У вас есть идея установить Wi-Fi-соединение с отправкой пароля в приложении для Android?
Android WiFi соединение программно
Ответ 1
Передайте SSID и его пароль следующему методу.
public void connectToAP(String ssid, String passkey) {
Log.i(TAG, "* connectToAP");
WifiConfiguration wifiConfiguration = new WifiConfiguration();
String networkSSID = ssid;
String networkPass = passkey;
Log.d(TAG, "# password " + networkPass);
for (ScanResult result : scanResultList) {
if (result.SSID.equals(networkSSID)) {
String securityMode = getScanResultSecurity(result);
if (securityMode.equalsIgnoreCase("OPEN")) {
wifiConfiguration.SSID = "\"" + networkSSID + "\"";
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
int res = wifiManager.addNetwork(wifiConfiguration);
Log.d(TAG, "# add Network returned " + res);
boolean b = wifiManager.enableNetwork(res, true);
Log.d(TAG, "# enableNetwork returned " + b);
wifiManager.setWifiEnabled(true);
} else if (securityMode.equalsIgnoreCase("WEP")) {
wifiConfiguration.SSID = "\"" + networkSSID + "\"";
wifiConfiguration.wepKeys[0] = "\"" + networkPass + "\"";
wifiConfiguration.wepTxKeyIndex = 0;
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
int res = wifiManager.addNetwork(wifiConfiguration);
Log.d(TAG, "### 1 ### add Network returned " + res);
boolean b = wifiManager.enableNetwork(res, true);
Log.d(TAG, "# enableNetwork returned " + b);
wifiManager.setWifiEnabled(true);
}
wifiConfiguration.SSID = "\"" + networkSSID + "\"";
wifiConfiguration.preSharedKey = "\"" + networkPass + "\"";
wifiConfiguration.hiddenSSID = true;
wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
int res = wifiManager.addNetwork(wifiConfiguration);
Log.d(TAG, "### 2 ### add Network returned " + res);
wifiManager.enableNetwork(res, true);
boolean changeHappen = wifiManager.saveConfiguration();
if(res != -1 && changeHappen){
Log.d(TAG, "### Change happen");
AppStaticVar.connectedSsidName = networkSSID;
}else{
Log.d(TAG, "*** Change NOT happen");
}
wifiManager.setWifiEnabled(true);
}
}
}
public String getScanResultSecurity(ScanResult scanResult) {
Log.i(TAG, "* getScanResultSecurity");
final String cap = scanResult.capabilities;
final String[] securityModes = { "WEP", "PSK", "EAP" };
for (int i = securityModes.length - 1; i >= 0; i--) {
if (cap.contains(securityModes[i])) {
return securityModes[i];
}
}
return "OPEN";
}
Не забудьте добавить необходимые разрешения в файл манифеста.

100% работает.
Таким образом, вы можете подключиться к вашему конкретному Wi-Fi Этот код для MainActivity.java
//////////////>>> Wifi Connection (WP2) <<<////////////////////
WifiConfiguration wifiConfig = new WifiConfiguration();
wifiConfig.SSID = String.format("\"%s\"", "Wifi name");
wifiConfig.preSharedKey = String.format("\"%s\"", "Wifi password");
WifiManager wifiManager=(WifiManager)getSystemService(WIFI_SERVICE);
int netId = wifiManager.addNetwork(wifiConfig);
wifiManager.disconnect();
wifiManager.enableNetwork(netId, true);
wifiManager.reconnect();
И также не забудьте включить этот код в ваш AndroidManifest.xml
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

Код, отправленный из AnujAroshA, здесь действительно полезен. Но нет другого случая:
..
} else if (securityMode.equalsIgnoreCase("PSK")) {
// PSK code
..
В противном случае код PSK также выполняется для сетей WEP и OPEN.
И стиль кода на мой взгляд не оптимален. Нет необходимости создавать две строки networkSSID и networkPass. Вы можете просто использовать ssid или passkey.
Предложение: Разделить создание wifi-конфигурации и метода подключения.
(1) Способ создания WifiConfiguration:
private WifiConfiguration createAPConfiguration(String networkSSID, String networkPasskey, String securityMode) {
WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.SSID = "\"" + networkSSID + "\"";
if (securityMode.equalsIgnoreCase("OPEN")) {
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
} else if (securityMode.equalsIgnoreCase("WEP")) {
wifiConfiguration.wepKeys[0] = "\"" + networkPasskey + "\"";
wifiConfiguration.wepTxKeyIndex = 0;
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
} else if (securityMode.equalsIgnoreCase("PSK")) {
wifiConfiguration.preSharedKey = "\"" + networkPasskey + "\"";
wifiConfiguration.hiddenSSID = true;
wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
} else {
Log.i(TAG, "# Unsupported security mode: "+securityMode);
return null;
}
return wifiConfiguration;
}
(2) Способ подключения AP:
public int connectToAP(String networkSSID, String networkPasskey) {
for (ScanResult result : scanResultList) {
if (result.SSID.equals(networkSSID)) {
String securityMode = getScanResultSecurity(result);
WifiConfiguration wifiConfiguration = createAPConfiguration(networkSSID, networkPasskey, securityMode);
int res = wifiManager.addNetwork(wifiConfiguration);
Log.d(TAG, "# addNetwork returned " + res);
boolean b = wifiManager.enableNetwork(res, true);
Log.d(TAG, "# enableNetwork returned " + b);
wifiManager.setWifiEnabled(true);
boolean changeHappen = wifiManager.saveConfiguration();
if (res != -1 && changeHappen) {
Log.d(TAG, "# Change happen");
connectedSsidName = networkSSID;
} else {
Log.d(TAG, "# Change NOT happen");
}
return res;
}
}
return -1;
}
(3) Метод сканирования 100% отправлен AnujAroshA.
public String getScanResultSecurity(ScanResult scanResult) {
final String cap = scanResult.capabilities;
final String[] securityModes = { "WEP", "PSK", "EAP" };
for (int i = securityModes.length - 1; i >= 0; i--) {
if (cap.contains(securityModes[i])) {
return securityModes[i];
}
}
return "OPEN";
}

Дайте свой ssid и пароль
fun connectToWifi(ssid: String, password: String) {
val connManager = context!!.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
val networkInfo = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI)
val wifiConfiguration = WifiConfiguration()
wifiConfiguration.SSID = String.format("\"%s\"", ssid)
wifiConfiguration.preSharedKey = String.format("\"%s\"", password)
wifiManager = context!!.getSystemService(Context.WIFI_SERVICE) as WifiManager
val netId: Int = wifiManager.addNetwork(wifiConfiguration)
wifiManager.disconnect()
wifiManager.enableNetwork(netId, true)
wifiManager.reconnect()
val config = WifiConfiguration()
config.SSID == "\"\"" + ssid + "\"\""
config.preSharedKey == "\"\"" + password + "\"\""
wifiManager.addNetwork(config)
}
