我的AndroidManifest看起来像这样:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.service.ro"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

</activity>
<meta-data

</application>
</manifest>
这是布局:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
