wifi-direct

问题 That's an easy question, I've to get the "Group Owner address" using "Wifi direct", I know that this is in WifiP2pInfo.GroupOwnerAddress, but how can I initialize WifiP2pInfo.groupOnwerAddress to get the Group Owner address in my application? Could someone give me a pass to pass? I'm new in android and java. Many Thanks. 回答1: NetworkInfo networkInfo = (NetworkInfo)intent.getParcelableExtra(extraKey); if (networkInfo.isConnected()) { wifiP2pManager.requestConnectionInfo(wifiDirectChannel, new

问题 I'm currently developing an application where I need to create a link (read: WiFi link ) between a desktop app (on Windows 10) and a tablet (Android, but it is irrelevant). Workflow: Push button -> elevate privileges if required -> Create hosted network-like WiFi network -> Allow device to connect providing a SSID/password/dynamic IP address ... Previously, I used a system call to netsh (running the app with elevated privileges) to create a hosted network. Now it seems it is less and less

问题 I am trying to figure out how to make game which will work only locally using Wifi Direct without any internet access. The concept is very simple. It will be some kind of presentation so I need to have one master/host device and other connected devices will be slaves/clients . When I press button on master/host than should be changed only one value (string or int) in all slaves/clients devices. With support of 20-40 connected devices in same time. I have Tried: UNet - it works only if it is

问题 How can I search for Miracast compatible devices (may be using WiFi Direct) in android? I just got to know that DisplayManager and Presentation class in Android 4.2 help in presentation & miracast. But is there any way I can check if the other device is Miracast compatible / search Miracast sink? Thanks Smitha 回答1: android framework source codes shows how to search miracast sink devices. basically using WiFi Direct devices search API, discoverPeers -> requestPeers -> isWifiDisplay &

问题 I started creating an Android app wifi Wifi direct functionality. I do a peer discover and I like to see the peers in a listview. I now have a app which tries to discover peers and shows the peers in a list. But I'm facing the problem that this works fine on my Android 5 device. Here I can see my Android 8 device, but not the other way around. I cannot see my Android 5 device on my Android 8 device. I followed steps from here: https://developer.android.com/training/connect-devices-wirelessly

问题 I am trying to retrieve the MAC address of an Android device. This is ordinarily possible through the WiFiManager API if WiFi is on. Is there any way to get the MAC address if WiFi is off and WiFi Direct is on? WiFi AND WiFi Direct can't be on at same time on my phone. Thanks 回答1: I had been searching for this during my project. My requirements were to uniquely identify devices in an adhoc P2p network formed with WiFi Direct. Each device should identify its friend device the next time when it

问题 I am currently experimenting with WiFi-Direct (WiFiP2p) for a project I'm working on and wanted to know if one can create bridge between groups, thus joining them together? Based upon the white paper released by the WiFi Alliance, it should be possible (though "The P2P Specification does not describe the mechanism for this capability – implementation is specific to the vendor"). I have looked through the internet and have found some answers (this, this, etc.) but I feel that none are
