What is App Development?

App Development refers to the creation of computer applications for use on mobile devices such as tablets, smartphones and smart watches. Mobile device features such as cameras, motion and location awareness can be used to create unique and inventive mobile-only applications for things such as taxi and bike sharing.

Mobile devices typically have popular apps for searching, browsing and social media preinstalled and users can download and install additional apps from Google Play (Android) and the Apple App Store (iOS). Mobile applications are designed and built for different operating systems and developers will want to learn how to build for both the Android operating system and Apple’s iOS.

To learn android development from starting to become pro. You can follow these steps:

  1. Learn Kotlin (atleast basics) ( If you have no experience in Java programming or starting from scratch. else, You can continue with Java). My suggestion is to choose Kotlin as programming language for native android app development because Kotlin is official language since 2017 and all industries are shifting from Java to Kotlin for android development point of view.
  2. Now, Time to install Android Studio. It is official IDE( Integrated Development Environment) for native android app development.
  3. Get familiar with all Android Studio menus, controls and file structure. (Use 20–80 rules to starting you journey as a android developer)
  4. Learn about all basic views in XML and how to use them with best practices. How to modify and change the property of view at run time using Java and Kotlin program. (Learn about TextView, EditText, Button, LinearLayout)
  5. Learn about some more advance view and concepts like ListView, RecyclerView, ImageView and their implementations.
  6. Learn about Cursor, SQlite Database.
  7. Now, It’s time to check your learning. Develop some basic apps like todo app, note taking app using SQLite database.
  8. Learn about third party libraries for making life easier and saving your time.
  9. Learn implementations of retrofit, volley or okhttp to consume rest api for building networking app like social media, online note taking app, weather app etc.
  10. Learn, how to play video and audio and view PDFs.
  11. Learn advance concept like architecture pattern, costum view
  12. Congratulations, You are now a pro android developer.

These steps you can learn any time, you wish:

  1. How to build and generate apk and app bundle
  2. How to deploy on google play store
  3. Learn debugging
  4. Learn automated testing of android app
  5. Publish app on play store
  6. Build some cool and innovative projects and publish it.

Make sure to use Git / GitHub for version controlling, collaborating and remote working.

Note: It is my personal experience in android development. If you find anything wrong in this you can connect and message on discussion box .
