Programmatically connect to an android device in Portable hotspot

Question

I have succesfully created a portable hotspot programmatically on my device with a specified SSID. Now I want to connect to it from another device! I'm using this code:

    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = "\"" + "TinyBox" + "\"";
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    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("\"" + "TinyBox" + "\"")) {
             wifiManager.disconnect();
             wifiManager.enableNetwork(i.networkId, true);
             wifiManager.reconnect();               
             break;
        }           
    }

But nothing happens. Where is the mistake? Thanks

So guys I found the problem! The SSID was wrong because of the quotes "". So if you create an open portable hotspot with the following code (I took it somewhere on the net):

    WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    if(wifiManager.isWifiEnabled())
    {
        wifiManager.setWifiEnabled(false);          
    }       
    Method[] wmMethods = wifiManager.getClass().getDeclaredMethods();   //Get all declared methods in WifiManager class     
    boolean methodFound=false;
    for(Method method: wmMethods){
        if(method.getName().equals("setWifiApEnabled")){
            methodFound=true;
            WifiConfiguration netConfig = new WifiConfiguration();
            netConfig.SSID = "\""+"TinyBox"+"\"";
            netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);

            try {
                boolean apstatus=(Boolean) method.invoke(wifiManager, netConfig,true);          
                for (Method isWifiApEnabledmethod: wmMethods)
                {
                    if(isWifiApEnabledmethod.getName().equals("isWifiApEnabled")){
                        while(!(Boolean)isWifiApEnabledmethod.invoke(wifiManager)){
                        };
                        for(Method method1: wmMethods){
                            if(method1.getName().equals("getWifiApState")){
                                int apstate;
                                apstate=(Integer)method1.invoke(wifiManager);
                            }
                        }
                    }
                }
                if(apstatus)
                {
                    System.out.println("SUCCESSdddd");  

                }else
                {
                    System.out.println("FAILED");   

                }

            } catch (IllegalArgumentException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }
        }      
    }

You need to connect to it using:

    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = "\"\"" + "TinyBox" + "\"\"";
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    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("\"\"" + "TinyBox" + "\"\"")) {
            try {
                wifiManager.disconnect();
                wifiManager.enableNetwork(i.networkId, true);
                System.out.print("i.networkId " + i.networkId + "\n");
                wifiManager.reconnect();               
                break;
            }
            catch (Exception e) {
                e.printStackTrace();
            }

        }           
    }
