Android-IFx
This library is deprecated. I recommend use petitviolet/Android-scaex instead.
This library for Android provides if-expression like Scala.
IFx enabled Java if-statement to return value.
Strongly inspired by jshosomichi/ifx.
How to Use

dependencies {
compile 'net.petitviolet.android:ifx:latest-version'
