ERROR:
10-07 16:23:10.437: E/CursorWindow(13987): Bad request for field slot 0,-1. numRows = 3, numColumns = 4
first of all, provide the full stack not just the single line of error.
second, it's a good beginning if you removed the spaces out of the fields' names constants. it's just a bad idea to take spaces in strings that lightly.
