Android应用。在模拟器中工作，但在Android设备中不起作用

Question

我编写了一个简单的应用程序来获取网络详细信息，我使用AlarmManager在后台连续运行一段代码（IntentServiceImpl类）。

我从BroadcastReceiver调用AlarmManager类，我已经为BOOT_COMPLETE事件注册了BroadcastReceiver（BroadcastReceiverImpl类）...它在Android模拟器中正常工作但是它在Android设备中不起作用（我已经检查过了）在三星Galaxy s2和三星Galaxy Tab）这是源代码..

BroadcastReceiverImpl.java

public class BroadcastReceiverImpl extends BroadcastReceiver {

    private static final String LOG_TAG = BroadcastReceiverImpl.class.getSimpleName();

    @Override
    public void onReceive(Context context, Intent intent) {


        Log.d(LOG_TAG, "Inside the BroadcastReceiver Class");

        Calendar calendar = Calendar.getInstance();
        calendar.add(Calendar.SECOND,QOSConstants.TIME_DELAY_IN_SECONDS);

        Intent serviceIntent = new Intent(context, IntentServiceImpl.class);
        serviceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);


        PendingIntent pendingIntent = PendingIntent.getService(context, QOSConstants.REQUEST_CODE,serviceIntent, PendingIntent.FLAG_CANCEL_CURRENT);


        AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        //After after 60 seconds
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 
        QOSConstants.MILLISECONDS * QOSConstants.TIME_DELAY_IN_SECONDS, pendingIntent); 

        Log.d(LOG_TAG, "Exiting the QOSBroadcastReceiver Class");
    }
}

IntentServiceImpl.java

public class IntentServiceImpl extends IntentService implements LocationListener {

    private String strNetworkInfo;
    private LocationManager locationManager;

请告诉我们错误是什么...请告诉我在哪里可以找到Android设备中的日志文件...（因为它在Android模拟器上运行但在Android设备上没有运行i = 。）提前致谢
