1. 注意 key 一定要在activity 前面

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" >
    <service
        android:name="com.baidu.location.f"
        android:enabled="true"
        android:process=":remote" >
    </service>

    <meta-data
        android:name="com.baidu.lbsapi.API_KEY"
        android:value="6dsXhPU5WWHcBxGwQtHZKIGfZZBorMZ5" />

2  .xml 文件

<com.baidu.mapapi.map.MapView
    android:id="@+id/map_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

</com.baidu.mapapi.map.MapView>

3. java文件
