Why is AIDE with libgdx engine crashing while trying to load my images?

Question

I'm using AIDE on my phone to write this program using the libgdx engine. When I run the program it crashes almost instantly. I haven't had a chance to do much but I've narrowed the problem down to trying to load my own pictures. When I delete/disable the code "Texture(Gdx.files.internal("button_center.png"));" the program is able to run. The other image was preloaded on starting the project and doesn't present any issue. I've tried moving my image to the same folder to the image that works and refreshed the build, but the app still crashes.

Here's the code:

package pavlov.murderdoggyalpha;

import com.badlogic.gdx.*;
import com.badlogic.gdx.graphics.*;
import com.badlogic.gdx.graphics.g2d.*;
import pavlov.murderdoggyalpha.*;



public class MyGdxGame implements ApplicationListener
{
    Texture texture;
    Texture butDownLeft;
    Texture butLeft;
    Texture butUpLeft;
    Texture butDown;
    Texture butCenter;
    Texture butUp;
    Texture butDownRight;
    Texture butRight;
    Texture butUpRight;
    SpriteBatch batch;
    int touchX;
    int touchY;


    @Override
    public void create()
    {
        texture = new Texture(Gdx.files.internal("android.jpg"));
        butCenter = new Texture(Gdx.files.internal("button_center.png"));
        batch = new SpriteBatch();
    }

    @Override
    public void render()
    {        
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        batch.begin();

        batch.draw(texture, touchX, touchY, 
                   Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
            if (Gdx.input.justTouched());
            {
                touchX = Gdx.input.getX();
                touchY = Gdx.input.getY();
            }
        batch.end();

    }

    @Override
    public void dispose()
    {
    }

    @Override
    public void resize(int width, int height)
    {
    }

    @Override
    public void pause()
    {
    }

    @Override
    public void resume()
    {
    }

}

I believe this is the error log. I apologise in advance, I'm new at this.

This stood out to me:

Caused by: java.io.IOException: couldn't load pixmap 8bit only.

Murder doggy alpha? Really? Anyway, libgdx is having trouble loading your Button_center.png make sure your filename is correct and you have the correct file extension — Lucas B
There has to be something wrong with the file path then. Either filename, extension, or path. — Lucas B

After doing some digging by googling "Caused by: java.io.IOException: couldn't load pixmap 8bit only" I found that for some reason it has trouble loading 16bit png images. I didn't know how to change it into an 8bit image so I went to lunapics and swapped the file extension to a gif. The app runs fine now.

Why is AIDE with libgdx engine crashing while trying to load my images?
