This one does 55 different coins. I have never used their app but I do use their plugin to accept a several coins on my website and it works pretty good for that.
edit: I suppose I could actually paste the link https://play.google.com/store/apps/details?id=net.coinpayments.coinpaymentsapp
The official one is still in development, however its supported via the coinpayments one HERE
