Explanation

Android's density-independent pixel ratios are: 3 (ldpi 0.75x), 4 (mdpi 1x baseline), 6 (hdpi 1.5x), 8 (xhdpi 2x), 12 (xxhdpi 3x), 16 (xxxhdpi 4x). These are the preferred scaling ratios for providing image assets. The 1:2:4:8 pattern is incorrect - Android uses 4:3 scaling increments, not powers of 2.
