Google project APK size too big

Hi,

When I build my game in unity I have an .apk 35mo and .obb 176mo but when I export for google project and build project without add any library, my .apk file is too large : 91mo

Why ? and How I can reduce size ?

Unity 4.2.2, on OSX

Thanks

 

I have same problem, my apk is 130mb and I don't know why, my game only has 3 scenes, with barely nothing...

 

I was able to reduce the file size of my apk from 130mb to 29mb, doing two things.
1 - Looked for folders called Resources, there was a big folder full of high res textures that were not being used, but since the folder name was Resources, they were imported into the final apk
2 - Reduced all texture max sizes from 1024 to 256 (this depends on your project of course, but in my case 256 is a aceptable size)

Check if any of those solutions help you
