android 老是报ClassNotFoundException

今天遇到了个问题，程序一直报ClassNotFoundException，已经确定AndroidManifest.xml文件已经配置了但是一运行就报错

04-05 19:24:04.925: E/AndroidRuntime(11198):
java.lang.RuntimeException: Unable to instantiate
activity ComponentInfo{com.example.travelmate/com.example.travelmate.SplashActivity}:
java.lang.ClassNotFoundException: Didn't find class "com.example.travelmate.SplashActivity"
on path: DexPathList[[zip file "/data/app/com.example.travelmate-2/base.apk"],
nativeLibraryDirectories=[/data/app/com.example.travelmate-2/lib/arm, /vendor/lib, /system/lib]]

百度也没百度出来结果，最后google了一下，解决了。

解决步骤大概是

右击项目打开properties

选择Java Build Path

选择Order and Export

然后把Android Dependences取消勾选

clean一下项目就好了
