Question

My build.gradle has a single warning regarding the line:

targetSdkVersion 34

and the warning reads:

Not targeting the latest versions of Android;
 compatibility modes apply.
 Consider testing and updating this version.
 Consult the `android.os.Build.VERSION_CODES` javadoc for details.

The warning also suggests a clickable text:

Launch Android SDK Upgrade Assistant

but when I click it, the Assistant pops up, empty, containing only a message that spins forever:

Loading assistant content

How do I make the Android SDK Upgrade Assistant on Android Studio work?

Answer 1

Due to a bug in your version of Android Studio, you can't currently make the Android SDK Upgrade Assistant on Android Studio work.

Instead, use the Android Studio feature that lets you override this error. But... only do that if you know what you're doing!

Key Areas to Consider:

• Foreground Services: Android 15 introduces new restrictions on foreground services, particularly for data sync and media processing, with a 6-hour limit within 24 hours. See specific mentions of timeout behaviors and exceptions like ForegroundServiceStartNotAllowedException.

• Do Not Disturb Mode: Apps cannot directly modify the global DND state, requiring AutomaticZenRule, which aligns with privacy and user control enhancements.

• OpenJDK API Changes: Several updates were noted, including stricter string formatting, changes in Arrays.asList().toArray() behavior, locale code updates, and potential Kotlin conflicts with SequencedCollection. These are critical for apps using Java or Kotlin, as they may cause runtime errors.

• Security and Background Tasks: TLS 1.0 and 1.1 deprecation, stricter background activity launches, and safer intent handling.

• UI and Text Handling: Edge-to-edge display enforcement, changes in window insets, and new TextView/EditText behaviors, which could impact UI layouts, especially for complex scripts.

• Audio and Other Changes: Audio focus restrictions and non-SDK interface updates, affecting background audio apps and apps using restricted interfaces.
