将Google添加到应用程序中作为另一项活动

Question

我有问题。我正在尝试添加到我的应用程序Google作为一个新的活动。我已经修改了很多次我的代码，但是当我想打开包含Google的活动时，我的应用程序正在关闭。

我正在使用Android，并在Huwei上测试我的应用程序。

也许有人会有什么主意。

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Map接收权限。
• 在您的Maps_activity.java类中，请将"R.layout.activity_maps_“改为"R.layout.activity_maps”
• 在清单文件的应用程序标记中。

希望这会有帮助！！
