i think it is very difficalt to do.You cannot mine Bitcoin using the processor on an Android phone. Nowadays all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware called ASICs(application specific integrated circuits), usually in thermally-regulated data-centers with access to low-cost electricity. Think of a Bitcoin ASIC as specialized Bitcoin mining computers, Bitcoin mining machines, or bitcoin generators. Read more about ASICs at : Bitcoin Mining Hardware
However, it might still be possible to profitably mine some other available altcoins/crypto currencies using a GPU on a laptop/desktop. Instructions for setting up can be found at the crypto's official website/GitHub org.
To the best of my knowledge, the only crypto currency a person can currently mine using an Android device is Electronium. This is to be done via their App. (Functionality isn't yet active!!!!)
It seems impossible because of the many things which mining requires and a mobile phone does not possess. These softwares entire are not available in mobile phones and so for the time being mining with it is not possible. Mining needs a very strong processing system and also ASIC which is not installed in mobiles and therefore mining is not possible with mobiles. In the future it is possible because computer science is growing with the passage of time.
