It is a problem found in the new Android Studio 3.6 update. But it is basically not a problem.

All you have to do is the following:
To enable or disable Gradle's offline mode, first select View > Tool Windows > Gradle from the menu bar. Then, near the top of the Gradle window, click Toggle Offline Mode

Here are some screenshots:

This helped me I setup offline mode before upgrading to 3.6. Then when 3.6 opened the checkbox for offline mode was gone in Preferences menu. Thank you so much! – Rio Marie A. Callos Mar 01 '20 at 14:13
After Toggle offline mode, make a gradle sync it will tell you what to do in the rest. Thank you for the help @Asif Iqbal – user7418129 Mar 27 '20 at 04:47

I was going through similar issues last night, this is what worked for me :

Open the build.gradle file from your app folder, it should look similar to this

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

add google() to repositories in -buildscript and -allprojects, just like here :

buildscript {
    repositories {
        google()       // here
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
    }
}

allprojects {
    repositories {
        google()      //and here
        jcenter()
    }
}

In Android Studio, go to File -> Project Structure.. [ shortcut : Ctrl + Alt + Shift + S ]

In the Project tab -> Android Gradle Plugin Version -> 3.6.1 and Gradle Version -> 5.6.4 |||

Last, under the Module tab, make sure the compile sdk version is > 14 (ie: 25, 28 or 29..)

I opened an old project with Eclipse. For me, it helped to add the following in build.gradle:

apply plugin: 'com.android.application'

repositories {
    // order may be important!
    google()
    jcenter()
}

In addition, a few times I had to use File > Invalidate Caches / Restart.

The project that you are trying to build probably doesn't have the required SDK version. You can download it from the Android Studio within the "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK. Preferences Screenshot.
