title: Android Lint error: Class requires API level 3, current is min is 1
body: <p>When running my Android app I often get a list of errors, wich says </p>
  
  <pre><code>Class requires API level 3 (current min is 1): android.hardware.SensorEventListener
  </code></pre>
  
  <p>I've searched for the correct answer to this, like Android tools > Clear Link Markers, but this doesn't solve the problem. Every once in a while the list of errors keeps coming back. Is it something in my project settings or are my methods deprecated? I've installed the latest SDK for Android 4.4. </p>
