I have a 20mb text file with 7 lines of text, then a space, then 7 lines of text, space, and so on.
I need an app that can load the file into memory, and has 2 screens.
First one is an input text box where I can type 9 letters, with a button saying search. The next screen should display the results, with a forward and back button to display each match of the 7 lines in the text file where it finds that 9 letter string. The 2nd screen also needs a reset button to take you back to the first screen. Pretty simple stuff! Search time needs to be under 5 seconds, which should be very easy.
