I downloaded a apk file & decompiled it by using decompileandroid.com .I got a zip file extracted the contents & modified one jpg file in res>drawable folder. Then i compressed it to zip file. How should i convert it into apk file ?
I think the problem is with the signing process. I have no META INF folder in the app,but i don't know how to get it.I don't know how to use jar signer. I am a newbie to android so please help me.
