Bitcoin mining with an Android phone is possible but not profitable I will explain why
Bitcoin mining is a puzzle where different miners compete  each other to solve the given puzzle and the miner who solves the puzzle fastest gets the reward. Imagine playing a game with your android phone and your competitor are using advanced computer for the same game, there is a very low probability that you will win that game. So we can see that mining Bitcoin is possible with Android phone but has a low probability of receiving a tangible profit from it. Also keep in mind that most of those apps on Android phone claiming to mine Bitcoin are scam and not profitable
My advise is that mining Bitcoin with Android phone is a waste of time and can damage the phone. instead focus on buying and selling of cryptocurrency with your android phone.
