Are you an Android developer with some experience under your belt? Are you wondering how the experts create efficient and good-looking apps? Then your wait will end with this video! We will teach you about different Android development patterns that will enable you to write clean code and make your app stand out from the crowd.
The video starts by introducing the Android development environment and exploring the support libraries. You will gradually explore the different design and layout patterns and get to know the best practices of how to use them together. You’ll then develop an application that will help you grasp activities, services, and broadcasts and their roles in Android development.
Moving on, you will add user-detecting classes and APIs such as gesture detection touch screen listeners and sensors to your app. You will also learn to adapt your app to run on tablets and other devices and platforms, including Android Wear, auto, and TV. Finally, you will see how to connect your app to social media.

The prototype makes copies from an original, vastly reducing the number of sub-classes required and any lengthy creation processes.
The decorator allows us to add functionality and properties to an object during runtime without having to make any changes to the original class structure.
The builder Pattern is purpose-built for combining simple objects to form one complex object, and this forms a perfect analogy of making a sandwich.
One of the best ways to add further functionality is with decorator Patterns.
Composite Pattern works in such a way that the client can add individual objects or groups of objects without having to concern itself with which it is dealing with.
This video teaches us to employ a Pattern that does not care what type of component it is dealing with.
If you have a lot of data and access to a web server, it is often best to cache data from this source, as this will both save battery and speed up the application.
In this video, we will get on with storing user preferences using the built-in SharedPreferences interface.
The observer acts like a sentry, keeping watch for a particular event or a state change in its subject or subjects, and then reporting this information to interested parties.
Notifications should only contain pertinent and time-related information. The rule of thumb is only issue a notification if the information cannot wait until the next time the user logs in.
Services do not require a UI, but in other respects, they are similar to activities and have a similar life cycle with associated callback methods that we can use to intercept key events.
The template Pattern is nothing more than a generalization in the form of an abstract class with at least one concrete realization.
The visitor Pattern is designed so that a client can apply a process to a collection of unrelated objects, without having to worry about their differences.
Very sophisticated algorithms can be realized with properly configured finite state machines.
There is still a large area of overlap, particularly concerning games, where many apps can be easily converted to work on TV.
All Android Wear applications act as a companion app and work in conjunction with a main module that runs on the user's handset.
Android Auto can run many apps designed originally for mobile devices.
Including a single web page in an activity or fragment using the WebView class is almost as simple as adding any other kind of view.
Not only is Facebook one of the largest social networks, it is also very nicely set up to assist those wishing to promote their products. The ways that this can work varies from providing automatic logins, customizable advertising, and the ability for users to share products they like with others.
Having a large number of likes is a great way to drive traffic your way, but there is an economy of scale at work here that favors apps with very large numbers of downloads.
