Question

I’m a beginner in android.Can anyone give me a clear idea about ITelephony.aidl and how it can be used for blocking a call in Android?

Answer 1

Create a new package com.android.internal.telephony in your src folder
then create a new file (not class) in it with name ITelephony.aidl
paste this body in your file

package com.android.internal.telephony;

import android.os.Bundle;
    interface ITelephony {
        boolean endCall();
     void dial(String number);
    void answerRingingCall();
    }

then you will see in your gen folder a new package with an Itelephony.java name is created
and now your all problems get resolved
