百度地图自定义Marker

最近写了百度地图的Demo，所以总结下遇到的问题；

1.首先在百度地图中创建应用时用到 发布版SHA1是在Preferences下的Android下的Build中;
2.在使用百度地图时，先要创建一个Application的类，中间引用 SDKInitializer.initialize(this)// 在使用 SDK 各组间之前初始化 context 信息，传入 ApplicationContext；

3.在清单文件中配置应用的权限及配置com.baidu.lbsapi.API_KEY；

4.使用时候将你用到的jar包添加上，离线包需要的添加上；

如下是我写的例子的2个效果图：

一共是3个小例子：定位自己，添加marker，和轨迹；

在写的时候一共遇到2个问题：

1.在使用定位的时候，忘了加定位的离线包，所以一直定位到大西洋，定位错误；

2.在添加轨迹的时候，我使用模拟器的时候，一直蹦溃没有处理好，但是用真机时候又可以了。

如下是代码下载链接：http://download.csdn.net/detail/qq_29774291/9718205

如下是主要代码：
