android - Get screen dimensions in pixels

I created some custom elements, and I want to programmatically place them to the upper right corner (n pixels from the top edge and m pixels from the right edge). Therefore I need to get the screen width and screen height and then set position:

int px = screenWidth - m;
int py = screenHeight - n;

How do I get screenWidth and screenHeight in the main Activity?

wManager().getDefaultDisplay(); But the same thing is not working from a service (for obvious reasons, i know!) but i desperately need to get the display size from a service. Can some1 please explain me any other way for getting the Screen

Instead of getSize and deprecated getWidth/getHeight combo (ignoring errors), try Balaji.K's getMetrics. Nik's comment in his answer even explains getDisplayMetrics to consider the system/status bar size. Also you may use density as jmaculate and LoungeKatt explained to have the EXACT value: DisplayMetrics dm = getResources().getDisplayMetrics(); float fwidth = dm.density * dm.widthPixels; Tested in Android v2.2 (API 8) and v4.0 with good results and no errors/warnings. –  Armfoot Sep 2 '14 at 10:32      DisplayMetrics displaymetrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(displaymet‌​rics); int height = displaymetrics.heightPixels; int width = displaymetrics.widthPixels; –  Azahar May 1 '15 at 5:30

This function returns the approximate screen size in inches.

public double getScreenSize()
        DisplayMetrics dm = new DisplayMetrics();
        int width=dm.widthPixels;
        int height=dm.heightPixels;
        int dens=dm.densityDpi;
        double wi=(double)width/(double)dens;
        double hi=(double)height/(double)dens;
        double x = Math.pow(wi,2);
        double y = Math.pow(hi,2);
        double screenInches = Math.sqrt(x+y);
        return screenInches;
