getSize() giving me errors

Question

When I implement

WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE));
Display display = wm.getDefaultDisplay();
m_nDisplayWidth = display.getWidth();
m_nDisplayHeight    = display.getHeight();

I can run fine, but when I implement getSize I get runtimeError

Point size = new Point();
display.getSize(size); //Error right here
m_nDisplayWidth = size.x;
m_nDisplayHeight = size.y;

Answer 1

This supports both older and newer devices:

private static Point getDisplaySize(final Display display) {
    final Point point = new Point();
    try {
        display.getSize(point);
    } catch (java.lang.NoSuchMethodError ignore) { // Older device
        point.x = display.getWidth();
        point.y = display.getHeight();
    }
    return point;
}

Answer 2

Method to get Display Size for all devices:

private static Point getDisplaySize(final Display display) {
    Point point = new Point();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) { // API LEVEL 13
        display.getSize(point);
    } else {    
        point.x = display.getWidth();
        point.y = display.getHeight();
    }
    return point;
}

gettin Size:

WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE));
Display display = wm.getDefaultDisplay();
Point myPoint = getDisplaySize(display);    
Log.i("***Size X::", String.valueOf(myPoint.x));
Log.i("***Size Y::", String.valueOf(myPoint.y));

Answer 3

This version works for API < 4, too:

@SuppressWarnings("deprecation")
@TargetApi(VERSION_CODES.HONEYCOMB_MR2)
public static Point getSize(Display display) {
    Point point = new Point();
    if (sdkInt() >= VERSION_CODES.HONEYCOMB_MR2) {
        display.getSize(point);
    } else {
        point.set(display.getWidth(), display.getHeight());
    }
    return point;
}

@SuppressWarnings("deprecation")
public static int sdkInt() {
    return Integer.parseInt(VERSION.SDK);
}
