        classpath 'com.google.gms:google-services:4.0.1'

        // NOTE: Do not place your application dependencies here; they belong

the problem only appears after updating to the latest firebase version which is 16.

any help will be appreciated, Thanks

Answer 1

Using Android Studio, the correct repo for the library:

implementation 'com.github.valdesekamdem:MaterialDesign-Toast:0.9.0'

is currently at

https://maven.scijava.org/content/repositories/public/com/valdesekamdem/library/md-toast/0.9.0/md-toast-0.9.0.aar

So it is now available as an aar in this repo.

You can only use the .aar file directly as a local dependency:

Download and Use the .aar File Locally, steps:

a. Download the aar File from the working repo above.

b. Add the File to Your Project Place the .aar file in your app's libs directory.

c. Modify build.gradle Add this to your app/build.gradle:

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    implementation(name: 'md-toast-0.9.0', ext: 'aar')
}

d. Sync and Build:

Sync the project and rebuild.

Answer 2

Just for someone having the same problem, its related to OneSignal libraries importing. just read the latest onesignal documentation on adding it so the gradle and the error shall go away.

Answer 3

allprojects {
    repositories {
        jcenter()
        // Add this code block on your app
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}
