Create Wifi Hotspot Configuration in android

Question

I am using android 4.1.1 ... I am making an application that allows the user to make his own network using Wifi Hotspot and then the clients can connect to it and share data. I have successfully created the Wifi hotspot in android but I cannot configure it for the purpose. Is there any way to configure Wifi Hotspot on android through coding ??

This answer maybe outdated!

if(wifiManager.isWifiEnabled())
{
    wifiManager.setWifiEnabled(false); 
}

WifiConfiguration netConfig = new WifiConfiguration();

netConfig.SSID = "MyAP";
netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

try{
    Method setWifiApMethod = wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
    boolean apstatus=(Boolean) setWifiApMethod.invoke(wifiManager, netConfig,true);

    Method isWifiApEnabledmethod = wifiManager.getClass().getMethod("isWifiApEnabled"); 
    while(!(Boolean)isWifiApEnabledmethod.invoke(wifiManager)){};
    Method getWifiApStateMethod = wifiManager.getClass().getMethod("getWifiApState"); 
    int apstate=(Integer)getWifiApStateMethod.invoke(wifiManager);
    Method getWifiApConfigurationMethod = wifiManager.getClass().getMethod("getWifiApConfiguration");
    netConfig=(WifiConfiguration)getWifiApConfigurationMethod.invoke(wifiManager);
    Log.e("CLIENT", "\nSSID:"+netConfig.SSID+"\nPassword:"+netConfig.preSharedKey+"\n");

} catch (Exception e) {
    Log.e(this.getClass().toString(), "", e);
}

Is there any setWifiApConfiguration for this Wifi HotSpot so I can connect to custom wifi access point using code. – Afflux

Doesn't work on Android 6 and 5.1 above. I have added the ACTION_MANAGE_WRITE_SETTINGS permission but still getting error as Exception in softap start java.lang.IllegalStateException: command '2707 softap set wlan0 .... – Ciccia

@AkshayTaru No surprise! at the time I answered the latest version of android was 5.0 , I hope you can update the answer. – Further

Here is a possible solution:

private WifiManager.LocalOnlyHotspotReservation mReservation;

 WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);

wifiManager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {

        @Override
        public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
            super.onStarted(reservation);
            mReservation = reservation;
        }

        @Override
        public void onStopped() {
            super.onStopped();
        }

        @Override
        public void onFailed(int reason) {
            super.onFailed(reason);
        }
    }, new Handler());
