Enable/disable data and WiFi connection in android programmatically

For accessing the WIFI state :

WifiManager wifiManager ;
wifiManager  = (WifiManager)this.getSystemService(this.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);        //True - to enable WIFI connectivity .



For accessing the DATA/3G state :


ConnectivityManager dataManager;
dataManager  = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
Method dataMtd = ConnectivityManager.class.getDeclaredMethod("setMobileDataEnabled", boolean.class);
dataMtd.setAccessible(true);
dataMtd.invoke(dataManager, true);        //True - to enable data connectivity .

Now you need to add this permissions in Manifest file :


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