What makes Android app development so appealing is that it is based on Java, which is a language pretty much every guy or girl with a computer science degree knows. Secondly, Android being open-source and free to develop with, anyone can start making apps right away without spending a single buck. All you need is an Internet connection and some coding skills. This is a far cry from Apple's model wherein you have to pay Apple to become a developer.
Making apps on Android can be fun, informative, as well as monetarily rewarding. If you are willing to put in some time and effort into learning the basics of Android app development, you will be making good apps very quickly. If your idea is unique enough and the app is relatively bug free, you can release it in the Google Play Store and watch it become popular. You can also monetize it by enabling in-app payments, ads, and even putting a small price for your app.
So, if you are excited about learning how to develop Android apps, read on as we have links to some of the best tutorials out there for getting started.

Android Design Guidelines
This is not a tutorial but a set of principles and guidelines that will help you make your app look like the way it’s meant to be on Android. Many rookie developers -- and some big ones too -- make the mistake of creating apps that look and feel completely out of place. They go in with the thinking that they'll create two apps, one for Android and one for iOS while keeping the design same for both of them. This not only makes the apps you have look weird and clunky, it also shies many customers away from your app. A great way to remedy this problem is study the guidelines first, make a blueprint for the app, and then start creating it.
Learn by Doing - Android for Beginners
This is a great free course with more than seven hours of content that teaches you Android programming in a more practical way. Learn by Doing teaches exactly the way you want it to -- in practical hands-on videos aided by elaborate videos. Accompanying the instructions are exercises to test and hone your skills. Overall, the course is targeted towards helping you get an app running as quickly and as efficiently as possible. If you are looking for something in-depth, make sure you go through Android's official guide, which is quite exhaustive and covers a lot of important concepts. That being said, you'll definitely end up learning a lot of stuff about Android development thus helping you springboard to more complex development topics.
