I just add google maven and jitpack maven repos in project (not app) build.gradle file like this:

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        maven {
            url "https://jitpack.io"
        }
    }
}

and it helps
you can see properly configuration in my project

import com.github.droibit.android.reactnative.customtabs.CustomTabsPackage;

Just add this at the top of your MainApplication.java file

If still not solved do the following.

@OverRide
protected List getPackages() {
return Arrays.asList(
...,
new CustomTabsPackage() // adding package
);
}

Add this if you're using latest react native version
packages.add( new CustomTabsPackage());
