Types of App Development
There are two ways to develop applications for Android;
- Native – If you are targeting any one operating system and designing an app for it, then this kind of development is Native App Development. In Native application development we use Java, and Kotlin programming language. For example, if you are designing an app for the iOS operating system, then you use C-Objective or Swift programming language in it. And if you are designing an app for the Android operating system, then you use Java or Kotlin Programming Language.
- Hybrid – If you are developing this type of app which can work on multiple operating systems then this type of development is called Hybrid Development. In Hybrid application development we use Flutter, React-Native, or NativeScript programming language. In hybrid development the app you develop is coded only once after that we can test and run it on the different operating systems.
We suggest that if you want to become a good app developer then you should choose Native App Development because the performance of native app development is higher than hybrid app development and users get great experience in native app development. We get enhanced security in native applications and it is easier to test and debug.
Complete Roadmap for Android Development in 2022
Step 1: Choose a Laptops/PC
The very first step of your Android development journey is that you should have a laptop or PC. If you want to take your Android application journey to a good level, then you should have a good laptop or PC. You can take any operating system like Windows, Mac, Linux, etc.
You will need a laptop with these minimum requirements:

Step 2: Pick a Language Java Vs Kotlin
The very first step for you to become an Android developer is to choose a programming language, if you do not choose the right programming language, then you will not be able to do anything good in your Android developer journey. There are many types of programming languages in the market that can be used in app development, but you have to choose a good programming language and take your Android app development journey ahead.
Like we told you that you should choose native app development, in this you can choose between Java and Kotlin language, if you are confused about which language we should choose, then we clear your confusion.
