Need help with file loading

Hello,

My loading and saving function works perfectly in the simulator, but fails on my Galaxy S5. Specifically, the game works fine on the first run, before anything is saved. Then, after I win a level, the game saves a higher value to the system file. After exiting the game and then opening it again, I get a black screen. I’ve pasted the code for my “main” file, which does the loading. I didn’t think it would be helpful to include the code in the “game” file that does the saving.

Thank you in advance for any insight.

local composer = require "composer" local myData = require( "annexoCodeFiles.annexoData" ) local json = require("json") local compPlayer = myData.compPlayer local unlockedLevels = {1,4} local jsonString = json.encode(unlockedLevels) -- Load Data -- Path for the file to read local path = system.pathForFile( "annexoFile.txt", system.DocumentsDirectory ) -- Open the file handle local file, errorString = io.open( path, "r" ) if not file then -- Error occurred; output the cause print( "File error: " .. errorString ) else -- Read data from file local preUnlock = file:read( "\*a" ) unlockedLevels = json.decode( preUnlock ) -- Output the file contents --print( "Contents of " .. path .. "\n" .. jsonString ) -- Close the file handle io.close( file ) end file = nil -- Save Data function saveData () -- Path for the file to write local path = system.pathForFile( "annexoFile.txt", system.DocumentsDirectory ) -- Open the file handle local file, errorString = io.open( path, "w" ) if not file then -- Error occurred; output the cause print( "File error: " .. errorString ) else -- Write data to file file:write( jsonString ) -- Close the file handle io.close( file ) end file = nil end saveData()
