问Android不能膨胀MapFragment

EN

The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 6171000 but found 0.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

<?xml version="1.0" encoding="utf-8"?>
