I'm working on a mobile application that takes a photo on a phone and sends it to another phone.
It should be able to work between an Android phone and an Iphone.
I'm working with phonegap.
First I was thinking of using the bluetooth technologies, but I read that it's impossible between android and Iphone.
So I was thinking of a UDP connection, but no matter what, I can't have a server and a client on my phone.
The only things that would work is to implement a server on my Computer.
Do you know another way of doing it ?
Nope. Thats the normal way of doing it - get a server on the internet and build a RESTFul api to listen for a device to send/receive to a phone. Android-to-Android, you could do NFC, but not with an iPHone

I try to find a way to get the phone's battery level from a watch wearable device.
Is there any way to get it from the standalone watch app?
Of course, it has a Bluetooth connection.
I want to know about 2 cases.
Phone: Android, Smart Watch: Android native wear 2.0 (kotlin or java)
Phone: Android, Smart Watch: Tizen Web App (javascript)
In neither case (Tizen nor Wear OS) is it possible to get phone battery information in the standalone watch app. You'll need to build a companion phone app and send this data yourself.

I want to establish communication between set top box and an android phone.
Is it better to use sockets or communicate via an embedded web server ?
1) An embedded web server can operate with any device having a browser, android devices included, with nice graphics/user interface. But it is heavier than solution 2.
2) Sockets is a lighter solution than a web server, but require an app (android) or a program (non-android) that know what to do and implement a user interface.
If the embedded web server is viable, probably is the easier solution.

I want to develop a mobile application (android OS), and I want to know how could I use a WIFI connection to connect 2 or more mobiles ..?, which protocols, which API's..?
Any help please..
In order to communicate, they first have to discover each other in the network. Link will help you do discover.
If you already know the IP addresses of each other, then the problem is much simpler. RPC call or HTTP call or use Sockets. There is this server which can take http calls on the android application. So, both the applications can have servers hosted.
I've just looked up this link.

I am writing an app to allow two android devices to play together. I'd like to know can I make a p2p connection with wifi between the two android devices without a third devices?
As long as you can target API level 14 and above you should be using the built in Wifi direct API's. Google has posted a very detailed guide on how to get WifiP2P working on Android.
Start from Device A - "Tethering and portable hotspot"
Connect Device B to created hotspot

I have 2 android devices and I need to communicate between the two using wifi to send and receive data. What is a reliable method to send/receive data over a private wifi signal, preferably without rooting (I already know how to do it if rooted, but I really don't want to root my phone (I'm rooting my tablet)).
I don't mind writing a lot of code myself, just looking for a method or class to send data and receive it over wifi, with examples.
Try to refer to the official Android developer site to learn more about the WIFI Direct API. This is the official documentation and you can attempt the demo to get started.
