Apps [ask] Making an application android

[tulangkering]

My plan will make android app chord guitar, so in the Android application that displays the guitar chord list
This looks like the illustration;
A B C D E F G H I J K L M N O P

so if a letter is clicked, it will display some of the artist or band,
then after that when clicked on one of the band, it will feature more new chord chord after chord was chosen

I am confused whether to use a database or not?,, what grabs from rss? or create your own database to accommodate the data chordnya profit ..

Please Help me, thanks before

I've moved this to the Application Development forum so our devs can have a look.
