title: Android 4.2.2 alternative webview
body: <p>I'm working on a custom Android device running Android 4.2.2.</p>
  
  <p>We have a lot of troubles with the default webkit webview not behaving as it should (Failing some javascript etc.) and performing very poorly. </p>
  
  <p>All these issues are fixed on our phones webview running on Android 4.4.</p>
  
  <p>Is there an alternative way to use the new chromium backed webview from Android 4.4 on my 4.2.2 build ? (I'm building AOSP 4.2.2 from source)</p>
  
  <p>If not, is there some alternative webview that I could test, which perhaps fixes some/most of our javascript/performance issues?</p>
