Android Development Environment
Host PC requirements
The host development environment for Android is based on Ubuntu and Debian, please install one of the following
- Ubuntu version 14.04/16.04 64bit LTS
- Ubuntu LTS 14.04 64 bit - Download it from : http://releases.ubuntu.com/14.04/ubuntu-14.04.6-desktop-amd64.iso
- Ubunut LTS 16.04 64 bit - Download it from : http://releases.ubuntu.com/16.04/ubuntu-16.04.6-desktop-amd64.iso
- Debian 8.4 64bit https://www.debian.org/releases
Minimum hardware requirements for the build machine (A physical build machine is recommended):
- CPU: Intel / AMD 2.3 GHz Quad Core
- RAM: 16GB
- Free storage: 500 GB (SSD recommended)
- Internet connectivity
Notes:
- The build process requires ~135GB of free storage space. Before starting a build, make sure you have adequate free space available.
- Do not use other Ubuntu or Debian releases other than the ones recommended above.
You can create a bootable USB drive for installing the host OS. E.g.
- Using Windows: https://rufus.ie
- Using Linux: https://help.ubuntu.com/community/Installation/FromUSBStick
Install required packages on host PC
Before you begin, make sure you installed correct version of build OS on your build machine. You can verify by using below commands
$ uname -a | grep "x86_64"
You should get output like below
Linux user-desktop 4.15.0-72-generic #81~16.04.1-Ubuntu SMP Tue Nov 26 16:34:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Notice the "x86_64" string, if you have installed other (32 bit version) such OS flavor for Android build is not supported currently.

Install the OpenJDK
Android Nougat requires OpenJDK 8.
To install it:
$ sudo apt-get update $ sudo apt-get install openjdk-8-jdk
If your Ubuntu version is missing the package (which shouldn't happen), add the PPA repository and run the previous commands again:
$ sudo add-apt-repository ppa:openjdk-r/ppa
Update the default Java version by running:
$ sudo update-alternatives --config java $ sudo update-alternatives --config javac
