Android 10 and better help Modular System Elements that permit us to expedite purposeful and safety updates to the Android ecosystem exterior of main API stage releases and make new performance backward suitable on already-released Android variations. These enhancements assist make growth extra versatile and broaden the attain for app builders. We have constructed a brand new Extension SDK framework so that you can combine with these APIs, and right now, we’re releasing the primary public model of the Extension SDK (Extension Degree 4).
Sooner API and have introductions
Being able to introduce new performance exterior of main API stage releases permits sooner improvements. As shared in a earlier publish, starting this 12 months we plan to roll out the preliminary Privateness Sandbox on Android Beta launch to Android 13 units. You can begin utilizing the Extension SDK to combine your options with the AdServices APIs to arrange for restricted manufacturing testing. Be taught extra on learn how to take part within the Privateness Sandbox Beta launch, and arrange your growth surroundings with a take a look at gadget or emulator.

Verify for API availability

enjoyable isPhotoPickerAvailable(): Boolean { |
The choice test, through Construct.VERSION.SDK_INT, would appear like this:
enjoyable isPhotoPickerAvailable(): Boolean { |
This test remains to be secure and proper, however this operate would return false on some units the place the API is now accessible. Because of this, the SDK_INT test just isn’t optimum, and the extension model test is a greater technique to test for API availability. All units with SDK_INT >= 33 additionally have an R extension model of >= 2, however there are units with SDK_INT < 33 with R extension variations >= 2.
Equally, the AdServices API reference might point out that it’s “added in Advert Companies Extensions 4”. The Advert Companies extension makes use of the SdkExtensions.AD_SERVICES fixed. The provision test seems like this:
enjoyable isAdServicesAvailable(): Boolean { |
For developer comfort, we’re extending Jetpack to make it simpler to work with extension variations. For instance, you need to use a Jetpack library operate to test for PhotoPicker availability, which abstracts away the conditional model checks. We count on to be releasing extra Jetpack libraries (such because the Privateness Preserving APIs within the Privateness Sandbox) to help the right use of APIs launched through Extension SDKs.
Tooling help
To assist guarantee app high quality, we added Extension variations tooling help to Android Lint’s NewApi test. Since Android Studio Flamingo, it will probably auto-generate the right model checks for APIs which have been launched through SDK extensions. Utilizing these new model checks is totally non-obligatory, however adopting them may assist result in extra widespread use of recent APIs after they exist.

Get familiarized with SDK extensions
We’re simply starting the SDK Extension developer journey and plan to make extra options accessible sooner or later. You may get the most recent SDK extension 4 accessible within the SDK Supervisor right now. Be taught extra in regards to the SDK Extensions and our documentation on the Privateness Sandbox Beta and the picture picker.
