Great video as always! I would like to ask something else: is there a way to get real time flow of data-samples from the microphone? I would like to apply real time digital filtering on voice and then send the filtered flow to the speaker.

[@TheCodingBus]

Thanks. Yes possible but problem is that there is some limitation in google speech we need to wait some seconds for there response or once he is speaking we can't speak etc.

Great video. I have a question about something else. My app has push notifications extension. I coded it in a way that i can send updates about the app but the notifications don't show until i open the app. Is there a way to run the app in background ?

Thanks for the video... I have a problem with the code, the error says that I have to specify a WebViewer using the WebViewer designer property before I can call Toggle Camera FacingMode... Can you help me???

[@TheCodingBus]

Most Welcome, ya sure, so click on the extension then right click on the dropdown option where u need to select the browser. make sure drag and drop the browser before doing this on design
