Android turn On/Off WiFi HotSpot programmatically

Question

Is there an API to turn On/Off the WiFi HotSpot on Android programmatically?

What methods should I call to turn it On/Off?

UPDATE:There's this option to have the HotSpot enabled, and just turn On/Off the WiFi, but this is not a good solution for me.

Warning This method will not work beyond 5.0, it was a quite dated entry.

Use the class below to change/check the Wifi hotspot setting:

import android.content.*; import android.net.wifi.*; import java.lang.reflect.*;  public class ApManager {  //check whether wifi hotspot on or off public static boolean isApOn(Context context) {     WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);          try {         Method method = wifimanager.getClass().getDeclaredMethod("isWifiApEnabled");         method.setAccessible(true);         return (Boolean) method.invoke(wifimanager);     }     catch (Throwable ignored) {}     return false; }  // toggle wifi hotspot on or off public static boolean configApState(Context context) {     WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);     WifiConfiguration wificonfiguration = null;     try {           // if WiFi is on, turn it off         if(isApOn(context)) {                            wifimanager.setWifiEnabled(false);         }                        Method method = wifimanager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);                            method.invoke(wifimanager, wificonfiguration, !isApOn(context));         return true;     }      catch (Exception e) {         e.printStackTrace();     }            return false; } } // end of class 

You need to add the permissions below to your AndroidMainfest:

<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 

Use this standalone ApManager class from anywhere as follows:

ApManager.isApOn(YourActivity.this); // check Ap state :boolean ApManager.configApState(YourActivity.this); // change Ap state :boolean 

Hope this will help someone
