GdxRuntimeException: Error reading file

I am learning and programming a game for android using libgdx and i have got stuck on this error for quite a long period of time. I have enclosed the following content

  1. The code.
  2. The command i used to access the asset.
  3. Screenshot that contains the error when i debug the code on android.
  4. Screenshot of my Package Explorer.
  5. All the possible combinations i tried to get the code working.

1.The Code

package com.me.mygdxgame;

import com.badlogic.gdx.Gdx;  
import com.badlogic.gdx.assets.AssetErrorListener;  
import com.badlogic.gdx.assets.AssetManager;  
import com.badlogic.gdx.graphics.Texture;  
import com.badlogic.gdx.graphics.Texture.TextureFilter;    
import com.badlogic.gdx.graphics.g2d.TextureAtlas;  
import com.badlogic.gdx.utils.Disposable;

public class Gameassetloader implements Disposable, AssetErrorListener {

public static final String TAG = Gameassetloader.class.getName();
public static Gameassetloader instance = new Gameassetloader();
private AssetManager assetManager;

/** Load the appropriate texture for the respective entities **/
public AssetCharacter boy;
public AssetRock rock;
public AssetShield shield;

/** singleton: prevent instantiation from other classes **/

private Gameassetloader(){}
public void init(AssetManager assetManager)
 {
    this.assetManager = assetManager;

    //set asset manager error handler
    assetManager.setErrorListener(this);

    //load texture atlas
    assetManager.load(Gameconstants.TEXTURE_ATLAS_OBJECTS,TextureAtlas.class);

    //start loading assets and wait until finished
    assetManager.finishLoading();

    Gdx.app.debug(TAG, "# of assets loaded:" + assetManager.getAssetNames().size);

    for (String a : assetManager.getAssetNames())
        Gdx.app.debug(TAG, "asset:" + a);

    TextureAtlas atlas = assetManager.get(Gameconstants.TEXTURE_ATLAS_OBJECTS);

    //enable texture filtering for pixel smoothing
    for(Texture t : atlas.getTextures())
        t.setFilter(TextureFilter.Linear,TextureFilter.Linear);

    //create game resource objects

    boy = new AssetCharacter(atlas);
    rock = new AssetRock(atlas);
    shield = new AssetShield(atlas);
}

public void dispose() { assetManager.dispose(); }


 @Override
 public void error(String fileName, Class type, Throwable throwable) 
  {
    Gdx.app.error(TAG, "Couldn't load asset' " + fileName + "'", (Exception)throwable); 
  }

}

2.The Command

 public static final String TEXTURE_ATLAS_OBJECTS ="gdxgame-android/assets/packed/packed.png";

3.Screenshot of Package Explorer http://i1294.photobucket.com/albums/b608/Abhishek_M369/PackageExplorer_zpsd2589ee2.jpg

4.Screenshot of Error log (Android DDMS) http://i1294.photobucket.com/albums/b608/Abhishek_M369/ErrorLog_zps8a4a68d9.jpg

5.All the possible combinations i tried

 "/gdxgame-android/assets/packed/packed.png";
 "gdxgame-android/assets/packed/packed.png";
 "/assets/packed/packed.png";
 "assets/packed/packed.png";
 "/packed/packed.png";
 "packed/packed.png";
 "/packed.png";
 "packed.png";

 public static FileHandle location = Gdx.files.internal("assets/packed.png");
 public static final TEXTURE_ATLAS_OBJECT = location.toString();

 //this caused shutdown of emulator
 public static FileHandle location = Gdx.files.internal("assets/packed.png");
 public static final TEXTURE_ATLAS_OBJECT = location.readString();

 // I even tried setting the build path of the asset folder as source folder
 // Also tried placing the image in the data folder.
 // Tried using the absolute path too , i.e Gdx.files.absolute("the absolute");
 // Tried passing the absolute path directly as string

Nothing seems to work for me.

The problem was very simple, the problem lied in the different versions of libgdx and the documentation. The answer explained below will solely confirm to libgdx version 0.9.8 only.

(Note: The usage of Texturepacker GUI was used to pack textures && not the method from the libgdx library)

First the "assetManager" had to be supplied with a file that contains the coordinates of the images which was a mistake here as i was supplying the packed image.

The GL20 should be able to parse NPOT images but it was unable to do so and the reason remains unknown so i had to pack the texture to a POT which was accomplished by selecting the POT options in the GUI. After doing this i was able to load the newly POT image easily with the following code 

/**Mention only the folder/file under the asset dir**/

public class Gameconstants { public static final String location = "packed/packed.txt" }

/**access the same using the following command**/

private AssetManager assetManager;
assetManager.load(Gameconstants.location,Texture.class);

This Answer may not be very convincing but it surely solved my problem.

Thank you to all who helped :)
