Termux

download and install Termux.apk on your android, that you can get it from playstore or else !
run Termux !
write and run by click enter the scripts/ commands below :
- apt update
- apt upgrade
- apt install git
- apt install wget
- apt install proot
- git clone https://github.com/Neo-Oli/termux-ubuntu.git
- cd termux-ubuntu
- chmod +x ubuntu.sh
- ./ubuntu.sh
- ./start-ubuntu.sh
- apt update && apt upgrade
- apt install wget
- apt install proot
- apt install git
- apt install git build-essential cmake libuv1-dev libmicrohttpd-dev libssl-dev
- mkdir cpuminer
- cd cpuminer
- apt install automake autoconf pkg-config libcurl14-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++
- git clone https://github.com/tpruvot/cpuminer-multi
- ./build.sh
finish.

now you can try your pool (eobot account) some like this :
- ./cpuminer -a x11 -o stratum+tcp://x11.eobot.com:5555 -u eobot.991010 -p x -t 4
--  -a = algorithm
--  -o = pool
--  -u = user
--  -p = password
--  -t = thread / cpu

Then, next time and every time you want mining, because you had finished the installation on your android, you can do just :
- cd termux-ubuntu
- ./start-ubuntu.sh
- cd cpuminer/cpuminer-multi
- ./cpuminer -a x11 -o stratum+tcp://x11.eobot.com:5555 -u eobot.[Your ID of EoBot] -p x -t [how many cpu you want to allocate]

- exit for quit
