No, I didn't find any android yet. I tried all out, that looked like bots, but they didn't work, where not updated for years or where scam.
But there would be a possibility maybe to make a half automatic bot with dynamic orders.
Example: You exchange BTC to doge. When price falls under 10 %, doges will get sold. When the price raises the selling point will set automaticly go up. A kind of trail stop order.
That is no bot.
