Android Studio java.lang.ExceptionInInitializerError when static game assets are called to be drawn

Question

I've been working on a LIBGDX game for a while and last week I updated my Android Studio to Version 2.1.2. After the update I started getting the java.lang.ExceptionInInitializerError when the render method in the screen class tries to draw a static image which was called from a different class. " batcher.begin(); batcher.draw(Assets.rockWall, 0, 0, 160, 90); "

Here is my error log:

Android Studio shows no errors while compiling, how to solve this error?

Here is some code which is related to the error: Inside Assets Class:

public class Assets {

// The Rock Wall Background
public static Texture textureRockWall = new Texture(Gdx.files.internal("rockWall.jpg"));
public static TextureRegion rockWall = new TextureRegion(textureRockWall, 0, 0, 600, 450);
// The New Game Button
public static Texture textureNewGameButton = new Texture(Gdx.files.internal("newGameButton.png"));
public static TextureRegion newGameButton = new TextureRegion(textureNewGameButton, 0, 0, 139, 351);

Inside the StartMenuScreen Class:

public class StartMenuScreen implements Screen {

public void render(float delta) {

    // Draw Background Rock Wall
    batcher.begin();
    batcher.draw(Assets.rockWall, 0, 0, 160, 90); **// THIS LINE IS WHERE I GET THE ERROR. IF I REMOVE THIS LINE I GET THE SAME ERROR FOR THE NEXT STATIC OBJECT WHICH IS Assets.newGameButtonClicked...**
    //Screen1
    if(screen1) {
        if(!StartMenuScreenInputHandler.newGameButtonClicked) {
            batcher.draw(Assets.newGameButton, 50, 15, 15, 60);
        } else if(StartMenuScreenInputHandler.newGameButtonClicked){
            batcher.draw(Assets.newGameButtonP, 50, 15, 15, 60);
            if(goAhead){
                goAhead = false;
                StartMenuScreenInputHandler.newGameButtonClicked = false;
                buttonCounter = 0;
                screen1 = false;
                screen2 = true;
            }
        }

}

Hi nasch, I added the related code, since it would be too long to put more. Could you take a look at it again? Thanks a lot. — Oguzhan
This is the StartMenuScreen line 108: "batcher.draw(Assets.rockWall, 0, 0, 160, 90);" — Oguzhan
OK here's the problem, from your stack trace: Caused by: java.io.FileNotFoundException: trollWalk1.png — nasch
