将 Google 地图作为另一项活动添加到应用程序

Question

我有问题。我正在尝试将 Google Map 作为一项新活动添加到我的应用程序中。我已经更改了很多次代码，但是当我想打开包含 Google 地图的活动时，我的应用程序正在关闭。

我正在使用 Android Studio，我正在 Huwei Ascand 上测试我的应用程序。

也许有人会有一些想法。

问题解决了！。 cmets 中的解释！

Answer 1

您可以通过以下方式更新代码来解决此问题：

• 在清单文件中添加地图接收权限。

  <uses-permission android:name="package_name.permission.MAPS_RECEIVE"/>
  

• 请在您的 Maps_activity.java 类中将“R.layout.activity_maps_”更改为“R.layout.activity_maps”

• 在清单文件的应用程序标签中

   <uses-library android:name="com.google.android.maps" />
  

希望这会有所帮助！
