Adding twitter-kit to android studio project

You need to add Fabric at the top of your build.gradle - you probably already have the apply plugin: 'com.android.application' line, just put all of this stuff in its place.

buildscript {
  repositories {
    maven { url 'https://maven.fabric.io/repo' }
  }
  dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
  }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
repositories {
  maven { url 'https://maven.fabric.io/repo' }
}

But this is just one hurdle - next you're going to have to authenticate to Fabric itself. Basically, you started in the wrong place - Twitter wants you to start by going to https://get.fabric.io/ and integrating Fabric into your workflow.

Complete Twitter integration is here. Follow the instructions. And ENJooooooY..
