Libgdx: File not found Error "Internal" when opening external file
Here's a good one.
I am trying to open a file using external.
FileHandle dirHandel = Gdx.files.external("MyApps/skanectModel.g3db");
boolean isDir = Gdx.files.external("MyApps/skanectModel.g3db").exists();
I know the file is there, and the bool tells me that it actually is.
The main problem is that I am getting this error.
Caused by: com.badlogic.gdx.utils.GdxRuntimeException: Error reading file: MyApps/skanectModel.png (Internal)
I don't know why to do this, I am not looking for an internal file.
Out of curiosity, I created a file in my assets folder just like this assets/MyApps/skanectModel.png
one and the code works fine, also the app can be played on my android.
But ... I only need to be able to read external ones. I am creating a simple 3D view for some friends and I will send them 3D models from time to time.
Here is a copy of the code:

****** EDIT ***** Following a quick recommendation from MadEqua, this is how I applied the fix.
FileHandle dirHandel = Gdx.files.external("MyApps/skanectModel.g3db");
myT = new TextureProvider() {
@Override
public Texture load(String fileName) {
Texture result = new Texture(Gdx.files.external(fileName));
result.setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear);
result.setWrap(Texture.TextureWrap.Repeat, Texture.TextureWrap.Repeat);
return result;
}
};
myT.load("Myapps/skanectModel.png");
model = modelLoader.loadModel(dirHandel,myT);

After looking closely at the stack trace, it appears that the model file itself is being loaded as expected.
The problem occurs when loading model textures:

I believe libGDX is trying to load texture files from the wrong location (internal location, explaining the error it received).
I have never worked with libDGX model functions, but I think you should use this method: loadModel (FileHandle fileHandle, TextureProvider textureProvider)
and pass to TextureProvider
, which loads the texture file from an external folder. (and make sure the texture file is there).
It should be easy to implement a custom TextureProvider
one that does exactly that by looking at FileTextureProvider .

From their wiki
External file paths refer to the root of the SD card on Android, and to the current user's home directory on desktop systems.
and
Local files are stored relative to the application root or working directory on desktops and relative to the internal (private) storage of the Android application. Note that local and internal are basically the same on the desktop.
So, if your file is at the root of the project, you should use local, not external. Can you provide more information such as a test platform.
