Solution To: cannot start Android Studio. No JDK found.


cannot start Android Studio. No JDK found. Please validate either ANDROID_STUDIO_JDK, or JDK_HOME or JAVA_HOME points to valid JDK installation. ECHO is off. Press any key to continue


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, add new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21.
