I'm not entirely sure what you're asking. If you're asking for a programming language that is good for developing Android applications, then Java and Kotlin are the most commonly used languages for Android development. Both languages have strong support from Google and the Android community, and they offer a wide range of libraries and tools that can help you build high-quality Android applications.

Java has been the traditional language for Android development for many years, and it's still widely used today. Kotlin, on the other hand, is a relatively new language that was specifically designed to improve upon some of the shortcomings of Java. It's gaining popularity quickly and is becoming the preferred language for many Android developers.

Ultimately, the choice between Java and Kotlin depends on your personal preferences and the specific requirements of your project. Both languages have their strengths and weaknesses, so it's a good idea to evaluate them carefully before making a decision.
