Alert Dialog Box in Android

When I started learning how to create an application in Android I came across of idea to add quit button which allows our user to quit the program within our application in this article I will complete the functionality of our application Sum and Product Program in Android. I will added the alert or quit dialog box that will ask the user if the user want to quit or return to our program. The code is very simple and easy to understand I enjoy every moment of it working with this simple application program in Android I hope you will find my work useful too.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Sum and Product of Two Numbers in Android

I am very amassed with new developments in technology particularly in mobile phone to be specific Android application development. In this article I would like to share with you my first android application that I have written using Android Studio I called this application sum and product of two numbers in android what thus the program will do is to ask the user to give two numbers and then our program will compute the sum and product of the two numbers. This program is very simple I just stated learning android programming in couple of days it is more on self study on my part. I hope you will find my work useful.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

My mobile number here in the Philippines is 09173084360.
