Check the official documentation for explicit information.

Any android phone has one of this six screen densities. 

ldpi    Resources for low-density (ldpi) screens (~120dpi).

mdpi    Resources for medium-density (mdpi) screens (~160dpi). 
        (This is the baseline density.)

hdpi    Resources for high-density (hdpi) screens (~240dpi).

xhdpi   Resources for extra-high-density (xhdpi) screens (~320dpi).

xxhdpi  Resources for extra-extra-high-density (xxhdpi) screens (~480dpi).

xxxhdpi Resources for extra-extra-extra-high-density (xxxhdpi) uses (~640dpi).
        Use this for the launcher icon only, see note above.

Create icons of different sizes for different screen resolutions and put those icons to yourProject/app/src/main/res/drawable-mdpi or -hdpi or -xhdpi or -xxhdip folder.

I believe the issue here is that even though the tablet has high resolution, it still has low density due to its large screen size. So, the tablet is picking the image from low density folder which makes it look small on large scree.

The discussion here sheds some light on the issue. Basically you are required to create separate drawable folders for tablet's width. Ex. drawable-sw600dp and drawable-sw720dp etc.

Refer developer guide for more details.

  • can you please tell me the image size for drawable-sw600dp and drawable-sw720dp and where I want to create this folders – user1 Feb 06 '15 at 05:47
  • A 720p mobile will be classified as xhdpi so i think for sw720 you can use xhdpi resources and for sw600 hdpi resources should work. – Dhir Pratap Feb 06 '15 at 12:33
