I have installed Android Studio and I followed all steps described here

But when I start studio.sh I got an error with this message:

'tools.jar' is not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE

Can anyone here help me with this?

I don't understand the down voting. He asked a simple question. Is it a requirement to be a douche and down vote it? The community should support new users, not try to run them off. – Micrometer 6/6, 2013 at 16:7

I also had the same problem and found this post from Stackoverflow. Solved the issue. Stack Overflow post – Obtect 25/4, 2015 at 14:4

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 && 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

'dpkg --list | grep -i jdk' showed that I had old Sun's Java version 6, glad to get rid of that one. – Pollie 29/12, 2014 at 20:9

I didn't have to edit /etc/environment for this to work. – Oidium 16/3, 2015 at 23:17

thanks its really helpful no need to edit JAVA HOME path – Ringo 31/3, 2015 at 10:47

i am not well in it but i got such messege : "OpenJDK shows intermittent performance and UI issues. We recommend using the Oracle JRE/JDK" What does it mean? – Kilkenny 14/3, 2016 at 9:37

they recommend you use Oracle's version of Java, the OpenJdk Java has issues – Beethoven 15/3, 2016 at 13:41

 sudo apt-get install default-jdk

That's all in ubuntu 11

Dramatization answered 7/9, 2013 at 17:2 Comment(6)

I already solved it. I can't use apt-get because I'm using Fedora. I use Yum. But thanks anyway.! – Kermanshah 10/9, 2013 at 13:26

Thanks @Elshan, worked like a charm. The interesting thing, is that after I did that Android Studio runs, but there's no JAVA_HOME variable set up. But I don't care since it works. – Outbalance 4/10, 2013 at 3:12

I cannot revoke my upvote, but I realized that it caused the version 6 JDK to install, and Android Studio is throwing errors like hell. So it doesn't work like a charm. – Outbalance 4/10, 2013 at 3:33

@CsabaToth, I believe this might be because you're using an older Ubuntu distribution, on my 13.10 it definitely installs openjdk version 7. – Prosthodontist 8/1, 2014 at 14:28

@EugenevanderMerwe I did a dist upgrade, I'll check on that. – Outbalance 13/1, 2014 at 19:40

It also works for me in linux mint cinnamon 17.. but Android Studio prefers OracleJDK to be installed.. anyways i dont care if my stuff is working :D – Domela 24/10, 2014 at 10:38

This is caused by having JAVA JRE installed as opposed to JAVA JDK.

The solution is simple:

sudo apt-get install openjdk-7-jdk

It helped me "sudo apt-get install openjdk-7-jdk" – Spacesuit 26/1, 2016 at 17:34

This helped. On Ubuntu 15.10 I had to start studio with JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/ ./studio.sh – Dryer 1/2, 2016 at 22:43

"sudo apt-get install openjdk-7-jdk" This is the secret.. Nice! Thanks! +1 – Mclellan 18/8, 2016 at 3:3

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

Sorry. I didn´t told about my operation system: linux(Fedora 18 64). I have created and configured JAVA_HOME and PATH but I´m still getting this message. – Kermanshah 17/5, 2013 at 14:7

Widows 7 64 bit.

JAVA_HOME point to my JRE (NOT JDK) directory
Coping of tools.jar from JDK\lib directory to ANDROIDSTUDIO\lib directory solve the problem

Works prefectly on windows 7 64 bits! – Milore 30/8, 2016 at 21:9

This worked perfectly when I installed Android Studio via Wine on Mac OSX El Capitan. – Ticktock 4/10, 2016 at 6:23

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 had the same problem on a new installed Linux Mint 16. To fix this you just need to type command

sudo apt-get install openjdk-7-jdk

And that's it. You even do not need to add repositiries or creating JAVA_HOME in your environment.

First check if the Java JDK is installed correctly:

dpkg --list | grep -i jdk

If not, install the JDK:

Download the latest version of the JDK from Oracle: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Extract it to the appropriate location in your machine. Get the extract location:

vi ~/.bashrc or vi ~./ bash_profile
```
JAVA_HOME=/home/user/installs/jdk1.7.0_40
PATH=$JAVA_HOME/bin
```
source ~/.bashrc or source ~/.bash_profile
After the installation you can check it:
```
java -version
which java
```
If all things are correct then the right the answer should be something like this:

java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)
Append the following statement to studio.sh the file in android-studio/bin directory:
```
JAVA_HOME=/home/user/installs/jdk1.7.0_40
```

Finally start your Android Studio with the following command:

./studio.sh

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

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.

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.

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

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:

Hope this helps.

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.

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

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 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)
