Apps Android Studio won't connect to Java

[WinchestStoke]

I have been using Kotlin in Android Studio but now want to use the Java code but I just can't get it to connect to Java.

So, I have:

• Installed Java SDK into:

• Checked that it works OK:

• I have set the Windows environment variable’s:

But when I start a Java app I get:

Failed to find Build Tools revision 26.0.2

And in gradlew.bat I get: ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Any help really appreciated. Cheers!
