I want to create such an application in which i want to open a dialer with specified number during call.

I have successfully opened the dialer during a call with refrence of this LINK but not able to dial the number, and another issue is that code is not working above Android 2.2. is there any other way to make this working in all devices.

Code : 

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
ITelephony telephonyService;
telephonyService = (ITelephony)m.invoke(tm);

// Silence the ringer and answer the call!
telephonyService.silenceRinger();
telephonyService.answerRingingCall();
telephonyService.showCallScreen();
telephonyService.showCallScreenWithDialpad(true);

ERROR LOG:

Remove this line and your code should work:

telephonyService.silenceRinger();

That is an invalid call after Android 2.2.
