Tips on selling Android app?

[youforgotwhat]

I know this question's been asked many times before but I couldn't find a solid set of tips for this topic. I just launched my app today on the Play store. I posted on almost every Android forum I could find, I posted a YouTube video (about 22 views), and I really think my app looks very appealing. I've also submitted my app to about 4 or 5 review sites and created a Facebook page for it. Is there anything else that I can/should do in order to help my app gain more exposure? Thanks!
