This simple app turns your Android phone into a Random Number Generator App.
To use this app the user just clicks the 'Random Number Generator' app icon and they are taken right into the app. They are greeted with two top EditText areas labeled: Top line (min number), Bottom line (max number). Then a blank TextView area right below. Followed by a 'Generate Number' Button. The user clicks the top min area and a number keypad (typewriter) pops up. They use this for entering numbers in the top field.
Then they collapse the keyboard when they are finished and click the 'Generate Number' button. A number will appear above the button that is generated between the two numbers entered on top. Users can then click again to get another random number based off the original numbers or put in new entries and click the button again for another number range randomly selected number.
