      * Unfortunately, most browsers on Android, e.g. chrome, reload the URL when a browser
      * tab is activated.  As a result, chromoting is launched unintentionally when the user restarts
      * chrome or closes other tabs that causes the redirect URL to become the topmost tab.
      *
      * To solve the problem, the redirect intent-filter is declared in a separate activity,
      * |OAuthRedirectActivity| instead of the MainActivity.  In this way, we can disable it,
      * together with its intent filter, by default. |OAuthRedirectActivity| is only enabled when
      * there is a pending token fetch request.
