android apk size not getting much smaller

Hi,

Then I built my app for android final package of the app had like 20.1 MB. I mean the APK file.
I checked unity editor log to see what files were taking most when unity was packing the project.
I found on first 5 places 3 fonts like 2,5 MB each and 2 textures that were like 700kB each.
So I made font to use my own defined characters instead of UTF8 and that made them significantly smaller like 500k or so.
And textures I made half resolution so they ended up like 250kB.
So after this I expected final APK to be smaller 6MB.
But instead the resulting APK was like 19.5 MB.
I double checked editor output and these resources indeed were much smaller.
Why is this difference in end package so small?
is there some heavy compression happening after what is logged in editor log as info what is size of each resource?

Thanks

you should try Stripping Level from playerSetting option.
Also check you image Resolution 1024x1024 it will help you to reduce image size.
And delete unused data from your project folder.
