Ionic-plugin-deeplinks issue, when app is in backround(Switched to someother app)

ionic-v1
1

I am using ionic-plugin-deeplinks for deeplinking, deeplink works properly when app is killed and started again . But it fails to route when the app is inactive(switched to some other app). My code structure is same as example shared on the plugin.

$cordovaDeeplinks.route({
’#/home/xyz’: {
target: ‘xyz’,
parent: ‘home’
}
}).subscribe(
function(match) {
}, function (nomatch) { //Since my url doesn’t match, i am handling the navigation on nomatch.
var loc = nomatch.$link.fragment;
$rootScope.$apply(function() {
$location.path(loc);
});
}
);

** i am using $location.path(loc) for the navigation . As i have few dynamic params on the url .

Observation:

  1. When an app starts ondevice ready event fires, then user kills the app.
    if user clicks on a apps link , the plugin opens the app properly and goes to the respective page.(Here onDevice ready will trigger and the deeplink observable serves the incoming deeplink).
  2. Afte step 1 When the app is switched , on pause triggers , now user clicks on an app link from gmail , here plugin opens the app , and the “onResume” event is called .
    Question: Will the same ondeviceready .subscribe() will serve the same scenario ?? In my case it doesn’t happen . And it never works on all subsequent pause/resume(flip app and comeback to app again).
    To handle this I have added the same code snippet on the onResume block :

Now the behaviour is as below:

  1. an app starts, ondevice ready event fires, then user kills the app.
  2. user clicked a link from Gmail and app opened.
  3. Now switch the app and click the link again - failed----(this is the only case where it fails)
  4. Repeat the step-3 -passed - Worked fine
  5. Repeat the step-3 - passed - Worked fine

Debugging further , following is finding :
On device ready : The observer on my app , is called before the deeplink object is created on plugin
On Resume : The observer on my app is called after the deeplink object is created on plugin .

To fix this , now i have changed my ondevice ready code as below and removed the deeplink code from onresume. So now i don’t see any issue .
Is it correct way of solving the discussed case ??

   //outside onready
  function subscribe_deeplink(){
       $cordovaDeeplinks.route({
            '#/home/xyz': {
                target: 'xyz',
                parent: 'home'
            }
        }).subscribe(
            function(match) {
            }, function (nomatch) {
                $rootScope.isNavigated = true;
                var loc = nomatch.$link.fragment;
                subscribe_deeplink();
                $rootScope.$apply(function() {
                    $location.path(loc);
                });
            }
        );
    }

   //inside onready
     $cordovaDeeplinks.route({
            '#/home/xyz': {
                target: 'xyz',
                parent: 'home'
            }
        }).subscribe(
            function(match) {
            }, function (nomatch) {
                $rootScope.isNavigated = true;
                var loc = nomatch.$link.fragment;
                subscribe_deeplink();
                $rootScope.$apply(function() {
                    $location.path(loc);
                });
            }
        );
