Micro Niche Sites but with Android APPS?

Hi Internet Marketers!!
I'm an Android Developer for 2 years now. Do you think it would be a good idea to make a lot of apps for different niches publish them and try to get at least 1000 uv a day. I dont know whtas the ecpm in niches sites, but in apps it's around 1$ and there are more monetization methods!

What do you think??
