问题 I'm calling the function WifiManager.addNetwork(WifiConfiguration) to try and add an adhoc wifi network to the device's wifi configurations. But on Android M this function returns -1, I'm assuming because it doesn't have internet access. It works fine on most other devices. Below is code snippet I'm using. WifiConfiguration wifiConfiguration = new WifiConfiguration(); wifiConfiguration.SSID = '\"' + ssid + '\"'; wifiConfiguration.hiddenSSID = false; wifiConfiguration.allowedKeyManagement.set

问题 i can't connect Android on SSID established, i try WifiConfiguration but unsucessfull, my ssid is open (without password). In Android UI i can connect, but on code i can't. Anybody help me? Tankyou. EDIT: my code: String networkSSID = "DL63.0.0.0.1"; String networkPass = ""; WifiConfiguration conf = new WifiConfiguration(); conf.SSID = "\"" + networkSSID + "\""; // conf.wepKeys[0] = "\"" + networkPass + "\""; // conf.wepTxKeyIndex = 0; conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt

问题 Was going through Android documentation and had few doubts: Using "Wi-Fi direct" in Android 4.0+, is it possible to establish connection pragmatically with NON "Wi-Fi direct" enabled network device? For example, is it possible to communicate with older smartphone (having Android 2.2 OS) with the latest 4.1 based Android Smartphone. I want to use Wi-Fi direct capablities to perform FTP operation on various kinds of smartphones (android, iOS) Thanks. 回答1: I am using an APP named FileDrop which

问题 I got this code that i want to scan for the networks and then write it all to the listview. But the problem is that the ssid and bssid doesnt show. Everything else shows but not the ssid. Also what is the best way to update the listview every second so you can see the signal strenghts actual signal? import java.util.List; import android.annotation.SuppressLint; import android.app.Activity; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent;

问题 I'm trying to create a WifiConfiguration for Android. All other properties can be set. But if i try to set the SSID or BSSID, i'm getting a segmentation fault (11) and the app and Delphi just hangs. var WIFIConfig: JWifiConfiguration; begin WIFIConfig := TJWifiConfiguration.JavaClass.init; WIFIConfig.hiddenSSID := false; -> works WIFIConfig.SSID := StringtoJString('"YOUR_WLAN_SSID"'); -> App just hangs end; http://developer.android.com/reference/android/net/wifi/WifiConfiguration.html

问题 I am writing a program to always connect to the strongest access point. I mean the access point with the strongest signal. First I scan all the available WiFi networks and then I restrict them to see just the ones with the same SSID. So I can see all the APs of one network. When I connect to that network it doesn't connect to the strongest signal but I want it to switch to the strongest AP signal. By WifiManager.compareSignalLevel(bestSignal.level, connectedAP.level) <0 I understand the best

问题 I am having some strange issues when I want to verify, whether an Android device is connected to a specific Wi-Fi (identified by SSID) AND it has a MOBILE data network active at the same time. It is also likely that my issue is connected to Android 9 (SDK 28), as I did not get any complaints from users with previous Android versions. So here is what I have: This is my main method, that should tell me whether the device is currently connected to it's target Wi-Fi: public boolean

问题 I'm using the following code to detect and connect to specific WiFi ssid when I press a button in android. Below is the code. Any help will be appreciated. ssid :- "myHotspot" & password:- "12345678" Button b1 = (Button) findViewById(R.id.button); <br> b1.setOnClickListener(new View.OnClickListener() { <br><br>@Override <br>public void onClick(View v) { wifiConfiguration.SSID = "\"myHotspot\""; wifiConfiguration.preSharedKey ="\"12345678\""; WifiManager wifiManager = (WifiManager)

问题 I want to show alert that connection not available in my android application. I am calling some rest request in my application. To check this network unavailability scenario I manually disconnect my wifi in my laptop (I am testing in simulator) . Code where I call service is here resp = client.execute(httpPostRequest); and here I am catching exception catch (IllegalStateException e) { //assertTrue(e.getLocalizedMessage(), false); e.printStackTrace(); } catch (ClientProtocolException e) { /

问题 After reading some answers and trying to use them I still can not make my code return a correct state, if there is internet over wifi or not. I must "ping" over WIFI, because we may be connected to the Access Point with no further internet connection. Here is a complete code. ConnectivityManager CM = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo NI = CM.getActiveNetworkInfo(); boolean IC = false; IC = CM.requestRouteToHost(ConnectivityManager.TYPE
