I am new to building apps in Android Studio and Java in general. However, I have been following a course with CodeAcademy, but I have encountered an issue when trying to load certain images to the ImageView. However, the information found on the page and their support forums have been no help.
I have this ImageView in my activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>

In my MainActivity.java file, I have the following code:

}
// TODO 4-A: onAnswerSelected(int answerSelected) {...}

} else {

// TODO 3-H.i: uncomment after implementing displayQuestion(Question)
displayQuestion(getCurrentQuestion());
}
}
void startNewGame() {
questions = new ArrayList<>();
// TODO 2-H: Provide actual drawables for each of these questions!
Question question0 = new Question(R.drawable.img_quote_0, "Pretty good advice, and perhaps a scientist did say it… Who actually did?", "Albert Einstein", "Isaac Newton", "Rita Mae Brown", "Rosalind Franklin", 2);
Question question1 = new Question(R.drawable.img_quote_1, "Was honest Abe honestly quoted? Who authored this pithy bit of wisdom?", "Edward Stieglitz", "Maya Angelou", "Abraham Lincoln", "Ralph Waldo Emerson", 0);

questions.add(question0);

displayQuestion(firstQuestion);
}
Question chooseNewQuestion() {
int newQuestionIndex = generateRandomNumber(questions.size());
currentQuestionIndex = newQuestionIndex;
return questions.get(currentQuestionIndex);
}
int generateRandomNumber(int max) {
double randomNumber = Math.random();
double result = max * randomNumber;
return (int) result;
}
Question getCurrentQuestion() {
Question currentQuestion = questions.get(currentQuestionIndex);
return currentQuestion;
}
String getGameOverMessage(int totalCorrect, int totalQuestions) {
if (totalCorrect == totalQuestions) {
return "You got all " + totalQuestions + " right! You won!";
} else {
return "You got " + totalCorrect + " right out of " + totalQuestions + ". Better luck next time!";
}
}
}
And a third file, Question.java, has the following:
package com.codeacademy.unquote2;
public class Question {
int imageId;
String questionText;
String answer0;
String answer1;
String answer2;
String answer3;
int correctAnswer;
int playerAnswer;
public Question(int imageIdentifier,
String questionString,
String answerZero,
String answerOne,
String answerTwo,
String answerThree,
int correctAnswerIndex) {
imageId = imageIdentifier;
questionText = questionString;
answer0 = answerZero;
answer1 = answerOne;
answer2 = answerTwo;
answer3 = answerThree;
correctAnswer = correctAnswerIndex;
playerAnswer = -1;
}
public boolean isCorrect() {
return playerAnswer == correctAnswer;
}
}
Edit: Included the stack trace, it looks like it points to an issue where the image it tries to draw is too large? I believe this is in reference to the line in the acitivity_main.xml which reads as the following in the displayQuestion method:
questionImageView.setImageResource(R.drawable.img_quote_0);
