I wanted to develop a student app that possibly could be used by many teams (students from other schools)

I chose Ionic, because:

• single codebase: previously, we used React Native for Android and Angular for web/PWA, which was troublesome

• portability: runs on PWA (which is important, because iOS license is too expensive for school app), web, Android iOS (+ others, if needed)

• full use of web technologies: Next.js, Tailwind, React in this example (in oppose to Flutter/Java/Kotlin)

• stability and maintainability: low-entry level due to basic web technologies without new syntax (in oppose to React Native and Flutter), web is really stable and won't lose support (which doesn't have to be true with Flutter/Dart)

I've yet to see a non-native application that I felt performed as well and/or provided the same user experience with Cordova/PhoneGap/Xamarin. Frankly, at best they all seemed like underpowered web applications deployed to a sandbox that ran on a phone. They didn't feel "slick" or "mobile-first" and in some cases the performance was unacceptable. At previous companies, we built a few of these apps at the client's insistence, and in every case, they re-engaged us about 18 months later to re-write the app(s) natively.

We are doing some research on React Native and Flutter, but I am not yet convinced that they can provide the same level of experience and performance as native, though I am trying to keep an open mind.

As a startup, we need the maximum flexibility and the ability to reach our customers in a more suitable way. So a hybrid application approach is the best because it allows you to develop a cross-platform application in a unique codebase. The choice behind Ionic is Angular, I think that angular is the best framework to develop a complex application that needs a lot of service interaction, its modularity forces you (the developer) to write the code in the correct way, so it can be maintainable and reusable.

I've done some Hybrid Mobile apps with both technologies Apache Cordova and React Native and described my experience in my blog.

In a few words, I would suggest to use each technology in accordance what what is your current code base and what do you want to achieve.

React Native is a great option if you need that extra edge in performance with multi-threading and native UI rendering. Or you already have a web app based on React which you want to port to mobile.

On the other hand, if you have an existing web application code and you want to reuse some or all, including the ability to use web third-party libraries, then Cordova is the best option.

ProGuard is the most popular optimizer for Java bytecode. It makes your Java and Android applications up to 90% smaller and up to 20% faster. ProGuard also provides minimal protection against reverse engineering by obfuscating the names of classes, fields and methods.

I didn't find any plugins for it. So I've implemented it by myself and shared it on GitHub.

Feel free to use!
