Youtube application when moving to PIP animation was very bad

Problem: {
    1. Start any new task with activity A
    2. From Activity A start new activity B. Finish A. B must be single task.
    3. B must be auto pip enabled. ( private final PictureInPictureParams.Builder mPipParamsBuilder = new PictureInPictureParams.Builder() .setAspectRatio(null); setPictureInPictureParams(mPipParamsBuilder.setAutoEnterEnabled(true).build()); )
    4. start activity C from B with flags { Intent intent = new Intent(MainActivity.this, com.example.pip.MainActivity.class); intent.addFlags(FLAG_ACTIVITY_BROUGHT_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK | FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS|FLAG_ACTIVITY_PREVIOUS_IS_TOP); startActivity(intent); }
    5. B will move to PIP.
    6. Now press back key on C.
    7. Now open recents.
    8. Try to open same app.
    9. App will automatically close
}

Solution: {
        1. there are 2 tasks. One is PIP task and one is its parent task, in which dialog is opened.
        2. Parent task has a variable mPipChildActiivty which points to PIP activity and
        3. PIP task mLastParentBeforePip which points to Parent task. Both works in pairs
        4. But in this issue parent task is removed.
        5. But the mPipChildActiivty and mLastParentBeforePip are not dereferenced.
        6. Dereference the both variables when task is removed.
}
