How to get Callbacks from Chrome Tabs in android like web View provides shouldOverrideUrlLoading, onLoadResource, onPageFinished
you can only provide the following callbacks in chrome custom tabs:
/*** Sent when the tab has started loading a page.*/public static final int NAVIGATION_STARTED = 1;/*** Sent when the tab has finished loading a page.*/public static final int NAVIGATION_FINISHED = 2;/*** Sent when the tab couldn't finish loading due to a failure.*/public static final int NAVIGATION_FAILED = 3;/*** Sent when loading was aborted by a user action before it finishes like clicking on a link* or refreshing the page.*/public static final int NAVIGATION_ABORTED = 4;/*** Sent when the tab becomes visible.*/public static final int TAB_SHOWN = 5;/*** Sent when the tab becomes hidden.*/public static final int TAB_HIDDEN = 6;To attach a callback, bind to the custom tabs service as normal, and just pass your callback while calling newSession().
