What is the best way to support legacy methods that are being replaced by new ones?

Question

I like to use the findAll / findAllAsync method in android.webkit.WebView. findAll is deprecated, and Google suggests using findAllAsync, which requires a Jelly Bean or higher. However, I like my app for 2.2+ support. I tried to do the following, but I got a warning for findAll (deprecation) and an error for findAllAysnc (you need to increase the minimum version of the SDK):

      if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
          myWebView.findAll(query);         
      else
      {
          myWebView.findAllAsync(query);
      }

What is the best way to handle this? Should I just use findAll and ignore the failure warning?
