How to compress apk size in unity3d

Question

I am making a simple test game in unity 3d using C #, the apk size of my game is 70 MB. I reduced the resolution of each sprite, but still 58 MB, how do I compress the game so that the apk file has the smallest possible size.

Answer 1

In addition to this short Unity tutorial , there are a couple things to keep in mind:

• Files that are not used or depend on them are deleted by Unity upon creation.
• Textures, music, and video take up most of the size. Sound files should ideally be .mp3format (otherwise .wavfor very short clips).

Most texture compression formats require an image with a resolution of 2 (128, 256, 512, 1024, 2048). Resolutions 4096 and 8192 may not work on some Android devices.

For example, an alpha-free texture in 1024x1024 resolution using RGB ETC2 compression takes about 0.5 MB in memory. A 1280x800 image with a 16bit RGB compression format takes 2 MB.
