We should also avoid using non-static inner class that extends IOnBackInvokedCallback.Stub and IRemoteAnimationRunner.Stub inside LauncherBackAnimationController, which references the entire LauncherBackAnimationController object. 1. When launcher is created, a Runnable is posted to ShellExecutor to call BackAnimationController#registerAnimation 2. When launcher is later destroyed, another Runnable is posted to same ShellExecturo to call BackAnimationController#unregisterAnimation 3. If the execturo queued the 1st runnable, then we have leaked LauncherBackAnimationController object, including Launcher activity. This CL fixes the leak by making the Stub static inner classes, and use weak reference hold reference to launcher activity.
