.NET developers like Xamarin because they can develop Android and iOS apps in C#. However, if you are not afraid of learning new programming languages, you’d better choose Kotlin for Android and Swift for iOS. Unlike React Native, Flutter and Cordova, with Xamarin, you cannot create one codebase for both platforms in Visual Studio. Moreover, when you try to bind a complicated and obfuscated Android library, you may be in big trouble. I just suffered from the pain of binding Dynamsoft Camera SDK for Android.
If you have a .jar or a .aar file for distribution, you can publish it to Maven central or jcenter. But the premise is your package has to be open source. If you want to distribute a commercial library, you’d better host a Maven repository yourself. Inspired by STEFFENWELLNER’s article, I have successfully set up a Maven repository on IIS. The post includes how to create an AAR project, how to configure IIS and URL, as well as how to create a testing project.
Dynamsoft Android Camera SDK is coming soon. In this article, let’s preview the SDK and learn how to write an Android document scanning app with a few lines of Kotlin code.
Last week I made a warm up for Kotlin, getting started to learn tutorials and reference. Now it is time to take the next step. Since Kotlin is hundred percent compatible with Java, we can use both programming languages without barriers in one project. In this article, I want to share how to build an Android barcode reader using Kotlin code and Java code.
Flutter, a framework developed by Google, aims to help developers build iOS and Android apps from a single codebase in Dart programming language. It is still an early-stage open-source project. The development environment only works on macOS and Linux (64-bit). I was curious about how Flutter performs comparing to Xamarin and Cordova, and thus, I got started with Flutter a week ago. When developing an Android app, you may need to use some third-party SDKs, which wrapped as *.jar, *.so or *.aar files. In this post, I will share how to link an Android aar file in Flutter project.
Dynamsoft aims to make barcode SDK available for all mainstream platforms, including Windows, Linux, macOS, iOS, and Android. There are many developers devoted to developing mobile barcode scanner app for iOS and Android platforms. To expedite the developing work, some of them may rely on a powerful detection and recognition libraries, like Dynamsoft mobile barcode SDK. In this post, let’s take a glimpse of how to use barcode SDK for Android to build Android barcode scanner with a few lines of code.
No matter whether you are a mobile developer of Android or iOS, your ultimate goal is definitely to publish your apps on Google Play or App Store. Before submitting apps for review, you need to attach some screenshots used for promotion. Furthermore, you can record screen video in order to make a deep impression. In this article, I will illustrate how to use free and commercial tools to record and edit videos for mobile apps on macOS and Windows.
