    void answerRingingCall();
    void silenceRinger();
 }
 private void disconnectPhoneItelephony(Context context)
 {
    ITelephony telephonyService;
    TelephonyManager telephony = (TelephonyManager)
            context.getSystemService(Context.TELEPHONY_SERVICE);
    try

    telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        Class<?> c = Class.forName(telephony.getClass().getName());
        Method m = c.getDeclaredMethod("getITelephony");
        m.setAccessible(true);
         telephonyService = (ITelephony) m.invoke(telephony);
        telephonyService.endCall();
    }

    }
} 

error:

(java.lang.ClassCastException:com.android.internal.telephony.ITelephony$Stub$
Proxy cannot be cast to belllab.com.meetingmanager.ITelephony )

Answer 1

telephonyService = (ITelephony) m.invoke(telephony);

This is not possible because m.invoke(telephony) does not return a sub class of ITelephony nor ITelephony itself, so you cannot cast it.

As you can see m.invoke(telephony) returns ITelephoney in com.android.internal.telephony package, but you are using ITelephoney in belllab.com.meetingmanager package.

Answer 2

If you have added ITelephony.AIDL file in your project? If not download from here and add it to your project.

You have to add the file like this

Also then your package name must be com/android/internal/telephony/ITelephony.AIDL:
