Peer-to-Peer Communication HolePunching (Android)

由 淺唱寂寞╮ 提交于 2019-12-13 19:50:42
问题 I am working on an app that uses peer-to-peer communication between Android devices. It receives and delivers JSON data and the data never goes through the server ever. The server is only used to keep track of user IDs, login times, IP changes, and other stuff. This app will use sockets for communication. Requirements JSON data goes directly to an Android device from another Android device without going through server. The android devices can be connected to any kind network like 3G or Wi-Fi

问题 I am new to android, please tell me if inputMethodService can work with wifi p2p service discovery? I want one phone to act as a keyboard for another phone. Please tell me if it is possible and which resources to refer in order to begin with it.

问题 so I have created two separate apps, one acts as a client & the other acts as a server. Both devices are connected using hotspot: Connection between the devices is successful.

Change WiFi-Direct IP range? Force IPv6 in Android WiFi-Direct?

由 一笑奈何 提交于 2019-12-07 10:21:00
问题 I have two Android KitKat phones, both are running WiFi-Direct groups as Group Owners, let's call them GO1 and GO2 I managed to connect GO1 as a legacy client to GO2 without breaking any of the (previously set) wifi-direct groups. The problem is that, as you might know, the GO IP address is hardcoded in Android source, and is set to 192.168.49.1 Therefore, both of my devices, GO1 and GO2 have the same IP address (**)... each on his local network. My app is both client and server at the same

WiFi Direct device connection with other Android devices

由 扶醉桌前 提交于 2019-12-01 13:39:09
Can I connect a WiFi Direct enabled device to any other device which doesn't have WiFi Direct feature but supports WiFi hotspot connection? Does WiFi direct uses specialized hardware to be present on both devices? Will network discovery work in such cases? It is possible. Code taken from a talk I gave at Droidcon UK 2013. You need to call the createGroup(WifiP2pManager.Channel c, WifiP2pManager.ActionListener listener) method of the WifiP2pManager class. This will create a Wi-Fi Direct group that supports legacy Wi-Fi connections. Prior to the call, you need to register a broadcast receiver
