- File integrity.
FileIntegrityManagergains APIs built on the kernel’s fs-verity, so an app can protect files with its own cryptographic signatures and detect tampering. - Partial screen sharing. Sharing or recording a single app window, first
enabled in Android 14 QPR2, gets
MediaProjectioncallbacks. Each capture session now needs the user’s consent. - Camera. Extensions for low-light preview brightening and for flash
strength in
SINGLEandTORCHmodes, on supported devices. - Virtual MIDI 2.0. Universal MIDI Packets, supported over USB since Android 13, extend to virtual MIDI apps, so a composition app can drive a synthesizer app.
- ADPF. Hint sessions get a power-efficiency mode and can report GPU work duration next to CPU work; thermal headroom thresholds help predict throttling.
- Updatable modules. Ad Services moves to extension level 10 with the latest Privacy Sandbox, Health Connect adds fitness and nutrition data types, and new OpenJDK APIs reach Android 12 and later through Google Play system updates.
Google advised testers on the Android 14 QPR beta to move to Preview 1 right away, because a later QPR build date would otherwise force a data wipe.
