android百度地图打包混淆 用不了No such file or directory (2) com.baidu.mapapi.BMapManager.init(Unknown Source)

调用了百度地图地图开发包是baidumapapi_v2_1_1.jar，定位SDK版本是locSDK_3.3.jar

调试的时候能运行！可是打包签名后就运行不了！

baidu  google 了好久！最后还是自己解决的！

解决方法如下：

-keep class com.baidu.** {
  *;
}

记住别

-keep class com.baidu.** {
  public protect *;
}

否则就报错：
