It is working well on simulator but not on device.(newTableView issue)

[ashokry]

I’m using corona latest version - 2014.2445(windows)

But My app is working well on simulator but not on device(android).

this is my code piece. I’m not sure what’s wrong in line 321.

local tOption = {

left = 10,

top = 30,

width = display.contentWidth - 20, 

height = display.contentHeight / 24 * 23 - 50,

maskFile = “images/mask-320x448.png”,

onRowRender = onRowRender,

onRowTouch = onRowTouch,

}

list = widget.newTableView(tOption) — line 321

I got error message from adb log

Do you have any widget theme files laying in your folder with main.lua.

@ashokry,

Hi.  I think you’re seeing a lot of error messages that don’t have anything to do with the problem and it is confusing your debug effort.

Look through the error messages and focus on the ones that point to files in your project.  One that sticks out for me is:

I/Corona  (12587): F:\Work\Archive\calendarDetail.lua:321: in function ‘method’

Is that one of your project files?  If so, I’d look there and on that line to see whats going on.  

Often times, you’ll see errors mentioning files where no error occurred.  Corona is essentially unwinding the stack and those files and  functions were on it when the error occurred.

Hi, I also facing this problem. in simulator is ok, but on device there will be error occur as above

@uysuntray, what is the error you are getting?  Can you follow the backtrace back to where in your code you’re making a call?

@Rob, the error happen when i try to create new tableview (widget.newTableView), it always error on device, but in the simulator is working fine. I already test many with it and I am sure that widget.newTableView seem always making the error on device.

Can you please plug your device into your computer and capture the results from “adb logcat” and post the results here. If you need help with this, please read:

@Rob seem my computer configuration not working with the logcat, seem there something wrong with my PC, but the main point is widget.newTableView it always not working and error on device. but when i off that code on there no error happened.

If we can’t see the error, we can’t pin down the cause.  The #1 cause of “it doesn’t work on device” is a case sensitivity problem. Devices are case sensitive and the simulator is not. If your tableView is using images, make sure they match the case of the file name. In other words:

button.png and Button.png are different.

I already test with the code, there is no image in my tableview the code come as below.

local widget = require(“widget”)

local tableView = widget.newTableView{

}

just this 2 lines the error happen.

Awww thank you @Rob for your time, seem everything is fine now. it all my bad, the issue I forgot to delete all the widget theme.
