1. You can install Java, just by writing: sudo apt-get install default-jdk in terminal window, or follow these steps: Download Java, in my case I downloaded this one.
2. To install Java, open terminal window, go to the location where you downloaded Java, and write:
tar zxvf jdk-8u45-linux-x64.tar.gz
3. After installing Java write something like:
export JAVA_HOME=/home/myUserName/myDownloadPlace/jdk1.8.0_45
Of course change myUserName/myDownloadPlace.
or write:
sudo gedit /etc/environment
then in environment write:
export JAVA_HOME=/home/myUserName/myDownloadPlace/jdk1.8.0_45
4. Then write:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
5. Finally download Android Studio, extract it, go to bin folder, in my case that is something like:
/home/myUserName/Downloads/android-studio/bin
6. Execute:
./studio.sh
7. Go to File -> Project Structure -> JDK location box: enter and browse to your Java JDK.
8. Download from here and install Java JRE, and I copied downloaded version to folder /home/myUserName/Android/Sdk/tools/lib/monitor-x86_64/jre
