How to Enable/Disable WiFi problematically in Android ?

Using “setWifiEnabled” API in Android, you can enable or disable Wi-Fi programmatically. Below an example of how to do this in an Android app:

import android.content.Context;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import androidx.appcompat.app.AppCompatActivity;

public class WifiControlActivity extends AppCompatActivity {

    private Button enableWifiButton;
    private Button disableWifiButton;
    private WifiManager wifiManager;

    protected void onCreate(Bundle savedInstanceState) {

        // Initialize the WifiManager
        wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);

        enableWifiButton = findViewById(R.id.enableWifiButton);
        disableWifiButton = findViewById(R.id.disableWifiButton);

        enableWifiButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

        disableWifiButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

    private void enableWifi() {
        if (!wifiManager.isWifiEnabled()) {

    private void disableWifi() {
        if (wifiManager.isWifiEnabled()) {

n this example:

  1. We have an WifiControlActivity that contains two buttons (enableWifiButton and disableWifiButton) and a WifiManager object.
  2. In the onCreate method, we initialize the WifiManager using getSystemService(Context.WIFI_SERVICE).
  3. We set OnClickListener for both buttons to enable and disable Wi-Fi when they are clicked.
  4. The enableWifi method checks if Wi-Fi is not already enabled and then uses setWifiEnabled(true) to enable it.
  5. The disableWifi method checks if Wi-Fi is enabled and then uses setWifiEnabled(false) to disable it.

Make sure you have the appropriate permissions declared in your AndroidManifest.xml file to control Wi-Fi:

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

Also, you’ll need to create the corresponding XML layout (activity_wifi_control.xml) to define the UI with the two buttons.

Limitation :

The API “setWiFiEnabled” has been deprecated for using for normal application after API level 29 or Android 10. Hence we can’t turn ON / OFF the wifi using the example mentioned above.

Solution :

The only solution to use the “setWiFiEnabled” API to turn ON / OFF the WiFi after Android 10 is to make sure our application as system UID and the application has been signed with the platform key.
