The document discusses updates to Google Play Services including new features for Cast SDK, Remote Display API, Play Games Analytics, Lite Mode, Google Place API for Android, and sensors. It also lists several Google developer APIs and provides links to their documentation pages.
The document discusses new features and tools for Android development including updates to the Android development IDE, top requested developer features like the Design Support library and vector images, and new annotations in Android M like WorkerThread, Size, and FloatRange. It provides links to additional resources on the "What's New in Android Development Tools" video, Data Binding guide, Android M developer preview blog post, and Android M developer preview website.
The document discusses ListViews in Android, including introducing AdapterViews and common adapter types like ArrayAdapter. It covers implementing a basic ListView with an ArrayAdapter, using custom adapters, view holders for optimization, adding listeners, headers/footers, and using ListActivity for simplified list handling.
The document provides instructions for creating a custom list view in Android. It explains that a list view displays data items and uses an adapter to link the data to views. It demonstrates how to create a custom adapter class that extends BaseAdapter and overrides methods like getCount(), getItem(), and getView(). The getView() method is used to inflate a custom row layout and populate it with data for each list item. The document also shows how to set up the list view in an activity's layout, populate it with sample data, and assign the custom adapter.
Android 13 is now in Beta 3 with new features like predictive back gesture, photo picker, per-app language preferences, and improved copy and paste. It also includes changes like new notification permission rules and foreground service task manager. Android Studio Chipmunk is now stable with enhancements to Compose, jank detection, and Jetifier checks. The Android Jetpack suite was updated with new versions of libraries like Room, Paging, and Navigation. The Android Privacy Sandbox continues work on privacy-preserving APIs.

The document discusses the basic components of drawing in Android - Bitmap, Canvas, Drawing Primitives, and Paint. It provides examples of how to use the Canvas class to draw different primitives like points, lines, rectangles, arcs, and paths using a Paint object. It also demonstrates how to draw text, bitmaps and configure properties of the Paint like color, stroke and style.
Android P includes several new features such as WiFi round-trip-time positioning, display cutout support, the ImageDecoder class for image decoding, and a unified biometric authentication API. It also improves existing features like notifications with enhanced messaging styles, and includes privacy and power management changes such as placing restrictions on background access to sensors and limiting apps' resource usage based on usage patterns.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document discusses Android architecture components. It describes key components like Lifecycles, LiveData, ViewModel, Room, Navigation, Paging, ViewModel SavedState, and Data Binding. It also discusses using architecture components with the MVVM pattern and clean architecture, including layers for the data, presentation and domain. It provides examples of implementing use cases and repositories, and testing use cases. It emphasizes benefits like testable and collaborative code and outlines best practices like proof of concepts for new learning.
Bitmap make our app more beautiful and there are some risk as well if we do not handle it correctly. There are many things about the bitmap that we have to know to understand how it works.
The document discusses Android Architecture Components (AAC) including Lifecycles, LiveData, ViewModel, and Room. It provides an example of building a timer application using these components. A TimerListener observes the Android lifecycle and manages a countdown timer. A TimerLiveData observes the timer and notifies observers of changes. A TimerViewModel exposes the timer data and methods to start/stop it. An Activity observes the TimerLiveData to update the UI and handle timer events.
The document summarizes the new features in Android Studio 3.2 beta, including AndroidX for reorganizing Android support library packages, dynamic delivery of APKs using app bundles, and dynamic delivery of features using dynamic feature modules. It provides details on migrating to AndroidX, building app bundles and dynamic feature modules, and how they allow serving optimized APKs based on user device configuration. The release also includes improvements to the build tools, emulator, and other developer tools.
This document provides an overview of Android Architecture Components and Repository pattern. It discusses the key classes in Architecture Components like Activity/Fragment, ViewModel, Repository, and Data Source. It also summarizes the latest release notes for Lifecycle, Room, and Paging libraries. Additionally, it covers the purpose of the Repository pattern in handling data operations and mediating between different data sources. Finally, it lists some common classes used in a Repository like ApiResponse, Resource, and NetworkBoundResource.
