Point your JAVA_HOME variable to C:\Program Files\Java\jdk1.8.0_xx\ where “xx” is the update number (make sure this matches your actual directory name). Do not include bin\javaw.exe in the pathname.
NOTE: You can access the Environment Variables GUI from the CLI by entering rundll32 sysdm.cpl,EditEnvironmentVariables. Be sure to put the ‘JAVA_HOME’ path variable in the System variables rather than the user variables. If the path variable is in User the Android Studio will not find the path.
