First app

Hi,

Last week I learned about Android functions and implemented a simple button app with 3 buttons.

Even though it does not has any use in outside world but it is good for learning.

App:

1. 3 buttons should be there.

2. Click 1st button 2nd button should go

3. Click 2nd button 1st button should go

4. Reset Button to reset all

Implemented successfully

Lessen learnt:

1. Relative Layout: it gives you path with respect to x and y axis.

2. Visibility: for setting button visible or invisible or to disappear

3. Button

4. Creating AVD

5. Toast: to display the message for a short interval

Issue Faced: 

While developing the app i created 3 button initially but when i executed it was showing only one button.

I got confused at that time but then i learned about relative layout and it worked.
