Resource Synchronization

Resource synchronization or SYNC is a an option that allows you instantly update live applications without uploading a new binary on the Store. 

To benefit from this option you need to enable SYNC before you request the binary to upload on the Store. On the last step of submission process enable(if not) SYNC to use this option within the application.

Note: SYNC option is enabled by default for app.xml

Publish the application on iTunes Connect, Google Play Store or Amazon Store. Once the application is approved you can use Resource Synchronization to update the existing files(images, sounds, HTML files, etc.). 

You can show or hidden SYNC option from App Settings -> In-App Settings option.

To choose what files do you want to sync, go to app's Dashboard -> Edit Pages -> Resource Manages. The check-box on the far right of the appeared table represents the sync feature state of the file (page).

Note: Just files set as SYNC in Resource Manager will be updated.

When user taps on Setting button -> SYNC, selected files will update from the server. Also, each time the user opens the app the files will update automatically.

This is a great resource and I use it quite often.

I've had a couple situations where I wanted to update a page on an existing app, but the snyc box was not checked for that file.

In that case, can I go to the resource box, check the snyc box, and at that point will my changed file get updated?

In other words, if I forget to check the sync box, can I do it after the app is published?

Generally if you forget to check the sync box you can do it after the app is published.
(All settings are saved in the app.xml file and sync is enabled by default for it).

Cool. Thanks,

So far i understand it i can synchronize files that already exist in my released app or can I this way synchronize new created files & pictures - icons?

Yes, you can sync new files. Just make sure sync option is enabled for these files.

I want to ask about sync function. Let's say if I make a html page (for club events), and I want it to be updated everytime user opens the app, do I necessarily need to have a top bar with a sync button or can I choose to not include it, but leave sync fuction enabled and it will update automatically? If that is true, how often will it sync?

Hello Simas,

The sync button is used for manual syncing.
If you want your app to be updated automatically, just enable the sync feature at the submission process and your app will be updated every time when user will open it.

I have following query about sync: 

If I enable sync function and if my app user doesn't have internet connection then what will happen. Old version of app still work on his/her device or will not work till user sync it like your live demo. Your live demo always need internet connection. 

Please give reply as soon as possible 

The app will work.

Regarding sync feature:

1) Can I take a menu page which links off to a page on the internet and add menu items to that page during sync and remove others? It is on one "page"

2) Will syncing also allow me to add an item to a menu page and add a page on the app as the target for that menu item. In this case we are really adding a page not changing information on a page.

Thank you,

1) Yes.

2) Yes.

How long do the files selected for sync take?  I've been hitting "sync" on my phone after installing the app and nothing has gone thru?

I just select the files and click "done"....that's it? Then the user has to hit their sync button (which I've done) and nothing is changing.


If you have issues with the resource synchronization feature please open a support ticket and we'll investigate. All is working as expected for me.

Best regards,

I would like to ask what most developers do?

I usually leave my Apps to autosync but if there is no internet then it pauses maybe 20-30 seconds on my bigger Apps and anything over 5-10 seconds and people these days will give up....

In the app submission process you may check this.
