Block incoming calls

Question

my VoiP-client would like to block all incoming calls to the phone while my own call is taking place. Is it possible to do this somehow?

Answer 1

Not with the current SDK no, You can monitor incoming calls and give the user the option to answer with your application instead of the native app

How is the user offered to choose app to answer with, trough an intentchooser? Thanks for you help. – Pixie

Yep you can register to listen for that intent and start your application on that intent – Platitude

Answer 2

Yes you can block incoming calls. Using this code

 String phonestate = bundle.getString(TelephonyManager.EXTRA_STATE);

 try 
    {
        if (TelephonyManager.EXTRA_STATE_RINGING.equalsIgnoreCase(phonestate)) 
        {
            try 
            {
                TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
                Class c = Class.forName(tm.getClass().getName());
                Method m = c.getDeclaredMethod("getITelephony");
                m.setAccessible(true);
                telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);
            }
            catch (Exception e) 
            {
                e.printStackTrace();
            }

            if (prefStatus != null) 
            {
                if (count == 1) 
                {
                    telephonyService.endCall();
                    String prefLoginemail = myloginpref.getString("emailid", null);
                    System.out.println(printdata + " prefLoginemail :: "+ prefLoginemail);

                    Global.mNotificationManager = (NotificationManager) mxcontext.getSystemService(Context.NOTIFICATION_SERVICE);
                    notifyDetails = new Notification(com.CellPhoneTerror.R.drawable.icon1,"CellPhoneTerror!", System.currentTimeMillis());
                    myIntent = PendingIntent.getActivity(mxcontext, 0, new Intent(mxcontext, clsHomePage.class), 0);

                    notifyDetails.setLatestEventInfo(mxcontext,"You Got a Call from Blocked Number.", "",myIntent);
                    notifyDetails.flags |= Notification.FLAG_AUTO_CANCEL;
                    Global.mNotificationManager.notify(Global.SIMPLE_NOTFICATION_ID,notifyDetails);

                }
            }
        }
        if (prefIncomingBlock.equals("true")) 
        {
            if (TelephonyManager.EXTRA_STATE_IDLE.equalsIgnoreCase(phonestate)) 
            {
                if (count == 0) 
                {
                    System.out.println("if Cellphoneterror:"+ Global.clsIncomingNum);
                    Intent block = new Intent(context, dialogbox1.class);
                    block.setFlags(intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(block);
                }
            }
        }
    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }

Thanks.

-1 I think it is pretty that the asker wanted to know how to do this. – Stockdale

Sorry friends, But my network was down so I was not able to put example here. Anyway Thanks for comment. – Bobbery

How can you avoid the delay and sometimes one or two rings before its blocked? – Therefor
