I implemented the most important two methods for a first version of the NE, if you need something else just give me know. ---

whoah! This feature was ofter requested all around. Can you please link to a game or a demo on the Play Store that utilises this NE already? ---

Unfortunately, for now, I have only a dirty demo in test mode, but I’ll try to do an example later on this week. Also, I wanna add new functions for this NE. ---

Interesting fact: players who launched the Google Instant App on a page on Google Play account for approximately 10-20% of the number of players who installed the game. In my opinion, this is a pretty good result, considering that we are talking only about organic traffic (from advertising you can launch the Instant app via a direct link). I didn’t bother much and just using the Instant App extension I check if the game is an instant application, if yes, instead of restarting at the end of the level, I suggest installing the full game (almost the same apk, but on a permanent basis). Even with this approach, the game fits into a 4Mb limit for applications (for games, a 10Mb limit). ![JvnhfSAkavw](https://forum-defold.b-cdn.net/uploads/default/original/2X/1/1a1ac800393a79d14112fb2926a8235fc4fbd69b.jpeg) ---

I’ve released version 1.0.0. Added new methods: `instantapp.get_cookie_max_size()` `instantapp.get_cookie()` `instantapp.set_cookie()` Those methods provide a possibility to communicate between instant application and the main application. ---

Hi @AGulev is there any chance you could please provide updated instructions for building the instant app as an AAB in the latest version of Defold? It says [here](https://developer.android.com/topic/google-play-instant/overview) “All new instant experiences must publish with instant-enabled app bundles”. ---

Yes, of course. I’ll take a look. ---

Thanks, trying it now. One thing I’m confused about is the version codes. How do I set a seperate version code for the instant app and the installable app? Do I need to have a seperate Defold project for the instant app? ---

> [@jm1175](#): > > Do I need to have a seperate Defold project for the instant app? No I don’t think so. You need to manually change the version code when you build. Or if you build from the command line you can script it.
