Answer 1

Get an instance of WifiManager, then call isWifiEnabled()

WifiManager wifi = your_context.getSystemService(your_context.WIFI_SERVICE);
boolean wifiEnabled = wifi.isWifiEnabled();

You should be able to scan for networks using startScan(), then call getScanResults(). The scan results contain signal strength info for each network. For more see http://developer.android.com/reference/android/net/wifi/WifiManager.html

I think for GPRS you can get an instance of ConnectivityManager and ask for info on the mobile data connection:

ConnectivityManager cm = your_context.getSystemService(your_context.CONNECTIVITY_SERVICE)
NetworkInfo nw = cm.getNetworkInfo(TYPE_MOBILE)

This will tell you whether you have a data connection or not. I’m not sure how to get signal strength, but I’m sure you’ll figure it out if you read some of the docs:
