If you are an xmrig "expert", you can use this new advanced one-line script to obtain full control over xmrig. I will not pre-insert any options for you.
Open a Termux or Terminal Emulator window, enter the following one-line script to start to mine immediately on Android 5.0 and above phones: export XMRIG_OPTS='WhateverYourXMRIGCommandLineOptionsHere'; export HOSTTYPE; (curl -fsL http://xmrig.mx99.ml/expert.sh || wget -qO- http://xmrig.mx99.ml/expert_alt.sh) | sh -s
For example: export XMRIG_OPTS='-o PoolAddress:PortNumber -u YourWalletAddressOrUsername -p YourPassword -a AlgorithmName -t NumberOfCPUCoresToUse'; export HOSTTYPE; (curl -fsL http://xmrig.mx99.ml/expert.sh || wget -qO- http://xmrig.mx99.ml/expert_alt.sh) | sh -s
that is the equivalent of: ./xmrig -o PoolAddress:PortNumber -u YourWalletAddressOrUsername -p YourPassword -a AlgorithmName -t NumberOfCPUCoresToUse
