Preparing Your Android App for Updates
Before you can update your Google Play Store app, there are a few things you must do before building your app, and that is to update the VersionCode and VersionName of your app.
Once you've done that, you can now build your app. Make sure you use the .jks key store file you've generated as well as the proper passwords that you used when you first built the first public release of your application. This will be necessary in order for you to successfully update the app.
