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）..
我正在从 BroadcastReceiver 调用 AlarmManager 类，并且我已经为 BOOT_COMPLETE 事件注册了 BroadcastReceiver(BroadcastReceiverImpl 类)...它在 android 模拟器中正常工作，但在 Android 设备中不工作(我已经在 Samsung Galaxy 中检查过) s2 和三星 Galaxy Tab）这里是源代码..
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");
}
}

请告诉我是什么错误...请让我知道我在哪里可以找到 Android 设备中的日志文件...（因为它在 Android 模拟器上运行但没有在 Android 设备上运行 i=...）谢谢提前
