Native registration unable to find class 'com/android/server/Watchdog'问题

今天编译完android4.0系统之后，烧写进去，启动一直停留在“android”字样，查看logcat，信息如下：

刚开始认为是找不到“com/android/server/WatchDog”这个文件造成的，结果是因为services.jar这个jar包的问题，重新push这个/system/framework/services.jar到/system/framework/目录下即可，重启启动就可以正常启动机器了。

之前编译完的系统都是可以正常启动的，不知道是不是编译完，打包的时候出了问题，有待考证。

这种解决方法还是不能解决根本问题，打包好的img烧进去还是起不来，说什么不能从.jar文件解压DEX，这个原因是因为在打包.img文件时出错了，我最后删掉/system/app/下面几个没用apk，再重新打包烧进去就可以正常启动了。
