Using startApp.getExtras() to retrieve vars if external app is already open in background?

[rolinger]

Using primary app to call/open a secondary app. In secondary app, retrieving params/vars with startApp.getExtras() works fine if the secondary app is not running. But how can I retrieve vars passed from the primary app if the secondary app is already running in the background?

$ionicPlatform.ready(function() {

    function onResume() {
      startApp.getExtras(function (inObj) {
        console.log("startApp getExtras called") ;
        console.log(inObj) ;
      }, function (fail) { /* fail */
          console.log(fail);
      });
    }
    onResume() ; 
   // calls function when app is ready
   // works fine if app is not running in the background
   // vars/params are successfully retrieved

    document.addEventListener("resume", onResume, false);  
    // listens for resuming app sitting in background
    // this triggers if app is in background and brought to the foregroun
    // it calls the onResume function, BUT, onResume doesn't retrieve vars/params
}

In the secondary app, the addEventListener works, it fires the onResume function when the app is brought to the foreground, however, it doesn't get the vars/params passed into it from the primary app.

On app resume, the console.log(inObj) does output the following object, but none of the vars passed in from Primary app:
{profile: "0" }

How can this be resolved?

You can add code in MainActivity.java

    @Override
    public void onNewIntent(Intent intent)
    {
        super.onNewIntent(intent);
        setIntent(intent);
    }

This allows the Android app to refresh the intent and receive new data
