讨论了在精简ROM过程中遇到的系统框架依赖odex文件的问题，并提供了相关解决方案，包括分析logcat日志、理解odex依赖关系以及在进行精简时保持框架的odex化。
使用言文605比较满意，但精简了不少系统的东西，现在想加回去，碰到带有odex的原版程序跑不起来的问题，经过抓取logcat，查看android源代码, 相应的odex分析，找到原因是此rom的/system/framework下的文件都是重新deodex成一个apk的，而原系统中framework下都是有odex,而且system/app目录下的odex文件都是依赖/system/framework目录下的odex文件，如果找不到就不能加载 ,log 如下

所以建议各位大大做精简rom时, framework目录下的东东最好odex化，即使deodex过后，也要再odex
