[Android] Larger apk file when Using ASTC Texture compression
ASTC Texture compression makes textures smaller thus build size should be smaller. This does not work when building for Android - apk size increases.
Steps:
1. Open attached project "repro.zip"
2. Make sure that all textures inside Assets/Textures have Format: RGB Compressed ETC 4 bits
3. Build for Android. Note: APK size is 9.2MB
4. Assets/Textures > select all textures > Set Format: RGB Compressed ASTC 8x8 block
5. Build for Android and check the apk size
Expected: APK size is smaller ( < 9.2MB)
Actual: APK size is 0.1MB larger ( = 9.3MB)
Reproduced with: 2017.4.37f1, 2018.4.18f1,
Not Reproducible with: 2020.1.0a25.
Note:
- after changing compression, also note that the size of each Texture has become smaller
- not reproducible on iOS:
RGB Compressed ETC 4 bits = 702.9 MB
RGB Compressed ASTC 8x8 block = 700.1MB
-not reproducible on Standalone: no ASTC compression option
-reproducible on both Mono and IL2CPP
