Which Java is used in Android?
Android devices use Java language for application development, but it is not Java Standard Edition (JSE), instead it is Java Micro Edition (JME). The Java ME is also known as Java 2 Platform, Micro Edition (J2ME), and it is used to create application and games specifically designed for small devices such as mobile phones and PDAs.
The Android platform uses a specialized version of the Java language and libraries, but it is still compatible with the syntaxes, features and libraries of standard Java. Therefore, developers familiar with Java language can create applications for Android without the need to learn a new language.
How to set Java 8 in Android Studio?
Setting Java 8 in Android Studio involves several steps that must be completed in order. First, you must ensure your system and the Java Development Kit (JDK) are running on the latest version and that your version of the JDK is version 8.
To check the version of the JDK, open the command line and enter “java –version”. Once you’ve updated your version of the JDK, open Android Studio and navigate to “Settings”, then select “Preferences”.
In Preferences, select “Appearance & Behavior”, then select “System Settings”. Under “System Settings”, select “Android SDK”. In “Android SDK”, select the “SDK Tools” tab and choose “JDK Version”. Set JDK Version to 8 and click OK.
After this, you need to configure the JDK in Android Studio. To do this, navigate back to “Settings”, then select “Build, Execution, Deployment”, then select “Compiler”. In the Compiler menu, select “Java Compiler” and add the “–release” parameter to the end of the existing “Additional command line arguments” setting.
This will force the compiler to use Java 8. Finally, you need to configure the Gradle settings to use Java 8. To do this, open the Gradle settings file and add “sourceCompatibility = 1. 8” to the “android” block.
After you have completed these steps, your Android Studio should be using Java 8.
Can I still use Java 8?
Yes, you can still use Java 8. Java 8 is a popular version of the Java programming language and is the most widely used version today. The current latest version of Java is Java 15, which was released in September 2020.
Java 8 is still suitable for most applications and will continue to receive updates and security fixes through the Java lifetime support policy until at least December 2025. While newer versions of Java do bring additional features and benefits, for many applications developers will not see a compelling benefit in upgrading from Java 8.
There are a lot of libraries and frameworks which are still actively supported and maintained for Java 8, and the language itself remains largely unchanged since it was released. In summary, yes, you can still use Java 8 and there is no immediately compelling reason to upgrade.
Should I install Java 8 or 11?
