This article compares the application programming interfaces (APIs) and virtual machines (VMs) of the programming language Java and operating system Android.. While most Android applications are written in Java-like language, there are some differences between the Java API and the Android API, and Android does not run Java bytecode by a traditional Java virtual machine (JVM), but instead by a ...
Google states that [3] "Android apps can be written using Kotlin, Java, and C++ languages" using the Android software development kit (SDK), while using other languages is also possible. All non- Java virtual machine (JVM) languages, such as Go , JavaScript , C , C++ or assembly , need the help of JVM language code, that may be supplied by ...
The Java language is a key pillar in Android, an open source mobile operating system. Although Android, built on the Linux kernel, is written largely in C, the Android SDK uses the Java language as the basis for Android applications but does not use any of its standard GUI, SE, ME or other established Java standards.

Android Studio supports all the same programming languages of IntelliJ (and CLion) e.g. Java, C++, and more with extensions, such as Go; [19] and Android Studio 3.0 or later supports Kotlin, [20] and "Android Studio includes support for using a number of Java 11+ APIs without requiring a minimum API level for your app". [21]
Unlike Java Virtual Machines, which are stack machines, the Dalvik VM uses a register-based architecture that requires fewer, typically more complex, virtual machine instructions. Dalvik programs are written in Java using the Android application programming interface (API), compiled to Java bytecode, and converted to Dalvik instructions as ...
MicroEmulator has official support for the Android platform. [29] It is also possible to convert J2ME MIDlet JAR-packages into standalone APK files. [30] J2ME Loader — is an enhanced fork of MicroEmulator for Android. [31] [32] JL-Mod — is an enhaced fork of J2ME Loader with the Mascot Capsule 3D API support. [33] [34]
Android Inc. was founded in Palo Alto, California, in October 2003 by Andy Rubin and Chris White, with Rich Miner and Nick Sears [13] [14] joining later. Rubin and White started out build an Operating System for digital cameras viz FotoFrame. The company name was changed to Android as Rubin already owned the domain name android.com.
Java support While most Android applications are written in Java, there is a Java virtual machine in the platform and Java byte code is not executed. Java classes are compiled into Dalvik executables and run on using Android Runtime or in Dalvik in older versions, a specialized virtual machine designed specifically for Android and optimized for battery-powered mobile devices with limited ...
