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 reading existing Wi Fi configuration. Code is pretty decent WifiManager wifiMgr = (WifiManager) getSystemService(Context.WIFI_SERVICE); List<WifiConfiguration> configurations= null; if (wifiMgr != null) { configurations = wifiMgr.getConfiguredNetworks(); } I have necessary permissions: <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission> The problem is- all (at least

问题 As a newbie to Android programming, I am trying to get the SSID list using WifiManager's getScanResults() method, but it remains empty, even though I have granted it the ACCESS_COARSE_LOCATION permission as well as the CHANGE_WIFI_STATE (for the startScan() method), both in the manifest and by checking/requesting it at runtime. In the broadcast receiver for the SCAN_RESULTS_AVAILABLE_ACTION , I even check the extra field of the intent with key EXTRA_RESULTS_UPDATED and the result returns true

问题 Good day all In short, WifiManager.java is a source module given by Google API's for Wifi related functions. its class declaration : public class WifiManager { obviously contains many functions, of which some I am able to access, and no they are not private functions from the class description: This class provides the primary API for managing all aspects of Wi-Fi connectivity. Get an instance of this class by calling {@link android.content.Context#getSystemService(String) Context
