title: How to install Android SDK Build Tools on the command line?
body: <p>I want to setup the Android dev environment from command line, and encounter the following issue:</p>
  
  <pre><code>wget http://dl.google.com/android/android-sdk_r22.0.5-linux.tgz
  </code></pre>
  
  <p>after extract the file, run</p>
  
  <pre><code>tools/android update sdk --no-ui
  </code></pre>
  
  <p>However, it is too slow on running</p>
  
  <pre><code>Fetching https://dl-ssl.google.com/android/repository/addons_list-2.xml
  </code></pre>
  
  <p>The result is that nothing in folder build-tools, and I want is aapt and apkbuilder, since I want to build apk from command line without ant.</p>
