Which Android uses Java or JavaScript?

With the development of mobile Internet, mobile phones have become an indispensable tool for people. The popularity of Android system has become the first choice for mobile phone development. In Android development, we often hear the terms Java and JavaScript. So, does Android use Java or JavaScript?

First of all, Java and JavaScript are essentially two different languages. Java is an object-oriented programming language that is widely used in server-side program development, enterprise application development, desktop program development, and mobile application development. JavaScript is a script programming language, mainly used for interactive effects, dynamic effects, data transmission, etc. on the Web front-end.

In the Android system, Java language is mainly used for development. This is mainly due to the fact that the Android system itself is developed based on the Java language. In Android development, the Java language plays a very important role. From the perspective of the Android system architecture, the Android system consists of four levels: Linux kernel, middleware, application framework and applications. Among them, the middleware layer and application framework layer are developed and composed by Java language. Therefore, to become an excellent Android developer, it is very necessary to master the Java language.

So, what is the role of JavaScript in the Android system? In the Android system, although the Java language is mainly used for development, we often see some Web pages in applications, and these pages are usually written in three languages: HTML, CSS and JavaScript. Because in Android development, in addition to developing local applications, you also need to interact with the Web, such as obtaining data from Web pages. At this time, you need to use a scripting language like JavaScript. The main place where JavaScript is used in Android development is in Webview, which is a browser control in Android. For code running in Webview, JavaScript can be used for interaction and control.

In summary, in Android system development, Java is the main language used, and JavaScript is an auxiliary language. In future Android development, JavaScript may continue to play an important role in Webview. After all, with the continuous development of technologies such as HTML5, Web applications have become a part that cannot be ignored.

In addition to Java and JavaScript, Android development also involves other programming languages, such as C, C, etc. Different programming languages ​​have their own advantages and disadvantages. Which programming language to choose mainly depends on the application scenario and personal preference. For developers, the most important thing is to master the programming language of choice and continuously improve themselves through continuous practice.

In general, for novices, it is a better choice to start with Java. Because Java is widely used in Android development, problems encountered during the development process are relatively easy to solve. At the same time, Java language tutorials and related literature are also quite abundant, making it easier to get started. For some developers with a foundation in Web development, JavaScript will be a better choice because it can be directly applied to the development of Webview and Web applications.

Both Java and JavaScript have their own charm and application scenarios. With continuous exploration and practice, I believe you will become more and more fond of these two programming languages.
