An activity is completely alive when it has state information (saved instance state), maintains member information (variables and objects), and is attached to the Window Manager (can display UI). All three conditions must be met for the activity to be fully functional and interactive.

iOS is Apple's mobile operating system that runs on iPhone, iPad, and iPod Touch devices. OS X (now macOS) is for Mac computers, ARM is a processor architecture, and A4 is a specific mobile processor chip. Apple's mobile OS has been called iOS since its introduction in 2007, replacing the earlier iPhone OS name.

Froyo (short for Frozen Yogurt) was Android version 2.2, which was one of the latest versions around 2010-2011. Google uses dessert-themed codenames alphabetically for Android versions. The other options are made-up names that don't correspond to actual Android versions - Frosting, Froogle (which was a shopping service), and Frappuccino are not Android codenames.

Ovi is Nokia's online service brand (Ovi Store, Ovi Maps, etc.), not a mobile processor. Snapdragon is Qualcomm's processor line, ARM Cortex is a processor architecture family used in mobile devices, and A4 is Apple's custom processor. Ovi was Nokia's ecosystem before they transitioned to Windows Phone and later Microsoft services.

Motorola was the last major entrant to launch an app store, introducing the SHOP4APPS marketplace in 2010. Blackberry had App World since 2009, Apple pioneered with App Store in 2008, and Nokia had Ovi Store in 2009. Motorola was late to the smartphone app ecosystem game, entering just before being acquired by Google in 2012.

Samsung launched the bada OS with the Samsung Wave phone in 2010. Bada was Samsung's proprietary smartphone OS before they fully committed to Android and later developed Tizen. Symbian was Nokia's OS, S60 was a platform on Symbian, and 'vada' is a made-up option. The Wave was the first bada-powered device.

Flash is not a mobile handset vendor - it's Adobe's multimedia platform or a generic term. Micromax, Maxx Mobile, Lemon, and Spice are all Indian mobile phone manufacturers. Flash might refer to Adobe Flash Player (software) or be confused as a brand name, but it's not a handset manufacturer like the others listed.

iOS apps cannot run on macOS because they are compiled for ARM architecture and use iOS-specific frameworks, while Mac apps use Intel binaries and Mac frameworks. Although both are Apple platforms, they have different architectures, SDKs, and app ecosystems. The 250,000+ apps were designed for iPhones and iPads, not Mac computers (this changed years later with Apple Silicon).

HP acquired Palm in July 2010 for approximately $1.2 billion, aiming to use Palm's webOS operating system in tablets and smartphones. Palm was a pioneer in PDAs with their Palm Pilot devices but struggled to compete against iOS and Android. HP eventually discontinued webOS devices in 2011. ZTE, Dell, and Huawei were not the acquirers.

Java has historically been the primary programming language for Android application development, supported by the official Android SDK. While C++ can be used via NDK, it's not the primary development language. Objective-C is used for iOS, not Android. Ruby is not natively supported for Android development.

Research In Motion (RIM), the company behind BlackBerry devices, was founded and headquartered in Waterloo, Ontario, Canada. This is well-established corporate geography knowledge. The UK, US, and France are incorrect locations for RIM's headquarters.

iWidget Package is the deployment format used for WAR files in Mashup Center. It wraps the application in the iWidget specification format required by the platform.

Mashup Builder is the dedicated interface within IBM Mashup Center used to create, design, and modify mashup pages. It provides a visual editor for assembling widgets, configuring layouts, and defining page properties. Data Mashup Builder is used for data transformation tasks, Feed Generator UI is for creating feeds, and Mashup Enabler is a component, not an interface.

The mashup.properties file is a name/value pair configuration file used in IBM Mashup Center to store deployment-specific settings. It contains key properties like contextRoot (the application context path) and componentName (identifying the mashup component). catalog.xml defines catalog entries, widget definition XML files define widget structure, and widget JS files contain widget logic.

In Mashup Center, modifications to a mashup page can be saved by either clicking the 'Save' button explicitly or by navigating away from Edit mode to View mode (via 'Go to View'). Both actions persist your changes. 'Go to Edit' keeps you in edit mode without saving, and 'Switch to a different page' typically prompts to save but isn't a direct save action.

The iw:resource tag in widget definition XML files is used to reference external JavaScript files that implement the widget's functionality. It links the widget's declarative definition to its executable code. iw:content defines widget content structure, iw:reference is for other types of references, and iw:iwidget is the root element of the widget definition.

Published pages are NOT automatically added to the Catalog in IBM Mashup Center. The Catalog is a separate repository where users must explicitly publish or register pages for discovery and reuse by other users. Publishing a page makes it available but doesn't automatically catalog it; manual Catalog entry is a separate action.

The mashup.properties file defines contextRoot (the base URL context path where the mashup application is deployed, like /mashup) and componentName (the unique identifier name for the specific mashup component or application instance). contentName and componentRoot are not standard properties in this file.
