For me  running Fedora 22  with Gnome 16 2  this solution helped me  In short  you should install the java-1 8 0-openjdk-devel  the development files of the JDK   Open the Terminal and search for the latest version of the JDK development package     dnf search jdk-devel Last metadata expiration check performed 12 44 51 ago on Mon Aug  3 22 20 24 2015                               N S Matched  jdk-devel                              java-1 8 0-openjdk-devel x86 64   OpenJDK Development Environment java-1 8 0-openjdk-devel-debug x86 64   OpenJDK Development Environment with                                         full debug on   sudo dnf install java-1 8 0-openjdk-devel

This is caused by having JAVA JRE installed as opposed to JAVA JDK   The solution is simple   sudo apt-get install openjdk-7-jdk   http   www maxmakedesign co uk development 2013 android-studio-tools-jar-classpath

I was facing similar problem on Windows 7 x64 professional edition  Please note following steps to fix this problem    tools jar is missing from required path if you are using jdk1 7 x64 bit version  Please install x86 version of jdk1 7 Set JDK HOME  C  Program Files  x86  Java jdk1 7 0 67  and update path environment variable as path  C  Program Files  x86  Java jdk1 7 0 67 bin  Note  Linux put the proper path  Launch 32 bit application from  android-studio bin folder    I tested and verified these steps on windows 7 with 32 bit jdk1 7

On Windows 7 just run the studio bat file in your android-studio bin folder with right click as an administrator  Now you get ask to import previous studio settings  Ignore this and on the next dialog you can specify the path to your jdk directory  That s all   Marcel

On my Linux Mint 17 3 install  I found these instructions incredibly helpful   The problem seems to boil down to the system s default Java being OpenJDK and Android Studio preferring Oracle s JDK  I actually did not perform the OpenJDK removal steps given in the tutorial  but only downloaded the Oracle JDK and set it as my system s default  Android Studio worked right away   In case the linked page ever goes away  the steps I took were  Download Oracle JDK  Mine was version 1 7 0 79   tar -zxvf jdk-7u79-linux-x64 tar gz sudo mkdir -p  opt java sudo mv jdk1 7 0 79  opt java sudo update-alternatives --install   usr bin java   java    opt java jdk1 7 0 79 bin java  1 sudo update-alternatives --set java  opt java jdk1 7 0 25 bin java   and  java -version   confirms the system is using Oracle s JDK  giving output like  java version  1 7 0 79  Java TM  SE Runtime Environment  build 1 7 0 79-b15  Java HotSpot TM  64-Bit Server VM  build 24 79-b02  mixed mode

Check if your Java JDK is installed correctly  dpkg --list   grep -i jdk   If not  install JDK  sudo add-apt-repository ppa webupd8team java sudo apt-get update  amp  amp  sudo apt-get install oracle-java8-installer   After the installation you have to enable the jdk  update-alternatives --display java   Check if Ubuntu uses Java JDK 8  java -version   If all went right the answer should be something like this   java version  1 8 0 91  Java TM  SE Runtime Environment  build 1 8 0 91-b14  Java HotSpot TM  64-Bit Server VM  build 25 91-b14  mixed mode    Check what compiler is used  javac -version   It should show something like this  javac 1 8 0 91   Finally  add JAVA HOME to the environment variable  Edit  etc environment and add JAVA HOME  usr lib jvm java-8-oracle to the end of the file  sudo nano  etc environment   Append to the end of the file  JAVA HOME  usr lib jvm java-8-oracle   You will then have to reboot  you can do this from the terminal with   sudo reboot   In case you want to remove the JDK  sudo apt-get remove oracle-java8-installer

You have 2 things you must check    verify that  etc environment file has the correct JAVA HOME and PATH values referring to your Java installation directory  verify that you have the correct Java version  maybe you are using a distribution of Linux which need a server version of Java  you may need this version like my case JRE for server

On ubuntu I have tried all the methods that are described here but none worked   What I did in the end was to    download JDK from oracle  extract the archive edit android-studio bin studio sh and add at the top   export JAVA HOME  path to jdk save the file and cd android-studio bin and launch Android Studio    studio sh

in OpenSuSE 13 1 and some 13 2 versions you also need to    install java-1 7 0-openjdk-devel package change the JAVA HOME path when starting the studio    For x86  JAVA HOME  usr lib jvm java-1 7 0-openjdk-1 7 0  sh studio sh  For x64  JAVA HOME  usr lib64 jvm java-1 7 0-openjdk-1 7 0  sh studio sh

I ran into this issue when I was referencing     drive   Program Files Java jdk1 8 0 65    in my JAVA HOME environment var instead of the Android Studio recommended    drive   Program Files Java jdk1 7 0 79     I am using the x64 version of the JDK on Windows 10 Pro   From the Android Studio installation instructions   Before you set up Android Studio  be sure you have installed JDK 6 or higher  the JRE alone is not sufficient    JDK 7 is required when developing for Android 5 0 and higher  To check if you have JDK installed  and which version   open a terminal and type javac -version  If the JDK is not available or the version is lower than version 6  download the Java SE Development Kit 7  http   developer android com sdk installing index html pkg studio

The problem is a bug on Fedora 20  The bug is very odd  if I have Google Talk plugin installed then Eclipse crashes  https   bugs eclipse org bugs show bug cgi id 334466   It s crazy for me  I thought that was Java version and with Java 6 my eclipse was still crashing  To solve this I should use gnome GTK instead KDE  Now it works  well   in gnome environment   Thanks for all answers

It s probably because you don t have jdk installed in your machine  I had exact same problem in first run  Open a terminal  CTRL ALT T  and type  sudo apt-get install openjdk-7-jdk   When done setup Java environment variable  Steps as follows     sudo gedit  etc environment Either in the beginning or end of the file write  JAVA HOME  usr lib jvm java-7-openjdk-i386  location may vary depending on the installation of your Java  export JAVA HOME save and exit editor  Load the path variable again using the terminal     etc environment   Couple of helpful links for further clarifications     How to install JDK on Ubuntu  Linux   How to set JAVA HOME for OpenJDK    Hope this helps

The error is self explanatory  you need to set your environment variable to JDK path instead of JRE here is it  JDK HOME  C  Program Files Java jdk1 7 0 07   check the path for linux   and here is possible duplicate Android Studio not working
