请帮我解决这个问题。

Answer 1

一个明显的错误

https://developers.google.com/maps/documentation/android/start

您的元标记必须是清单

中应用标记的子代

     <meta-data   // should be inside application tag.
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="********************************" />

更改此

     <permission
    android:name="com.venky.maps.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

到

    <permission
    android:name="com.example.newapp.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

例外“膨胀类片段”
