How to solve "Version code 1 has already been used. Try another version code"?
Check your build settings and make sure you increase both, the version code and the version. The version can be a string and represents the version shown to the user (ie: 1.01 or 2.0.2).
The version code is just a single integer and has to be greater than the last everytime an uploaded apk/abb is published. Even when published for testing. Make sure you also increase the version string or google will complain as well.
