如何获取已发送短信的送达报告？

In my Application我正在使用发送短信SMS Manager。要检查消息是否已发送，我正在使用Toast。 代替Toast我想要得到SMS Delivery Report我正在尝试很多例子，但是，一个流程不显示递送报告，例如当我的代码中发送短信时我的余额为0时，我想找到当我的余额为0时短信发送失败的递送报告。

Code:

String phoneNo = phno.getText().toString();
String smsBody = body.getText().toString(); 
 //Selected Messages to report to 1909
{
             try
             {
                
                 SmsManager smsManager = SmsManager.getDefault();
                 smsManager.sendTextMessage(phoneNo, null, smsBody, null, null); 
                 Toast.makeText(getApplicationContext(), "SMS Sent to: "+phoneNo,Toast.LENGTH_SHORT).show();
             }                           
             catch (Exception e)
             {
                 //Error Occurred if No Messages Selected 
                 Toast.makeText(getApplicationContext(),"SMS failed, please try again later!",Toast.LENGTH_SHORT).show();
                 e.printStackTrace();
             }
             }
         
    }

 class deliverReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), sms_delivered,
                        Toast.LENGTH_SHORT).show();
                break;
            case Activity.RESULT_CANCELED:
                Toast.makeText(getBaseContext(), sms_not_delivered,
                        Toast.LENGTH_SHORT).show();
                break;
            }

        }
    }
