Scale factor for xxhdpi android?

android, android-screen-support

Solution

In android.util.DisplayMetrics, you can see that scaling factor is 0.00625:

/**
 * Scaling factor to convert a density in DPI units to the density scale.
 * @hide
 */
public static final float DENSITY_DEFAULT_SCALE = 1.0f / DENSITY_DEFAULT;

Where as DENSITY_DEFAULT is 160 --> scaling factor = 1.0f / 160 = 0.00625.

sizeScale = DENSITY_DEFAULT_SCALE * DENSITY_DPI

From this:

- ldpi = 0.00625 * 120 -> 0.75

- mdpi = 0.00625 * 160 -> 1.0

- hdpi = 0.00625 * 240 -> 1.5

- xhdpi = 0.00625 * 320 -> 2.0

- xxhdpi = 0.00625 * 480 -> 3.0

- xxxhdpi = 0.00625 * 640 -> 4.0

Not exactly a rocket science, but hope this will be useful for someone :)

Problem

according to http://developer.android.com/training/multiscreen/screendensities.html The following scale factors are mentioned xhdpi: 2.0 hdpi: 1.5 mdpi: 1.0 (baseline) ldpi: 0.75 I was wondering what the scale factor would be for xxhdpi?
