If you are annoyed that "Sources for Android 26" are not yet available via SDK manager, this might be for you:

1. Collect source files

mkdir android-sdk-source-build
cd android-sdk-source-build

mkdir -p frameworks/base

#!/bin/bash

SOURCE=$1

if [[ -z $SOURCE ]]; then
  echo "Usage: $0 [source]" >&2
  exit
fi

sudo mkdir -p /mnt/sd1
