I looked around the internet for correct dimensions for these densities for square images  but couldn t find anything reliable    If it s any consolation  referring to Veerababu Medisetti s answer I used these dimensions for SQUARES       xxxhdpi  1280x1280 px xxhdpi  960x960 px xhdpi  640x640 px hdpi  480x480 px mdpi  320x320 px ldpi  240x240 px

My understanding is that if you use a View object  as supposed to eg  android windowBackground  Android will automatically scale your image to the correct size   The problem is that too much scaling can result in artifacts  both during up and down scaling  and blurring   Due to various resolutions and aspects ratios on the market  it s impossible to create  perfect  fits for every screen  but you can do your best to make sure only a little bit of scaling has to be done  and thus mitigate the unwanted side effects   So what I would do is    Keep to the 3 4 6 8 12 16 scaling ratio between the six generalized densities  ldpi  mdpi  hdpi  etc   You should not include xxxhdpi elements for your UI elements  this resolution is meant for upscaling launcher icons only  so mipmap folder only      You should not use the xxxhdpi qualifier for UI elements other than the launcher icon      although eg  on the Samsung edge 7 calling getDisplayMetrics   density returns 4  xxxhdpi   so perhaps this info is outdated  Then look at the new phone models on the market  and find the representative ones   Assumming the new google pixel is a good representation of an android phone  It has a 1080 x 1920 resolution at 441 dpi  and a screen size of 4 4 x 2 5 inches   Then from the the android developer docs         ldpi  low   120dpi   mdpi  medium   160dpi   hdpi  high   240dpi   xhdpi  extra-high   320dpi   xxhdpi  extra-extra-high   480dpi   xxxhdpi  extra-extra-extra-high   640dpi      This corresponds to an xxhdpi screen  From here I could scale these 1080 x 1920 down by the  3 4 6 8 12  ratios above  I could also acknowledge that downsampling is generally an easy way to scale and thus I might want slightly oversized bitmaps bundled in my apk  Note  higher memory consumption   Once more assuming that the width and height of the pixel screen is represetative  I would scale up the 1080x1920 by a factor of 480 441  leaving my maximum resolution background image at approx  1200x2100  which should then be scaled by the 3 4 6 8 12  Remember  you only need to provide density-specific drawables for bitmap files   png   jpg  or  gif  and Nine-Patch files   9 png   If you use XML files to define drawable resources  eg  shapes   just put one copy in the default drawable directory  If you ever have to accomodate really large or odd aspect ratios  create specific folders for these as well  using the flags for this  eg  sw  long  large  etc  And no need to draw the background twice  Therefore set a style with  lt item name  android windowBackground  gt  null lt  item gt
