Just after updating The JDK to version 1.8, I found that Studio could not start, and The error “The environment variable JAVA_HOME does not point to an valid JVM installation” appeared. See The following figure for details:

Solution: 1, click on the desktop computer, right-click the properties. ; 2. On the left, select “Advanced System Settings”, environment variables, and configure your JAVA_HOME without a semicolon

This will enable You to launch Android Studio.
