title: Adding dependency in Android Studio fails
body: <p>It's my first time adding a custom library in Android Studio and I can't seem to get it to work. I'm trying to use this library. <a href="https://github.com/lewisjdeane/L-Dialogs" rel="nofollow noreferrer">https://github.com/lewisjdeane/L-Dialogs</a> And it's instructions are simple enough. Drop the .aar file in the libs folder and add this to the build.gradle file</p>
  
  <pre><code>dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'uk.me.lewisdeane.ldialogs:RENAMED_FILE_NAME_HERE@aar'
  }
  
  repositories{
      flatDir{
          dirs 'libs'
      }
  }
  </code></pre>
  
  <p>but I keep on getting "Error:Failed to find: uk.me.lewisdeane.ldialogs:ldialogs:"</p>
  
  <p>Here's a picture of my project structure and what not <img src="https://i.stack.imgur.com/Jovt5.png" alt="Project Setup"></p>
  
  <p>And here's my build.gradle file </p>
  
  <pre><code>    apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 20
      buildToolsVersion "20.0.0"
  
      defaultConfig {
          applicationId "com.oxpheen.notes"
          minSdkVersion 13
          targetSdkVersion 20
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:20.0.0'
      compile 'uk.me.lewisdeane.ldialogs:ldialogs@aar'
  }
  
  repositories{
      flatDir{
