App crashes when loaded after user presses back button

Question

I am writing one of my first apps where the idea is that user inputs a number into a getText, clicks a button which adds the users input to previous results and shows this to the screen. I've tried storing the data in SharedPreferences and it works when the user presses the home button and then comes back into the app, but the app crashes if they press the back button and then comes back into the app. Any advice?

public class Calc extends Activity {

int points = 0;

SharedPreferences data;
public static String filename = "Points";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    data = getSharedPreferences(filename, 0);

    points = data.getInt("key", 0);

    final TextView myTextView = (TextView) findViewById(R.id.mytextview);

    myTextView.setText("" + points);

    Button Button = (Button) findViewById(R.id.add);
    final EditText Edit = (EditText) findViewById(R.id.input);

    Button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int temp = 0;

            try {
                temp = Integer.parseInt(Edit.getText().toString());
            } catch (NumberFormatException nfe) {
                System.out.println("Could not parse " + nfe);
            }

            points = points + temp;

            if (points > 9999) {
                myTextView.setText("10000+");
            } else {
                myTextView.setText("" + points);
            }

            Edit.setText("");

            SharedPreferences.Editor editor = data.edit();
            editor.putInt("key", points);
            editor.commit();
        }
    });

}
}

Answer 1

Im guessing you have an image on your activity. Thats what

"05-19 03:24:15.223: E/AndroidRuntime(1120): Caused by: java.lang.OutOfMemoryError: bitmap >size exceeds VM budget

Try using a smaller image or refer to Strange out of memory issue while loading an image to a Bitmap object for an alternate solution.

I'd first recommend you remove your imageview to check if this is the problem. If the problem is rectified look at the solution in the link above.
