    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test_layout);
   }

   public class myPhoneStateChangeListener extends PhoneStateListener {
       @Override
       public void onCallStateChanged(int state, String incomingNumber) {
           super.onCallStateChanged(state, incomingNumber);
           if (state == TelephonyManager.CALL_STATE_RINGING) {
               String phoneNumber =   incomingNumber;
           }

Well, It's very easy just add the code below inside your myPhoneStateChangeListener's onCallStateChanged method

if(TelephonyManager.CALL_STATE_OFFHOOK==state) {
    // phone picked up
}
if(TelephonyManager.CALL_STATE_IDLE==state) {
    // either phone hanged up or ringing stopped
}

or you can refer to this solution

Alternatively, You can also use BroadcastReciever to check the state change.

public class PhoneStateReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();

        assert bundle != null;
        String phoneState = bundle.getString(TelephonyManager.EXTRA_STATE);
        Log.d("phoneCallReceiver", phoneState);

        if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE)) {
            Log.d("phoneCallReceiver", "phone hanged up");
        }
        if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            Log.d("phoneCallReceiver", "phone picked up");
        }
        if (phoneState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
            Log.d("phoneCallReceiver", "phone ringing");
        }
    }
}

Well thanks for this answer, but I need a connected state when a call is connected and the timer starts on phone – Robin Hood Jun 22 '22 at 07:15
EXTRA_STATE_OFFHOOK is not the state where call is picked up i tried – Robin Hood Jun 22 '22 at 07:22
@RobinHood try filtering the action inside `BrodcastReciever` using `Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())` – Sidharth Mudgil Jun 22 '22 at 07:30
ok i'll try this also – Robin Hood Jun 22 '22 at 07:32
@RobinHood If filtering action doesn't resolve your problem refer to this [gist](https://gist.github.com/ftvs/e61ccb039f511eb288ee) – Sidharth Mudgil Jun 22 '22 at 07:53
this one i already using – Robin Hood Jun 22 '22 at 07:54
@RobinHood there is no state for *call picked*, You have to *track* the state changed which can be done by the `BroadcastReciever` or `PhoneStateListener` – Sidharth Mudgil Jun 23 '22 at 14:55
then how the `Twilio` provides you a connected state. – Robin Hood Jun 24 '22 at 07:13

@RobinHood Yes, Twilio API provides connected states it also establishes connections. So if establishes connections it knows whether the connection is established or not. _And I said there is no state for call picked provided by android itself_ – Sidharth Mudgil Jun 25 '22 at 03:25
