I want to know what channel users is viewing using my apps, to display related real-time information.
Does it support and allow us to do that?
You can use Window plugin from SEF plugin API. There is GetCurrentChannel_Name function to get channel name.
You can also use TV plugin - there is information about program.

Please I want to create an online or offline feature for users in my app
I tried onDisconnect in Firebase and it didn't work for me
You can use socket.io for flutter. When user open the app then socket will tell the server that specific user is connected.The user able to see other connected users. Here is a article of how to use socket.io in your project.
You can try pusher presence channels.
It is based on websockets, and it tells you who is connected to the channel (who is present). You can find the use cases for presence channels here.
click here to find out how to build presence channels.
I'm currently building an online and offline statusbar for a flutter app if a user is connected to a presence channel. If I have the working code I'll post an update.
Can PWA access contacts, gps or use the phone camera?
Is this possible in any system (ios, android) ?
Is there any plan in development to implement any of these features ?
There are some restrictions that cannot be overcome with a PWA:
- you cannot access the contacts list on a phone. - On the other hand, you can take photos and use GPS location.
On whatwebcando.today web site you can have a list of APIs available via browser compared to native apps. If you click on one feature, you can see a sample snippet showing how you can implement it and also details about the browsers support.
UPDATE 30.09.2019
From Chrome v77 there is a new experimental API available: Contact Picker
The Contact Picker API is an on-demand API that allows users to select entries from their contact list and share limited details of the selected entries with a website. It allows users to share only what they want, when they want.
For example, a web-based email client could use the Contact Picker API to select the recipient(s) of an email. A voice-over-IP app could look up which phone number to call.
Hence it might be that the the remaining PWA restrictions will be solved in a near future.
It depends on the device the PWA is running on.
Camera and audio seem to be universally supported. Contacts, on the other hand, seem to be inaccessible regardless of platform.
Other features, such as GPS and geolocation may vary from device to device.
A good way to find out what your browser is capable of (and thus your PWA - it runs in a web browser) is to go to https://whatwebcando.today with the browser you want to support. Try visiting it with an iPhone, Android or other device for a list of enabled features.
This list changes as browser and OS developers increase access to native features, so there's a good change that if it isn't available now, it will be in the future. However, it's important to be aware that some features such as access to the wider file system and hardware configuration are likely to remain sandboxed for security reasons.
I have a really simple game on both iOS and Android written in Unity and I would like to save user progress across devices/OSes.
I already have Facebook analytics in it and so i was thinking i can implement Facebook Login and just save a couple of numbers on the Facebook server.
Upon some research it seems (?) that Facebook doesn't offer anything like that. You have to set up your own server and then just identify the player with Facebook login. A server like that is really an overkill for the game as i just want to save a simple Level Passed number.
Is there any other way? Can i use Facebook like that to save ONE custom user property? Perhaps i can use Google Play Services (both iOS and Android (?) ) to achieve what i want?
Any other free way of saving user progress across devices?
First thing Google play service stopped support for IOS
https://developers.google.com/games/services/ios/quickstart
Other suggestion for Cross platform services like firebase cloud, photon, Gamesprak etc.
https://firebase.google.com/products/firestore/
https://www.photonengine.com/
https://www.gamesparks.com/
Please not most of them giving free service for development only. Before use please check its price details
Is there a way to programmatically list available input devices and allow to change the current one being used for the WebSpeech API?
I'm aware Chrome shows a video icon on the address bar where a device can be chosen, but I want to make this setting available on the web app itself.
Yes, there's a way- take a look at https://webaudiodemos.appspot.com/input/index.html, it lets the user select the input. PS: This works just for chrome.
Also you can look this example using webrtc, however I'm not sure if it can be integrated with webspeechapi: https://webrtc.github.io/samples/src/content/devices/input-output/
Also, take a look at this post: https://developers.google.com/web/updates/2015/10/media-devices It has a lot of information
Sorry to burst your buble but it can't be done, the only way to have access to the devices is using the system API's and the web browser limits your access to specific API's that he chooses to expose, unfortunately for you the device related ones are not exposed.
On a side note, think of the repercussions of exposing your devices to every website you visit...
I'm wondering if there's Google Apps API support for building a bot that lives in a Spreadsheet and interacts with users via the in-document chat features. I can't find a Google Apps API that defines calls to view and send messages for in-document chat, but I figured I'd ask in here case I'm missing anything!
If this doesn't exist, any suggestions about how I might build out this type of functionality?
I am fairly certain there is no official API for the in-document chat. I do know that the regular Google chat uses XMPP; the in-document chat probably just uses a more limited version.
In theory, I suppose Google should not be able to differentiate between a program and a user. You might be able to reverse-engineer the chat protocol by digging through the source or inspecting the network. You could also run a browser on your machine and simulate mouse and keyboard input, like a regular input.
Alternatively, you could interact with the user using the spreadsheet itself, via the Google Spreadsheet API.
