Alerter - An Android Alerter Library, now in Kotlin!

This library aims to overcome the limitations of Toasts and Snackbars, while reducing the
complexity of your layouts.

General

With simplicity in mind, the Alerter employs the builder pattern to facilitate easy integration into any app.
A customisable Alert View is dynamically added to the Decor View of the Window, overlaying all content.

Install

Include the JitPack.io Maven repo in your project's build.gradle file

groovy
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}

Then add this dependency to your app's build.gradle file

groovy
dependencies {
implementation 'com.github.tapadoo:alerter:$current-version'
}

kotlin
Alerter.create([email protected])
.setTitle("Alert Title")
