android - getSize() giving me errors -

-

when 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, when implement getsize runtimeerror

point size = new point(); display.getsize(size); //error right here m_ndisplaywidth = size.x; m_ndisplayheight = size.y;

logcat:

this supports both older , 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; }
