Try this function isLayoutSizeAtLeast int screenSize   To check small screen  atleast 320x426 dp and above getResources   getConfiguration   isLayoutSizeAtLeast Configuration SCREENLAYOUT SIZE SMALL    To check normal screen  atleast 320x470 dp and above getResources   getConfiguration   isLayoutSizeAtLeast Configuration SCREENLAYOUT SIZE NORMAL    To check large screen  atleast 480x640 dp and above getResources   getConfiguration   isLayoutSizeAtLeast Configuration SCREENLAYOUT SIZE LARGE    To check extra large screen  atleast 720x960 dp and above getResources   getConfiguration   isLayoutSizeAtLeast Configuration SCREENLAYOUT SIZE XLARGE

Thanks for the answers above  that helped me a lot  -  But for those  like me  forced to still support Android 1 5 we can use java reflection for backward compatible   Configuration conf   getResources   getConfiguration    int screenLayout   1     application default behavior try       Field field   conf getClass   getDeclaredField  screenLayout        screenLayout   field getInt conf     catch  Exception e           NoSuchFieldException or related stuff      Configuration SCREENLAYOUT SIZE MASK    15 int screenType   screenLayout  amp  15     Configuration SCREENLAYOUT SIZE SMALL    1    Configuration SCREENLAYOUT SIZE NORMAL    2    Configuration SCREENLAYOUT SIZE LARGE    3    Configuration SCREENLAYOUT SIZE XLARGE    4 if  screenType    1              else if  screenType    2              else if  screenType    3              else if  screenType    4              else      undefined

Couldn t you do this using a string resource and enums  You can define a string resource that had the name of the screen size  such as SMALL  MEDIUM  or LARGE  Then you could use the value of the string resource to create an instance of the enum     Define an Enum in your code for the different screen sizes you care about     public Enum ScreenSize       SMALL      MEDIUM      LARGE      Define a string resource  say screensize  whose value will be either SMALL  MEDIUM  or LARGE      lt string name  screensize  gt MEDIUM lt  string gt   Put a copy of screensize in a string resource in each dimension you care about  For example   lt string name  screensize  gt MEDIUM lt  string gt  would go in values-sw600dp strings xml and values-medium strings xml and  lt string name  screensize  gt LARGE lt  string gt  would go in sw720dp strings xml and values-large strings xml  In code  write ScreenSize size   ScreenSize valueOf getReources   getString R string screensize
