在Android 5.0以上,使用 apktool 2.0, 对framework.jar包重编译时,可能会出现如下错误:
-
I: Using Apktool 2.0.0-RC4
-
I: Checking whether sources has changed...
-
I: Smaling smali folder into classes.dex...

很多开发者之前遇到过framework.jar的函数超过限制,需要拆分,所以在Android 5.0以下的版本,会有诸如framework2.jar, framework-ext.jar, secondary-framework.jar这样的framework拆分包。但Android 5.0不再拆分jar包,而是直接拆分dex包,所以在framework.jar包中,会包含 classes.dex和classes2.dex这两个dex包,同样是为了解决函数超过限制的问题。
当其中某一个dex包的函数数量超过限制,在做apktool重编译时,就会出现如上错误。只需要将部分文件挪到另一个dex包中便可解决这个报错。
