我正在使用廣播接收器讀取Intent.ACTION_TIME_TICK並使其每分鐘播放一次服務音頻。一切正常,除非屏幕關閉,它不再發出聲音。如果我保持屏幕打開或者在屏幕關閉的情況下插入USB電纜,它將重新打開。請幫忙,謝謝!Android廣播接收器在屏幕關閉後不會觸發
PS。經過幾次測試,我發現這隻發生在我的android 2.3.6手機上,另一方面在我的4.1.2上,它運行沒有問題。
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
mgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
registerReceiver(new TickReceiver(), new IntentFilter(
Intent.ACTION_TIME_TICK));
mp = MediaPlayer.create(this, R.raw.cuckoo);
}
@Override
public void onStart(Intent intent, int startId) {
notifyMe();
}
@Override
public void onDestroy() {
clearNotification();
if (mp != null){
mp.release();
mp = null;
}
}
public void notifyMe() {
note = new Notification(R.drawable.front, "Message Inbound!",
System.currentTimeMillis());
PendingIntent i = PendingIntent.getActivity(this, 0, new Intent(this,
LeftAndRightActivity.class), Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);
note.setLatestEventInfo(this, "Title...", "Subtitle", i);
note.flags = note.flags | Notification.FLAG_ONGOING_EVENT;
mgr.notify(NOTIFY_ME_ID, note);
}
public void clearNotification() {
mgr.cancel(NOTIFY_ME_ID);
}
public void playBeep() {
mp.start();
}
public class TickReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
playBeep();
}
}
