问题就在这里:

<meta-data
   android:name="com.google.android.maps.v2.API_KEY"
    android:value="AIzaSyC6TVk6gtR_i_.......**************"/> 

meta-data标记在这里需要一个integer,因此您必须在这里包含您正在使用的com.google.android.maps库的版本。您可能会在包含在项目中的lib中找到这一点,然后只需定义:

<meta-data
   android:name="com.google.android.maps.v2.API_KEY"
   android:value="@integer/your_google_maps_version" />
