Soooo my problem is, some PNG files i use are working on my desktop,
but everytime i export them to android, they get some error.

Now... WHY?^^

ummm yeah...
it looks like this on the desktop:



it looks like this on android:




i know the PNG is somehow "broken"? or...
i dont know what exactly the main cause is.

IT IS SOMETHING with the PNG file where android says: "NO I DONT ACCEPT THAT SHIT" and desktop says "thats fine enough"
because: its the image. not my code.

so yeah...
help pls^^

Android is case sensitive. Windows is not.

LoadImage ("pNG.png")

is not the same as

LoadImage("png.png")

Make sure you have defined your image files with the correct casing so android can accept it

So if your image in your media folder has the name.

CaPsOn.png

It needs to be LoadImage ("CaPsOn.png")

ha..

well i knew that android is case senstive and i knew the files were written correcty, in the code and in the data name.

But i never had thought it would be the ENDING of the data.
But the endings were invisible.
So
I had to turn the endings visible first.
and see that gimp exported my sprites with ".PNG" instead of ".png"
so
<MOD EDIT>
so
its Solved!


sooo
my file was:
"sprite.PNG"
and android wanted:
"sprite.png"



and

now im so happy i need a break
thanks

The case-sensitive filename issue has been covered many MANY times on the forums and continues to cause problems for people. I'd like to suggest a tweak to LoadImage so that by default it ignores case on all platforms, but has an optional parameter to switch case sensitive filenames on if you want. (something like: LoadImage( iImageIndex, sImageFilename, bBlackToAlpha, CaseSensitive ) where CaseSensitive can be 0 for off, 1 for on).

@paul
it would help if the debugger write a log at pc/ide if the load filename did not match the media filename.

It isn't AppGameKit that is case sensitive, it's the operating system. Having a flag in AppGameKit wouldn't work as the operating system is what's at fault. (Fault is a bad choice, as it's doing nothing wrong.)

I downloaded a mass file renamer which I run to rename every file in the media folder to lowercase before creating an apk. I'd suggest everyone else does too. Perhaps tgc should make it part of the apk process? I always put in any/all load media commands to load in lowercase, so having a tool to automatically run to make all files lowercase would suit me.

It is very simple to code around (use upper(string) when comparing the filenames?) and quite feasible to have a flag IMO. You may get an occurance of multiple files with the same name but different case which would cause a problem, but that's why you'd use the CaseSensitive flag (otherwise the first found would be used perhaps?).

Android is the most annoying platform in this regard. I tried to make everything case insensitive but the NDK doesn't provide a way to get a list of files in the APK media folder, so I can't compare them to the filename you are trying to load to find the correct file.

Oh I see the problem now Sounds like a challenge!

Can you get to the APK via /data/app and read it as a ZIP to get to the media folder?

I used to develop for Flash. Same exact problem with *.PNG vs *.png or even *.[ANYTHING_IN_CAPS] etc... Game breaking problems that are hard to find, but are really minor fixes, are the best! Just imagine if you didn't write ".PNG" in your initial question. It might have gone unsolved

Personally I would prefer if AppGameKit would just post a message "Cannot find image.png" instead of running like there wasn't a problem and showing that missing image image. Or at least show the message and then run.

Does SetErrorMode( 1 ) do this?

i think he's saying that the windows version could generate a message (in the log) when the case of the filename and the coded filename do not match (a very good idea i think)

not really, it will say file not found and you still wonder why.
and at pc there is no error message, only at mobile in this case.

@blink0k,that is exact what i mean.
