原因：

     高德地图定位库的使用引起的，需要添加混淆代码。

以上是新版本必须要加的，下边给出最全配置：

-keep class com.amap.api.**{*;}//最重要的要加上这个处理，否则还会出现以上崩溃问题，官方没有该处理
#3D 地图 V5.0.0之后
-keep class com.amap.api.maps.**{*;}
-keep class com.autonavi.**{*;}
-keep class com.amap.api.trace.**{*;}
#定位
-keep class com.amap.api.location.**{*;}
-keep class com.amap.api.fence.**{*;}
-keep class com.loc.**{*;}
-keep class com.autonavi.aps.amapapi.model.**{*;}

#搜索
-keep class com.amap.api.services.**{*;}
#2D地图
-keep class com.amap.api.maps2d.**{*;}
-keep class com.amap.api.mapcore2d.**{*;}
#导航
-keep class com.amap.api.navi.**{*;}
-keep class com.autonavi.**{*;}
