First of all , I am using android studio for development of android app. I have build an android app for OCR using tesseract library. The app is currently working great and giving desire output but my problem is with its size. The size of the build app is 30 MB which is high compared to other OCR app available. I have tried "minifyenabled = true" but it reduce just 300 kb of size. So my question is how to reduce size of my app?

Size of your android app plays a decisive role in application development where devices work on pay-by-the-byte plans. So, here are a few ways of reducing the size of your android app.

  1. Avoid using Pngs ( use vector images ) . Use pngcrush for compressing the png . Url: https://pmt.sourceforge.io/pngcrush/
  2. Try to get most of the images from a server rather than keeping them in source code.
  3. Use Dynamic Delivery concept to load on-demand features during runtime.
  4. Avoid using third party #libraries which can be done simply by a few lines of code.
  5. "Android Size Analyzer" this #plugin helps you in reducing the size of the app by giving you suggestions.
  6. Switch to Android App #Bundles from #APKs while publishing app or releasing updates. In this way , App is built based on CPU architecture (ABI), Language and Screen Density of the device. Documentation: https://developer.android.com/studio/build/configure-apk-splits
  7. Important : Set minifyEnabled and shrinkResources to true in your gradle.
