Trying to acquire Tizen TV Web App permission - web

Question

I'm trying to build a POC Voice recognition app on the Tizen TV platform, but using Web application API I've failed at getting the permission for voice control.
Debug console prints: Cannot read property 'requestPermission' of undefined (in my case the global tizen object has no ppm property which in all examples on the Web should hold the requestPermission method).
function requestPermit(uri) {
return new Promise(function(resolve, reject) {
tizen.ppm.requestPermission(uri,
function(success) { resolve(success); },
function(error) { reject(error); });
});
}
var start = function() {
return requestPermit('http://tizen.org/privilege/voicecontrol.tts')
.then(function() { return init(); })
.catch(function(err) { return console.log(err); });
}
$(document).bind( 'pageinit', start );

Answer 1

As far as I know, the Privacy Privilege module of Web API is not supported on TV profile. There is no module Privacy Privilege on TV's docs here, so the behaviour you met is what I would expect - tizen.ppm is undefined.
Also basing on information here:
Since Tizen 4.0, the status of privacy-related privileges can be resolved at runtime using the Privacy Privilege API (in mobile and wearable applications).
There is no need to request a privilege on TV profile.
If you want to check in your code automatically, if the Privacy Privilege module is supported try:
if (tizen.systeminfo.getCapability("http://tizen.org/feature/security.privacy_privilege")) {
// ppm module is supported - you need to request privilege from the user here
} else {
// ppm module is not supported - just log or ignore, no consent from the user is needed
}
