    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_SETTINGS" />

 <meta-data  
        android:name="com.baidu.lbsapi.API_KEY"  
        android:value="开发者 key" /> 

5.activity_main文件
activity_main:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

   <com.baidu.mapapi.map.MapView  
    android:id="@+id/bmapView"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    android:clickable="true" />

</RelativeLayout>

menu->main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.sjy.baidumap.MainActivity" >

    <item
        android:id="@+id/id_map_commen"
        android:title="普通地图"
