hi, Web Widget has a parent web app.... try to communicate with that app from companion app. And pass the value from web app to web widget. 

hi,

good idea. But where can I find information on writing a parent web app ?

I can't find info anywhere.

If you mean in the same wgt , using the index.html on parent directory of widget, I can write a web app there. But in any case my config.xml includes the master-app information and it should ask for installing the master app. It didn't when I tried the widget. (?)

ok. I got that.

And I tried to do an app with widget now. It is working.

However, I couldn't figure out how to pass variables between the parent app and the widget.

Is it documented somewhere ?

and the ide is throwing an error for the following widget configuration in config.xml

What may be wrong here ?

    <tizen:app-widget id="afgc92eoOp.testapp.testwidget" primary="true">
        <tizen:widget-label>Test Widget</tizen:widget-label>
        <tizen:widget-content src="widget/testwidget/index.html">
            <tizen:widget-size preview="widget/testwidget/preview.png">2x2</tizen:widget-size>
        </tizen:widget-content>
    </tizen:app-widget>

it says :

Invalid content was found starting with element 'tizen:widget-label'. One of '{"http://tizen.org/ns/widgets":box-label}' is 
 expected.

in fact here:

https://developer.tizen.org/development/guides/web-application/application-management/applications/widget-application#comm_host

it says that web widget can communicate with Android host app. So a parent app is not required in my case.

But when I do as described under section "Communicating with a Host Application on a Host Device" , my widget does not connect to the Android host and retrieve data.

There's just one point that I am unable to do:

the document on that page says that I should add priviledge:

    <tizen:privilege name="http://developer.samsung.com/privilege/accessoryprotocol"/>

in my app, I have the line

    <tizen:privilege name="http://developer.samsung.com/tizen/privilege/accessoryprotocol"/>

in config.xml (parent)

and when I try to add

    <tizen:privilege name="http://developer.samsung.com/privilege/accessoryprotocol"/>

I get a signature error installing the app.

So I am not sure which one is correct. 

Btw, should I use a config.xml separate for the widget ?

now the situation:

I need to get some information to my widget from the host app on Android mobile.

My initial method was to directly get info from the Android app to the Widget.

But I couldn't do it as I wrote in my previous post (I don't know why it doesn't work)

So, I am trying the other method as suggested in this thread by Iqbal Hossain

Android companion -> SAP-> Tizen Web App (parent) -> Tizen Web widget

In this method, the parent app gets the data. 

And I finally managed to get it from the parent to the widget using preferences API.

But , I couldn't figure out how to do it continuously. How can I make the parent app run in background when I open/use the widget ?

Is there a way to call parent app in background (shouldn't open in front of the widget) when the widget is selected (using visibility listener)  ? 

Btw, I prefer to use direct (Android to Widget) communication if that is possible.  Any ideas on that ?

These are the documentation I found so far:

https://developer.tizen.org/development/api-references/web-application?redirect=/dev-guide/latest/org.tizen.web.apireference/html/w3c_api/w3c_api_w.html#widget

https://developer.tizen.org/development/guides/web-application/application-management/application-preferences

https://developer.tizen.org/development/guides/web-application/application-management/application-information-and-controls/widget-information

isn't there anyone who has similar experience ?

thanks

Hi mekabe remain,

About continuously getting preference data, would you please have a look into Monitoring Preference Value Changes section in this link?
