Answer 1

I had the same problem and I checked all the above answer, I had a made a silly mistake because of which nothing worked for me. Just in case any of you do same mistake as mine try this.

1. Version can be a decimal number like 1.0 or 1.0.1 etc
2. But VersionCode cannot be decimal number It should be 1,2,3 etc and not 1.1 or 2.2

So in project/app/build.gradle

android {
defaultConfig {
    versionCode 1 // do not use decimal number here
    versionName "1.0" // you can use decimal number here.
    {...}
}
{...}
}
