title: How to change build tools version in Android Studio
body: <p>I have a problem using <a href="https://github.com/jfeinstein10/SlidingMenu" rel="noreferrer">jfeinstein10 Sliding Menu</a></p>
  
  <p>I added the library into my root project folder. But I get this error :</p>
  
  <blockquote>
    <p>Error:The SDK Build Tools revision (17.0.0) is too low for project
    ':SlidingMenu'. Minimum required is 19.1.0</p>
  </blockquote>
  
  <p>But I'm already using "19.1.0" but it still says I'm using 17.0.0</p>
  
  <p>Here is my build.gradle</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 22
      buildToolsVersion "19.1.0"
  
      defaultConfig {
          applicationId "com.repliklernet.replikler"
          minSdkVersion 14
          targetSdkVersion 22
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:22.2.1'
      compile group:'com.squareup.picasso', name:'picasso', version:'2.5.0'
      compile project(':SlidingMenu')
  }
  </code></pre>
  
  <p>What am I missing ?</p>
