I am looking for a way to control a wifi document scanner through an android application (that scans PDF files). The scanner model has not yet been chosen. It may also be an all-in-one printer.
I know that HP has an app that allows control of their all in one printers but I am looking for a way to integrate these functionalities to a custom app.
More specifically, these are the points for which I need light (that correspond to the approaches I have thought about):
Is there a standard protocol for communication with a wifi scanner (like IPP for printers)?
Is there a way to interact with an other app from which I don't have much documentation (send an intent or whatever)?
Is there a known alternative to a wi-fi scanner (like the Google Cloud Print)?
Thanks in advance for any hint that could help me in my search.
There is a library that can help. The http://roncemer.com/software-development/java-ocr/. Hope it helps.

I'm looking to create a Bluetooth Controller app (probably for android) with some specific features for a game I'm making, but I can't find any information on how these work.
Everything I search only comes up with recommendations for the best apps to use.
Here's what I need to know:
How do these things work?
What libraries could I use to create one of these
I don't really care what language or framework these are for, I'm willing to learn something new in able to make this

I wanna try to make an application like Discord (Groups/Add Friends/Voice Call/Video Call/Streaming) and until now I was focus on messages and on an application for Web(ReactJS or any) and PC/Mac/Linux(ElectronJS or any), and working on backend with NodeJS/ExpressJS/Socket.IO/GraphQL/MongoDB. Recently got a solution for Voice Call and Video Call which is PeerJS, but now I asked myself how would this work in Androd/iOS application? Am I choosing well my frameworks and language? Because of course one Android/iOS user have to be able to join to a Voice/Video with users on PC/Web Is there other frameworks? Not just for Voice/Video Call, all the application. Can anyone please share some documentation or tips?
Thanks
A personal tip would be to refrain from using PeerJS, as it doesn’t support VP8 Simulcast. When creating high-load group video calling software like discord, you need VP8 Simulcast because it splits a stream into different bitrates for different users, dependent on their bandwidth and that of the person streaming.
Consider reading about WebRTC in JS WebAPI! Unfortunately, the main issue nowadays is hosting a Signalling server (which essentially manages who is where in terms of rooms) and TURN Servers (which gets information such as the IP address of a user joining a room).
In terms of the iOS app, and Android App, consider implementing with a language of your choice, such as Xamarin.
Personally, I prefer React Native for mobile applications. Take a look at it online!
Good luck in your venture!
I have been trying to search a way to changes Wifi Hostspot name of android device using flutter. I also wanted to get a list of available wifi nearby using flutter. I have just started learning flutter and i dont have much knowledge to write plugins for it from scratch. Is there any easier way to perform above two things?
The 3rd-party wifi package might help you out with listing available networks. It supports Android, but not iOS.
For the hotspot situation, you can check out this (unpublished, only on github) package: wifi_iot. That one also mostly supports Android for most functions. You would need to test it yourself and extract which functions you need, because you can't get it through https://pub.dartlang.org/
I'm a complete newbie with regards to developing for Android, and for starters I'm trying to develop a simple card game that can be played multiplayer over a local network. I'm having trouble finding a starting point for how I would go about this, I can find plenty of things for communicating across the internet but not having much luck seeing how you communicate directly between two devices over a LAN.
It's a major part of my plan for this app that it be multi-platform and that iOS devices and Android devices can play against each other, so I'm looking for a method that supports this. I know it's possible as I can see there are other apps that have this functionality.
I don't need a detailed implementation (although the more help the better!) but if anyone could just point me in the right direction for how to go about something like this, I'd be really grateful.
I think u need a connection peer to peer, android implements Wifi Direct
Look android dev site. http://developer.android.com/guide/topics/connectivity/wifip2p.html
For a card game I recommend using client-server.
Electrotank is a good server that provides a framework that helps you create a game of this type, with rooms, chat, friends list and connect to Android and iOS. U can write server plugins in Java.

Another good server solution is SmartFox.
Or you can create a turn-based game, creating a database to save data and a counter on each client, where you will limit the time for each move, from this time you send data to the server and your opponent query this data the server.
I was working on the exact same thing. You'll want to use sockets to open up connections between multiple instances the same app.
I created an example app that demonstrates how to do this which I link to and explain in great detail here: http://brendaninnis.ca/connect-nearby-devices-part-2.html
I have an example for both Android and iOS that communicate with each other.
I want to ask you about some bluetooth library which I can use to implement simply application. I want to connect two devices by bluetooth. In application I want to have two buttons and I want to send from one device to second device by bluetooth which button was push. How I can do that? Any idea or tutorials can recommend me?
In the Android developer page there is a good Bluetooth chat example, with source code. Follow this link to download the Example.
Then I suggest you the following tutorials:
