How to Develop an Android App

How to Develop an Android App

If you wish to learn the way Android apps are developed, you have got come to the appropriate place. Native Android apps must make the most of particular improvement instruments and programming languages to be able to maximize the capabilities of the native options current on Android gadgets. Native cell app improvement requires specialization, so whereas there are equivalencies when evaluating Android improvement to iOS improvement, Android app improvement is totally completely different and distinctive.

Android builders will make the most of instruments like Android Studio and Android SDK. The first programming languages used to develop Android apps are Kotlin and Java. Though, C++ will also be utilized in half to develop Android apps. Let’s take a more in-depth take a look at the programming languages and the event instruments used to create Android apps.

Native Android Programming Languages

Earlier than Android improvement can start in earnest, a programming language should be chosen. The language used to program the Android app might be a necessary a part of the app improvement course of. This selection must be made with the longevity of the app and the abilities of your builders in thoughts. Native Android improvement makes use of one among two programming languages:

  • Java
  • Kotlin


Up till only recently, Java was the official programming language of Android app improvement. Although Java is now not the official language promoted by Google for Android improvement, Java remains to be extensively used and closely supported by Google and the Play Retailer. Java has been round for a very long time. There’s a large on-line help group surrounding Java that helps builders discover solutions to troubleshoot issues and share suggestions, methods, and finest practices in terms of utilizing the programming language to develop cell apps.

The one draw back to Java is that for newcomers, this language could also be too complicated to adequately make the most of. Java makes use of a variety of completely different matters that newcomers might discover tough to grasp, together with:

  • Null pointer exceptions
  • Checked exceptions
  • Concurrency
  • Constructors

Moreover, Android SDK provides one other layer of complexity when used with Java. All issues thought-about, Java is a good programming language to make use of for Android app improvement, even when it’s a little tough to understand. Whereas Java is now not the official language of Android improvement, it’s nonetheless closely supported by Google and on-line communities. Builders can use Java to construct stunning, native Android apps.


Kotlin is the official programming language of Android improvement since Google determined this in 2019. The cool factor about Kotlin is that it’s interoperable with Java. This implies you possibly can add Kotlin code to your Java app and vice versa. If you wish to migrate your Java app to Kotlin, you are able to do it in levels as a substitute of all of sudden, because of Kotlin’s interoperability.  Kotlin additionally runs on the Java Digital Machine. Plus, whereas Kotlin is a local Android programming language, it’s also cross-platform, which suggests it may be utilized in different improvement initiatives and shared with iOS builders.

Kotlin is way less complicated than Java. This offers it a leg up in Android improvement. When in comparison with Java, Kotlin code is:

  • Shorter
  • Simpler to learn
  • Safer/safer

Kotlin’s benefits are due largely to its simplicity. Since Kotlin requires fewer traces of code, it’s simpler to learn, preserve, and safe. In brief, Kotlin is a contemporary programming language that’s designed to be easy and highly effective.

As we speak, Google estimates that about 60 p.c of the highest 1000 Android apps on the Play Retailer are made with Kotlin. Clearly, Kotlin is the way forward for Android improvement, however Java remains to be an essential a part of the dialog.

Different Languages

After all, you don’t essentially have to make use of Kotlin or Java to create an Android app. Nonetheless, you will want to make the most of extra frameworks and improvement instruments to be able to use different programming languages in Android app improvement. Android apps are additionally constructed with:

  • C++
  • Python
  • C#
  • HTML, CSS, and JavaScript
  • Rust

When you could also be extra comfy or aware of the programming languages on the record above, if you wish to create an ideal Android app, you must think about using Java or Kotlin.

What Growth Instruments are Used to Create Android Apps?

Now that you realize extra in regards to the programming languages utilized by Android builders, it is advisable study extra about the important thing improvement instruments used to be able to get an entire image of how Android apps are developed. The 2 most essential instruments in Android app improvement are:

  • Android Studio
  • Android SDK

Android apps might be created with out utilizing both of those instruments, however each of them, particularly when they’re used collectively, make creating Android apps simple. Plus, these instruments offer you entry to a variety of highly effective design and programming options that make Android apps extra highly effective and aesthetically pleasing.

Android Studio

Android Studio is the official improvement setting for constructing Android apps. This improvement setting provides builders the instruments to create apps for every type of Android gadgets. A number of the key options of Android Studio embrace:

  • Visible format editor
  • APK analyzer
  • Quick emulator
  • Clever code editor
  • Actual-time profilers
  • Versatile construct system

Visible Format Editor

The visible format editor in Android Studio provides builders the flexibility to tug, drop, and visually manipulate their Consumer Interface (UI). The supply code of the app is robotically up to date to mirror the visible adjustments that you simply make to your UI. Constraints enable Android builders to create beautiful, stunning Consumer Interfaces and be certain that they keep their spacing, sizing, and extra, even when the dimensions of the display or the system adjustments. The visible format editor in Android Studio additionally provides builders the flexibility to preview their designs on any system or display measurement.

APK Analyzer

Most apps have a variety of content material. If you could find a solution to scale back pointless content material, you possibly can enhance the efficiency of your app. The Android Studio APK Analyzer provides builders the flexibility to examine the varied content material of their app’s APK file even when their app was not constructed utilizing Android Studio. Builders may even use this instrument to check APK recordsdata between completely different variations of their app.

Quick Emulator

Google Studio’s emulator provides builders the flexibility to put in and run their apps on quite a lot of gadgets with out having to truly have a bodily system. This offers them the flexibility to check completely different app configurations and options earlier than they deploy.

Clever Code Editor

The clever code editor characteristic current in Android Studio helps builders work rapidly, extra effectively, and write higher code. Consider this characteristic like autofill or autocorrect. The clever code editor helps Kotlin, Java, and C++. This characteristic acknowledges the code getting used after which autocompletes instructions by giving builders an inventory of prospects to select from after they start typing.

Actual-time Profilers

The Android Studio comes loaded with instruments that present real-time statistics in your app’s CPU, community exercise, and reminiscence. This offers Android builders the flexibility to investigate incoming and outgoing community payloads, determine efficiency bottlenecks, and far more. Actual-time knowledge insights are a vital instrument that can be utilized to optimize efficiency and Consumer Expertise.

Versatile Construct System

The construct system in Android Studio is powered by Gradle. Android builders can customise their construct and create a number of construct variants from a single improvement mission. This skill permits builders to maintain all of their initiatives organized and centered with out having to account for variant builds for every system.

Android SDK

Android SDK is a software program improvement package that was developed for the Android Studio. It comes totally built-in with Android Studio and is continually up to date as new Android updates are rolled out. Nonetheless, you may additionally use Android SDK independently of Android Studio. This package features a assortment of software program improvement instruments and libraries that include all the pieces essential to code and take a look at Android apps.

Most Android builders use Android SDK and Android Studio collectively. Why? Android SDK was optimized to be used in Android Studio. These two improvement instruments had been constructed to work nice collectively. Moreover, Android SDK in Android Studio will get robotically up to date with the most recent Android OS releases, and because of Android Studio’s clever code editor characteristic help for Java, Kotlin, and C++ is dealt with robotically too.

If you’re already utilizing Android Studio, it is extremely simple to put in Android SDK instantly out of your improvement setting.
