Question

我在尝试启动服务时遇到“未找到活动”异常。我在Manifest中注册了服务。添加我认为的相关代码和LogCat。如果您需要再看，请告诉我。

我的服务类：

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。

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);
}

在我的清单中，我在我的应用程序标签中有这个

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

我的问题是：当我在Manifest中注册了服务时，为什么会收到注册服务的错误消息？如何解决？

如果您需要更多信息，请与我们联系。欢呼声。

Answer 1

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startActivity代替startService。此外stopDrive()再次启动服务

Answer 2

GPSService是服务。它不是活动。你不能这样做

 getActivity().startActivity(intent);

而非do startService(intent);
