Android adjust by it self you can put separate image for different folder if you want to use different images for high resolution devices and other device  Otherwise just put in one drawable layout folder only for some images you can make 9-patch also   read here  you need permission in manifest for multiple screen support link   lt supports-screens android resizeable   true    false                     android smallScreens   true     false                     android normalScreens   true     false                     android largeScreens   true     false                     android xlargeScreens   true     false                     android anyDensity   true     false                     android requiresSmallestWidthDp  integer                    android compatibleWidthLimitDp  integer                    android largestWidthLimitDp  integer   gt

You can use sdp size unit instead of dp size unit  The sdp size unit is relative to the screen size and therefor is often preferred for targeting multiple screen sizes   Use it carefully  for example  in most cases you still need to design a different layout for tablets

Adding to  ud an  It is not a good practice to create different folders for layouts  Create your layout such that it works fine with all the screen sizes  To achieve this  play with the layout attributes  You only need to have different images for hdpi  mdpi and ldpi types  The rest will be managed by android OS

You can figure out the dimensions of the screen dynamically  Display mDisplay  activity getWindowManager   getDefaultDisplay    int width  mDisplay getWidth    int Height  mDisplay getHeight      The layout can be set using the width and the height obtained using this method

Beginning with Android 3 2  API level 13   size groups  folders small  normal  large  xlarge  are deprecated in favor of a new technique for managing screen sizes based on the available screen width  There are different resource configurations that you can specify based on the space available for your layout  1  Smallest Width - The fundamental size of a screen  as indicated by the shortest dimension of the available screen area  Qualifier Value  sw dp value dp Eg  res sw600dp layout xml -  will be used for all screen sizes bigger or equal to 600dp  This does not take the device orientation into account   2  Available Screen Width - Specifies a minimum available width in dp units at which the resources should be used  Qualifier Value  w dp value dp Eg  res w600dp layout xml -  will be used for all screens  which width is greater than or equal to 600dp   3  Available Screen Height - Specifies a minimum screen height in dp units at which the resources should be used  Qualifier Value  h dp value dp Eg  res h600dp layout xml -  will be used for all screens  which height is greater than or equal to 600dp   So at the end your folder structure might look like this  res layout layout xml -  for handsets  smaller than 600dp available width  res layout-sw600dp layout xml -  for 7    tablets  600dp wide and bigger  res layout-sw720dp layout xml -  for 10    tablets  720dp wide and bigger   For more information please read the official documentation  https   developer android com guide practices screens support html DeclaringTabletLayouts
