Possible Duplicate: It's possible to get outgoing call duration during call? I need to show real-time outgoing call duration. But I do not know when I should start timer. I must start when get answer from other side. I tried TelephonyManager.EXTRA_STATE_OFFHOOK -- but it's state is when I press call-button.. OFFHOOK is the state when call is placed. So we should be notified when the call is received. How can we get that? Can You help me? When I should start count outgoing time? Thanks upd.. I think this data produces mobile operator server. And this server return call-duration and current balance after each outgoing call . Maybe It's right? I can't find any solution, but after each call value of call duration will be stored in db. We can get it by CallLog.Calls.DURATION How this value populate field in db? android share|edit edited Sep 20 '11 at 21:56 asked Sep 18 '11 at 13:23 vovs 224214

Using a content Observer to listen Call Logs content URI if it changed: ContentResolver contentResolver = context.getContentResolver(); CallLogObserver mObserver = new CallLogObserver(new Handler(), context); contentResolver.registerContentObserver( Uri.parse("content://call_log/calls"), true, mObserver); This is your CallLogObserver: public class CallLogObserver extends ContentObserver { private Context context; public CallLogObserver(Handler handler, Context context) { super(handler); this.context = context; } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); Log.i(TAG, "CallLogs Onhange()"); try{ Cursor c = context.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, CallLog.Calls.DATE + " DESC"); if (c != null) { if (c.moveToFirst()) { int type = Integer.parseInt(c.getString(c .getColumnIndex(CallLog.Calls.TYPE))); /* * increase call counter for outgoing call only */ if (type == 2){ String number = c.getString(c .getColumnIndex(CallLog.Calls.NUMBER)); long duration = c.getLong(c .getColumnIndex(CallLog.Calls.DURATION)); Log.i(TAG, "numer = " + number + " type = " + type + " duration = " + duration); } } c.close(); } else Log.e(TAG,"Call Logs Cursor is Empty"); } catch(Exception e){ Log.e(TAG, "Error on onChange : "+ e.toString()); } } share|edit answered May 4 '12 at 8:51 Kevin
