Based on the code it has to be drawing text2 to the screen. You can also dump the event table to the console. Near the top of your program:
local json = require( "json" )
Then inside your listener:
--LISTENER PLUGIN ZIP local function zipListener( event ) local gruss = display.newGroup( ) local Text2 = "" print( json.prettify( event ) )
Then you can look at your console log and see what it’s outputting. Since it’s erroring on device, you need to look at the device’s console log. If you don’t know how to do that, please read: http://docs.coronalabs.com/guide/basics/debugging/index.html
