This is a standard instructive message from Android Studio once you update the targetSdkVersion. It's meant to remind that with each new API level, there might be changes to system behaviors, permissions, or deprecated APIs that could possibly affect your app.

When you alter targetSdkVersion to 35, Android Studio prompts you to review the Behavior Changes introduced in API 35 (Android 14). It’s not necessarily pointing to any issue with your code; rather, it’s a precautionary message encouraging you to verify that your app is compatible with the new behaviors.
