Fail to use local files on device

[marcopuppo]

I'm trying to develop an app that runs on android and I'm testing the application on an Android Yoga Book.

I've problems to create files from the stack.
Each time I try I get in the result "can't open file".

I have downloaded the attached example from "How do I read/write to files on Mobile?" in livecode lessons.
But also with this stack I always get the same error.

the code for the button of the example is:

Code: Select all

on mouseUp
   set the defaultFolder to specialFolderPath("documents")
   put field "write" into URL ("file:iphonetest.txt")
   answer the result
end mouseUp

I have added the "answer the result" line to check the error.

What i am doing wrong ?
App deployment configuration ? My android device misconfigured ?

If I try to use the button in live code on the Mac it works with no error.

Try it this way:

Code: Select all

    on mouseUp
       put specialFolderPath("documents") & "/iphonetest.txt" into tURL
       put field "write" into URL tURL
       answer the result
    end mouseUp

Now I'm getting

invalid URL:/data/user/0/com.marcopuppo.filehandling/files/iphonetest.txt

I can't understand why I get this error with Android.

In MacOs or Windows it works fine.

The keyword "file:" was missing in Jaques post:

Code: Select all

on mouseUp
       put specialFolderPath("documents") & "/iphonetest.txt" into tURL
       put field "write" into URL ("file:" & tURL)
       answer the result
end mouseUp

But for whatever reason, it looks like you don't have write permission in that folder, although you definitively should!?

Thank you

I have done the change to the instruction and the stack works once.

After that I try something on other stacks and now the stack is not working anymore. "Can't open file" again.

Maybe is something wrong in standalone settings.

Buongiorno Marco,

settings look fine, sorry, no brilliant idea in the moment...
Someone?

Hi Marco,

The attached stack works as expected for me on my Android phone, tested with LiveCode 8.1.3. Clicking the "Write" button returns empty in "the result", and clicking the "Read" button returns the contents of the field that were written to "specialfolderpath("documents")/iphonetest.txt"

Which version of LiveCode are you using?

Best,
Panos

I'm using 8.1.3 Business and 9.0.0 dp6 business.
I think is something related to the Yoga Book.

Best,

Marco

Hi Marco,

On Android this script works fine:

Code: Select all

on mouseup
       put "/mnt/sdcard/Documents/" & "phonetest.txt" into tURL
       put field "write" into URL ("file:" & tURL)
       answer the result
end mouseup
