query WiFi signal strength?

Android Processing

Is there a way to read a (or better several) wifis signal strength inside processing?

I found the WifiManager class on Android Dev ( http://developer.android.com/reference/android/net/wifi/WifiManager.html ) but I'm to new to all this to understand if processing can work somehow with those objects, too or if one would have to write a processing library on a lower code level. Maybe there already is a library for that?

in the GPS examples it seems to be as if it were just Android java objects imported, am I right or is there a step of implementation I dont see?

sorry for noobing around. just dont know where to start (or what exactly to ask for).

i tried the one below, but it gets me this:

"WifiInfo() is not public in android.net.wifi.WifiInfo; cannot be accessed from outside package"

on http://developer.android.com/reference/android/net/wifi/WifiInfo.html it says that at least the getRssi() method is public, the WifiInfo class also is. So what do I miss here?

// Imports
import android.content.Context;

import android.net.wifi.WifiInfo;

import android.os.Bundle;

String[] fontList;
PFont androidFont;

WifiInfo wifi = new WifiInfo();

// Variables to hold the current WIFI data
int RSSI = 0;

//-----------------------------------------------------------------------------------------

void setup() {
size(screenWidth, screenHeight);
background(0);
fontList = PFont.list();
androidFont = createFont(fontList[4], 35, true);
textFont(androidFont);

RSSI = wifi.getRssi();

text("RSSI"+RSSI, 20, 40);
}

//-----------------------------------------------------------------------------------------

void draw() {

}
