搜索我發現，有些手機（如Galaxy S的）是由一個奇怪的錯誤或什麼導致此錯誤的影響後：

這是logcat的如果需要的話，從這裏看來，是刷卡功能的問題：

，可能會導致此錯誤的唯一的事情就是我在遊戲中的意圖應用程序中使用定時器，我試圖建立一個處理程序，但我看到了很多崩潰在我的ACRA日誌中。
這是我的意圖的內容，我希望有人應該幫助我:)
startB.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
startB.setEnabled(false);
partiColTempo(tempox);
}
});
}
private void displayText(final String text){
this.runOnUiThread(new Runnable(){
//@Override
public void run() {
tempo.setText(text);
if (text.equals("Finished")){
eseguiSuono();
assegnaPunti();
startB.setEnabled(true);
//elapsed=0;
tempo.setText("Waiting");
}
}});
}
private void partiColTempo(int tempox) {
TIMEOUT=tempox*1000;
Log.w("tempo timer", ""+tempox);
elapsed=INTERVAL;
TimerTask task=new TimerTask(){
@Override
public void run() {
elapsed+=INTERVAL;
if(elapsed>TIMEOUT){
this.cancel();
displayText("Finished");
return;
}
//if(some other conditions)
// this.cancel();
displayText(getString(R.string.tempo_rim)+" " + (TIMEOUT-elapsed)/1000);
}
};
Timer timer = new Timer();
timer.scheduleAtFixedRate(task, INTERVAL, INTERVAL);
是問題嗎？因爲當我打電話給asynctask時，我找不到其他地方。
從你的logcat文章看來，這個問題是在AsyncTask中的某個地方 - 你是否正在使用這樣的一個，如果可以的話，你能否也發佈代碼？ – kaspermoerch
從logcat看來，你使主線程外部的某些視圖無效，而這在Android中是不允許的。 – Huang
所以這不是定時器的問題？我必須搜索一個AsyncTask？我的應用程序中使用的唯一「任務」是該計時器。 – Toleno
