FileNotFoundException

Can someone explain a FileNotFoundException in android app? The documentation confuses me and I've looked at StackOverflow and this doesn't help me either. I have an android app where I keep getting this error and I think it's because I haven't specified the full path but I don't know how I would do this. Here is the code and I swear all the locations referenced exist. It worked fine until I added in the if and else statement that checked if it matched up.

public class GameActivity extends AppCompatActivity {

private Game game;
private ImageView gameImageView;
private TextView gameTextView;
private Button submitButton;
private TextView pointsTextView;
private int points;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_game);

    gameImageView = (ImageView) findViewById(R.id.gameImageView);
    gameTextView = (TextView) findViewById(R.id.gameTextView);
    pointsTextView = (TextView) findViewById(R.id.pointsTextView);
    submitButton = (Button) findViewById(R.id.submitButton);
    game = new Game();
    loadPage(0);
    specialCondition(0);
}


private void loadPage(final int pageNumber) {

    submitButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            specialCondition(pageNumber);
        }
    });

}

private void specialCondition(int pageNumber) {
    final Page page = game.getPage(pageNumber);
    if (pageNumber == 20) {
        startSubmit();
    }
    else if (pageNumber < 20) {
        Drawable image = ContextCompat.getDrawable(this, page.getImageId());
        gameImageView.setImageDrawable(image);
        String gameAnswer = getString(game.getPage(pageNumber).getAnswerId());

        String pageText = getString(page.getTextId());
        gameTextView.setText(pageText);

        String pointsText = String.format("%1$s", points);
        pointsTextView.setText(pointsText);

        String gameEditText = ((EditText) findViewById(R.id.gameSquare)).getText().toString();

        if (gameEditText == gameAnswer.toLowerCase()) {
            points++;
        } else if (gameEditText != gameAnswer.toLowerCase()) {
            points--;
        }

        int nextPage = page.getNextPage();
        loadPage(nextPage);
    }
}

private void startSubmit() {
 Intent submitIntent = new Intent(this, SubmitActivity.class);
    startActivity(submitIntent);
}

}

Hi Kenneth,

Would you be able to paste in the stack trace?

I'm not sure exactly what stack trace is but after looking it up I think it's this. If not just tell me what you're looking for:

I know this is really messy but I separated it the best I could.Thanks again for helping me last time and just tell me if you need something else.
