is there way to hook java method at runtime

[astonbitecode]

Hi.

You have opened this issue before and I asked for more details...

I would kindly ask again: Can you please describe what you try to achieve? There is no way to answer some question if there are no details.

for example, there is a jar file,which works for android os , I need to hook the unsupported method call in java code ,because that depends on native system api ,I just want to bypass it,

You cannot change the behavior of a method. If the method calls a native function, it will call it regardless.
