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 am trying to connect to WiFi using the WifiNetworkSpecifier on Android Q. The problem which I run into is Android always using the last valid credentials to connect to the AP, even after I manually provide the new, updated credentials to the WifiNetworkSpecifier. This is the flow: Successfully connect to the AP. Change the password of the WiFi network. Run the app, try to connect again with the updated credentials (new, valid password provided) but the app can't connect to the WiFi

问题 I'm writing a client application for my action camera. There's an issue using network connections when smartphone connected to wifi and mobile network: Android determines, that wifi does not connected to internet, so all requests passed to mobile network interface. I've already implemented the client API, that uses pre-bounded sockets to communicate with camera: public class MainActivity extends AppCompatActivity { private Network wifi; @Override protected void onCreate(Bundle

问题 Is it possible to retrieve the MAC addresses of all available WiFi networks? I know you can do it for the network you're currently connected to: WifiManager wifiMan = (WifiManager) this.getSystemService( Context.WIFI_SERVICE); WifiInfo wifiInf = wifiMan.getConnectionInfo(); String macAddr = wifiInf.getMacAddress(); But is it also possible for networks you're not connected to? Edit: Is it at all possible under the OSI model (http://en.wikipedia.org/wiki/OSI_model) ? It seems like the MAC
