--------------------编程问答-------------------- 类转换异常嘛 看causeby --------------------编程问答-------------------- java.lang.ClassNotFoundException: com.songge.rzg.GMIDlet in loader dalvik.system.PathClassLoader[/data/app/com.songge.rzg-1.apk]
类没找到 --------------------编程问答-------------------- 反编译一下/data/app/com.songge.rzg-1.apk，
看AndroidManifest.xml里是不是没有注册com.songge.rzg.GMIDlet --------------------编程问答-------------------- Caused by: java.lang.ClassNotFoundException: com.songge.rzg.GMIDlet in loader dalvik.system.PathClassLoader[/data/app/com.songge.
在/data/app/com.songge路径下找不到rzg.GMIDlet文件，仔细检查程序中的调用关系、返回类型，以及调用权限问题。
补充：移动开发 , Android
