您好, 现在很多app早已超过了65535的方法数限制, 请问微信tinker增量dex的方案如何兼容multidex? 谢谢回答.

Tinker是兼容MultiDex方案的，对于Dalvik，我们是采用将补丁Dex插入到pathlist的前面。对于Art平台，我们是采用parent classloader方案。Dalvik不采用parent classloader是因为Dalvik存在一个checkasses

如果增量dex可以直接插入pathlist的话,是否说明:

  1. 要想和multidex方案兼容则没有增量dex和旧dex合并的过程.
  2. 要想和multidex方案兼容则补丁dex是一个完整的dex文件, 和 nuwa 方案下发的补丁基本一样.

感谢回复 ^_^
