J2ObjC vs Trigger.io: What are the differences?

Developers describe J2ObjC as "Java to iOS Objective-C translation tool and runtime used by Google Inbox to share 70% of its code across Android, iOS, and Web". J2ObjC is an open-source command-line tool from Google that translates Java code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java code to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as data access, or application logic) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. On the other hand, Trigger.io is detailed as "The simplest way to build amazing mobile apps using the best of HTML5 and native". You write your HTML5 code using the Forge JavaScript API which gives you access to native features such as the camera and contacts API.

J2ObjC and Trigger.io can be primarily classified as "Cross-Platform Mobile Development" tools.

J2ObjC is an open source tool with 5.47K GitHub stars and 771 GitHub forks. Here's a link to J2ObjC's open source repository on GitHub.

        What are some alternatives to J2ObjC and Trigger.io?
        React Native
        React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.
        Ionic
        Free and open source, Ionic offers a library of mobile and desktop-optimized HTML, CSS and JS components for building highly interactive apps. Use with Angular, React, Vue, or plain JavaScript.
        Xamarin
        Xamarin’s Mono-based products enable .NET developers to use their existing code, libraries and tools (including Visual Studio*), as well as skills in .NET and the C# programming language, to create mobile applications for the industry’s most widely-used mobile devices, including Android-based smartphones and tablets, iPhone, iPad and iPod Touch.
        Apache Cordova
        Apache Cordova is a set of device APIs that allow a mobile app developer to access native device function such as the camera or accelerometer from JavaScript. Combined with a UI framework such as jQuery Mobile or Dojo Mobile or Sencha Touch, this allows a smartphone app to be developed with just HTML, CSS, and JavaScript.
        PhoneGap
        PhoneGap is a web platform that exposes native mobile device apis and data to JavaScript. PhoneGap is a distribution of Apache Cordova. PhoneGap allows you to use standard web technologies such as HTML5, CSS3, and JavaScript for cross-platform development, avoiding each mobile platforms' native development language. Applications execute within wrappers targeted to each platform, and rely on standards-compliant API bindings to access each device's sensors, data, and network status.

        This is one of the most amazing open source projects out there. Tom and Kieth do an amazing job working with the developer community and quickly responding to questions and concerns. I was blown away by how solid the ported code was. What a life-saver and a ridiculously awesome tool.
