Answer 1

更改此

class="com.google.android.gms.maps.MapFragment"

到

class="com.google.android.gms.maps.SupportMapFragment"

您缺少元标记。检查答案@

A required meta-data tag in your app's AndroidManifest.xml does not exist.

扩展FragmentActivity并使用SupportMapFragment。

可以删除

<permission
android:name="com.technowellservices.getmapv2.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission 
android:name="net.learn2develop.googlemaps.permission.MAPS_RECEIVE" />

Answer 2

更改此

<uses-permission 
  android:name="net.learn2develop.googlemaps.permission.MAPS_RECEIVE" />

到这个

 <uses-permission 
      android:name="com.technowellservices.getmapv2.permission.MAPS_RECEIVE" />

清理你的项目然后重新测试..
