| Or would it be easier to take the plunge into developing an online database that folk could upload their data to that a HTML5 app could access... I know the whole nausea that could be entailed within the statement I nonchalantly made there (JSON, cheeky bit of mysql amongst other things) - I'd love to just access raw files that I've parsed on an Android device for local use. This seems like a good jumping off point: http://www.monkey-x.com/Community/posts.php?topic=8696&post=90465&view=all#90465 This is exciting.... [EDIT] Whilst I've initially achieved stuff quite quickly in HTML5, should I stop with my HTML5 and instead focus upon more Android esque dev? Or stay on the HTML5 bus for a while longer until I'm ready to hop on the Android dev bus? |

| Do you have an Android device for testing? By read/write a file you mean a local file system for single player? HTML5 supports saving and loading data locally too but not all the same filesystem features other targets support. What exactly are your goals? |

| Hi Soap, My goal is to read a .tcx file type, parse the data, store it in my own array(s) and plot some graphs. I'm carrying on with HTML5 development at the moment (still very early days) - I have an ASUS Android tablet for testing purposes - although the driver just failed to install for it which is of concern. Still, onwards and upwards. I suppose as an alternative to accessing a tcx file locally (which I intend to do for development purposes in the first instance) the aspiration maybe to access files remotely, say within a dropbox account. Ambitious I know.... |

| As far as I remember, for Android, you have to handle storage as one long string with SaveString and LoadString. Unless that has been changed during any recent updates of course. |

| Here's a loader class that I made quite a while back, I've used it in Flash and HTML5 targets so far, but I don't see any reason why it shouldn't work on Android. I will get around to adding a save method at some point when I feel the need to, but it shouldn't be too hard to do that yourself if you can't wait.
Class C_FileLoader
Field fileData:String[]
Field currentLine:Int
Method New(fileName:String)
fileData = LoadString(fileName).Split("~n")
currentLine = 0
End
Method ReadLine:String()
Local currentData:String
if Eof() = False
currentData = Self.fileData[Self.currentLine]
currentLine = (currentLine + 1)
Else
currentData = "Data Exhausted!"
EndIf
Return currentData.Trim()
End
Method Eof:Int()
if Self.currentLine > (fileData.Length() - 1)
Return 1
Else
Return 0
EndIf
End
Method LineCount:Int()
Return Self.fileData.Length()
End
Method ByteCount:Int()
Local bytes:Int = 0
Local line:Int
For line = 0 To (Self.fileData.Length() - 1)
bytes = (bytes + Self.fileData[line].Trim().Length())
Next
Return bytes
End
Method Empty:Void()
Local counter:Int
For counter = 0 to (fileData.Length() - 1)
fileData[counter] = ""
Next
fileData = fileData.Resize(0)
End
End

| If what I posted above don't work then look into SaveState and LoadState. You will have to handle things a lot differently with those commands though. |
