I have finally solved the problem .I have created a new Empty project and re-written the code by following the Sender App tutorial (Link):
MainActivity.java

Log.d(TAG, "Connected to "+ route.getName());

Toast.makeText(getApplicationContext(), "Connected to "+route.getName(),Toast.LENGTH_LONG).show();

mediaRouter.addCallback(mediaRouteSelector,mMediaRouterCallback,MediaRouter.CALLBACK_FLAG_PERFORM_ACTIVE_SCAN);
}
@Override
protected void onPause() {
super.onPause();
Log.d(TAG, "onPause");
if(isFinishing())
{
mediaRouter.removeCallback(mMediaRouterCallback);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
MenuItem media_route_menu_item = menu.findItem(R.id.media_route_menu_item);
MediaRouteActionProvider provider = (MediaRouteActionProvider) MenuItemCompat.getActionProvider(media_route_menu_item);
provider.setRouteSelector(mediaRouteSelector);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
/*
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
*/
return super.onOptionsItemSelected(item);
}
}
And now it works properly. The Icon is now available and I can connect to my Chromecast. I am not sure but I think the problem was about the Instance of MediaRouter.Callback;
PS: I have uploaded the full code on GitHub . You can check it out. (Link)
