This repository contains example of using RxJava with Android to solve real-world problems. More exapmples will be adding day by day and you are also welcome to contribute. .combinelatest allows you to motinor the state of multiple observables at a single place. This example demonstrats the use of combinelatest to validate a basic form. In this example there are 3 input fileds for the form. The form will be valid if all those 3 fields are valid. If any input field is invalid, an error message will be shown against invalid input. We have 3 imdependent observables that observes the input changes. After an ecent is emited from all 3 inputs, the result is combined and the form is evaluted for validity.
