I am working on a mobile application (Android)using application craft which is a web-based technology which can also be ported to an android app. I would like to know how is it possible to allow my system to activate the camera device in the mobile device so that the user is able to capture the QR code and the system is able to decode and display the details accordingly.
I am not intending to use the QR technology to navigate users to a link but use the technology to display details.
Hope someone can enlighten me.

I want to be able to enable a user on a video networking web platform to only need to grant camera permission one time, and be able to have separate video chats with multiple users.Part of the 'event" will have multiple one to one video chats. There is a one to one video chat with one user. it ends. there is another 1 to one video chat with another user. It ends, etc.... As it is this permission is needed to be granted for each separate video chat. I am having this issue primarily with ios on safari. I am having someone else build this web platform and the person is not able to solve this issue with the video plug in they are using. They claim it is an issue with mac devices that cannot grant permission to particular websites. But I know that this issue has been solved with other networking platforms. Can I accomplish this with tokbox (vonage)? Or please tell me what video platform to use and the specific way to accomplish this. I am not a developer but will pass on exactly what you give me to my developer team. I am considering having the website be rebuilt with tokbox but first want to be sure that I can accomplish this. The website it being built with PHP but this issue is so sognificant that I might have it bilt from scratch in whatever way is needed. Thank you very much!!!! I know this issue is solveable as I've seen this on other platforms - Zoom and other video networking platforms like remo.. thanks!!!
The Agora web SDK requests the browser for camera and microphone permissions. Now remembering these permissions is done by the browser itself and not the JavaScript SDK.
As to answer how other platforms offer this is because those are native apps and not a mobile website. So they don't have to play by the rules of the browser. If you are interested in that, you can take a look at our IOS SDK.

Hi I want to build an library automation but I want use QR code for books.
And I want to read QR code from mobile and could I do that from web application to read qr code from mobile and conver to form data after I can save information books. Is it possible . Or should I do hybrid-mobile-application later read QR code as mobile client .And which tech are opensource and fast like ZXing.If possible could I do all of them with javascript
Yes, you can read a QR code from a web application. There are javascript libraries that enable you to scan a QR code using a camera from a mobile phone. Here is one: https://github.com/jbialobr/JsQRScanner. This is a port of ZXing QRReader to javascript. Note that many browsers only allows you to use a webcam when your website is served via https.
I'm working on a location related project. I found that iOS has iBeacon which can help the app to get the location data. I want to know if iOS Safari does have the access to it? Or any other similar bluetooth device which can be accessed?
Not yet. There is a proposal in W3C for a "web-bluetooth" specification which has been partly implemented in the chrome , opera and chrome-for-android browsers, although they need to be activated by the users in a somewhat convoluted manner. Like all these things, it'll take time for the committees to spin their wheels and for the browser makers to decide if they want to support it , and then implement it.
MDN docs: https://developer.mozilla.org/en-US/docs/Web/API/Web_Bluetooth_API
Apple don't have this built in to Safari (yet), however there is a Web Browser app called WebBLE that implements 'Web Bluetooth' mentioned by Shayne.
Currently the app only supports a subset of the standard, but it's more than enough for most tasks. It's also Open Source so you could add it to a WebView in your own app if needed.
Having said all that, currently I don't believe Web Bluetooth supports accessing Advertising data - so while you can connect to Bluetooth LE devices and interact with them, you may not be able to get the actual Advertisements (which is kind of the point of iBeacon).
So I asked this question... stripe.js magenetic card reader php
I have a PHP POS app which can be access from the central location view a browsers, all data can be entered and its works well. Looking to make it more mobile with the use of a audio jack card reader for iPad / iPhone (similar to square). The problem is I do not want to make a separate native app. If I was to run the app in a WebView based iOS app would it be possible to interact with the audio jack and get the data to put into the Stripe payment transaction?
Hopefully that not too vague. Will try my best to explain further if needed.
Thanks
Not possible with just webviews. Native side of your app should interact with hardware.
It is not possibile. But, you can develope an iOS app that interact with audio and that have a webview inside.
I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls. The app would allow the user to enter a mode where the microphone was live and listened for predefined keywords like 'down', 'up', 'next', 'back', 'home', etc.
I don't want to reinvent the wheel on this so I'm just wondering first, if someone has done this already and if not, are there any good tutorials or SDKs available to help with recording someone's voice, and then comparing future output to see if it matches, or just dealing with the microphone in general?
Let's put aside that this is a fairly vaguely worded question for the moment.
If you are expecting to allow voice control in your app that somehow works throughout the entire device, it's just not possible. Your app would only work to control itself -- or at least itself and whatever external hooks you can normally get to the rest of the device, like, say, playing a song out of the user's iTunes library.
If you're planning on doing this in a jailbroken environment, then you should find some open-source library that does voice recognition -- if there are any -- and start from there. Be prepared for a very long haul, though.
Dragon Mobile SDK is what you're looking for.

There maybe others voice recognition SDKs out there, but this is the only one I can think of from the top of my head.
You can find a library called CMU Sphinx. There's an iphone version for it called
PocketSphinx. See if it fits your needs.
I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls.
The iOS 13 new feature Voice Control fully meets your request because you can control your device and your app with your voice exactly the same as with touches.
It's also possible to define actions for some specific words for instance.
The device settings are perfectly well detailed to handle this amazing new feature (Accessibility - Voice Control):
If you need dedicated names to be read out in your app, use the accessibilityUserInputLabels property to define them.
That's definitely the built-in tool your need to reach your goal: no need to use external library or SDK, everything is natively provided. ;o)
