Answer 1

我知道答案很晚了。但我在寻找解决同样问题的方法。也许会帮到某人。

Map Service是一个Android服务，它方便使用HERE SDK的应用程序之间使用共享磁盘缓存。此服务必须与启用here的应用程序一起嵌入和部署；否则，将通过OnEngineInitializationCompleted()回调返回MISSING_SERVICE错误代码。

要嵌入映射服务，请在AndroidManifest.xml文件中的 部分中添加以下行：

<service
android:name="com.here.android.mpa.service.MapService"
android:label="HereMapService"
android:process="global.Here.Map.Service.v2"
android:exported="true" >
<intent-filter>
<action android:name="com.here.android.mpa.service.MapService" >
</action>
</intent-filter>
</service>
