Thank you in advance.

Answer 1

You also need to open up "build.gradle" script and change the classpath to latest gradle repository.... mine is 'com.android.tools.build:gradle:3.0.0-alpha3'

Hope this helps everyone

Answer 2

Your compileSdkVersion must be a number, not a String

Example:

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "com.yourpackage.yourapp"
        minSdkVersion 11
        targetSdkVersion 24
        versionCode 4
        versionName "1.3"
    }
    ...
}
