Android programmatically enable wifi

Is it possible to programmatically enable wifi on Android 10 devices?

Since setWifiEnabled is deprecated on Android 10, how does one programatically enable wifi on Android 10 devices? Is it not possible to programmatically enable wifi at all on Android 10+ (SDK 29) ?

No, This is not possible to enable or disable Wi-Fi programmatically from Android-10 API level 29 [Until google provides an alternative solution].

For applications targeting Build.VERSION_CODES.Q or above, this API will always return false and will have no effect.

If apps are targeting an older SDK ( Build.VERSION_CODES.P or below), they can continue to use this API.

There is an issue 128554616 which already has been created in google issuetracker forum. You can see there for any updated info.

I have updated my answer with an issuetracker which is already created in google forum. hope you can find more info from thers. Happy Coding.

I am using the val wifiManager = context.getSystemService(Context.WIFI_SERVICE) as WifiManager wifiManager.isWifiEnabled = true FOR ENABLING THE WIFI in android 8 BUT its not working. Any other option

Now in android 10 you can do like this

Intent panelIntent = new Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY); startActivityForResult(panelIntent); 

ACTION_INTERNET_CONNECTIVITY Shows settings related to internet connectivity, such as Airplane mode, Wi-Fi, and Mobile Data.

ACTION_WIFI Shows Wi-Fi settings, but not the other connectivity settings. This is useful for apps that need a Wi-Fi connection to perform large uploads or downloads.

ACTION_NFC Shows all settings related to near-field communication (NFC).

ACTION_VOLUME Shows volume settings for all audio streams.

How to enable/disable wifi or internet connection programmatically in Android?

In the world of mobile app development, it is often necessary to control the device’s internet and Wi-Fi connectivity programmatically. For example, you may want to disable the Wi-Fi or internet connection in certain circumstances, such as when the device is running low on battery or the user has requested to turn off the connection. On Android, this can be achieved through the use of the ConnectivityManager class, which provides access to the device’s network information and helps to manage its connectivity state.

Method 1: Disable Wi-Fi

To disable Wi-Fi programmatically in Android, you can use the following steps:

1. Get an instance of the WifiManager class using the getSystemService method and pass in the Context.WIFI_SERVICE parameter.

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

wifiManager.setWifiEnabled(false);

Here’s the complete code example:

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE); wifiManager.setWifiEnabled(false);

This code will disable Wi-Fi programmatically in Android.

Method 2: Disable Mobile Data

To disable mobile data programmatically in Android, you can use the ConnectivityManager class. Here are the steps to do it:

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

boolean isMobileDataEnabled = connManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnected();

if (isMobileDataEnabled)  connManager.setNetworkPreference(ConnectivityManager.TYPE_WIFI); connManager.setNetworkPreference(ConnectivityManager.TYPE_MOBILE); connManager.setMobileDataEnabled(false); >

Here, we first set the network preference to Wi-Fi and then to mobile data. This is to ensure that mobile data is disabled even if the device is currently using it for internet connectivity.

That’s it! With these simple steps, you can programmatically disable mobile data in your Android app.

Method 3: Enable Wi-Fi

To enable Wi-Fi programmatically in Android, you can use the WifiManager class. Here are the steps to do it:

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);

if (!wifiManager.isWifiEnabled())  // Wi-Fi is disabled, enable it wifiManager.setWifiEnabled(true); >

if (wifiManager.isWifiEnabled())  // Wi-Fi is enabled, disable it wifiManager.setWifiEnabled(false); >

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE); if (!wifiManager.isWifiEnabled())  wifiManager.setWifiEnabled(true); > // To disable Wi-Fi // if (wifiManager.isWifiEnabled()) // wifiManager.setWifiEnabled(false); // >

That’s it! You can now enable Wi-Fi programmatically in your Android app.

Method 4: Enable Mobile Data

To enable or disable internet connectivity programmatically in Android, you can use the ConnectivityManager class. Here is an example of how to enable mobile data:

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

ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

// To enable mobile data try  final Class?> conmanClass = Class.forName(cm.getClass().getName()); final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService"); iConnectivityManagerField.setAccessible(true); final Object iConnectivityManager = iConnectivityManagerField.get(cm); final Class?> iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName()); final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE); setMobileDataEnabledMethod.setAccessible(true); setMobileDataEnabledMethod.invoke(iConnectivityManager, true); > catch (Exception e)  e.printStackTrace(); > // To disable mobile data try  final Class?> conmanClass = Class.forName(cm.getClass().getName()); final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService"); iConnectivityManagerField.setAccessible(true); final Object iConnectivityManager = iConnectivityManagerField.get(cm); final Class?> iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName()); final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE); setMobileDataEnabledMethod.setAccessible(true); setMobileDataEnabledMethod.invoke(iConnectivityManager, false); > catch (Exception e)  e.printStackTrace(); >

Note: This method requires the app to have the CHANGE_NETWORK_STATE permission and may not work on all Android versions or devices.

How to enable/disable WiFi from an application?

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

@Codii, I know this is old, but I am trying to do this within a dialogfragment. However, it says «Cannot resolve method ‘getSystemService(java.lang.String)’ I am not sure on what I need to do. And I have those permissions

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

To get the whole sample code of enable/disable Wifi in android with UI visit this website

when i do it in my project, but when these code is executed, the system will give a prompt says the app is trying to use wlan whether allows it. and it appears every time! can i enable wlan without the prompt window .

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

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.
