Want to make it easy for your new users to understand all the features of your app?
Here's how you can do it using jetpack compose in android.
This implementation is inspired by the TapTargetView which is useful for legacy views.
Full source code is available on GitHub as Intro Showcase View and you can also add this as a gradle dependency in your project.
Once you follow the 10 steps in this article, your final implementation will look like this.
Step 1: Add a feature and draw circles on Canvas
Step 2: Find LayoutCoordinates of a fab button and recenter circle.
Step 3: Blend the overlapped circle to set transparency
Step: 4 Add circle reveals animation to highlight the target
Step 5: Add texts to describe the feature
Step 6: Set offset of Texts
Step 7: Calculate outer circle radius
Step 8: change the offset of our outer circle
Step 9: Fix the outer circle center point for the Top and Bottom bar.
Step 10: Add circle reveals animation to our outer circle.

The difference between Kotlin vs Java.
Android has officially adopted Kotlin as the supported language.
Future of Android development will be change, developers should know the differences Kotlin vs Java.
Kotlin Android is introduced by Google to build interactive mobile applications.
This programming language helps developers to track each functional aspect of programming with accuracy.
Kotlin comes featured with a number of advantages that make it more preferable programming language by the developers.
After Google officially launched Kotlin, a lot of developers started taking interest in this new language that allows them to save hours of development time.
Infact, many developers have also started to learn about Kotlin open source libraries that help them build better Android apps than before.
Currently, Android Kotlin libraries are one of the hottest topics for all the Android developers as they want to explore different libraries so that they can to get huge help while developing apps.
Here’s the list of 6 awesome Android Kotlin Libraries shared by our one of our Android programmers who recently worked on an Android Kotlin project.
Kotlin allows you to define functions and properties at the top level of your files.
That’s a great feature, but it can cause some confusion when combined with the fact that all top level declarations are referenced unqualified from Kotlin.
This can sometimes make it difficult to tell what a function is when reading one of its usages.
If you have a function with the same name in a different package, it’s not obvious from looking at the call site which function is being called.
You can fully qualify the name of the function with the entire name of the package that it’s defined in, but given Java’s convention of very deep package names, that’s not ideal.

As of now, Kotlin targets Java and JavaScript and is executed on JVM.Kotlin has been developed taking inspiration from other programming languages like Java, Scala, Groovy, Gosu, etc .
The overall syntax of Kotlin, even though may not be entirely similar to Java, at its core, Kotlin is dependant on the existing Java Class library to get productive results for the programmers.What are some major advantages of Kotlin?Brevity:The language is based on JVM and on its functional language which greatly curtails the boiler plate code that is used by other programming languages.
While it still remains more readable and far more typesafe.
Secondly, language is more expressive and a functional one.
Performance:Kotlin delivers exceptional performance and miniscule runtime.
Interoperability:Kotlin is a mature language allowing for an interoperable application in an uncomplicated manner.Contemporary:Since it is a new, modern language which gives developers a fresh start when involved in Kotlin application development services.
