I was facing similar problem on Windows 7 x64 professional edition. Please note following steps to fix this problem.

1. tools.jar is missing from required path if you are using jdk1.7 x64 bit version.

2. Please install x86 version of jdk1.7

3. 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.

4. Launch 32 bit application from /android-studio\bin folder.

I tested and verified these steps on windows 7 with 32 bit jdk1.7

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)

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

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:

1. sudo gedit /etc/environment
2. 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)
3. export JAVA_HOME
4. save and exit editor.
5. Load the path variable again using the terminal: . /etc/environment

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.
