Question

我正在尝试使用带有AlarmManager的IntentService来安排警报。我使用BroadCast Reciever进一步调用我的IntentService这里是代码：

设置闹钟：

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;
}

这是我的BroadCast Reciever课程：

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);
    }
}

最后我有下面的IntentService类，我也得到了用户的当前位置：

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Manifest中，我已将注册人和服务注册为：

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

但现在当闹钟在设定的时间触发时，它无法到达BroadCast接收器的 onReceive 处的断点。我得到了IntentService的错误。这是错误日志：

Answer 1

尝试向您的服务添加另一个构造函数，该构造函数接受String param＆＃39; name＆＃39;并将其传递给super

的构造函数

Answer 2

问题出在 IntentService 中的 onConnected 方法中。 OnConnected方法中存在一些导致IntentService无法触发的运行时错误。

newInstance调用中的类init失败：对于从alarmManager调用的IntentService
