Android Bash

A docker image that builds bash binaries for Android.

For each supported Android CPU architecture (x86/ARM/MIPS) it will build both PIE (position independant executable) and a non-PIE binary.

PIE binaries are supported on Android 4.1+ and mandatory on Android L and above.

Automated Build

$ docker run -v $(pwd):/target sonelli/android-bash
$ find .
./x86/pie/bash
./x86/nopie/bash
./arm/pie/bash
./arm/nopie/bash
./mips/pie/bash
./mips/nopie/bash

Manual Build

$ docker run -i -t -v $(pwd):/target sonelli/android-bash /home/admin/shell
$ vi ~/build (tweak away)
$ ~/build
$ exit
$ find .
./x86/pie/bash
./x86/nopie/bash
./arm/pie/bash
./arm/nopie/bash
./mips/pie/bash
./mips/nopie/bash
