versionName String.format("%.0f.%d", versionCode / 16 + 0.49, (versionCode + 15) % 16)

在 String.format 的 %.0f 會把 1.5 四捨五入 為 2.0
(但 17/16+0.4 轉 %.0f 還是 1 ?!)

P.S. 17/16 = 1.0625

Glide 3.x & 4.x: DiskCacheStrategy.NONE caches nothing
Glide 4.x: DiskCacheStrategy.DATA, Glide 3.x: DiskCacheStrategy.SOURCE caches only the original full-resolution image.
Glide 4.x: DiskCacheStrategy.RESOURCE Glide 3.x: DiskCacheStrategy.RESULT caches only the final image, after reducing the resolution (and possibly transformations) (default behavior of Glide 3.x)
Glide 4.x only: DiskCacheStrategy.AUTOMATIC intelligently chooses a cache strategy based on the resource (default behavior of Glide 4.x)
Glide 3.x & 4.x: DiskCacheStrategy.ALL caches all versions of the image
