Remarks
Metrics about a Window, consisting of the bounds and WindowInsets.
This is usually obtained from WindowManager#getCurrentWindowMetrics() and WindowManager#getMaximumWindowMetrics().
After android.os.Build.VERSION_CODES#UPSIDE_DOWN_CAKE, it also provides density. <h3>Obtains Window Dimensions in Density-independent Pixel(DP)</h3>
While #getDensity() is provided, the dimension in density-independent pixel could also be calculated with WindowMetrics properties, which is similar to android.content.res.Configuration#screenWidthDp
float widthInDp = windowMetrics.getBounds().width() / windowMetrics.getDensity();
float heightInDp = windowMetrics.getBounds().height() / windowMetrics.getDensity();
Also, the density in DPI can be obtained by:
float densityDp = DisplayMetrics.DENSITY_DEFAULT * windowMetrics.getDensity();
