How to find if the device is configured as a portable hotspot

Question

I can't find in the doc how to retrieve if device is configured as a portable hotspot.

I've read How to detect if a network is (configured as) a mobile hotspot on Android? but I don't know if the feature has been implemented?

You can use below code to check if Tethering is enabled or not on your device:

private static Method isWifiApEnabledMethod;

public static boolean isWifiApEnabled(WifiManager wifiManager) {
    if (isWifiApEnabledMethod == null) {
        try {
            isWifiApEnabledMethod = wifiManager.getClass().getDeclaredMethod("isWifiApEnabled");
            isWifiApEnabledMethod.setAccessible(true); //in the case of visibility change in future APIs
        } catch (NoSuchMethodException e) {
            Log.w(TAG, "Can't get method by reflection", e);
        }
    }

    if (isWifiApEnabledMethod != null) {
        try {
            return (Boolean) isWifiApEnabledMethod.invoke(wifiManager);
        } catch (IllegalAccessException e) {
            Log.e(TAG, "Can't invoke method by reflection", e);
        } catch (InvocationTargetException e) {
            Log.e(TAG, "Can't invoke method by reflection", e);
        }
    }

    return false;
}

Don't forget to add below permission in AndroidManifest.xml

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

For the SO link mentioned above in question:

This feature is not available i.e. has not been implemented. For more information check this link where Google officially marked the status as Status: Won't Fix (Obsolete)

Hope this will help you. Thanks!
