Using ProGuard with Android.

Question

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

"Waiting for Java type to"; line 23 of the file ... "

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

Thank.

Answer 1

The problem is here:

native ;

Try changing it to:

native <methods>;

From looking at the error message provided by your compiler, it seems that the compiler practically tells you what the problem is.

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

I lost count, but it looks like this line is line 23:

native ;

I do not know about you, but it does not look like valid Java at all.
