Android Apk Size

[Shadowarden760]

Good day!

I am using org.maplibre.compose:maplibre-compose:0.11.1 and material3 extension for special compose components in my project. After building release version I saw that my apk size became too big.

In apk-analyzer i saw that libmaplibre.so takes about 85% of my apk size.

Do you have any ideas how to reduce its size. Maybe there are some special options in building script which i can add or there will be optimizations in the future?

This is the native shared library for MapLibre Native: https://github.com/maplibre/maplibre-native.

The size you see is consistent with other apps using MapLibre Native. For example, I have Lyft installed on my phone and the libmaplibre.so is 12MB of that app.

There are multiple copies of the shared object in the apk, one for each architecture. When installed on a device, only the one relevant to the device architecture will be installed so the actual size of the app is smaller.

So, the only way to reduce apk size is to split it to different architectures in build.gradle, right?

splits {
        abi {
            isEnable = true
            reset()
            include("armeabi-v7a", "arm64-v8a", "x86", "x86_64")
            isUniversalApk = false
        }
    }

I believe so, yeah, though I'm not an expert on APK splitting and distribution.

If the binary itself can be further optimized for size, that work would happen in https://github.com/maplibre/maplibre-native. Though that's a larger and more mature project, so most likely any easy optimizations have already been done.

I see, thank you for the answer!
