Are you willing to modernize the Android application built on Java using Kotlin and common Android architecture patterns as well as enhance your applications by overcoming common performance issues with Android? Then this course is for you! As this course assumes basic android development knowledge, you will get started with learning to create a strong architectural background for your app, edit and customize the foundations of the app & much more. Then, youll learn to implement Life Cycle Aware Components, use the ViewModel LiveData framework, and perform data management and persistence with the Room persistence solution. Moving further you will delve into fixing issues such as memory management, where we will look at memory leaks and tracking allocations as well as look at optimizing your user experience when working with data on the cloud. By the end of the course, youll be able to build real-world applications more efficiently, modernize your Android apps using all the new features & deploy applications more efficiently, without having to worry about your code affecting the performance and user experience. Contents and OverviewThis training program includes 3 complete courses, carefully chosen to give you the most comprehensive training possible. The first course, Building Professional Android Applications well create a strong architectural background for your app. Youll be able to edit and customize the foundations of the app so its transferable between different projects. Then, youll learn the most productive ways to save and read data on Android with the Room framework, ObjectBox, and the Firebase database. The third section is about utilizing efficient data structures to maintain speed, even when the amount of data is huge. Finally, well explore different ways to test Android applications such as: unit tests, integration tests, and end-to-end tests. The last section is about designing the front end of your app, including professional-level features, such as custom view development and explanatory user onboarding. Also, youll learn to upload your Android app to the Google Play store and discover advanced topics such as Payments, Android N Tiles, and voice interaction. By the end of the course, youll have the essential skills needed to build a real-world application. The second course, Modernizing Your Android Applications youll take an existing Android application build in Java and modernize it using the Kotlin language, seeing the importance of planning the architecture using SOLID principles and common Android Architecture using the MVP, MVC, and MVVM patterns. Moving on, youll implement Life Cycle Aware Components, use the ViewModel LiveData framework, and perform data management and persistence with the Room persistence solution. Youll see how Kotlin efficiently accelerates the development by improving the code base. With the advanced Architectural Components, youll not only be able to improve the performance but also enhance the UI of your application to a whole new level. By the end of this course, youll have modernized your Android app using all the new features from coding it in Kotlin to implementing Architecture Components to enhancing the UI of your app, which gives you more control on your app and makes it easy to maintain. The third course, Troubleshooting Android Performance will help you overcome common performance issues on Android. In this course, we go over the important and common areas that can affect performance such as memory, network, UI, and battery. We delve into issues such as memory management, where we will look at memory leaks and tracking allocations. We also look at optimizing your user experience when working with data on the cloud. We also go into some common pitfalls when working with your UI and how to debug it. Finally, we look at ways to optimize and debug your app’s battery usage to ensure that it doesn’t annoy users when they’ve installed your app. When you’re completed with this course, you will be developing applications more efficiently, without having to worry about your code affecting the performance that your users experience. About the Authors: Tadas ubonis started coding roughly when he was thirteen. Since then, he has programmed with PHP, JavaScript, Python, C++, and Java (the language in which he has probably written the most code). He took up Android in 2014 and identified that Android lacks decent support for asynchronous programming (Async Task was/is a joke) while more reckless languages, such as JavaScript, had Promises for a long time. Furthermore, Java’s standard library was lacking decent support for functional programming primitives (map, filter), but that was easily fixable with libraries such as Guava. This lead Tadas to a search for a library that would help him achieve a Promise-like functionality and interface. It didn’t take long until he found ReactiveX and its family of implementations (including RxJava) that handle streams in Reactive fashion. It wasn’t exactly the flow of Promised-like systems but soon e
