O Mnie • Nazywam się Andrzej Piotrowski aka Sir Anen • Jestem po Rolnictwie – Kadży orze jak Może • Pracowałem dla Credit Swiss, Viessmann R&D czy IBM’ie + Agencje Kreatwyne – Wrocław • Przeprowadze dla was wstęp techniczny • Czemu nikt mi za to nie płaci • Wiem że Umiem – Ty też to Umiesz (siła woli) • Zaczynamy przygode – pytanie to ręka w górę
- 5. Agenda • Xamarin – Z czym sie to wiąże w Mobile • Android – Jak wygląda praca z Nim • Android Design Patterns – Budujemy z głową i dla ludzi a nie dla własnego dobra (community) • Google Play – Jak to wygląda od strony Dev • Xamarin Android Aplikacja - Przygoda • Zadanie domowe - Rozdzielenie • Ustalenie współpracy ze mną

- 7. Mono? • • “The Mono runtime contains a code execution engine that translates ECMA CIL byte codes into native code and supports a number of processors: ARM, MIPS SPARC, PowerPC, S390 , x86, x86-64 and IA-64 for 64-bit modes.” • • Windows Mono 1.0 was released on June 30, 2004 Runs on Linux, OSX, Windows, PS3, XBox 360, Wii Phone 7 i 8 + Android + iOS

- 26. Android SDK emulator -> <- Genymotion emulator
- 27. Android Application What’s inside an App ? Default Activity Libraries Other Default Default Activities Activity Activity Service Content Android Manifest Drawable Layouts Values Assets
- 30. Edit App Name & Package, Icon, Version #, Min and Target Android SDKs, Permissions
- 32. Pro tip: need for speed You can specify hardware acceleration for the app or for specific activities. http://developer.android.com/guide/topics/graphics/hard ware-accel.html
- 34. Activities
- 36. lifecycle in use
- 37. another example OnResume and OnPause are good places to do assignment and release.
- 38. declaring activity behavior In this case, InitialActivity is our splash/loading screen.
- 39. layouts
- 40. Anatomy of a layout
- 41. includes
- 42. layouts for orientations By creating a directory “layout-land,” Activities will use this as content when orientation changes. http://docs.xamarin.com/guides/android/application_fund amentals/handling_rotation/
- 43. layouts for screen sizes “layout-large” is for Android apps below API-13, “layoutswXXXdp” is for 13 and above.
- 44. How layouts are connected to your code
- 45. Strings.xml
- 46. How to connect strings.xml to your code You can link via layout xml or use “GetString” from your Activity.
- 47. string array This can be used as a data provider for a spinner.
- 48. Style.xml
- 50. Units of measure px Pixels - corresponds to actual pixels on the screen. in Inches - based on the physical size of the screen. mm Millimeters - based on the physical size of the screen. pt Points - 1/72 of an inch based on the physical size of the screen. dp Density-independent Pixels - an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi screen
- 51. Connect style to view
- 52. Drawables
- 53. Using a PNG PNGS FOR STATES
- 54. vector drawable
- 56. alternative drawables Using folder naming conventions will tell Android what version of the drawable to use
- 57. MainApplication
- 58. sending intents
- 60. Create and assign adapter
- 63. Set layout of Activity
- 65. the fragment
- 67. Fragments are important Fragments promote code reuse.
- 68. custom views
- 69. Month Layout
- 70. Week Layout
- 71. notated cell
- 72. OnDraw
- 73. UpdateSwatches
- 75. Update calendar
- 77. when month events set
- 79. Podsumowanie
- 80. - Android SDK w Xamarinie nie jest specialnie trudny ale trzeba mieć background z aplikacjami – dobrze znać ADB. - Ilość urządzeń do przetestowania – o matkoale da się dzięki usługą (TestCloud) czy (TestDroid) - Emulatory są do bani. Testować na urządzeniu bo nakładki. - Planować z głową swoj LayoutUX/Design
- 81. Zadanie Domowe

- Omoiwc android:smallScreensIndicates whether the application supports smaller screen form-factors. A small screen is defined as one with a smaller aspect ratio than the "normal" (traditional HVGA) screen. An application that does not support small screens will not be available for small screen devices from external services (such as Google Play), because there is little the platform can do to make such an application work on a smaller screen. This is "true" by default.android:normalScreensIndicates whether an application supports the "normal" screen form-factors. Traditionally this is an HVGA medium density screen, but WQVGA low density and WVGA high density are also considered to be normal. This attribute is "true" by default.android:largeScreensIndicates whether the application supports larger screen form-factors. A large screen is defined as a screen that is significantly larger than a "normal" handset screen, and thus might require some special care on the application's part to make good use of it, though it may rely on resizing by the system to fill the screen.android:xlargeScreensIndicates whether the application supports extra large screen form-factors. An xlarge screen is defined as a screen that is significantly larger than a "large" screen, such as a tablet (or something larger) and may require special care on the application's part to make good use of it, though it may rely on resizing by the system to fill the screen.
- Beginning in Android 3.0 (API level 11), the Android 2D rendering pipeline supports hardware acceleration, meaning that all drawing operations that are performed on a View's canvas use the GPU. Because of the increased resources required to enable hardware acceleration, your app will consume more RAM.Hardware acceleration is enabled by default if your Target API level is >=14, but can also be explicitly enabled. If your application uses only standard views and Drawables, turning it on globally should not cause any adverse drawing effects. However, because hardware acceleration is not supported for all of the 2D drawing operations, turning it on might affect some of your custom views or drawing calls. Problems usually manifest themselves as invisible elements, exceptions, or wrongly rendered pixels. To remedy this, Android gives you the option to enable or disable hardware acceleration at multiple levels. See Controlling Hardware Acceleration.
- Masa możliwości dla danej aktywności – coś jak properties ale inaczej interpertowane
- Mowa o aktywnościach – co to jest i dlaczego istnieją
- Bardzo ważne !!!!
- Jak się z tego korzysta w Xamarin
- Teraz czas na pytania o coś – powrot do jakiegoś slajdu
