I'm sure this question will be appearing a million and one times in the next couple of weeks, but this seems to be the answer. You need to set the JDK_HOME environment variable to point to your Java installation. – Tubule

My problem was caused because the character '&' was in the path (in my Windows username). – Roughen

Answer 1

For debugging it is very helpful to start C:\Program Files (x86)\Android\android-studio\bin\studio.bat.

That points out what is wrong. In my case I had to update my JDK_HOME environment variable to point to the currient installation.

From the android documentation (this part was published after I wrote my answer):

Known issue: On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.

Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21.

As for me problem was that the variable JAVA_HOME was not set too. Control Panel - System - Advanced system settings - Environment variables add JAVA_HOME with value c:\Program Files\Java\jdk1.7.0_02\ for example (if yoour machine runs under win). – Heptangular

Yeah indeet I missed to add this :) – Malignancy

Optionally you can add %JAVA_HOME%\bin to PATH string - this allows you to run commands from \Java\jdkxxx\bin\ directly without specifying full path. "java -version" for example – Heptangular

Google should have added an error message. This problem (which should not be there in first place) is wasting time of millions of developers. – Seavir

Answer 2

The launcher is not finding your JDK setup. Make sure you have correctly set one of these environment variables: ANDROID_STUDIO_JDK, JDK_HOME, JAVA_HOME

Thank you for answer. I was facing same issue for Ubuntu. I configured JDK_HOME by following command: export JDK_HOME=/usr/lib/jvm/java-1.7.0-openjdk-i386 – Knop
