In Android 1.5 (also on 1.6)
How to add an Access Point from code?
Given Access point that supports WPA2. Here is my code snippet.
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
// This is must be quoted according to the documentation
// http://developer.android.com/reference/android/net/wifi/WifiConfiguration.html#SSID
wc.SSID = "\"SSIDName\"";
wc.preSharedKey = "password";
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean b = wifi.enableNetwork(res, true);
Log.d("WifiPreference", "enableNetwork returned " + b );
This code fails as in LogCat appear
01-26 16:44:13.550: ERROR/wpa_supplicant(2032): Line 0: Invalid PSK 'password'.
I am sure that this is the password and that all of the rest of the parameters are right. What do I do I miss?
The reason for the my sorrow is here in this Documentation issue
While documentation here states
"Pre-shared key for use with WPA-PSK. When the value of this key is read, the actual key is not returned, just a "*" if the key has a value, or the null string otherwise."
It is correct, but very important what it does not say is that expected here ether 64 byte hash result of the linux command
wpa_passphrase <ssid> [passphrase]
or Access Point's password IN DOUBLE QUOTES!
So in case that Access Point's PSK is "example" it has to be passed in java like this
WifiConfiguration myWiFiConfig = new WifiConfiguration();
...
myWiFiConfig.preSharedKey = "\"example\"";
...
OR
myWiFiConfig.preSharedKey = "0a0b0f62170ecc5bcf721b6ff170b8b560101b5d56b00a26abec217e0bb4aa1f";
For all the rest of you that will stumble on this the right way is:
Copy&Paste it as is and save your self half a day of pain we already spent on it (Special Thanks to Reflog)
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = "\"SSIDName\"";
wc.preSharedKey = "\"password\"";
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = wifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean b = wifi.enableNetwork(res, true);
Log.d("WifiPreference", "enableNetwork returned " + b );
