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:

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
