How to reduce APK size in Android?

There are several ways to reduce the APK size in an Android app:

  1. Optimize images: Images often make up a significant portion of the APK size. You can use image optimization tools to compress images without sacrificing too much quality.
  2. Remove unused resources: Many times, apps contain resources that are not used. These unused resources can be removed from the APK, which can significantly reduce the APK size.
  3. Use ProGuard: ProGuard is a tool that can be used to remove unused code and optimize the remaining code. This can result in a smaller APK size.
  4. Use Android App Bundle: Android App Bundle is a publishing format that uses Google Play’s Dynamic Delivery to generate and serve optimized APKs for each user’s device. This can significantly reduce the APK size by serving only the required resources for each device.
  5. Minimize dependencies: Keep the number of dependencies to a minimum. Each dependency can add size to the APK, so use only the necessary dependencies.
  6. Use vector graphics: Vector graphics are smaller in size than raster images and can be scaled to any size without losing quality.
  7. Use compression techniques: You can use compression techniques such as Gzip or Zopfli to compress your assets and resources, which can reduce the APK size.

By following these tips, you can significantly reduce the APK size of your Android app, which can improve the user experience by reducing download times and saving device storage space.
