title: Issue with appcompat-v7 and NotificationManagerCompat
body: <p>I'm trying to use</p>
  
  <pre><code>NotificationManagerCompat.from(this).areNotificationsEnabled()
  </code></pre>
  
  <p>to determine if Push Notifications are allowed for my app or not. However it does not compile with this error:</p>
  
  <pre><code>error: cannot find symbol
  Log.d(TAG, "Allowed PushNotes: " + NotificationManagerCompat.from(this).areNotificationsEnabled());
                                                                           ^
  symbol:   method areNotificationsEnabled()
  location: class NotificationManagerCompat
  </code></pre>
  
  <p>It's imported like this:</p>
  
  <pre><code>import android.support.v4.app.NotificationManagerCompat;
  </code></pre>
  
  <p>These are the parts of the build.gradle relevant for this I guess:</p>
  
  <pre><code>android {
      compileSdkVersion 23
      buildToolsVersion "23.0.1"
  
      defaultConfig {
          applicationId "com.example"
          minSdkVersion 16
          targetSdkVersion 22
          versionCode 10
          versionName "1.9"
          ndk {
              abiFilters "armeabi-v7a", "x86"
          }
          renderscriptTargetApi 23
          renderscriptSupportModeEnabled true        
      }
  </code></pre>
  
  <p>And this is the dependency:</p>
  
  <pre><code>dependencies {
    compile "com.android.support:appcompat-v7:23.4.0"
  </code></pre>
