如何在Android中集成Google Map？

标签： android google-maps

我想在Android应用中实施Google Map。我还按照Google控制台api的所有步骤操作。 但在运行时，我的应用程序崩溃并得到有关片段的错误，我不明白。我还在app中添加了google play服务库。有人请帮助我。谢谢。提前感谢。

这是我的日志信息。

你应该

  <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

在<application>

中的manifest.xml标记中

答案 1 :(得分：1)

您应该在Manifest.xml文件中添加此权限

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

<uses-permission android:name="com.example_map.demomap.permission.MAPS_RECEIVE" />

并在<meta-data>

中添加此<application> 
<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
