What is the issue here! Please help me out!

I have the same problem, it seems like Google repo is missing this dependency. I checked the repository and gms folder does not contain any published versions.

So as a quick fix I added another repository, that has it:

repositories {
    maven { url 'https://dl.bintray.com/android/android-tools' }
}

EDIT: Since this is only a temporary solution and I consider it as a workaround so I am able to continue developing. I will remove this depencency later when Google repository will contain the depency or we know where they moved it.

Try adding another maven repository to your project gradle file. For example:

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

If that doesn't work, adding the OneSignal gradle plugin, also to the project's gradle, might do the trick (as suggested in this answer).

apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'
