android - getSize() giving me errors - Stack Overflow

android - getSize() giving me errors - Stack Overflow: 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;
}

layout - Android: How to get screen dimensions - Stack Overflow

layout - Android: How to get screen dimensions - Stack Overflow: If you want the the display dimensions in pixels you can use getSize:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

If you're not in an Activity you can get the default Display via WINDOW_SERVICE:

WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();

Before getSize was introduced (in API level 13), you could use the getWidth and getHeight methods that are now deprecated:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight(); // deprecated
