/reference/android/view/Surface#ROTATION_270). |
| ### `OVERRIDE_LAYOUT_IN_DISPLAY_CUTOUT_MODE` **Change ID:** 332679525 **Default State** : Disabled for all apps. When enabled, overrides the layout in display cutout mode behavior. This will only apply if edge-to-edge is not enforced. |
| ### `OVERRIDE_MIN_ASPECT_RATIO` **Change ID:** 174042980 **Default State** : Disabled for all apps. This change is the gatekeeper of all changes that force a given minimum aspect ratio. Enabling this change allows the following minimum aspect ratios to be applied: - [`OVERRIDE_MIN_ASPECT_RATIO_LARGE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio_large) - [`OVERRIDE_MIN_ASPECT_RATIO_MEDIUM`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio_medium) - [`OVERRIDE_MIN_ASPECT_RATIO_PORTRAIT_ONLY`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio_portrait_only) When this change is enabled for an app package, the minimum aspect ratio given in the app's manifest is overridden to the largest enabled aspect ratio unless the app's manifest value is higher. |
| ### `OVERRIDE_MIN_ASPECT_RATIO_EXCLUDE_PORTRAIT_FULLSCREEN` **Change ID:** 218959984 **Default State** : Disabled for all apps. When enabled, overrides the minimum aspect ratio restriction in portrait fullscreen in order to use all available screen space. |
| ### `OVERRIDE_MIN_ASPECT_RATIO_LARGE` **Change ID:** 180326787 **Default State** : Disabled for all apps. When [`OVERRIDE_MIN_ASPECT_RATIO`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio) is also enabled, enabling this change for a package sets the activity's minimum aspect ratio to a large value as defined by `OVERRIDE_MIN_ASPECT_RATIO_LARGE_VALUE`. |
| ### `OVERRIDE_MIN_ASPECT_RATIO_MEDIUM` **Change ID:** 180326845 **Default State** : Disabled for all apps. When [`OVERRIDE_MIN_ASPECT_RATIO`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio) is also enabled, enabling this change for a package sets the activity's minimum aspect ratio to a medium value as defined by `OVERRIDE_MIN_ASPECT_RATIO_MEDIUM_VALUE`. |
| ### `OVERRIDE_MIN_ASPECT_RATIO_ONLY_FOR_CAMERA` **Change ID:** 325586858 **Default State** : Disabled for all apps. When enabled, restricts treatments that force a given min aspect ratio to apply so that they only apply when an app is connected to the camera. |
| ### `OVERRIDE_MIN_ASPECT_RATIO_PORTRAIT_ONLY` **Change ID:** 203647190 **Default State** : Enabled for all apps. When [`OVERRIDE_MIN_ASPECT_RATIO`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio) is also enabled, this change limits any other changes that force an activity's minimum aspect ratio to a certain value---such as [`OVERRIDE_MIN_ASPECT_RATIO_LARGE`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio_large) and [`OVERRIDE_MIN_ASPECT_RATIO_MEDIUM`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_min_aspect_ratio_medium)---to activities that also have a portrait orientation. |
| ### `OVERRIDE_RESPECT_REQUESTED_ORIENTATION` **Change ID:** 236283604 **Default State** : Disabled for all apps. When enabled, this change excludes packages that is applied to from the ignore orientation restrictions that device manufacturers can set. |
| ### `OVERRIDE_UNDEFINED_ORIENTATION_TO_NOSENSOR` **Change ID:** 265451093 **Default State** : Disabled for all apps. Enables [`SCREEN_ORIENTATION_NOSENSOR`](https://developer.android.com/reference/android/content/pm/ActivityInfo#SCREEN_ORIENTATION_NOSENSOR) for the app it's applied to. Unless [`OVERRIDE_ANY_ORIENTATION`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_any_orientation) is also enabled, `SCREEN_ORIENTATION_NOSENSOR` is used only when the activity doesn't specify any other fixed orientation. |
| ### `OVERRIDE_UNDEFINED_ORIENTATION_TO_PORTRAIT` **Change ID:** 265452344 **Default State** : Disabled for all apps. Enables [`SCREEN_ORIENTATION_PORTRAIT`](https://developer.android.com/reference/android/content/pm/ActivityInfo#SCREEN_ORIENTATION_PORTRAIT) for the app it's applied to. Unless [`OVERRIDE_ANY_ORIENTATION`](https://developer.android.com/about/versions/16/reference/compat-framework-changes#override_any_orientation) is also enabled, `SCREEN_ORIENTATION_PORTRAIT` is used only when the activity doesn't specify any other fixed orientation. |
| ### `RATE_LIMIT_TOASTS` **Change ID:** 174840628 **Default State** : This change can't be toggled. It is only logged by the compatibility framework. Enables rate limiting on the number of [`Toast.show()`](https://developer.android.com/reference/android/widget/Toast#show()) calls to prevent overburdening the user with too many toasts in a limited time. Any attempt to show more toasts than allowed in a certain timeframe results in the toast being discarded. |
| ### `STPE_SKIP_MULTIPLE_MISSED_PERIODIC_TASKS` **Change ID:** 288912692 **Default State** : Enabled for apps that target Android 16 (API level 36) or higher.
