Android Question Inline Java code

[Rusty]

I'm trying to sign into a (known) hidden SSID with this java code:

...
Sub Process_Globals
...
Private NativeMe As JavaObject
...
            Dim Credentials(2) As String
            Credentials(0) = SSID
            Credentials(1) = Pass
            NativeMe.InitializeContext
            NativeMe.RunMethod("setWifiConfig", Credentials)    'run the Java method
...

#If JAVA
public void setwificonfig(string ssid, string sharedkey) {
            wificonfiguration conf = new wificonfiguration();
    conf.ssid = "\"" + ssid + "\"";   // please note the quotes. string should contain ssid in quotes

    conf.presharedkey = "\"" + sharedkey + "\"";

    conf.hiddenssid = true;
    conf.status = wificonfiguration.status.enabled;
    conf.allowedgroupciphers.set(wificonfiguration.groupcipher.tkip);
    conf.allowedgroupciphers.set(wificonfiguration.groupcipher.ccmp);
    conf.allowedkeymanagement.set(wificonfiguration.keymgmt.wpa_psk);
    conf.allowedpairwiseciphers.set(wificonfiguration.pairwisecipher.tkip);
    conf.allowedpairwiseciphers.set(wificonfiguration.pairwisecipher.ccmp);
    conf.allowedprotocols.set(wificonfiguration.protocol.rsn);
    conf.allowedprotocols.set(wificonfiguration.protocol.wpa);

    wifimanager wifimanager = (wifimanager)context.getsystemservice(context.wifi_service);

    wifimanager.addnetwork(conf);

    list<wificonfiguration> list = wifimanager.getconfigurednetworks();
    for (wificonfiguration i : list) {
        if (i.ssid != null && i.ssid.equals("\"" + ssid + "\"")) {

            wifimanager.disconnect();

            wifimanager.enablenetwork(i.networkid, true);

            wifimanager.reconnect();

            wifimanager.saveconfiguration();
            break;
        }
    }
}
#End If

found here on stack overflow.
When I compile it, I am getting this error:

src\talkingsurvey\b4a\surveydeploy\main.java:2329: error: cannot find symbol
public void setwificonfig(string ssid, string sharedkey) {
^

Can someone assist me with this? I'm not sure what is wrong with it...
Thanks in advance,
Rusty

Dim Credentials(2) As String
Credentials(0) = SSID
Credentials(1) = Pass
NativeMe.InitializeContext
NativeMe.RunMethod("setWifiConfig", Credentials)

is not the same as

 setwificonfig(string ssid, string sharedkey)

The later one expects TWO Strings. But you are giving one Array.

Rewrite the java method to expect a array and split it in the java method into two strings....

 

[Rusty]

Is there a way to pass it two parameters?
I tried

Setwificonfig(SSID, PSWD)

and it didn't like that either...?
Thanks for the help, Don...

 

[DonManfred]

and it didn't like that either...?

It must work....

    Dim Credentials(2) As String
    Credentials(0) = "SSSS"
    Credentials(1) = "PPPP"

    nativeMe.RunMethod("methodName", Credentials)

public void methodName(String s1,String s2){
    BA.Log(s1 + " " + s2);
}

SSSS PPPP

 

[DonManfred]

There are SOME wrong propertynames in your code. After 4 or 5 fixed i gave up.
Find the rest by yourself....

    Dim Credentials(2) As String
    Credentials(0) = $""SSSS""$ ' Add the quote in B4A....
    Credentials(1) = "PPPP"

Note that Objects and propertynames in Java are casesensitive... Starting with WifiConfiguration instead of wificonfiguration!
Paramtype in Java is String, not string.
and so on....

import android.net.wifi.WifiConfiguration;
public void setwificonfig(String ssid, String sharedkey) {
    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = ssid;   // please note the quotes. string should contain ssid in quotes
    conf.preSharedKey = "\"" + sharedkey + "\"";

    conf.hiddenSSID = true;
    conf.status = WifiConfiguration.status.enabled;
 
        conf.allowedgroupciphers.set(WifiConfiguration.groupcipher.tkip);
    conf.allowedgroupciphers.set(WifiConfiguration.groupcipher.ccmp);
    conf.allowedkeymanagement.set(WifiConfiguration.keymgmt.wpa_psk);
    conf.allowedpairwiseciphers.set(WifiConfiguration.pairwisecipher.tkip);
    conf.allowedpairwiseciphers.set(WifiConfiguration.pairwisecipher.ccmp);
    conf.allowedprotocols.set(WifiConfiguration.protocol.rsn);
    conf.allowedprotocols.set(WifiConfiguration.protocol.wpa);

    wifimanager wifimanager = (wifimanager)context.getsystemservice(context.wifi_service);

    wifimanager.addnetwork(conf);

    list<wificonfiguration> list = wifimanager.getconfigurednetworks();
    for (wificonfiguration i : list) {
        if (i.ssid != null && i.ssid.equals("\"" + ssid + "\"")) {

            wifimanager.disconnect();

            wifimanager.enablenetwork(i.networkid, true);

            wifimanager.reconnect();

            wifimanager.saveconfiguration();
            break;
        }
    }
}

symbol: class string

You could try this code:

Sub ConnectToWifi
    Dim ssid, pass As String
    Dim jo As JavaObject
    ssid = "your ssid"
    pass = "your password"
    jo.InitializeContext
    jo.RunMethod("setwificonfig", Array(ssid, pass))
End Sub

#If JAVA
import java.util.List;
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;
import android.content.Context;
import android.util.Log;

     public void setwificonfig(String ssid, String sharedkey) {
        WifiConfiguration conf = new WifiConfiguration();
        conf.SSID = ssid;   // please note the quotes. string should contain ssid in quotes
        conf.preSharedKey = "\"" + sharedkey + "\"";

        conf.hiddenSSID = true;
        conf.status = WifiConfiguration.Status.ENABLED;
    
            conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
        conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
        conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        Context context = this.getApplicationContext();
        WifiManager wifimanager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);

        wifimanager.addNetwork(conf);

        List<WifiConfiguration> list = wifimanager.getConfiguredNetworks();
//        Log.w("B4A", "size "+list.size());
//        Log.w("B4A", list.toString());
        for (WifiConfiguration i : list) {
            if (i.SSID != null && i.SSID.equals("\"" + ssid + "\"")) {

                wifimanager.disconnect();

                wifimanager.enableNetwork(i.networkId, true);

                wifimanager.reconnect();

                wifimanager.saveConfiguration();
                break;
            }
        }
    }
#End If

Compare your code with mine and you will understand what Don said about "case sensitivity"
My advise for future:
1. If you copy java code, make sure you do it exactly as the source is. As Don said, it is case sensitive
2. Copy you java code into Eclipse java project and you will get hints about imports that have to be added and any other errors.

I hope that it helps
