Android runs on many different hardware platforms. There are a large number of developers already proficient in Java. Java has huge open source support, with many libraries and tools available to make developers life easier. Java protects you from many of the problems inherent in native code, like memory leaks, bad pointer usage, etc.

One question we ran across in our research was “Why is Google using Java in Android?”.
Java has a pretty compelling argument for Google using it in Android: it has a huge base of developers. All these developers are (kind of) ready to develop for their mobile platform. Keep in mind that, technically speaking, Android does not use pure Java.
Not sure why exactly Java was chosen but it was probably for a number of reasons To capture the large group of developers who are familiar with and use Java Fill the mobile gap in Java where technologies like J2ME where Java is lacking. Secondly, there is not Java Virtual Machine specified for Android.
Why is Java so popular for mobile app development?
Java is a known language, developers know it and don’t have to learn it it’s harder to shoot yourself with Java than with C/C++ code since it has no pointer arithmetic it runs in a VM, so no need to recompile it for every phone out there and easy to secure several mobile phones already used Java ME, so Java was known in the industry.
Does a Java application run on Android?
If you have gone through Java documentation, you might know that Java application runs on the JVM (Java Virtual Machine), yes that’s correct but not Android. Let’s say we have source code for a calculator application.
What is the difference between Java and Android VMS?
Java itself is usually run on a virtual machine. The JVM itself is a stack machine based VM while Android’s VM (called Dalvik) is a register based VM (this is for the sake of less code generated and faster speed to get better performance out of whatever device is using Android).
The next thing we wondered was: is Android JVM compatible with Java?
Android’s JVM implementation as of version 5.0 and up is known as the Android Runtime (ART). ART is specific to Android and is not historically Java bytecode compatible for reasons that have little to do with engineering and more to do with software licensing.
Does android use jvm?
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 Dalvik virtual machine in older versions of Android, and an Android Runtime (ART).
What is Java Virtual Machine JVM?
Java Virtual Machine (JVM) is a Process virtual machine. Follow “write once, run anywhere” principle, JVM allows programs — written in Java/Kotlin — to run on any device or operating system. Write once, Run anywhere!
