>From some other mail thread I found some good info :
There is protected Registrant mUSSDRegistrant in package
com.android.internal.telephony; in BaseCommands.java
There is code to process USSD Response from RIL (telephony / java / com /
android / internal / telephony / RIL.java)
2381 case RIL_UNSOL_ON_USSD:
2382 String[] resp = (String[])ret;
2383
2384 if (resp.length < 2) {
2385 resp = new String[2];
2386 resp[0] = ((String[])ret)[0];
2387 resp[1] = null;
2388 }
2389 if (RILJ_LOGD) unsljLogMore(response, resp[0]);
2390 if (mUSSDRegistrant != null) {
2391 mUSSDRegistrant.notifyRegistrant(
2392 new AsyncResult (null, resp, null));
2393 }
Message displayed at device screen
package com.android.phone; in class PhoneUtils
static void displayMMIComplete
