Using ProGuard with Android.

Question

I am trying to use ProGuard with Android. I have found several ProGuard scrips to use, with the following one being an example (I have found several others that are the same or very similar). However, when I try and run ProGuard using this script, I get the error:

"Expecting java type before ';' in line 23 of file ..."

I am completely new to ProGuard. Can someone explain what is going wrong here

Thanks.

The problem is here:

native ;

Try changing it to:

native <methods>;
