and manifestfile is this

推荐答案

我有这个问题，并通过以下两个步骤解决了这个问题：

I had this problem and solved it by the following 2 steps:

1）把下面一行在应用程序（AndroidManifest.xml文件中重要的）元素。

1) Put the following line in the application (important) element of AndroidManifest.xml file.

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

2）延伸，而不是活动MapActivity。

2) extend MapActivity instead of Activity.

享受！
