进程：无法使用 Intent 启动服务 com.google.android.gms.checkin.CheckinService

Question

我正在尝试构建一个 Google 地图应用程序，但在我的 LogCat 中不断收到它。我在清单中拥有所有权限和元数据集，但仍然对这个错误感到目瞪口呆。已在 SO 上到处查看此特定错误，但没有发现与 com.google.android.gms.checkin

相关的任何内容

关于我的结构层次结构。 MainActivity 扩展了 ActionBarActivity，在操作栏下方添加了三个选项卡。每个选项卡都有自己的片段。在gMapFragment 上，我从我的GPSTrack 类创建了一个GPSTrack 对象，该类扩展了Service 并实现了LocationListener。

问题是，当我启动应用程序时，我收到以下消息：

我已正确导入所有库，我什至将 google-play-services.jar 添加到我的 libs 文件夹中。我还通过 CMD 将 Google Play Services APK 安装到了我的模拟器上。

此外，我的GPSTrack 类中的LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); 总是返回null。

为什么会这样，我该如何解决这些问题？希望能得到解释以及解决方案，我想了解这里发生了什么。

在<application />里面添加了这个

        android:label="@string/service_name" >
    </service>

但仍然在 logcat 中获取 location == null

Answer 1

您应该在应用程序清单文件中注册您的 Service 类，即 GPSTracker 类：

<service
  android:name="MyService"
  android:icon="@drawable/icon"
  android:label="@string/service_name"
  android:exported="false"
  >
</service> 

添加<permission>标签：

 <permission
        android:name="com.app.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

Answer 2

我在实际设备上对其进行了测试，它能够获取我当前的位置。我想知道为什么模拟器不起作用！

更新

这对我有用：

private GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
    @Override
    public void onMyLocationChange(Location location) {
        //Do something when location changes
    }
};

然后在您的地图设置方法中，您可以调用：

GoogleMap.setOnMyLocationChangeListener(myLocationChangeListener);

停止Google Play Services Has Stopped 问题

1. 我下载了 Genymotion 模拟器
2. 已安装 ARM
3. 已安装 Google Play 服务 APK
4. 现在可以通过模拟 GPS 使用 Google 地图
