我的服务类别:

public class GPSService extends Service implements LocationListener {


SharedPreferences sp;
Utils util;
LocationManager locationManager;
DataBaseHelper db;

long driveId;

//empty constructor.
public GPSService() {
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    util = new Utils();

    sp = getSharedPreferences(util.APP_DATA, 0);

    locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    db = new DataBaseHelper(this);

    boolean driving = sp.getBoolean(util.DRIVING, false);

    if (intent != null) {
        if (intent.getAction() == util.STOP_DRIVE) {
            if (driving)
                stopDrive();
        } else if (intent.getAction() == util.START_DRIVE) {
            if (!driving)
                startDrive();
        }
    }

    return START_REDELIVER_INTENT;
}

我正在从片段内部调用启动服务.这是我开始服务的地方.

I am calling the starting the service from inside a fragment. here is where I am starting the service.

private void startDrive()
{
    Log.w("rakshak", "Start drive clicked");

    Intent intent = new Intent(getActivity(), GPSService.class);
    intent.setAction(util.START_DRIVE);
    getActivity().startActivity(intent);
}

private void stopDrive()
{
    Log.w("rakshak","Stop Drive clicked");

    Intent intent = new Intent(getActivity(), GPSService.class);
    intent.setAction(util.STOP_DRIVE);
    getActivity().startService(intent);
}

在清单中，我的应用程序标签中有这个

And in my manifest I have this in my application tag

<service android:name=".GPSService"></service>

我的问题是:在清单中注册了服务后，为什么会收到注册服务的错误消息，该如何解决?

My question is:Why am I getting the error message for registering the service when I have the service registered in the Manifest and how do I fix it ?

如果您需要更多信息，请告诉我.干杯.

Let me know if you need any more info. Cheers.

推荐答案

您的方法startDrive错误

private void startDrive()
{
    Log.w("rakshak", "Start drive clicked");

    Intent intent = new Intent(getActivity(), GPSService.class);
    intent.setAction(util.START_DRIVE);
    getActivity().startActivity(intent);
}

您使用的是startActivity而不是startService.另外stopDrive()正在重新启动服务

you are using startActivity instead of startService. Also stopDrive() is starting the service again
