Hi, I got an apk file. I extracted the source code from it by the methods provided on the net. On extracting and importing into the adt it does not shows errors but when i upload the same app on the phone it crashes "unfortunatly the app stopped working" I am a newbie and i want to learn the code and so if i get the correct code i will be learn it faster.. Is there any reason why the app doesnt start. Is it because we cannot extract the code properly from the app?? Thanks..
