Apps Saving graphics - how large?

[thomas12345678]

Hi,

I'm a graphic designer working with an Android developer.
Something's killing me. I simply don't know how big to save my graphic elements, since my computer screen has one resolution, my phone has another, other phones might have more or less resolution than mine, and don't forget about tablets.

I need the app to be able to run at both phones and tablets with different resolutions and graphic elements should be enlarged proportionally with the size of the screen - hope it makes sense. My developer tells me to make three versions of each element to put in folders called ldpi (small), mdpi and hdpi (large). I just don't know HOW small and HOW large in pixels. I'm not just talking about standard graphic elements such as menu, launcher icons etc. since our app will be very heavy with custom graphics. Do you guys just do the trial and error to check and see if it shows properly? And how can I guarantee that the app will show correctly on a tablet, without actually owning one ? ANY advise is much, much appreciated.

Best regards
Thomas

You need to go to this link and it will tell you exactly how the icons should look, including their size, shadows, etc.

Creat with hdpi (large) resolution using shapes. so you can resize any dimention and also you need to creat indivitual icons for different resolution.
