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

时间：2014-06-09 03:09:53

标签： android google-maps google-play-services locationmanager runtimeexception

我正在尝试构建Google地图应用程序，但继续在我的LogCat中接收此应用程序。我在清单中设置了所有权限和元数据，但仍然对此错误感到茫然。已针对此特定错误查找了SO，但未发现与com.google.android.gms.checkin

相关的任何内容

关于我的结构层次结构。 MainActivity使用操作栏下方的三个标签扩展ActionBarActivity。每个标签都有自己的片段。在gMapFragment我从我的GPSTrack类创建了一个GPSTrack对象，该对象扩展了Service并实现了LocationListener。

问题在于，当我启动应用程序时，我收到此消息：

enter image description here

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

此外，LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE);课程中的GPSTrack始终返回null。

为什么会这样，我该如何解决这些问题呢？ 也会感谢解释和解决方案，我想了解这里发生了什么。

修改

在<application />

内添加了此内容 
<service

        android:exported="false"
        android:enabled="true"
        android:label="@string/service_name" >
    </service>

但仍然在logcat中获取location == null

2 个答案:

答案 0 :(得分：0)

您应该在申请清单文件中注册Service课程，即GPSTracker课程：

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

添加<permission>代码：

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

P.S：如果您需要参考，可以按照link

答案 1 :(得分：0)

我在实际设备上测试了它，它能够抓住我当前的位置。我想知道为什么模拟器不起作用！

<强>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，您只需致电：

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. 已安装的Google Play服务APK
  4. 现在可以使用带有模拟GPS的Google地图
