image size (drawable-hdpi/ldpi/mdpi/xhdpi)

Question

Study android, now I\'ve some images to put into drawable dirs (hdpi/ldpi/mdpi/xhdpi). I read a lot but again I don\'t understand. Which size should be an image for every di

Answer 1

Tablets supports tvdpi and for that scaling factor is 1.33 times dimensions of medium dpi

    ldpi | mdpi | tvdpi | hdpi | xhdpi | xxhdpi | xxxhdpi
    0.75 | 1    | 1.33  | 1.5  | 2     | 3      | 4

This means that if you generate a 400x400 image for xxxhdpi devices, you should generate the same resource in 300x300 for xxhdpi, 200x200 for xhdpi, 133x133 for tvdpi, 150x150 for hdpi, 100x100 for mdpi, and 75x75 for ldpi devices
