/**
* This sample demonstrates how clickable links can be added to a
* {@link android.widget.TextView}.
*
* <p>This can be done in three ways:
* <ul>
* <li><b>Automatically:</b> Text added to a TextView can automatically be linkified by enabling
* autoLinking. In XML, use the android:autoLink property, programatically call
* {@link android.widget.TextView#setAutoLinkMask(int)} using an option from
* {@link android.text.util.Linkify}</li>
*
* <li><b>Parsing a String as HTML:</b> See {@link android.text.Html#fromHtml(String)})</li>
*
* <li><b>Manually by constructing a {@link android.text.SpannableString}:</b> Consisting of
* {@link android.text.style.StyleSpan} and {@link android.text.style.URLSpan} objects that
* are contained within a {@link android.text.SpannableString}</li>
* </ul></p>
