[mohankrishna]

Well explained, Thank you, please do more..!

Great tutorial.  I searched for quite a calculator tutorials, and yours is the only one that actually uses reusable code and not individual button assignments in MainActivity.java.  Great exercise!

Hi jeddy, there seems to be a small problem with your code.. All is well until you just click on the +, - buttons only once.. Try clicking them the 2nd time and the "total+= ..." gets executed in the "switch" statement..Hence making the total double everytime the user clicks the +, - buttons..
All said you have a wonderful video here..
Thanks & regards.

If you have a View sender error, make sure you are not writing in a method (like onCreate() in my case). Create a method num_Clicked in a class and it will be fine.

Is it possible to make the calculator (or any other program for that matter) work on IOS after finishing the programming?

I can only edit certain options in the properties menu of the buttons and onClick isnt one of them, what do i do?

I tried to run it as an android application and it gave the following error "No compatible targers were found. Do you wish to add a new Android Virtual Device?". I tried adding but it it requires me to add a sd card which i have no idea how to do.
