I am working on a WiFi intensive mobile application, where the code scans APs to connect and investigate them...
I'm using Android Studio and the emulators with it... After a lot of reading I came to conclusion, that can not access those APs from within the emulator, but have to use a real phone...
I'm looking for clarification on this...

What I have tried:

Lot of reading and searching for samples and possible extensions/updates...

"After a lot of reading I came to conclusion, that can not access those APs from within the emulator, but have to use a real phone.."

Have you looked at the AP called AndroidWifi?

That's an emulated AP (and only for very new API levels) - I try to look for real APs of real devices (I created)... On the real phone it works (with room for bugs), but on the emulator does not (even the host computer does see the APs)... I just wan't to be sure that I understood right that this is the case and didn't missed something small but valuable to me...

But it's an access point nonetheless. Your code to search for APs and connect to one would not change, whether it's an emulated one or a physical one right next to you.

The code to search for APs is there and working, but without a true device that can access calls behind that AP it is not much use, so AndriodWiFi is no use for me in this case...

I put together this code to run on my emulator, once with Wi-Fi turned off, and again with it turned on. It printed the correct results each time.

ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
if (cm != null)
{
    NetworkInfo ni = cm.getNetworkInfo(ConnectivityManager.TYPE_ETHERNET);
    if (ni != null && ni.isAvailable())
    {
        Log.d("Test2", "ETHERNET is available");
        if (ni.isConnected())
            Log.d("Test2", "ETHERNET is connected");
        else
            Log.d("Test2", "ETHERNET is not connected");
    }
    else
        Log.d("Test2", "ETHERNET is not available");

    ni = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
    if (ni != null && ni.isAvailable())
    {
        Log.d("Test2", "MOBILE is available");
        if (ni.isConnected())
            Log.d("Test2", "MOBILE is connected");
        else
            Log.d("Test2", "MOBILE is not connected");
    }
    else
        Log.d("Test2", "MOBILE is not available");

    ni = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    if (ni != null && ni.isAvailable())
    {
        Log.d("Test2", "WIFI is available");
        if (ni.isConnected())
            Log.d("Test2", "WIFI is connected");
        else
            Log.d("Test2", "WIFI is not connected");
    }
    else
        Log.d("Test2", "WIFI is not available");
}

Of course, I may just not be understanding your issue.

But have you seen any real device creating an AP? To test my code it is not enough to have a emulated WiFi network, but need actual connection to made to an actual device...

"But have you seen any real device creating an AP?"

The last three phones I've owned have had such a feature. I've only used it once, however. I had to enable the feature through their web site, and then I could turn it on at the phone.

We are going around and missing each other...
My request for clarification was about using an emulator to develop/debug/test a mobile application that connects real devices via WiFi...
You pointed out that there is an emulated WiFi (since API 25 IIRC), but even with that an emulator does not see any real device with AP... (I didn't asked for devices that create AP - I already have several ESP8266 powered things)...
Thank you for your effort to try and help me - I may conclude that my conclusion is right - I have to use a physical phone to develop such application...
