 * This is Application class for Monochrome.
 *
 * You shouldn't add anything else in this file, this class is split off from
 * normal chrome in order to access Android system API through Android WebView
 * glue layer and have monochrome specific code.
 *
 * This class is NOT used by Trichrome. Do not add anything here which is only
 * related to Monochrome's minimum SDK level or APK packaging decisions, because
 * those are likely to apply to Trichrome as well - this must only be used for
 * things specific to functioning as a WebView implementation.
