What is Symbian? An proprietary operating system for mobile devices and smartphones by Symbian Ltd. Symbian is the world's most popular mobile operating system, accounting for 50% of smartphone sales in Q The process of publishing the source code under the Eclipse Public License (EPL) was slated for completion in

Symbian’s History YearEvent 1980Psion founded by David Potter 1984Psion Organiser launched 1986the "vastly improved" Psion Organiser II launches, with a simple-to-use database programming language, OPL. 1987Psion begins development of its “SIBO" family of devices and its own new multitasking operating system called EPOC to run its PDA products. 1989First EPOC16 devices, the MC400 and MC200, ship with a primarily 1-bit, keyboard-operated graphical interface. 1997The first version of EPOC32 Release 1 appeared on the Psion Series 5 ROM v1.0. The EPOC32 operating system, at the time simply referred to as EPOC, was later renamed Symbian OS. EPOC32 was a pre-emptive multitasking, single user operating system with memory protection, which encourages the application developer to separate their program into an engine and an interface. 1998In June Psion Software became Symbian, a major joint venture between Psion and phone manufacturers Ericsson, Motorola, and Nokia. As of Release 6, EPOC became known simply as Symbian OS. 1999The Psion Series 5mx, Psion Series 7, Psion Revo, Diamond Mako, Psion netBook, netPad, GeoFox One, and Ericsson MC218 were released using ER5. A phone project was announced at CeBIT, the Phillips Illium/Accent, but did not achieve a commercial release. 2000The first phone, the Ericsson R380 was released using ER5u in November. 2001The first 'open' Symbian OS phone, the Nokia 9210 Communicator, was released in June Bluetooth support was added. Almost 500,000 Symbian phones were shipped in 2001, rising to 2.1 million the following year. 2003First shipment of Symbian OS 7.0 and 7.0s, an important Symbian release which appeared with all contemporary user interfaces including UIQ, Series 80, Series 90, Series 60 as well as several FOMA phones in Japan. It also added EDGE support and IPv6. One million Symbian phones were shipped in Q1 2003, with the rate increasing to one million a month by the end of Psion sells its stake in Symbian millionth phone with Symbian OS is shipped. 2008Symbian acquired by Nokia; Symbian Foundation formed. 7

What is Android Android is a software stack for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language. 12

Android’s History In July 2005, Google acquired Android, Inc. Update History: –1.5 (Cupcake) Released on 30 April 2009 –1.6 (Donut) Released on 15 September 2009 –2.0 (Eclair) Released on 26 October 2009 –2.0.1 Release 1 Released on 3 December 2009 –Upcoming software stack is to be named Flan 13

Android’s History Handset layouts The platform is adaptable to larger, VGA, 2D graphics library, 3D graphics library based on OpenGL ES 1.0 specifications, and traditional smartphone layouts. StorageThe Database Software SQLite is used for data storage purposes ConnectivityAndroid supports connectivity technologies including GSM/EDGE, CDMA, EV-DO, UMTS, Bluetooth, and Wi-Fi. MessagingSMS and MMS are available forms of messaging including threaded text messaging.text Web browserThe web browser available in Android is based on the open-source WebKit application framework. The browser scores a 93/100 on the Acid3 Test. Java supportSoftware written in Java can be compiled to be executed in the Dalvik virtual machine, which is a specialized VM implementation designed for mobile device use, although not technically a standard Java Virtual Machine. Media supportAndroid supports the following audio/video/still media formats: H.263, H.264 (in 3GP or MP4 container), MPEG-4 SP, AMR, AMR-WB (in 3GP container), AAC,HE-AAC (in MP4 or 3GP container), MP3, MIDI, OGG Vorbis, WAV, JPEG, PNG, GIF, BMP. Additional hardware suuport Android can use video/still cameras, touchscreens, GPS, accelerometers, magnetometers, accelerated 2D bit blits (with hardware orientation, scaling, pixel format conversion) and accelerated 3D graphics. Development environment Includes a device emulator, tools for debugging, memory and performance profiling, a plugin for the Eclipse IDE. MarketLike many phone-based application stores, the Android Market is a catalog of applications that can be downloaded and installed to target hardware over-the-air, without the use of a PC. Originally only freeware applications were supported. Paid-for apps have been available on the Android Market in the United States since 19 February [36] The Android Market has been expanding rapidly. By December, 2009, it had over 20,000 Android applications for download. [36] Muti-touchAndroid has native support for multi-touch which is available in newer handsets such as the HTC Hero. The feature was initially disabled at the kernel level (possibly to avoid infringing Apple patents on touch-screen technology) 14

Android’s Features Application framework enabling reuse and replacement of components Dalvik virtual machine optimized for mobile devices Integrated browser based on the open source WebKit engine Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification SQLite for structured data storage Media support for common audio, video, and still image formats GSM Telephony Bluetooth, EDGE, 3G, and WiFi Camera, GPS, compass, and accelerometer Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE 15

Activity AP 中每一個頁面都是一個 Activity ， AP 是由多 個 Activity 所構成。 Activity 之間可以相互跳轉 Activity 有其生命周期，是由 Android 系統負責 管理生命周期 可以在 Activity 中添加 UI 元件並由 View 決定佈局 方式 85

Activity with View & Widget List Checkbox Button Grid 86

Service Service 為一個背景程式，沒有 UI 介面， 可以應用在音樂播放程式中，實現一邊 上網一邊聽音樂的功能 當 Activity 被其他 Activity 覆蓋後，可以 將欲持續執行的工作轉交給 Service Service 也有生命週期生命週期 87

Activity with Intent Intent 是用來描述一個 AP 可以做的工作 有哪些 IntentFilter 是用來描述該 activity / service 能夠做的工作有哪些 88

Broadcast Receivers 使 AP 能對外部事件進行處理 89

Content Provider 在 Android 系統中每一個 AP 的數據都是私有的 ，必須透過 Content Provider 實現 AP 之間的數 據交換工作 例如某一個 AP 可以去存取通訊錄 AP 建立的聯 絡人資料。 90
