It\u2019s more modern and helps you write safer, less error-prone code compared to Java. While Java is still useful and widely used, Kotlin offers better features, has official support from Google, and allows developers to work more efficiently. While the decision completely depends on the needs of your project, Kotlin is generally seen as the better choice for creating forward-thinking, modern apps.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Can I make Android app using Kotlin?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Absolutely, you can use Kotlin to build Android apps.

To create a chat app using Android Studio, you need to create a project in the IDE, import the SDK dependencies into the project, integrate chat SDKs, and connect them to the server. This way, you can create an app that can send and receive messages within minutes. \"}},{\"@type\":\"Question\",\"name\":\"Can I build an Android App in Kotlin?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, you can create Android apps using Kotlin. It is an official programming language developed by Jetbrains with both object-oriented and functional constructs. Due to its easy-to-read , low code and null-safety capabilities, developers find Kotlin as a modern alternative to Java. In addition, Kotlin also helps coders to inter-operate it with other programming languages as it works on JVM (Java virtual machine). \"}},{\"@type\":\"Question\",\"name\":\"I am a complete beginner in Android Development & Kotlin. Can I start Android development in Kotlin? \",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, as a beginner, choosing Kotlin to build your Android app is an ideal decision. Kotlin is a concise programming language and it is easier to read. You can quickly understand the language and can build apps with fewer codes. This means, you can build apps in less time and spend less money for the development process, when compared to other languages. \"}},{\"@type\":\"Question\",\"name\":\"Should I use Android with Java or Android with Kotlin?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Kotlin is highly preferred for Android App Development than Java. Google\u2019s Kotlin-first approach and migration of its own tools, documentations and resources to Koltin features helped the giant witness a reduction in code-base size by 33% and NPE crashes by 30%. This stands as a proof of concept that Kotlin will be the future of Android app development, with Java alongside\"}},{\"@type\":\"Question\",\"name\":\"I want to build a chat app for Android within a month. Which API is easier?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"MirrorFly provides APIs that makes your app development easier and quicker. They offer low-code APIs - which means you need to write only a few lines of code to build a fully-functional chat app. Since this process will take only a few minutes, you will be able to build your app much faster than your expected deadline. \"}},{\"@type\":\"Question\",\"name\":\"Is it better to build out a chatting app with APIs like Mirrorfly, Apphitect, etc. or build out chatting from ground up?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"When you use reliable Chat APIs like MirrorFly and Apphitect with end-to-end encryption, it is easy to add interactive and secure chat features at low cost, within less than an hour. Whereas, when you build an app from scratch, it takes a huge amount of time and cost to complete the development process. Along with it comes the necessity to build and maintain a strong security infrastructure, demanding huge resources for the process.\"}}]} <\/script>\n\n\n\n<script type=\"application\/ld+json\">{\n  \"@context\": \"http:\/\/schema.org\",\n  \"@type\": \"CreativeWorkSeries\",\n  \"name\": \"How To Build An Android Chat App Using Java or Kotlin\",\n  \"aggregateRating\": {\n    \"@type\": \"AggregateRating\",\n    \"ratingValue\": \"4.7\",\n    \"bestRating\": 5,\n    \"ratingCount\": 64\n  }\n}<\/script>\n\n\n\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\/\", \n  \"@type\": \"HowTo\", \n  \"name\": \"Build An Android Chat App\",\n  \"description\": \"Developers assuming that you already know Java or Kotlin.
