I have developed a simple chat application where I am using the $window.onbeforeunload to notify other users when somebody closes the tab/browser (basically when the user leaves the room).

Here is my code

$scope.onExit = function() {
        $scope.chatstatus.$add({
            status: $scope.getUsername + ' left'    
        });
    };

    $window.onbeforeunload =  $scope.onExit;

This is working absolutely fine on desktop browsers but not on the Android Chrome browser. The onbeforeunload function is not getting triggered at all.

Please suggest a solution/workaround. Thanks.

EDIT: As mentioned in the comments that it is a known issue, kindly suggest a workaround if not the solution.
