Compress APK for smaller file size

Question

The apk file size for my app is quite big. Is it possible to reduce the file size by using better compression level or different compression engine such as lzma (https://software.intel.com/en-us/android/articles/native-library-compression-sdk-for-android-apps)?

Answer 1

To simply answer your question:
Yes, use lzma.

Okay, now some other recommendations.

1. Build in release mode. This is very important, as the app size when built in debug mode can be a lot bigger than when built in release mode.
2. Compress your images. Often when making an app you don't really look at the size of images, and they usually tend to be the main issue concerning size. Simply opening them in, let's say paint.net, and saving them again with lower quality can help a lot.
3. Compress your audio files. Load them up in audacity and export them as MP3 with lower quality.

These are some small recommendations of mine. If you need your apk to be smaller still, I'd suggest trying google
