I updated answer for Kotlin language    For Kotlin  You should call Window Manager and get metrics  After that easy way   val displayMetrics   DisplayMetrics   windowManager defaultDisplay getMetrics displayMetrics   var width   displayMetrics widthPixels var height   displayMetrics heightPixels      How can we use it effectively in independent activity way with Kotlin language    Here  I created a method in general Kotlin class  You can use it in all activities   private val T GET SCREEN WIDTH String    screen width  private val T GET SCREEN HEIGHT String    screen height   private fun getDeviceSizes activity Activity  whichSize String  Int       val displayMetrics   DisplayMetrics       activity windowManager defaultDisplay getMetrics displayMetrics       return when  whichSize           T GET SCREEN WIDTH - gt  displayMetrics widthPixels         T GET SCREEN HEIGHT - gt  displayMetrics heightPixels         else - gt  0    Error           Contact   canerkaseler

None of the answers here work correctly for Chrome OS multiple displays  or soon-to-come Foldables      When looking for the current configuration  always use the configuration from your current activity in getResources   getConfiguration    Do not use the configuration from your background activity or the one from the system resource  The background activity does not have a size  and the system s configuration may contain multiple windows with conflicting sizes and orientations  so no usable data can be extracted    So the answer is  val config   context getResources   getConfiguration   val  screenWidthPx  screenHeightPx    config screenWidthDp dp to config screenHeightDp dp
