Android 16 QPR2 Beta 1 is here ✨ The first beta of Android 16 QPR2 is now available, the inaugural Android release with an Android minor SDK version. Minor SDK versions can include new APIs that extend platform features but cannot introduce targetSdkVersion gated behavior changes, minimizing the amount you need to test your apps against it. You can call new APIs by checking SDK_INT_FULL against the VERSION_CODES_FULL enumeration: if (Build.VERSION.SDK_INT_FULL >= Build.VERSION_CODES_FULL.BAKLAVA_1) { // Call new APIs from the Android 16 QPR2 release } VERSION_CODES_FULL cannot be used in uses-sdk manifest attributes. Here are some key updates from QPR2 Beta 1. UI, System Experience, and Accessibility: An expanded dark theme option intelligently inverts light apps for users preferring a dark appearance. Auto-themed app icons can be generated by the system if your app doesn't provide a monochrome layer. Interactive chooser sessions keep your app UI active while the sharesheet is open, using ChooserManager and ChooserSession. A new Data Transfer API enables more reliable and secure data migration between Android and iOS, requiring updates to your app's data extraction rules XML and BackupAgent implementation. The android.graphics.pdf package has expanded to support annotating and editing PDF documents via PdfRenderer.Page.
