How to store some data in my stack

[吉野 孝]

Hi,

I use LiveCode 5.0.2 for Android devices.

I would like to store some data in my stack.
But I don't know how to store some data in my stack on an android device.

At first, I used a field. But the field data is gone at the next launches.

Next, I tried to use file.
The following are the  test scripts.

This is the 'write file' script.
on mouseUp
   put specialFolderPath(“documents”) & ":" & “testFile.txt” into fileName
   open file fileName
   write fld "Data" to file fileName
   put the result
   close file fileName
end mouseUp

This is the 'read file' script
on mouseUp
   put  specialFolderPath(“documents”) & ":" & “testFile.txt” into fileName
   open file fileName
   read from file fileName until EOF
   put it into fld "Data"
   close file fileName
end mouseUp

The scripts work on my Mac. 
But they does not work on an Android device.

I need your help.
