Nativscript getRootView() not working

In my root component I am trying to take screenshoot like this:

private getImage(v) {
        if (topmost().android) {
            const view = android.activity.getWindow().getDecorView().getRootView();
            view.setDrawingCacheEnabled(true);
            const bmp = android.graphics.Bitmap.createBitmap(view.getDrawingCache());
            view.setDrawingCacheEnabled(false);

            var source = new imageSource.ImageSource();
            view.source.setNativeSource(bmp);
            return source;
        }
    }

But I getting error that I cannot call getWindow function on undefined...

JS: ERROR TypeError: Cannot read property 'getWindow' of undefined

Anyone know how to do this?

use application.android.foregroundActivity or application.android.context. this will help you get reference to current activity. and then you can use 

    import * as application from "application";
    const view = application.android.foregroundActivity.getWindow().getDecorView().getRootView();
    view.setDrawingCacheEnabled(true);
    const bmp = android.graphics.Bitmap.createBitmap(view.getDrawingCache());
    view.setDrawingCacheEnabled(false);

here is playground demo link if you need it:https://play.nativescript.org/?template=play-ng&id=cmvjgq
