A library to setup a backdrop component in your project since for now there is no a easy way to implement that in our project. Words from official material link: "A backdrop appears behind all other surfaces in an app, displaying contextual and actionable content". Here is an example of what you get using this library:

• Android API level 16 or greater
• Your favorite IDE

Current version:

Gradle:

Step 1. Add the JitPack repository to your build file. Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
		...
	}
}

Step 2. Adding Dependency

dependencies {
        ...
	    implementation 'com.github.pedromassango:IBackdrop:CURRENT-VERSION'
	    ...
	}

Maven:

Step 1. Register jitpack.io

<repositories>
	<repository>
	    <id>jitpack.io</id>
	    <url>https://jitpack.io</url>
	</repository>
</repositories>

Step 2. Add the dependency

<dependency>
    <groupId>com.github.pedromassango</groupId>
    <artifactId>IBackdrop</artifactId>
    <version>CURRENT-VERSION</version>
</dependency>

I wrote a step by step for how to use this library on Medium, follow the link: https://blog.usejournal.com/android-material-design-components-backdrop-96a3044a3b2

• Handle Device Orientation Changes (you can set it in your manifest's activity tag)
• Call Toolbar via XML (by reference)
• Set a custom animation duration
• Set a custom backdrop view size
• set Inactive state to front layer when the back layer is visible (grey the layer)
