Android 17 continues our work towards more adaptable Android apps, introduces significant camera and media enhancements, introduces new tools for optimizing connectivity, and expands companion device profiles.

First, in terms of UI and windows, adaptability to large screens will be mandatory, and apps running on screens wider than 600dp (approximately the width of a 7-inch device held vertically) will no longer be able to opt out of resizing or orientation changes. Additionally, by default, the system will no longer restart activities in response to configuration changes such as CONFIG_KEYBOARD / CONFIG_KEYBOARD_HIDDEN , CONFIG_NAVIGATION , and CONFIG_TOUCHSCREEN .

In terms of performance and runtime, the new lock-free implementation of ' android.os.MessageQueue ' reduces dropped frames.

Additionally, to reduce memory usage, strict size limits are applied to custom notification views .

Additionally, the cleartext attribute ' android:usesCleartextTraffic ' has been deprecated, and apps targeting SDK 37 or later that rely on this attribute will block cleartext by default.
