Hello, Worldاندروید پروژه اولین ایجاد
Creating a New ProjectFile→New→Project→Android Application Project
Creating a New Project• In Eclipse choose,– File→New→Project→Android Application Project
• Application Name:– The name of your application
• Project Name:– Eclipse organizes everything into projects– project name should be one word and CamelCase
• Package Name:– In Java, all source code is organized into packages– Your package name (reverse of your domain name)
Creating a New Project• Minimum required SDK:– minimum version of Android that is required for the
device to run this application• Target SDK:– tells the build tools which version of the Android
platform you are building for• Compile with:– Typically the most recent version that support all API
• Theme:– Base theme to user for application
Configure ProjectNew Android application→Next
Configure New Project
• Create custom launcher icon:– Check to use a simple icon creator
• Create activity:– Check to use activity creator tool
• Mark this project as library:– Check if you want to create a library project to use
in other projects
Android Project Partsاندروید پروژه یک بخشهای
Android Project Important Parts
• Manifest File• Layout XML Code• Strings• The R File• Java Source Code
Manifest File
• Glues everything together• Explains what the application consists of• What all its main building blocks are• What permissions it requires• What is the application name, application icon• What is package name, version Code & Name• …
Layout XML CodeXML file specifies the layout of your screen
Layout XML Code
• XML file specifies the layout of your screen– TextView– Spinner– Button– ImageView
StringsXML file that contains all the text that your application uses
Strings
• XML file that contains all the text that your application uses:– names of buttons– labels– default text– and similar types of strings…
The R FileGlue between the world of Java and the world of resources
The R File
• Glue between the world of Java and the world of resources
• Automatically generated file, and you never modify it
• Recreated every time you change anything in the res directory
Java Source CodeIs what drives everything
Java Source Code
• Is what drives everything• Code that ultimately gets converted to a Dalvik
executable
The Emulatorاندروید مجازی ماشین
The Emulator
• Is an actual code emulator• It runs the same code base as the actual device• Have to create an Android Virtual Device
(AVD), To use the emulator
Emulator vs. Simulator
• sound very similar, but are fundamentally different
• To emulate means to imitate the machine executing the binary code
• An emulator is sort of like a virtual machine• A simulator merely simulates the behavior of
the code at a higher level
Android Virtual Device (AVD)
Android Virtual Device (AVD)
• Start the tool called Android SDK and AVD Manager with in SDK folder
• Choose “New…”• In Create New AVD dialog window, you must
specify some parameters for your new AVD
Android Virtual Device (AVD)
New AVD Dialog• Name:
– can be any name you choose• Device:
– Device that emulator look like• Target:
– designates which version of Android– based on platforms and add-ons downloaded and installed
• Keyboard• Skin• Front Camera• Ram, Internal Storage, SD Card
