另一個ANR keyDispatchingTimedOut錯誤。但我想不出爲什麼

Question

我從谷歌播放下的堆棧，但我不明白爲什麼：從PlayerCardsEventsListner.select

來源：

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); 
} 

SoundManager類：SoundManager

Answer 1

首先，select（card card）在哪裏被調用？ 。這對避免主UI線程中的日誌操作非常重要（例如在onCreate（））等活動中執行的標準操作。 如果你不小心運行了一些循環，或者發生了死鎖，那麼UI將會凍結並且ANR會被注意到。 嘗試使用AsyncTask播放聲音並檢查方法執行的時間。請記住，較慢的設備需要更多時間來執行操作。好吧，現在看看它在哪裏被調用。
