Tablet Layouts:

Use following folders if you wish to have tablet-specific layouts:

layout-large-mdpi   (1024x600)
layout-large-tvdpi  (800x1280)
layout-large-xhdpi  (1200x1920)
layout-xlarge-mdpi  (1280x800)
layout-xlarge-xhdpi (2560x1600)

Drawables folders:

1. Mobile

   res/drawable        (default)
   res/drawable-ldpi/  (240x320 and nearer resolution)
   res/drawable-mdpi/  (320x480 and nearer resolution)
   res/drawable-hdpi/  (480x800, 540x960 and nearer resolution)
   res/drawable-xhdpi/  (720x1280 - Samsung S3, Micromax Canvas HD etc)
   res/drawable-xxhdpi/ (1080x1920 - Samsung S4, HTC one, Nexus 5, etc)
   res/drawable-xxxhdpi/ (1440X2560 - Nexus 6,Samsung S6edge).
   

2. Tablet Resolution:
   

   Font Sizes:

NOTE: Always try to use SP whenever you deal with textSize, like textsize=12sp

1. Use predefined textAppearance:

   It will set text size automatically as per device density.

   <TextView android:textAppearance="?android:attr/textAppearanceSmall"/>
   <TextView android:textAppearance="?android:attr/textAppearanceMedium"/>
   <TextView android:textAppearance="?android:attr/textAppearanceLarge" />
   

   Sample usage:

   <TextView
       style="@android:style/TextAppearance.Small"
       android:text="Sample Text - Small" />
   <TextView
       style="@android:style/TextAppearance.Medium"
       android:text="Sample Text  - Medium" />
   <TextView
       style="@android:style/TextAppearance.Large"
       android:text="Sample Text  - Large" />
   

2. Use dimension.xml for each device:

   From Google IO Pdf, we see structure below:

   1. Mobile:

      res/values/dimens.xml(default)
      res/values-ldpi/dimens.xml   (240x320 and nearer resolution)
      res/values-mdpi/dimens.xml   (320x480 and nearer resolution)
      res/values-hdpi/dimens.xml   (480x800, 540x960 and nearer resolution)
      res/values-xhdpi/dimens.xml  (720x1280 - Samsung S3, Micromax Canvas HD, etc)
      res/values-xxhdpi/dimens.xml (1080x1920 - Samsung S4, HTC one, etc)
      

      res/values-xxxhdpi/dimens.xml (1440X2560 – Nexus 6,Samsung S6edge).

   2. Tablet:

      For tablet you can use more specific folder like values-xlarge, values-large.

      res/values-large/dimens.xml      (480x800)
      res/values-large-mdpi/dimens.xml (600x1024)
      

      or

      res/values-sw600dp/dimens.xml      (600x1024)
      res/values-sw720dp/dimens.xml      (800x1280)
      res/values-xlarge-xhdpi/dimens.xml (2560x1600 - Nexus 10")
      res/values-large-xhdpi/dimens.xml  (1200x1920 - Nexus 7"(latest))
      

For further information:

1. Refer to Supporting Multiple Screens.

2. See Page# 77 of Google IO Pdf for Design device density. In that, you will find the way to handle dimens.xml for different different devices.

Excerpt from Supporting Multiple Screens:

The density-independent pixel is equivalent to one physical pixel on a
160 dpi screen, which is the baseline density assumed by the system
for a “medium” density screen. At runtime, the system transparently
handles any scaling of the dp units, as necessary, based on the actual
density of the screen in use. The conversion of dp units to screen
pixels is simple: px = dp * (dpi / 160). For example, on a 240 dpi
screen, 1 dp equals 1.5 physical pixels. You should always use dp
units when defining your application’s UI, to ensure proper display of
your UI on screens with different densities.
