 ## Mock API
 Application shows data from Mocked API. This is a simple HTTP server started with app on device.
 All data are being served by AndroidStubServer library based on configuration files placed in assets/mock/ directory. If you want to see configuration of API go to config.json file.

-## Project setup
-This project uses [Retrolambda](https://github.com/orfjackal/retrolambda).
-If your build fails on `compileRetrolambdaDebug` or `compileDebugJavaWithJavac`
-please ensure that you have both Java 7 and Java 8 installed in your system. To be
-sure that they are found you may want to set `JAVA7_HOME` and `JAVA8_HOME`
-environment variables.
-
-For example on linux you can add those lines `/etc/enviroment/`:
-```
-JAVA7_HOME=/usr/lib/jvm/java-7-openjdk-amd64
-JAVA8_HOME=/usr/lib/jvm/java-8-openjdk-amd64
-```
-
-Alternatively you may set them in `gradle.properties` file.
-Examples are provided as comments in `gradle.properties` in [project build dir](gradle.properties) [[see more]](https://docs.gradle.org/current/userguide/build_environment.html).
