new AppUpdater(this)
   .setUpdateFrom(UpdateFrom.JSON)      
   .setUpdateJSON("https://raw.githubusercontent.com/famfir18/UpdaterJson/master/update.json")
   .start();

I managed to check the application with the latest version and direct to play store, but when i get into the play store there are 2 option (Uninstall & Open), but the button for Update doesnt appear. My users must to uninstall it and then install again for update.

Is there a way to show the update button on the google play store?
