For Android versions 10 and newer: WiFiUtils is currently using the Network request API (IoT API) for connecting to wifi networks which scopes the internet connectivity only to the app that requested it. There are plans to support WiFI Suggestion API in the future which overcomes this issue. For further info read the official docs here and take a look at the discussion thread here
WiFiUtils is a library that provides a set of convenience methods for managing WiFi State, WiFi Scan, And
WiFi Connection to Hotspots. If you have ever worked with WifiManager you should know how painful it is to make a simple wifi network scan or even worse
to connect to a hotspot programmatically. So that's what this library is all about. To make it easier for me and hopefully for other developers as well
to do those kind of tasks programmatically via a friendlier API.
Add the following to your app module build.gradle file
dependencies {
implementation("io.github.thanosfisherman.wifiutils:wifiutils:1.6.6")
}- My app of course GWPA Finder Duh :P
- react-native-wifi-reborn

turn on device's wifi using the following:
WifiUtils.withContext(getApplicationContext()).enableWifi(this::checkResult);Where checkResult could be a custom-defined method of your own that would deal accordingly in each situation. For Example:
private void checkResult(boolean isSuccess)
{
if (isSuccess)
Toast.makeText(MainActivity.this, "WIFI ENABLED", Toast.LENGTH_SHORT).show();
else
Toast.makeText(MainActivity.this, "COULDN'T ENABLE WIFI", Toast.LENGTH_SHORT).show();
}If you don't want to deal with call backs you can also call enableWifi method like so.
WifiUtils.withContext(getApplicationContext()).enableWifi();Similarly you can turn off the wifi using this:
WifiUtils.withContext(getApplicationContext()).disableWifi();You can easily perform a WiFi Network scan like so:
WifiUtils.withContext(getApplicationContext()).scanWifi(this::getScanResults).start();
private void getScanResults(@NonNull final List<ScanResult> results)
{
if (results.isEmpty())
{
Log.i(TAG, "SCAN RESULTS IT'S EMPTY");
return;
}
Log.i(TAG, "GOT SCAN RESULTS " + results);
}Now lets get to the interesting stuff. You can connect to any WiFi network programmatically knowing only SSID and WPA/WPA2 key:
WifiUtils.withContext(getApplicationContext())
.connectWith("JohnDoeWiFi", "JohnDoePassword")
.setTimeout(40000)
.onConnectionResult(new ConnectionSuccessListener() {
@Override
public void success() {
Toast.makeText(MainActivity.this, "SUCCESS!", Toast.LENGTH_SHORT).show();
}
@Override
public void failed(@NonNull ConnectionErrorCode errorCode) {
Toast.makeText(MainActivity.this, "EPIC FAIL!" + errorCode.toString(), Toast.LENGTH_SHORT).show();
}
})
.start();There are also a few other options that would allow you to do the same job but first
let's move the ConnectionSuccessListener from above into its own separate field named successListener so that we can save some space
private ConnectionSuccessListener successListener = new ConnectionSuccessListener() {
@Override
public void success() {
Toast.makeText(MainActivity.this, "SUCCESS!", Toast.LENGTH_SHORT).show();
}
@Override
public void failed(@NonNull ConnectionErrorCode errorCode) {
Toast.makeText(MainActivity.this, "EPIC FAIL!" + errorCode.toString(), Toast.LENGTH_SHORT).show();
}
};Connecting with SSID, BSSID and WPA/WPA2 key:
WifiUtils.withContext(getApplicationContext())
.connectWith("MitsarasWiFi", "AB:CD:EF:12:34:56", "MitsarasPassword123")
.onConnectionResult(successListener)
.start();Lastly WifiUtils can also connect using a specified scanResult after a WiFi Scan is complete, for example:
WifiUtils.withContext(getApplicationContext())
.connectWithScanResult("MitsarasPasword123", scanResults -> scanResults.get(0))
.onConnectionResult(successListener)
.start();The above example will perform a WiFi Scan and connectWithScanResult will return a List<ScanResult> scanResults with all the available WiFi networks
around. The method then expects you to Return a single scanResult out of the list of results of your choice so that it can try to connect to it. The rest is
pretty much the same.
You have two options to cancel a connection in progress.
- If Connection takes too long to complete and just hangs in there without calling back
onConnectionResultYou can specify a TimeOut in milliseconds.
WifiUtils.withContext(getApplicationContext())
.connectWith("MitsarasWiFi", "MitsarasPassword123")
.setTimeout(15000)
.onConnectionResult(this::checkResult)
.start();The Connection will fail in 15 seconds. The default timeOut is 30 seconds.
- You can also cancel an ongoing connection immediately using the following:
WifiConnectorBuilder.WifiUtilsBuilder builder = WifiUtils.withContext(getApplicationContext());
builder.connectWith("MitsarasWiFi", "MitsarasPassword123")
.onConnectionResult(this::checkResult)
.start();
builder.cancelAutoConnect();On Androids 5.0 and greater there is also an option to connect using WPS keys. This library makes it easier and safer to connect using WPS than the stock android API.
WifiUtils.withContext(getApplicationContext())
.connectWithWps("d8:74:95:e6:f5:f8", "51362485")
.onConnectionWpsResult(this::checkResult)
.start();You can disconnect from the currently connected network.
WifiUtils.withContext(context)
.disconnect(new DisconnectionSuccessListener() {
@Override
public void success() {
Toast.makeText(MainActivity.this, "Disconnect success!", Toast.LENGTH_SHORT).show();
}
@Override
public void failed(@NonNull DisconnectionErrorCode errorCode) {
Toast.makeText(MainActivity.this, "Failed to disconnect: " + errorCode.toString(), Toast.LENGTH_SHORT).show();
}
});You can also remove the saved wifi network configuration. On Android 10, this will just simply disconnect (as wifi configuration's made by WifiUtils are no longer saved). Notice: WifiUtils can't remove network configurations created by the user or by another app.
WifiUtils.withContext(context)
.remove(SSID, object : RemoveSuccessListener {
override fun success() {
Toast.makeText(context, "Remove success!", Toast.LENGTH_SHORT).show()
}
override fun failed(errorCode: RemoveErrorCode) {
Toast.makeText(context, "Failed to disconnect and remove: $errorCode", Toast.LENGTH_SHORT).show()
}
})If you want to receive some extra logging info coming from WiFi Utils you can enable its logging capabilities with WifiUtils.enableLog(true);
You can also choose to send the logs to your own custom logger.
WifiUtils.forwardLog(new Logger() {
@Override
public void log(int priority, String tag, String message) {
Timber.tag(tag).log(priority, message);
}
});Damn You are required to set a few permissions in order for this lib to work correctly :( Also please check this issue
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <!-- for Android 6 and above -->There are a few more things left to be covered in this tutorial. Hopefully I will improve upon this in the future.
Feel free to add/correct/fix something to this library, I will be glad to improve it with your help.
