1. Predictive Back Gesture in action
Already in Android 13, we were warned that in the next version of Android, we should expect updates of the Back Gesture and Predictive Back Gesture with animation in the form of a preview screen where we will move. Animation for that preview is still not working. If you want it to work, you should activate it in the developer’s settings.
Also, the ability to create personal transition animations inside the application was added. For that, a method handleOnBackProgressed() was added in OnBackPressedCallback. This method is called with the progress of the Back Gesture, as well as the handleOnBackPressed() and handleOnBackCancelled() methods, which are called at the end of the Back Gesture’s animation and its cancellation, respectively. On the screen, you can see an example of implementing your custom animation using the Jetpack AppCompat 1.8.0 library.
