After so many hours of my free time, I\'m ready to publish my very first app to the play store, but sadly I\'m having difficulties uploading the signed app.
In my case the problem was occuring because I changed package name before releasing and forgot about changing directory names. Project was still compiling but it was impossible to release it on google play.
Check in any java file if you have red underlined package name with error
'Package name xxx.yyy.zzz does not correspond to the file path 'xxx.eee.zzz'.
