 The Android UI framework defines a set of standard logical densities to help

+application developers target application resources. By default, device
+implementations MUST report only one of the following logical Android framework
+densities through the [DENSITY_DEVICE_STABLE]( https://developer.android.com/reference/android/util/DisplayMetrics.html#DENSITY_DEVICE_STABLE)
+API and this value MUST NOT change at any time; however, the device MAY report
+a different arbitrary density according to the display configuration changes
+made by the user (for example, display size) set after initial boot.
