Tizen 4.0 Web app privileges are broken

Galaxy Watch for Tizen Tizen Web APIs
1

Privileges work different in different projects.

Environment details:
Galaxy Watch Active 2 SM-R820
Tizen 4.0.0.7
Wearable v4.0 Web Application

How to reproduce:

  1. Create BasicUI and TAUBasic projects in Tizen Studio 3.7
  2. Add following privileges in config.xml for both projects:
    <tizen:privilege name=“http://tizen.org/privilege/bluetooth”/>
    <tizen:privilege name=“http://tizen.org/privilege/healthinfo”/>
  3. Add following code in the app.js for TAUBasic and main.js for BasicUI projects.
    var adapter = tizen.bluetooth.getDefaultAdapter();
    tizen.humanactivitymonitor.start(‘HRM’, function a(b) {}, function c(d) {});
  4. Run in debug mode on Galaxy Watch Active 2

BasicUI project throws WebAPIException “Permission denied” on humanactivitymonitor start, but successfully runs bluetooth.
TAUBasic throws the same exception (WebAPIException “Permission denied”) on the bluetooth line, but successfully starts humanactivitymonitor.

Is it possible to get both privileges in Tizen Web project?

Hi,
Please check the below code,

function onSuccess() {

    function onchangedCB(hrmInfo) {
        console.log(‘heart rate:’ + hrmInfo.heartRate);
        tizen.humanactivitymonitor.stop('HRM');
    }
    tizen.humanactivitymonitor.start('HRM', onchangedCB);
}

function onError(e) {
    console.log("error " + JSON.stringify(e));
}
tizen.ppm.requestPermission("http://tizen.org/privilege/healthinfo",onSuccess, onError);

Before Tizen 4.0, the pop-up requesting the user’s consent to use privacy-related privileges was triggered by first access to protected resources or functionality. Since Tizen 4.0, you can decide the moment in the application life-cycle when permissions are granted.

@Iqbal In my case the ppm property under tizen object (tizen.ppm) is undefined.
I get this error in console: TypeError: Cannot read property 'requestPermission' of undefined
This is the call:

tizen.ppm.requestPermission(uri,
	      function(success) { resolve(success); },
	      function(error) { reject(error); });
	  });

I am having the same problem did you manage to fix it?

No, not really, I couldn’t find a way to get voice control permission using Web or Xamarin apps for TV.
