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.
When building mobile barcode scanning apps for Android or iOS, developers could either choose open source SDKs – ZXing and ZBar, or some commercial mobile barcode SDKs. If you are an Android developer and have installed Android Play Services SDK level 26 or greater, it is convenient to create Android barcode reader apps with Android Vision API as well. Since Google has released a demo on GitHub, we can learn how to construct a simple Android barcode reader from the source code. Let’s anatomize the code and try to build our own version.
When making third party libraries and SDKs for Android development, you could build so files, jar files, or aar files. I prefer providing aar files for distribution since aar file is a simple zip file which includes so files, jar files, and other resources.
If you are still focusing on Windows desktop development, it is time to migrate to IoT and mobile technologies that have a big boost in the near future. In this post, let’s take a glimpse of how to build C/C++ “hello world” program for Raspberry Pi and Android on Windows using GNU toolchain and NDK.
Last week, Android Developers Blog posted an article – An update on Eclipse Android Developer Tools. It announced that Google will end development and official support for the Android Developer Tools (ADT) in Eclipse at the end of the year. Many developers have been using Eclipse to develop Android applications with ADT for many years. Someone may be reluctant to get started with a new IDE from scratch, though, it is worth spending time on the new tool if it is more powerful and efficient than Eclipse. As Google said, they will deliver a great experience on a unified development environment and make developers productive. Since I’ve been playing Android Studio for a few days, I’d like to share my experiences.
Xamarin platform helps .Net developers to easily build applications for Android, iOS, Mac and Windows in C#. Let’s take a look at how to create our first Android demo with Xamarin in Visual Studio 2013.
