title: android ContextCompat.checkSelfPermission() not found
body: <p>I am trying to make runtime permissions backward compatible with older devices but using the support library i cant find <code>checkSelfPermission()</code> static call in <code>ContextCompat</code> class, but its documented <a href="http://developer.android.com/reference/android/support/v4/content/ContextCompat.html#checkSelfPermission(android.content.Context,%20java.lang.String)">here</a></p>
  
  <p>Here is my project gradle settings:</p>
  
  <pre><code>defaultConfig {
      applicationId "org.myprogram.cool"
      minSdkVersion 16
      targetSdkVersion 23
      versionCode 39
      versionName "3.0"
  }
  </code></pre>
  
  <p>and here is the dependencies:</p>
  
  <pre><code>compile 'com.google.android.gms:play-services:+'
  compile 'com.squareup:otto:1.3.5'
  compile 'com.android.support:appcompat-v7:22.1.1'
  </code></pre>
  
  <p>any idea what i am missing ?</p>
