cloned the repo and gradle build fails :(

Error:Unable to load class 'org.apache.commons.lang3.StringUtils'. Possible causes for this unexpected error include:

• You are using JDK version 'java version "1.7.0_71"'. Some versions of JDK 1.7 (e.g. 1.7.0_10) may cause class loading errors in Gradle. Please update to a newer version (e.g. 1.7.0_67). Open JDK Settings
• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

Not too sure if the View Model was the best place to put this, but I've added the minimum amount of code needed to get it working.

I originally had the toolbar colour set as the theme's primary colour, however, the colour of the status bar is then set to a darker colour than the rest of the app, which looks very odd.

I get this error and i can fix that:

As you can read in the documentation NotifyDataSetChanged

RecyclerView will attempt to synthesize visible structural change events for adapters that report that they have stable IDs when this method is used. This can help for the purposes of animation and visual object persistence but individual item views will still need to be rebound and relaid out.

If you are writing an adapter it will always be more efficient to use the more specific change events if you can. Rely on notifyDataSetChanged() as a last resort.

I implemented NotifyItemInserted for when a new item is added and NotifyItemChanged for when an item is updated (that's not happening right now but could in the future).

I've update a lot of things

• Retrofit 2
• OkHttp 3
• Fixes on unitTests
• Updated gradle plugin and ...

With this changes u can easily clone this repository and just import it to AS without any headache.
