How to set secured hotspot in android (with password)

I want to set the hotspot on with it's ssid and password configured because i want to share it with some devices. The code i am using below works fine for me but i am unable to set the password of hotspot.

if (wm.isWifiEnabled()) {
                    wm.setWifiEnabled(false);
                }
                WifiConfiguration wifiCon = new WifiConfiguration();
                wifiCon.SSID = "UsmanAp";
                wifiCon.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
                wifiCon.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
                wifiCon.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
                wifiCon.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                try{
                    Method setWifiApMethod = wm.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
                    boolean apstatus=(Boolean) setWifiApMethod.invoke(wm, wifiCon,true);
                    Method isWifiApEnabledmethod = wm.getClass().getMethod("isWifiApEnabled"); 
                    while(!(Boolean)isWifiApEnabledmethod.invoke(wm)){};
                    Method getWifiApStateMethod = wm.getClass().getMethod("getWifiApState"); 
                    int apstate=(Integer)getWifiApStateMethod.invoke(wm);
                    Method getWifiApConfigurationMethod = wm.getClass().getMethod("getWifiApConfiguration");
                    wifiCon=(WifiConfiguration)getWifiApConfigurationMethod.invoke(wm);
                } catch (Exception e) {
                    Log.e(this.getClass().toString(), "", e);
                }

What do add in the above code to set the password of the hotspot.

You are not setting the preSharedKey, which is the password for WPA. Also the allowedKeyManagement should be set to WifiConfiguration.KeyMgmt.WPA_PSK.

WifiConfiguration wifiCon = new WifiConfiguration();
wifiCon.SSID = "UsmanAp";
wifiCon.preSharedKey = "password";
wifiCon.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
wifiCon.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wifiCon.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wifiCon.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
try
{
    Method setWifiApMethod = wm.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
    boolean apstatus=(Boolean) setWifiApMethod.invoke(wm, wifiCon,true);
} 
catch (Exception e) 
{
    Log.e(this.getClass().toString(), "", e);
}
