30 분마다 일부 작업을 실행하는 네이티브 android 앱을 개발 중입니다. 프로세서가 실행 중인지 확인해야하므로 알람 수신기에AlaramManager와 PowerManager.WakeLock을 사용할 때의 예외 권한 android
PowerManager.Wakelock을 사용했습니다.
여기 내 경보 수신기에 사용하고있는 코드입니다.
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
PowerManager pm = (PowerManager) context.getSystemService(context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
wl.acquire();
Intent eventService = new Intent(context, SyncInBackground.class);
context.startService(eventService);
wl.release();
}
}
내 주요의 AndroidManifest.xml에서
는 나는 내가 다음과 같은 예외를 가지고 내 응용 프로그램에서 알람을 실행하면 권한<uses-permission android:name="android.permission.wake_lock"/>
