I'm looking for a QR generator for Android. I use Titanium and I need a module like this: qr encoder for iOS
I don't want to depend on thirds or in a website, I want to generate my own QR image for work offline.
Thank you for advance.
Tried these two modules I found on gitTio? Looks like they work both offline.

Hello can anyone provide me good plugin or sample for video player implementation in xamarin forms?
Req:
1) Player should have built in controller.
2) Should be able to show the video loading symbol
3) Video should have the video image with play button.
Can anyone help me pls?
This is the one that I use and it supports Video source from file as well as stream source. So far, this is the best I found for Xamarin forms.

Have a look at LibVLCSharp. Official VLC bindings for Xamarin/.NET.

MediaCapture gives poor quality of QR code image captured, because of which QR code decoder(Zxing) is not able to decode the QR code(Windows Phone 8.1 universal app)
The problem comes only if QR code becomes more complex, i.e. generated out of long string(more then 180 characters), for QR codes generated out of small strings(less then 180) it works fine.
If I feed image directly to Zxing decoder(copy qr image to solution and provide uri) it works fine. But if I capture image using mediacapture api await captureManager.CapturePhotoToStorageFileAsync(imgFormat, file);
and feed it to decoder it does not work,
By looking at the image you posted in the comments for the other answer in conjunction to the code snippets you're using for focus, I would guess that you're calling the focus API at the wrong time. Make sure to use the FocusControl (and other "auto" controls such as WhiteBalance and Exposure) after starting the preview.
Also, focus takes some time to converge, so make sure you're waiting for the operation to finish before capturing a photo.
Have a look at the CameraResolution SDK sample on the Microsoft Windows Universal Samples GitHub repo. You should be looking into using the GetAvailableMediaStreamProperties method, pick the resolution you want to use, and set it on the MediaStreamType of your choosing (Video, Photo, Preview) by using the SetMediaStreamPropertiesAsync method.
Do read through the full sample, though. There are some details (like the number of MediaStreamTypes supported by the camera, see VideoDeviceCharacteristic) that you should understand to build a robust camera app.
I am about to submit my app in iTunes connect.
Now it is asking me for screenshots for a 3.5-inch, 4-inch, 4.7-inch and 5.5-inch.
Since I coded it in swift I guess I can skip the 3.5inch part?
But my question is: I only have an 4-inch device available. How can I add the screenshots of the 4.7 and 6inch? maybe with the simulator?
Thank you
In the iOS Simulator File > Screenshot
That saves a screenshot to your desktop.
Simulator should be fine. You can edit it using Sketch, I found it really helpful.
I tried a few different methods, and what worked best for me in a short amount of time was to capture screenshots in the iOS Simulator at 100% scale and then resize them using GIMP, which is free unlike Sketch.
If you're in the business of creating screenshots for many devices, across locales or with frequent screenshot update needs it's best to look into automation with tool like Snapshot.
Trying to create a hello world android app with app inventor, and there's an option to get the barcode. I got it, now, what the heck do I do with it? what's the point?
Thanks!
It's a QR code, which encodes the URL of the app you've just made. That way you can download and install it.
See here for how to use it: http://sites.google.com/site/appinventorhelp/getting-started/first-app
You can open a barcode reader app on an Android device and point the camera at the barcode on your screen. I use "Barcode Scanner" but there are other options too.
Here is the standard answer given on the App Inventor forums
