Does anyone know if it's possible for a Chrome extension to interact with a PWA? Since a PWA installed by Chrome seems to be just a Chrome wrapper for the web application, perhaps Google still allows extensions to interact with the PWA.
I know you can work with beacons with a iOS app or Android app.
But you can work with a web app to?
(A website recognize a beacon and do something)
Unfortunately, the general answer is no. You need native components to detect Bluetooth beacons on both Android and iOS. The web browsers on both operating systems have no hooks to detect beacons via JavaScript or HTML.
Chrome OS does have Bluetooth bindings in its Chrome browser, which may allow you to build a web app on Chrome OS that does this. But this would really be a Chrome App not a general purpose web app.
The Chrome browser for iOS and Android also detects Eddystone-URL beacons, but it will not pass the detection info to a web app. Detections are sent to the user as a notification and tapping on that notification simply brings up a configured URL in the Chrome web browser. This does not allow any dynamic web app behavior based on beacon detections.
How do I stop scroll in background which has a overlay/pop up on it? I have disabled the scroll and its working fine on windows and android but the background scrolls in iOS.
No. There's no direct way or a Windows Store app to launch other apps. The only way is to launch files or URIs into the default handlers for those file types and protocols.
If this is a side-loaded enterprise app then it can use a brokered Windows Runtime Component to call desktop code, and that desktop code can then call desktop API to launch other apps. See Brokered Windows Runtime Components for side-loaded Windows Store apps
I'm trying to integrate U2F Authentication in GWT project and I need to know if is this solution compatible with all new web browsers (Firefox, Internet Explorer, Safari...)? Normally in Google Chrome I've to install a plugin that's called "FIDO U2F (Universal 2nd Factor) extension".
Is the same for others browsers?
Is there any way to work without a plugin for new web browser?
Do other browsers support U2F? currently not.
Is there any way to work without a plugin for a new web browser? No, that's the whole point of U2F: a phishing attack is made impossible thanks to direct communication with the browser.
Extra information
You had to install a plugin in Chrome in the past, currently (I think starting from version 40), this is not required anymore: U2F capability is built in from that version on in Chrome. As to which other browsers support U2F: currently none. Firefox supports U2F via the U2F Support Add-on, and is working on supporting U2F natively.
Microsoft reportedly will include FIDO support in Windows 10. It might be possible that browsers will rely on the OS-U2F-check then, and do not (need to) include FIDO support directly anymore. However, this is speculation only for the moment.
An easy compatibility check I'd like to carry out is to use the Yubikey's demo site.. It will be reported immediately when your browser does not support U2F (try opening the demosite in Firefox and see what happens).
Yes, it is an old thread, but let's make an update:
2016 September update : FIDO U2F browser support
Chrome for Windows, OS X and Linux: Yes (Built-in)
Chrome for Android [for FIDO U2F over NFC and over BLE devices]: Yes (You still have to download the official Google Authenticator App but this requirement will disappear in the future)
Firefox: Devs are now officially working on it. Mozilla Foundation joined the FIDO Alliance. For now, while waiting for the official built-in support, you can use this great addon: https://addons.mozilla.org/en-US/firefox/addon/u2f-support-add-on/ (It won't work on websites that do not know Firefox can be used too...)
Safari, Internet Explorer and Edge: No U2F support is even planned, but who cares anyway... :)
Just for the record: Opera Public Beta (v41) has U2F built-in support too. The next stable release should support FIDO U2F too.
Google Chrome: out-the-box since Chrome 41 (no extension required) https://support.google.com/accounts/answer/6103523?hl=en
Internet Explorer: "in development" https://dev.modern.ie/platform/status/fido20webapis/
Mozilla Firefox: popular feature request https://bugzilla.mozilla.org/show_bug.cgi?id=1065729
It isn't specifically true that browsers can't add compatibility via extensions as per Michael's post, the issue isn't that it's secure because the browser "directly communicates" - USB can be sniffed so U2F isn't secure in that sense, which is precisely why it has defences against replay attacks.
The issue relates to browsers not generally having support internally to directly talk to USB devices - or more usefully for extensions to do that (but that would throw up other unrelated security concerns). It's perfectly plausible for a piece of software to act as an intermediary for an extension and pass on authentication events to a FIDO device; I've investigated the possibility and it absolutely would work without harming the security of U2F itself - native browser support would be preferable though.
We are developing an app with Sencha Touch 2 and PhoneGap 2.0. We also want to use WebGL.
But neither the android browser nor safari mobile supports it.
However Opera Mobile 12 supports WebGL. Is it possible to start the sencha app with Opera Mobile?
Firstly, PhoneGap overrides the capability of Native Android browser. We cannot use the Opera Mobile browser features for developing the PhoneGap Applications.
Secondly, Sencha Touch is not supported by Opera Mobile. It runs only on WebKit browsers. I am not sure about Mobile chrome. But any other browser except android default browser will not able to run all features of sencha.
Hope you got your answer.
You can try RhoElements v1 browser. It also only supports WebKit as far as I know.
