App Core

A set of extensions for Kotlin and RX utilities for more comfortable development of android applications. This library is designed to combine often used functions in development and provide a convenient API for working with widespread, boilerplate tasks. Each project contains an utility package, so this project is called upon to replace it, as well as find a quick solution for everyday tasks. You can add the library completely or select only the modules you need.

See Getting Started for more information about how to start using this library.

Few samples:

Date extensions:

var sampleDate:Date = System.currentTimeMillis().toDate()
var formattedDate = sampleDate
                        .toStringWithFormat(CommonFormats.FORMAT_SIMPLE_DATE_TIME)

Fonts and Spans extensions:

var spannableText = someStingText.applyFont(context, "Roboto-Bold.ttf")

var spannableText = (someStringText.applySpanSet()
                      add font(getTypeface("Roboto-Bold.ttf")) toText "Digital"
                      and font(getTypeface("Roboto-Italic.ttf")) from start2 to end2
                      and relativeSize(1.8f) toText "revolution"
                      and foregroundColor(Color.GREEN) from start3
                      and absSize(28f.spToPx(context).toInt()) toText "we do.").build()

Intents:

  callIntent("+### ### ## ##").launch(context)

 selectContactIntent()
        .launchForResult(context)
        .subscribe(
           { rxResult:RxActivityResult->
                   doSomeThingWithResult(rxResult)
           },
           { 
             it.message.toString.showToast(contxt)
           })

Project Status

This project is currently in preview, and we are seeking feedback from the developers community. We are open to suggestions for improvements and new ideas. Please see the "How to Contribute" section if you would like to contribute.

During the preview period, the App Core APIs may change at anytime. Of course, we will try to minimize such changes, but if this becomes necessary, all the necessary migrations will be described in CHANGELOG When the project reaches a stable state, we will update it to version 1.0.0 (or later). For all new versions we will log changes in CHANGELOG.
