Things to Do Before Publishing Android Game

What things should android game developers do before publishing their android games?

I just finished my android game and is finally ready, but I need to do some stuff before I tried to publish it.

Besides, I think we can use this thread to share some tips on publishing your android games.

So... what else should developers do first?

Make sure that you export without debug.
Create appealing visuals and a trailer for your game's store page.
Share your game on several communities since number of downloads on launch is crucial.
