How to enable/disable WiFi from an application?

Question

I want to enable/disable wifi from my Android application. How can I do that?

Solution 1

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(false); // true or false to activate/deactivate wifi

You also need to request the permission in your AndroidManifest.xml :

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

Solution 2

To enable/disable WiFi in your application you need to use WiFiManager class. Create an Object of WiFiManager class to get the services of WiFi.

WifiManager wifi;
wifi=(WifiManager)getSystemService(Context.WIFI_SERVICE);

wifi.setWifiEnabled(false);//Turn off Wifi

wifi.setWifiEnabled(true);//Turn on Wifi

And you have to put the following permissions in AndroidManifest.xml

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

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

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

<uses-permission android:name="android.permission.WAKE_LOCK" />

Solution 3

try this code

 Intent gpsOptionsIntent = new Intent(  android.provider.Settings.ACTION_WIFI_SETTINGS);  
            startActivityForResult(gpsOptionsIntent,0); 

Solution 4

try this

public void disableWifi(Context context, Boolean bool) {
    WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

    if(bool)
        wifi.setWifiEnabled(false);
    else
        wifi.setWifiEnabled(true);
}

Solution 5

To enable/disable wifi from an app in Android Q (Android 10) use Settings Panel:

val panelIntent = Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY)
startActivityForResult(panelIntent, 0)

On previous versions of Android this should work (appropriate permissions should be added to AndroidManifest file, see answers above):

(context?.getSystemService(Context.WIFI_SERVICE) as? WifiManager)?.apply { isWifiEnabled = true /*or false*/ }

Resulting code might look something like this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    val panelIntent = Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY)
    startActivityForResult(panelIntent, 0)
} else {
    (context?.getSystemService(Context.WIFI_SERVICE) as? WifiManager)?.apply { isWifiEnabled = true /*or false*/ }
}

Where context is a reference to android.content.Context object.
