使用最新版本的百度地图需要注意的几个地方：
1、libs文件夹下要有android-support-v4.jar、baidumapapi_v2_1_0.jar、locSDK_3.1.jar三个jar包和armeabi文件夹。
2、布局文件要写成<com.baidu.mapapi.map.MapView />，旧版本是写作<com.baidu.mapapi.MapView />的。
3、AndroidMainfest这个配置文件要把该添加的东西都加上。比如各种权限、比如屏幕支持、比如百度地图服务
<service
android:name="com.baidu.location.f"android:enabled="true" android:process=":remote"></service>
等
4、不要忘了申请自己的密钥。
……时间有限，就写这么多吧，遇到问题就百度一下，基本上也就解决了。
噢，附上自己的demo和各个链接。
百度地图API>Android SDK>相关下载sdk下载（/map/sdkandev-download.htm ）
百度地图API>Android SDK>申请Key申请key的链接（/map/android-mobile-apply-key.htm）
百度地图API>定位 SDK>Android 定位SDK> 定位sdk的链接 （/map/geosdk-android-download.htm）
1、代码结构：
2、各个类的大致作用：
(1) Cheeses.java填充没有用到的Fragment的内容
(2) DemoApplication.java从百度地图sdk demo中直接拿来的；主要用来处理与key相关的操作
(3) MainActivity.java实现适配器，完成不同Fragment之间的切换
(4) MapFragment.java定位相关的操作
3、附上主要类的源码：
(1) MainActivity.java
