    DSL-JSON library

    DSL-JSON library

    High performance JVM JSON library

    Fastest JVM (Java/Android/Scala/Kotlin) JSON library with advanced compile-time data binding support. Java JSON library designed for performance. Originally built for invasive software composition with DSL Platform compiler. v1 core library was targeting Java6, while v2 targets Java8. So there is no need anymore for dsl-json-java8 project and instead, just dsl-json project should be referenced. From v2 only a single annotation processor is supported, which was previously in the java8 project. Joda and some other specific libraries were removed. If you still need converters for those types, you need to include them in your project.

    DeepLinkDispatch

    DeepLinkDispatch

    Annotation-based library for making deep link handling better

    Deep links provide a way to link to specific content on either a website or an application. These links are indexable and searchable, and can provide users direct access to much more relevant information than a typical home page or screen. In the mobile context, the links are URIs that link to specific locations in the application. At Airbnb, we use these deep links frequently to link to listings, reservations, or search queries. Android supports deep links through declaration in the Manifest. You can add an intent filters which define a mapping between deep link schemas and Activities. Subsequently, any URI with the registered scheme, host, and path will open up that Activity in the app. You can’t easily indicate the parameters that you would expect in the URI that you are filtering for. For complex deep links, you are likely to have to write a parsing mechanism to extract out the parameters, or worse, have such similar code distributed amongst many Activities.
