在newInstance調用中類初始化失敗：對於從alarmManager調用的IntentService

Question

我正在嘗試將IntentService與AlarmManager一起使用以安排警報。 我使用了BroadCast Reciever，它在下面的代碼中進一步調用了我的IntentService：

設置警報：

public static Integer createScheduledAlarm(Calendar calendar,
        int intervalSeconds, Context context) {

    AlarmManager alarmManager = (AlarmManager) context
            .getSystemService(Context.ALARM_SERVICE);

    int id = (int) System.currentTimeMillis();

    Intent intent = new Intent(context,
            com.stressfree.alerts.TimeAlarm.class);


    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, id,
            intent, PendingIntent.FLAG_UPDATE_CURRENT);

    if (intervalSeconds > 0) {
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                calendar.getTimeInMillis(), intervalSeconds * 1000,
                pendingIntent);
    }   
    return id;
}

這是我的BroadCast接收器課程：

public class TimeAlarm extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    //Bundle bundle = intent.getExtras();
    Intent taskService = new Intent(context, TaskService.class);
    //taskService.putExtras(bundle);
    context.startService(taskService);
    }
}

最后，我在下面的IntentService類中獲取了用戶的當前位置：

public class TaskService extends IntentService implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener{


public TaskService() {
    super("TaskService");
}

private LocationClient locationclient;
private Location mCurrentLocation;
private Context mContext;



@Override
protected void onHandleIntent(Intent intent) {

    Log.e("Service", "Inside onHandleIntent");
    mContext = this;
    int resp = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (resp == ConnectionResult.SUCCESS) {
        locationclient = new LocationClient(this, this, this);
        locationclient.connect();
    }

}
@Override
public void onConnectionFailed(ConnectionResult arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onConnected(Bundle arg0) {
    mCurrentLocation = locationclient.getLastLocation();
    //Do some stuff
}

@Override
public void onDisconnected() {
    // TODO Auto-generated method stub

}

在清單中，我已將接收者和服務注冊為：

        <receiver android:name=".TimeAlarm" />
        <service android:name=".services.TaskService" >

但是現在，當警報在設定的時間觸發時，它並​​沒有到達BroadCast接收器的onReceive的斷點。 而且我收到IntentService錯誤。 這是錯誤日志：

Answer 1

嘗試向您的服務中添加另一個接受String參數'name'的構造函數，並將其傳遞給super的構造函數

Answer 2

問題出在我的IntentService內部的onConnected方法中。 OnConnected方法中存在一些運行時錯誤，導致IntentService無法啟動。
