This is my build.gradle file:
buildToolsVersion = "29.0.3"
minSdkVersion = 21
compileSdkVersion = 29
targetSdkVersion = 29
ndkVersion = "20.1.5948944"
I am genuinely stuck at this point any help would be greatly appreciated

Answer 1

The problem was I had the latest version of the JDK (jdk-16.0.1) installed which was causing errors, by downgrading (to jdk-15.0.2) and updating my system variables again that solved the problem for me.
