Does the other computer have Java installed?
Do you use variables in your call to size()?

There are other things that could be going wrong, but without more information, it is hard to tell.

Thanks for your kind reply ;)

Does the other computer have Java installed?
Yes, since it has Eclipse and Android SDK installed.

Do you use variables in your call to size()?
The following of this post is my modified script, and I copy the Data into the "application  window" after it exports.

The image shows the folder it has for the application --

Inside the Data folder --

I have to create the Data folder, otherwise it won't display in my main computer too, help is appreciated  ;)

Is the second computer running the same operating system as the first one?
If not, did you make sure to export the application for both operating systems?

A couple of notes:

• My folder structure begins with application.macosx, application.linux, and application.windows.
• The data folder (note: lowercase first letter) is located at this level, although it shouldn't be necessary...
• Your data folder contains a folder called models... try flattening the folder structure (and adjusting your code accordingly)
• Any of the libraries that you are using could be causing problems.
  

Hi, Calsign
Both Windows 7 OS.

Do you mean 'data' is the same level with ' application.windows', outside of it and not inside, like this :

[application.windows.
[data
[models ( inside is the object and its texture )

and yes, I did use Data, instead of data, will try to rename it. Also I tried to flatten the folders but doesn't seem to help either,  but will try some more to see if it works.

File path is such a trouble to start with for a beginner.  :p

cheers

models should be inside the data folder, but all of its contents should be moved up; in other words, the data folder contains all of your files, but no sub-folders. You'll have to do this before you export the application in order to account for changes to the path to your files.

And, yes, data (in mine, at least) is at the top level.

As far as I know, you don't actually need the data folder (in the exported folder), but its contents should be flat before export.

Hi,
After I lower-cased 'Data' as 'data', it can be seen in other computer now.
But if I moved the data folder away, it is blank again, so I wonder why the expert function can't do the job for me. I have to specifically create or add the data folder for the application to run normally, even in main pc where I build the app.
The drawback is I can remove the source but not the model / texture from the built app.

Thanks it is kind of solved to me ;)

Here is my further test result:

after export as application. windows
I have to add a ' data' folder along with lib and source ( where source can be taken away for  protection purpose )
in the 'data', I simply HAVE to put the target xxx.kmz, no need to add its model nor texture.

Then when I hit the .exe to run, the application will create the model and corresponding texture automatically, then I can view in other PC with this standalone app.

Also, client has to install Java to view the app.
