I'm about to start talking one of my major challenged skills, GRAPHICS!
I'm planning on creating a full screen Overlay, which will have a transparent middle section...
Due to the modern Screen Sizes in modern Devices, I was left wondering what should be the "default" picture size in pixels, so that the Image would look good in any device, any density..?
So I created a poll. (the values are in pixels, and density is 1)
If the background picture cannot be stretched, I would recommend to have the original bitmap with some "extra bits wide", as Android screens can have different aspect ratios (which can range from 1.333:1 to nearly 2:1), so on a particular device you can make the image fit vertically and can crop it horizontally depending on its aspect ratio.
No, but seriously, your Photoshop/Gimp project should be at least twice as bigger as the final output.
If I were you, I'd compose everything in 4K, and then output all 4 scaled down versions (1920.png, 1280.png, 960.png, 480.png).
Let your app measure the user screen and decide the most appropriate size to use.
To minimize file size when using photoshop, do not use the regular "Save" function.
Use "Save for web" instead.

I would use 2 bitmaps: 1 for low res devices, 2 for high and select it by code based on screen res.
In both cases the bitmap will be scaled, but I think in the best way possible.
