      <description>&lt;P&gt;&lt;A href="https://www.dropbox.com/developers/documentation/http/documentation#oauth2-authorize" target="_self"&gt;The&amp;nbsp;Dropbox OAuth app authorization page should only be processed in the user's system browser&lt;/A&gt;. Using a web view is not officially supported, so I'm afraid I can't offer help with this.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;That said, Android 4.4.2 itself is relatively old and&amp;nbsp;I believe is itself no longer officially supported by Google, so you may want to look into upgrading to a newer version. Or, at least upgrading the version of Chromium used in your webview, if possible, as that may help with the issue.&lt;/P&gt;</description>
