我从 google play 获得了下面的堆栈，但我不明白为什么：

来自 PlayerCardsEventsListner.select 的来源：

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);
}

声音管理器：声音管理器

首先，select(Card card)在哪里调用？. 这对于避免主 UI 线程中的日志操作（在活动中执行的标准操作，例如 onCreate()）非常重要。如果你不小心运行了一些循环，或者死锁发生的 UI 将冻结并且 ANR 会被注意到。尝试使用 AsyncTask 播放声音并检查方法执行的时间。请记住，较慢的设备需要更多时间来执行操作。好的，现在看看它在哪里被调用。
