What is android ?

Android is a software stack for mobile devices that includes an Operating system, middle-ware and key applications. The Android SDK provides the tools and APIs necessary to develop applications on the Android platform using the Java programming language.

The Android operating system (OS) is based on the Linux kernel. Unlike Apple’s iOS, Android is open source, meaning developers can modify and customize the OS for each phone.

Therefore, different Android-based phones often have different graphical user interfaces GUI’s even though they use the same OS.

Android phones typically come with several built-in applications and also support third-party programs. Developers can create programs for Android using the free Android software developer kit (SDK).

We write android programs in Java Programing language and run through a Java virtual machine JVM.  They use “Dalvik” JVM  through Android 4.4 and after replace it by Android Runtime or “ART” in Android 5.0.
