de.serialize(myobj, fos, true);

What am I doing wrong?

It's obviously unable to read anything from that file. Didn't you got a message in the log that tells you that uncompressed raw resources may not exceed 1mb in size?
Try to zip it and load it via a zipped inputstream you at least rename it to .zip or .mp3 so that Android thinks its compressed.

Like this?

Code Select Expand

Object3D obj = Loader.loadMD2(new ZipInputStream(con.getResources().openRawResource(R.raw.obj)), 1);

obj is Zip file.

Otherwise, Can you explain in detail.

Yes, like that. And i'm typing on the phone right now and for the next 10 days..i can't explain anything in detail right now.

[jumong]

but error still occur. Is there any idea?
Is there another method that load big serialized md2 file?

[EgonOlsen]

That is the right way to do it. It fails the first time it accesses your file to read the version number, so this is not a problem with the approach itself but with your file or your apk or whatever.
