Data binding is a process that establishes a connection between an application's UI and its business logic so that when data changes, it is reflected in the UI and vice versa. Android introduced data binding in 2015 to minimize glue code between layouts and logic. The key steps to using data binding are: 1) adding the data binding library, 2) applying binding to layouts, 3) creating data binding objects, and 4) doing the binding in activities/fragments. Data binding supports observable objects to automatically update views when data changes. It allows binding layout properties like visibility and text fields.
This document discusses MVVM and data binding in Android development. It begins with an overview of MVVM theory and the roles of the model, view, and view model. It then covers Android's data binding library for linking UI components to data sources, including features like variable binding, listeners, and view model composition. The document also provides examples of using data binding with RecyclerView and accessing view values directly. It concludes with some links for further reading on MVVM patterns.
Data Binding in Action using MVVM patternFabio Collini
The Data Binding framework was one of Google’s announcements at I/O 2015, it’s a big change in the code organization of an Android app. Some developers are sceptical about this framework but, if used in the “right way”, it’s very powerful and it allows to remove a lot of redundant boilerplate code from activities and fragments.
In this talk we’ll start from the Data Binding basic concepts and then we’ll see how to use it to improve the architecture of a typical Android application applying the Model View ViewModel pattern. Using this pattern you need to write less code to create an app that can be easily tested using JVM and instrumentation tests.
Android Data Binding in action using MVVM pattern - droidconUKFabio Collini
The document discusses Android Data Binding and the Model-View-ViewModel (MVVM) pattern. It covers the basics of data binding, using custom attributes with data binding, creating reusable UI components with data binding, implementing two-way data binding, and using data binding with RxJava and the MVVM pattern. The speaker presents code examples for setting up data binding in layout XML files and Java code, and binding data to views while ensuring automatic updates when the data changes.
This document discusses data binding in Android using the Android Data Binding Library. It provides an overview of data binding, which establishes a connection between application UI and business logic. It then discusses how the Android Data Binding Library works, including using observable objects to notify when data changes. It demonstrates how to set up data binding in an Android project using XML layouts and Java code. It also covers some advanced features like importing classes and methods into XML, handling click events, and surviving screen orientation changes with data binding. Finally, it discusses how data binding is well-suited for the MVVM pattern and concludes with some links for further information.
MVVM + Data Binding is an architectural pattern that decouples the business logic from the user interface. It involves three layers: the Model layer contains the data, the View layer displays the UI, and the ViewModel layer contains the presentation logic and state. Using MVVM makes the code more testable and follows SOLID principles. The traditional way of having a single activity handle all responsibilities can be difficult to test due to high coupling, but with MVVM the Model and ViewModel layers can be tested independently of Android APIs.
The document discusses using dependency injection (DI) with Vaadin applications. It explains that DI allows defining abstractions and implementations as beans that can then be injected where needed. This loosens coupling and enables features like scopes. The event bus is presented as an example DI extension. Tips are provided like automatically setting up menus based on view bean annotations and internationalization support. Overall DI is said to decouple code and ensure best practices.
Vaadin DevDay 2017 - Data Binding in Vaadin 8Peter Lehto
The document discusses improving editing of customer records in Vaadin 7 applications. It outlines issues with directly using setters and listeners on each field, such as lots of code, implicit saving, and difficulty validating values. It recommends using a FieldGroup to bind fields to properties, which avoids explicit setters, allows committing or discarding changes, and integrates validation into the commit process. However, it notes there may still be room for improvement over the Vaadin 7 approach.

Building modular monoliths that could scale to microservices (only if they ne...David Gómez García
It’s easy these days to fall into the trap of starting to design your whole application with a microservices architecture…. Because, you know, that’s what everyone is doing. Aren't they?
But, are we considering the microservices architecture as a goal or as a means to a purpose?
In this talk, we will go back to the basics and see how DDD, CQRS and EventSourcing practices drive our application design and evolution so that we will start with a monolith. Still, we will have the ability to scale into microservices more or less easily when (and more importantly: if) we need to.

Doze mode is just around the corner. Introduced in Marshmallow, as the shy guy that was allowed to step in only when your device went to sleep. ZzzZzzzz With the new N release, Doze mode becomes the rockstar. He rushes into the room with a big shabang by shooting all background services and network requests that forgot to get away. He should no longer be shy. He just shoots and dances on bones of your scheduled alarms, while you wonder why this particular task is no longer running. With the new Doze mode, you require to adapt your app architecture to the new reality. On this talk, we will learn how to survive Doze mode using Job Scheduler and stay in one piece.
The document discusses best practices for managing memory in Android applications to avoid memory leaks and performance issues. It provides 3 key points:
1. Be aware of how memory is managed in Android and the garbage collection process. Allocations during critical parts like onDraw can cause stutters.
2. Learn techniques to detect memory issues like using LeakCanary, tracking allocations, and dumping the heap. Understanding memory profiles of an app is important.
3. Apply best practices like avoiding long-lived references to activities, using WeakReferences for inner classes, and cleaning up resources on stop to prevent leaks and improve performance. Memory management is important for smooth experiences.
This document discusses using Inter-Process Communication (IPC) mechanisms like Intent, Messenger, and Android Interface Definition Language (AIDL) to allow processes to communicate with each other in an Android app. It provides code examples of implementing IPC using each mechanism to allow a Service to communicate long-running tasks back to an Activity. AIDL is presented as the preferred solution as it allows for synchronous calls, treats the communication in an object-oriented way, and is transparent to the business logic.
This document discusses using Inter-Process Communication (IPC) mechanisms like Intent, Messenger, and Android Interface Definition Language (AIDL) to allow processes to communicate with each other in an Android app. It provides code examples of implementing IPC using each mechanism to allow a Service running in a separate process to communicate tasks and results back to an Activity. AIDL is presented as the most robust solution, allowing synchronous and asynchronous remote calls between processes through generated Java interface stubs.

5. What is Data Binding?
Model View ViewModel (MVVM)
Ongoing link between an element in the user interface
and a value
When a variable’s value is updated, the display on the
user’s screen changes automatically
6. Dependencies
It's a support library - Android 2.1 (API level
7+)
Gradle 1.3.0-beta4 or higher is required
Beta release
18. Observable
Observable Objects
listen for changes of all properties on that object
ObservableFields
listen for changes of a field of that object
Observable Collections
listen for changes on dynamic structures to hold data
28. Why MVP?
- Decoupled layers
- Easy to debug
- Fully testable business logic, data model
29. MVP vs DataBinding
Presenter react on what happen in the view,
retrieves data, formats and display back in the
view
Data Binding will take over the main
responsibilities of the presenter (react and
display). Rest - will go to the enhanced Model -
ViewModel
The presenter acts upon the model and the view. It retrieves data from repositories (the model), and formats it for display in the view.
The thing is that Data Binding framework will take over the main responsibilities of the Presenter (“acting upon the model and the view”), while the remainder is left to the enhanced Model – the ViewModel (“retreiving data from repositories and formatting”).
The ViewModel is a standard Java class whose sole responsibility is to represent the data behind a single View. It can merge data from multiple sources (Models) and prepare that data for presentation.
All the binding and updating of data to the view is done through the Data Binding Framework. The ObservableField class allow the View to react on changes to the model, and the XML references to fields allow the framework to push changes back to the ViewModel when the user acts upon the View. You can also programmatically subscribe to changes in fields.
One great advantage of representing the visual state of the View in a standard Java class like this is clear: You can easily unit test the visual behaviour.
