If you want 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;

This method was introduced in Android API 13, so if you want to get display metrics for previous APIs use:

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int wwidth = displaymetrics.widthPixels;

If you’re not in an Activity, you can get the default Display via WINDOW_SERVICE. Also be sure to set your minSdkVersion to at least 4 in AndroidManifest.xml to enable calls to display.getWidth().

WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

Edit: PhoneGap

Use the following to figure out the display size in pixels

 function getDeviceDimention() {
        console.log("Device Dimention using PhoneGap");
        console.log("Width = " + window.innerWidth);
        console.log("Height = " + window.innerHeight);
    }
