Error: Invalid Gradle JDK configuration found. Open Gradle Settings. Platform SDK does notpoint to valid JDK

So I thought I had everything ironed out with my JDK versioning errors after installing 1.8 JDK over 1.7 JDK.  But... I start working through the super simple "Happy Birthday" sample from Udacity's free Intro to Android Studio Class.  Setup a new project and woopsy, get the following:


Course of action to correct.

In Android Studio, navigate to File -> Project Structure -> SDK Location

Set the JDK location to the 1.8 (or whatever is current) correct SDK you wish to use. 

Hopefully all joy and happiness after that. 

I don't know if this fixes the JDK location for all projects.  If it doesn't, there will be another post coming shortly.

ERROR: java-version '1.7' is required / could not find java.dll / could not find Java SE Runtime Environment

I've been learning Android and had installed Java 1.7.  I installed Java 1.8 to get the latest version.  After installing I opened a command prompt and typed in "java -version" to make sure everything had installed properly.  Woops, got the nastiness below!

C:\windows\system32> java -version

Error: Registry key
'Software\JavaSoft\Java Runtime Environment'\CurrentVersion' has value '1.8', but '1.7' is required.
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.

 

Lots of hits out there about modifying registry and deleting files to fix the error.  Those seemed messy.  Here's a simpler fix that worked for me.

  • Open Control Panel\All Control Panel Items\Programs and Features
  • Uninstall new version of java (1.8)
  • Uninstall old verrsion of java (1.7)
  • Reboot
  • Install java 1.8
  • Set java_home to new variable via ENVIRONMENT to point to the java 1.8 path

Good to go after that point.
