I’m really not sure what I’m doing wrong at this point… im trying to vew data stored by the time picker – but every time I run the application I get force close errors.<\/p>\n

P.S.<\/p>\n

It appears the issue is stemming from Line 74 in View Country.java<\/p>\n

timeTv.setCurrentHour(result.getInt(timeIndex));<\/p>\n
