Android Get Screen dimensions from Service

I got the Screen Size by using the following from a activity,

Display display = getWindowManager().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 ScreenSize??

So i guess as far as i see, there is no way we can get the Screen size from the service. Wat i have done as of now is to start the activity atleast 1ce by default and store the actual screen size in pixels in the shared preferences. I use the shared preferences to get the value when the service starts.

Is this the only way it'll work out??? Cant we by any means get the screen size from the service??

Since getDefaultDisplay() now is depricated, this works (kotlin):

val window = getSystemService(WINDOW_SERVICE) as WindowManager
val width: Int = window.currentWindowMetrics.bounds.height()
val height: Int = window.currentWindowMetrics.bounds.width()

Try this:

WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);

DisplayMetrics displayMetrics = new DisplayMetrics();

wm.getDefaultDisplay().getMetrics(displayMetrics);

int height = displayMetrics.heightPixels;
int width = displayMetrics.widthPixels;

there totally is a way to obtain it from a service:

    WindowManager window = (WindowManager) getSystemService(Context.WINDOW_SERVICE); 
    Display display = window.getDefaultDisplay();
    int width = display.getWidth();
    int height = display.getHeight();

If you are starting the service on boot (or automatically any other way) then shared prefs is a good way. However, if the only way you start the service is thru calling Context.startService() then it actually makes more sense to just place an extra in the Intent that you use to start the service.

It worked for me!

DisplayMetrics metrics = getApplicationContext().getResources().getDisplayMetrics();
int width = metrics.widthPixels;
int height = metrics.heightPixels;

You only needed to get the context.
