"Push Button Dial" is  my first Android application.

This app can be used to select and add favourite contacts quickly and then it allows to make a call to these contacts by just pushing a button.
Following steps describes the usage of this app:
1. Push button to add the contact
2. Push and hold the button for a while to modify and add another contact
3. After adding the contact just push button to make a call
4. Sort Button: To sort the contacts in alphabetical order
5. View Mode Button: Select this button if you want to view the number and then make a call. To cancel the view mode just push and deselect it
6. SMS Mode Button: Select this button if you want to send a message instead of call. To cancel the SMS mode just push it again and deselect it
7. Erase Mode Button: Select this button and select the contact to be erased
