  • Create your own custom River of News out of feeds.
  • Read RiverJs format.
  • Read OPML and display them in an outline.

  • There is no login required to use any of the functionality.
  • There are no ads.
  • It is super fast.
  • It is efficient with data/battery usage.
  • It has the awesome Holo theme applied even from Android 2.2.

The website for this project is at http://rivers.silverkeytech.com. Android River can be downloaded at Google Store http://goo.gl/kShgp.

This code is licensed under GPL version 3. Please read license.txt.

I develop Android Rivers using Kotlin programming language version M8. It might not be obvious that this is Kotlin project since there are a lot of Java code in the project. Most of these Java code are open source libraries that Android Rivers include in source form by necessity. Most of the Kotlin code is located at NewsEngine module and com.silverkeytech.android_rivers package at the main project.

By reading Android Rivers source code, you will learn about:

  • Using SQLite database.
  • High performance XML parsing.
  • High performance JSON parsing.
  • Implementing a media player.
  • Writing Android Service.
  • Accessing Android Clipboard.
  • Fragments.
  • Implementing Holo theme in Android 2.2 above.
  • Using Library modules.
  • First class Outliner UI support.
  • Asynchronous operations.
  • Managing file system.
  • Creating custom dialogs.
  • Implementing Sliding Menu.
  • Asynchronous HTTP calls.
  • Integrating Android Java library.
  • Implementing Arabic language support.
  • Implement EventBus.

  • Fixed compilation for 'assignment in an expression context'

    Fixed compilation for 'assignment in an expression context'

    We prohibit things like val a = while(b) { ... } val b: Unit = c = 1 when statement appears in an expression context.

    For function not block body it has worked so far (it was a bug actually). This commit fixes a compilation.
