System enforces cached-app resource usage In Android 14 and higher, the platform reduces the maximum memory that can be locked using mlock() to 64 KB per process. New reason an app can be placed in the restricted standby bucketĪndroid 14 introduces a new reason an app can be placed into the restricted standby bucket. The Android Bluetooth stack more strictly adheres to Version 5.2 of the Bluetooth Core Specification and requests the BLE ATT MTU to 517 bytes when the first GATT client requests an MTU using the BluetoothGatt#requestMtu(int) API, and disregards all subsequent MTU requests on that ACL connection. MTU is set to 517 for the first GATT client requesting an MTU When your app calls killBackgroundProcesses(), the API can kill only the background processes of your own app. The system may place context-registered broadcasts in a queue when these broadcasts are queued for delivery to an app that's in the cached state.Īpps can kill only their own background processes The SCHEDULE_EXACT_ALARM permission is no longer being pre-granted to most newly-installed apps targeting Android 13 and higher-the permission is denied by default.Ĭontext-registered broadcasts are queued while apps are cached Schedule exact alarms are denied by default Implement request override controls to give users zoom control even before other camera controls are ready.Īndroid 14 gains support for lossless audio formats for audiophile-level experiences over USB wired headsets. Zoom, Focus, Postview, and more in camera extensionsĪndroid 14 upgrades and improves camera extensions, allowing apps to handle longer processing times, which enables improved images using compute-intensive algorithms like low-light photography on supported devices. Test your app with non-linear font scalingīecause Android supports font scaling up to 200%, you should perform UI testing to ensure that your app can accommodate larger font sizes without impacting usability.Īndroid supports font scaling up to 200%, providing low-vision users with additional accessibility options that align with Web Content Accessibility Guidelines (WCAG).Īndroid 14 adds support for High Dynamic Range (HDR) images that retain more of the information from the sensor when taking a photo, which enables vibrant colors and greater contrast.
