我正在我的一项活动中创建闹钟管理员，例如关注
AlarmManager alarmManager=(AlarmManager) MenuItems.this.getSystemService(Context.ALARM_SERVICE);
Intent intent23 = new Intent(MenuItems.this, MyReceiver.class);
PendingIntent pendingIntent23 = PendingIntent.getBroadcast(MenuItems.this, 0, intent, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(),300000,
pendingIntent);
此后我跟随BroadcastReceiver
public class MyReceiver extends WakefulBroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(),
MyAlarmService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
此广播接收器呼叫我的以下服务

{
private String server_response,data_to_send;
private String server ;
private String setLocation = "/xyz";

一切正常，我的活动设置了Alarmmanager，每隔5分钟触发一次广播接收器即使我的应用程序关闭且电话未被使用我也会在我的服务器上获得用户位置，但是在某些手机上执行我的服务喜欢galaxy NoteEdge这段代码不起作用。我做错了什么，每隔5分钟就没有得到用户位置。如果这不是正确的做法，请建议任何相关的方法。
