Error in Encoding android code using Proguard

Question

I am using proguard to secure my android apk from reverse engineering.

But when I completed all the steps which is needed to on proguard tool in my app then it gives error like bellow:

[2014-03-11 10:55:04 - DemoProApp] Proguard returned with error code 1. See console
[2014-03-11 10:55:04 - DemoProApp] proguard.ParseException: Expecting type and name instead of just '***' before '(' in line 85 of file 'D:\Ranjana\New folder\DemoProApp\bin\proguard.txt',

And my Proguard-project.txt file is like bellow:

-dontwarn com.google.ads.** # Temporary workaround for v6.2.1. It gives a warning that    you can ignore

Answer 1

The error message refers to line 85 of file proguard.txt (not proguard-project.txt). That line appears to be missing a method name inbetween the return type (the wildcard ***) and the opening parenthesis for the method arguments.

Note that the Android SDK nowadays contains a standard configuration file that already specifies all the generic Android configuration for you (with -printseeds, -keepattributes, etc).
