1、需要 IRotationWatcher.aidl

// IRotationWatcher.aidl
package android.view;

// Declare any non-default types here with import statements

interface IRotationWatcher {
 void onRotationChanged(int rotation);
}

2、需要 IWindowManager.aidl

public interface IWindowManager {

    @RequiresApi(26)
    int watchRotation(IRotationWatcher watcher, int displayId);

    @RequiresApi(26)
    int getDefaultDisplayRotation();
}
