Question

i get the stack below from google play, but i’m not understand why:

Source from PlayerCardsEventsListner.select:

void select(Card card) {
    card.select(!card.isSelected());
    if (card.isSelected()) card.setPosition(card.getPosition().x, card.getPosition().y-10);
    else card.setPosition(card.getPosition().x, card.getPosition().y+10);           
    SoundManager.playSound(SoundManager.SOUND_DROP, 1);
}

SoundManager: SoundManager

Answer 1

First of all, where is select(Card card) called?. This is very important to avoid log operations in main UI thread (standard actions performed in activity e.g. onCreate()).
If you accidentally run some loop, or deadlock happend UI will freeze and ANR will be noticed.
Try to use AsyncTask to play the sound and check the time of method execution. Remember that the slower devices needs more time to perform operations.
Ok, now is see where it is called.
