Unable to install Android Studio on elementary OS

Question

I have downloaded Android Studio for Linux and extracted it using GUI.

Instructions for install are here

The first command:

cd Downloads

puts my directory to

thomasshera@thomasshera-Satellite-Radius-P55W-B:~/Downloads$

Then the second command " ./studio.sh" gives me:

"bash: ./studio.sh: No such file or directory"

How fix this?

EDIT 1: Ravan, it gives me this error message;

ERROR: Cannot start Android Studio
No JDK found. Please validate either STUDIO_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation.
thomasshera@thomasshera-Satellite-Radius-P55W-B:~/Downloads/android-studio/bin$

EDIT 2: output of java -version:

The program 'java' can be found in the following packages:
* default-jre
* gcj-4.8-jre-headless
* openjdk-7-jre-headless
* gcj-4.6-jre-headless
* openjdk-6-jre-headless
Try: sudo apt-get install <selected package>

EDIT 3: new output of java -version after installing JDK:

java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

EDIT 4: response of first part of Ravan's CLI install for JDK.

Important!!! For now, you should continue to use Java 8 because Oracle Java 9 is available as an early access release (it should be released in 2016)! You should only use Oracle Java 9 if you explicitly need it, because it may contain bugs and it might not include the latest security patches! Also, some Java options were removed in JDK9, so you may encounter issues with various Java apps.

Answer 1

I have very recently installed Android studio,

Instructions:

GUI:

• Download the Android Studio for linux, place it in home directory. (Not mandatory, but prefer)

• Unpack the downloaded ZIP, right click and click extract here.

• Go to android-studio --> bin --> click on studio.sh

CLI:

Download the Android Studio for linux, then run the commands to install.

sudo apt-get install unzip #if needed.
cd [location_of_Android_Studio_zip_file]
unzip android-studio-ide-141.2456560-linux.zip # replace with your zip file name.
cd android-studio/bin/
./studio.sh

"bash: ./studio.sh: No such file or directory"

You are not in correct directory. If you have Android studio in ~/Downloads folder, you have to navigate to ~/Downloads/android-studio/bin.

If you want to check use file file_name like:

Wrong directory:

ravan@ravan:~$ file studio.sh
studio.sh: ERROR: cannot open `studio.sh' (No such file or directory)

Corect directory:

ravan@ravan:~/android-studio/bin$ file studio.sh
studio.sh: POSIX shell script, ASCII text executable

EDIT:

See here for system requirements. You have to install java JDK (atleast 7).

To install java:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Then:

sudo apt-get install oracle-java8-set-default
