So I'm almost done with my app for an android platform. My app basically stores data day by day according to what the user inputs in the app. I just came to realize that when the phone is restarted, turned off, or the app is cleared from active apps.....all the data stored on the app is gone!! :/ Is there anyway to prevent this from happening?

Hi Ferhan,
Nope

You have to store the data somewhere; and reload it on startup.

Code: Select all

on mouseUp
   put specialFolderPath("documents") & "/Data.dat" into tFile
   if there is a file tFile then
      put url ("file:" & tFile) into tData
      answer tData --show the contents of the file
   else
      answer "No data file located" --First run
   end if
end mouseUp

and reload it on startup.

Hey Simon,

yeah i figured....was hoping for a miracle haha..

hmm is it okay if you clarify the code you have written? I'm not too sure what's going on...what button is being pressed? and the content is a bit confusing...not quite sure what is happening. thank you

OK here it goes
put specialFolderPath("documents") & "/Data.dat" into tFile
This is where the files are stored on mobile, Data.dat is just a filename
if there is a file tFile then
put url ("file:" & tFile) into tData
Go get the file if it is there.

So you have a game with a high score
each time you score a point you add it to tData
Normally I'd say when you close the app write tData out to a file but for mobile I say just write it every time a score is made.
put tData into url("file:" & tFile) (tFile may be a global)

Do you see how it works now?

Edit oh... yes you'd look for the file on openCard or somewhere
