Can I link my free app to my paid premium app?

In case you want to link from your free (trial) version of your app to your premium (full/paid) version in the App Center, you can use the following URI: 'appcenter://package/' in a view intent:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("appcenter://package/"));
startActivity(intent);
