Offlate I got some time to write a blog post to explain how to hack an android app. I always thought that hacking is very difficult. But later i realised that it is not that difficult.
There are few tools you need to start with android hacking. You would need to decompile the apk, and modify the smalli code,and then recompile the same. Zipalign and sign,. you are ready to go.
There are few things to keep in mind when hacking, first you need to study the application to find places where we see the checks, for example may be the screen where the password is asked etc. Then you can search the String resources with the Strings on those screens to find the logic related to F password cheek etc,you can then either change the logic or skip the code, os may be make that function return true inspte of the failed cheek. You are done, then recompile and see if it is working. If it does not don't be disappointed. You need to try again untilyou get the right hack.
Remember one thing most of the times the changes needed are not more than one line of code change. You would be surprised to see such week apps, But whatever they make to protect the app it is easy to hack.
Enough for now. This is kind of Introduction to hacking, you may need to google to find out how to decompile, recompile, sign, zip align etc, but at the end of the day it is fun
