解决方案

<使用库机器人:名称=com.google.android.maps/>

应该包含在<应用> 节点,而不是<活性GT; 节点。这应该解决的问题,因为截至目前为止,你是不是要求对地图的权限。

解决方案

The

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

should be contained in the <application> node and not the <activity> node. That should fix the problem because as of now, you are not requesting for the maps permission.
