I apologize for the simple question, but I am a bit confused.
I am creating my first Android app. Functinally I am done. I am now working on the UI. According to this, I am required to provide multiple icons to support different screens and I understand this part.
So I created a vector image, and was about to export it to generate a number of icons to support multiple resolutions. However, I could not find the require DPI. According to this, I am supposed to support different DPIs, but the article does not explain how to do that.
Can you please advise me on how to select the proper DPI? Does it even matter? I thought it does, but maybe my understanding is wrong.
Thanks.
EDIT:
Just to clarify my question. When I am exporting an image from a vector to a raster image, I have to select its dimension (so in my case, 400px X 200px), and its dpi. So what should I choose for DPI? Is that the same DPI that will create different icon sizes? I am confused. Thanks again.
I am writing my conclusion for the greater good. After further reading and investigation. It appears that DPI is not important when I am creating an image for a screen. So when I choose 400px X 200px, and assuming this will be for mdpi, then I should choose 800px X 400px for xdpi (and so on and so forth). The dpi should be ignored in all cases (does not matter if I chloose dpi of 90 or 600, as long as this is not for printing). On the other hand, if I am to print the image, then dpi is important.
EDIT
This is a great article about the topic. Please read it, it explains things very well.
