Update to calculate the size of each URL array
1
2// UPDATED 3 SIZEOF NOW CALCULATES ELEMENTS (NOT BYTES)IN ARRAY
3// UPDATED 2 INCLUDE APP GENRES and URL SETUP ON OPENING OF APP
4// UPDATED 1 APP VERSION WITH VOLUME DISPLAY AND 60 CHAR URL
5
6// IF YOU HAVE PREVIOUS CODE VERSIONS YOU NEED TO REFLASH
7// IF YOU HAVE PREVIOUS ANDROID VERSION YOU NEED TO UNINSTALL IT
