How to detect phone service state

Question

I read about PhoneStateListener and its onServiceStateChanged callback. One of the possible service state values is STATE_OUT_OF_SERVICE that I need to detect.

Can I get the phone state information without instantiating a listener? In my application, I have no need to be informed punctually for each change on phone state but only need to test if the phone is offline (due to radio signal not available) at a certain moment.

What I would is a (pseudo) TelephonyManager.getServiceState() to call once that unfortunately I cannot find.

Answer 1

Use the ServiceState class, documented here .

Call the getState() function which returns the current state of the phone.
