Shrinking your codes is always better and this tool will eventually help in this process efficiently. You can optimize this app for reducing the code size and develop a rich, vibrant, and innovative mobile app. However, you should always test the app after using this tool as it changes a few symbols in the app, which may hamper the experience of users.

2. More the smaller, more the better:

Being a developer, you should never underestimate the size of the app during the development process. This is one of the common mistakes that developers commit in rush of adding content or high-end graphics and a lot more. But if you want to target billions of audience, then keeping the overall size of the app small is crucial.

5. Squash out unused resources:

For this process, you can utilize android resource remover, which helps you clean out all the unused resources gathered in the project from Android Lint.

6. Elimination of debugging information:

We as a leading Android Development Company always recommend our android developers to eliminate the debug-related functionality from the application. This data is generally not utilized by Android to run the applications. Thus, removing it from the app is an ideal solution to save more space for your app.

7. Say no to duplication:

It is vital to make sure that you don’t hold any duplicated functionality file in your database; it will eventually lead to having unnecessary files in your APK. Being a developer, it is important to understand which APIs you are utilizing in the development process along with their functionality. There can be scenarios where one API is already doing the function of the second API.
