Background job (applicationDidEnterBackground)

[mystere13]

Hi,

Is there an iOS applicationDidEnterBackground() alternative for Sencha?

I need my app to do some job and polling while it's in background

Thank you

Jo

You can use phonegap for that.

Hi, not in Sencha but in Phonegap you can use the pause and resume events:

Somebody has an example sending an alert while app is paused?

I loaded cordova-2.2.0.js, added onPause() method in my index.html, tried to lauch some alert() or Ext.device.Notification.... no success...

Put this in your app.js launch function:

var onPause = function(){
       alert();
}
document.addEventListener("pause", onPause, false);

"resume" ?

Oops sorry, I copied that from my code and forgot to change the event name. I've edited the post now.

Is it possible to do something like that? It's showing me nothing

launch: function() {
        var onPause = function(){
            alert("onPause");
            Ext.device.Notification.show({
                title: 'onPause',
                message: 'onPause',
                buttons: Ext.MessageBox.OKCANCEL,
                callback: function(button) {
                    if (button == "ok") {
                        console.log('Verified');
                    } else {
                        console.log('Nope.');
                    }
                }
            });
        }
        document.addEventListener("pause", onPause, false);


        // Destroy the #appLoadingIndicator element
        Ext.fly('appLoadingIndicator').destroy();
        // Initialize the main view
        Ext.Viewport.add(Ext.create('App.view.Main'));
}

That alert did show for me when I used your code exactly as it is, but once I reached the Ext.device.Notification code, I received an error in logcat, I consequently found a typo in the Sencha library, tut!

First, make sure you require the following in your app.js:

'Ext.device.Device',
'Ext.device.Notification',
'Ext.MessageBox'.


If you're using Sencha Touch v2.1 like I am (You can check your version by typing Ext.getVersion() in the console) ..

In your folder structure, go to:

touch/src/device/notification/PhoneGap.js

On line 18 for me, it read:

var ln = butons.length;

Which is wrong, there is a typo, it should read:

var ln = buttons.length;

Try that.

It seems that the typo has been resolved in 2.2.0 Alpha.
