In this Android Introduction, you will learn about the basics of android and its usage and how it can be learned easily. After completing this tutorial you will find yourself at a moderate level of expertise in Android programming from where you can take yourself to next levels.
Android is a Linux based operating system. Android was developed by the Open Handset Alliance, led by Google, and other companies. Basically, it is designed for touchscreen mobile devices such as smartphones and tablet computers.
Android can be programmed in C/C++ but most app development is done in Java (Java access to C Libraries via JNI (Java Native Interface) but nowadays new language has been introduced called Kotlin. One of the most widely used mobile OS these days is android.
The android is a powerful operating system and it supports a large number of applications in Smartphones. Best of all it supports Bluetooth, Wi-Fi, 3G, and 4G networking.

The Android development supports with the full java programming language. Even other packages that are API and JSE are not supported. Android Application Development can be done through these modules which are SDK, EMULATOR, ANDROID DEVICE.
But wait, what if you’ve just begun your career as an Android Developer?
Now here comes the climax, according to Professional Android Developers, if you’ve just started your career as an Android developer or planning to learn Android app development, follow these steps must:
Teach yourself Java
(If you know Java then it would be good for you to understand what the Java code is doing without you plugging the code into the Java to Kotlin Converter.
So teach yourself Java first (if you are new to Android development) before jumping into Kotlin straight away.)
Make sure you understand the concepts very well.
