在Android中将＃作为dtmf发送

Question

I'm trying to make a call directly like this

String url = "tel:" +"029870125,198#";                              
Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse(url));

but the problem is that Android is sending 198 as dtmf , but the # is not being sent. Is there any special mechanism needed to send # as dtmf ?

Intent intentCallForward = new Intent(Intent.ACTION_CALL);                             
Uri uri = Uri.fromParts("tel", phoneNumber, "#"); 
intentCallForward.setData(uri);                                
startActivity(intentCallForward);
