4 min readJun 26, 2020

In this chapter, it’s simple. You can learn how to install Java8 and Android Studio on Ubuntu. So you can test the mobile app locally or on a Virtual Host. Here is the menu:

👍1. Install Java 8
🖖🏻2. Install Android Studio
👀3. Add NDK r21!

👍1. Install Java 8

The Android Studio is using Java 8 as its entry-level programming language. So you shall install Java 8 in the Ubuntu, too.

Open the terminal,

homanadmin@LAPTOP-THUV2CQ5:~$ java -versionCommand 'java' not found, but can be installed with:sudo apt install default-jre              # version 2:1.11-72, or
sudo apt install openjdk-11-jre-headless  # version 11.0.7+10-3ubuntu1
sudo apt install openjdk-13-jre-headless  # version 13.0.3+3-1ubuntu2
sudo apt install openjdk-14-jre-headless  # version 14.0.1+7-1ubuntu1
sudo apt install openjdk-8-jre-headless   # version 8u252-b09-1ubuntu1

None can be found. Let’s install it.

sudo apt-get install openjdk-8-jdk

After the installation, let’s check again.

homanadmin@LAPTOP-THUV2CQ5:~$ java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1ubuntu1-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

Good, let’s find java where it is installed /usr/lib with find command:

find /usr/lib -path ‘*java’

$ find /usr/lib -path '*java'
/usr/lib/jvm/java-8-openjdk-amd64/bin/java
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

The JDK and JRE are found. Let’s set the environment.

$ cat >> /etc/environment <<EOL
> JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
> JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
> EOL
bash: /etc/environment: Permission denied

Failed! You need “sudo” to override the permission. At first, I copy those two lines to notepad. In X Server, I will use “nano” editor.

$ sudo nano /etc/environment
[sudo] password for homanadmin:

I paste back from the notepad. Ctrl+X and save it. Let’s check.

homanadmin@LAPTOP-THUV2CQ5:~$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre

Java is ready.

🖖🏻2. Install Android Studio

In the beginning, we need to check which version of Android Studio we shall install, 64bit or 32bit.

$ lscpu
Architecture:        x86_64
CPU op-mode(s):      32-bit, 64-bit
 ...

Obviously, it’s 64 bit. Now, let’s download the file from Android Developer site.

https://developer.android.com/studio

After you download the file, you will found it in your Download folder.

Let’s extract the file in the Download folder.

All of the private applications will go to /usr/local folder.

Right-click and open the terminal.

Let’s move the unzipped folder to /usr/local.

sudo mv android-studio /usr/local

Let’s check.

~/Downloads$ cd /usr/local
/usr/local$ ll
