Could not find com.google.gms:google-services:4.0.1 [duplicate]

Answer 1

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'

Answer 2

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.
