Answer 1

just wanted to leave an extra tip. When I installed Android Studio, I read somewhere that it was recommended to leave this configuration (with the '+' symbol)

build.gradle (project)

dependencies {
        classpath 'com.android.tools.build:gradle:+'
        .....
        #more lines here
}

However, the project I am using uses an old version of gradle, and this line always requested the latest version. Took me a while to figure it out.

Answer 2

Check your proxy setting on Android Studio

File > Settings > Appearance

&

Behavior > System Settings > HTTP Proxy

Answer 3

Here was how I resolved the issue. Change the root build.gradle file:

dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'

    .....
        //other codes here
    }
