This is the slide that shared with The Alliance Foundation in Taipei office. The purpose is to let them know more about the current and future of tech education.
This document discusses various techniques for persisting application data in Android, including:
1. SharedPreferences which allow storing key-value pairs that can be shared within an app but not between apps.
2. Saving activity instance state by overriding onSaveInstanceState() which is called when an activity may be destroyed.
3. Preference frameworks for creating settings screens using XML preference hierarchies and listeners for updates.
4. Reading and writing files using openFileInput() and openFileOutput() which are restricted to the app's directory.
5. Including static resource files in the res/raw folder to bundle with the app.
The document provides an overview of the history and evolution of mobile phones, the hardware and software components of Android phones, and how the Android operating system works. It discusses that Android phones consist of radio hardware and a computer, that Android is an open-source operating system developed by Google and the Open Handset Alliance, and that Android applications are built using the Android software development kit and run on the Dalvik virtual machine.

This document discusses basic widgets in Android user interfaces. It describes labels, buttons, edit texts, check boxes, spinners, radio groups, radio buttons, images views and image buttons. Labels are used to display text and are not editable. Buttons allow clicking actions. Edit texts are editable like text boxes. Check boxes represent two-state selections. Spinners display a single child like a drop-down list. Radio groups contain radio buttons where only one can be selected at a time. Images can be displayed using image views and buttons. All widgets extend from views and can set properties for visibility, background, focus and enabled status.
The document provides tutorials for various user interface widgets in Android application development. It includes tutorials for date pickers, time pickers, spinners, buttons, text fields, checkboxes, radio buttons, toggle buttons, and rating bars. Each tutorial section describes how to add the widget to an app layout, populate it with data where applicable, and add click listeners or other logic to handle user interactions with the widget. The tutorials are intended to demonstrate how to correctly implement and use common UI elements in Android apps.
Lecture Slides for Preferences and Menus [Android ]Nehil Jain
The document discusses different techniques for saving simple application data and preferences in Android, including shared preferences and files. It covers creating and retrieving shared preferences, as well as the preference activity framework which allows defining preference screens in XML. The document also discusses menus in Android, including options menus, context menus, and inflating menu resources.
This document provides an overview of the features and components of an Android development course from BestOnlineCoursesCoupon.com. It discusses the Android environment system, architecture, and how Android is built on the Linux kernel. It also describes the Android runtime, libraries, application framework, and applications. Key application components like activities, services, and broadcast receivers are explained. Additional components for constructing Android applications like views, layouts, intents, and fragments are also covered at a high level. The document aims to give users an overview of what an Android development course would entail.
There are three main types of menus in Android: context menus, options menus, and submenus. Context menus appear with a long press on a view and don't support icons. Options menus appear when the device menu button is pressed and support icons. Submenus are used to organize related menu items under a title. It is best to define menus in XML resource files rather than creating them programmatically in code.
O documento discute interfaces gráficas no Android, incluindo TableLayout para layouts em formato de tabela, DatePicker para seleção de datas, Spinner para seleção de itens em lista suspensa, e AlertDialog para caixas de diálogo. Exemplos de código são fornecidos para ilustrar o uso desses widgets. Exercícios propõem o desenvolvimento de uma aplicação de cinema usando esses componentes.

Being Epic: Best Practices for Android DevelopmentReto Meier
This document provides best practices for Android development. It discusses five "deadly sins" to avoid: sloth (being slow and unresponsive), gluttony (using system resources irresponsibly), hostility (fighting users), arrogance (fighting the system), and discrimination. It also discusses five "glorious virtues" to embrace: beauty (design), generosity (sharing), ubiquity (being everywhere), utility (being useful), and epicness (being legendary). It covers topics like performance, wake locks, navigation, preferences, undocumented APIs, screen sizes, analytics, background updates, location services, and more. The overall message is to create high-quality, useful apps that respect users and system resources.

Science lessons are updated through the use of digital measurement tools that plug directly into the laptops. They record and process data through graphing software that can quickly plot data points for students in a variety of ways. Science experiments are conducted more efficiently — in fewer class periods — allowing students to spend less time recording and graphing data, and more time analyzing and thinking critically. Social studies are enhanced by utilizing up-to-the-minute Internet research and communication with students in various cultures around the globe. Language arts involve more creativity as classmate PCs let students develop not only written documents, but also multimedia presentations with graphics and videos. This approach can be especially effective with students who have more visual learning styles. Math lessons become more fun as students tackle problems through game-like software. Multiple choice quizzes and tests can be administered via computer, making assessments more efficient. Additionally, classroom management software enables teachers to monitor, communicate, and collaborate with students, individually or as a group, to keep them focused and engaged in learning.
