| private static native void | dtor(long ptr)

| boolean | isKeyInList(java.lang.String key, java.lang.String[] list)

| static void | performBackup_checked(android.os.ParcelFileDescriptor oldState, BackupDataOutput data, android.os.ParcelFileDescriptor newState, java.lang.String[] files, java.lang.String[] keys)Check the parameters so the native code doesn't have to throw all the exceptions
since it's easier to do that from Java.
