Android 입문 따라하기 : Hello, Android 출력하기#
관련링크 : http://developer.android.com/guide/tutorials/hello-world.html
01. Android Project 생성하기(File -> New -> Project)#
02. Android -> Android Project 선택#
- Project name: HelloAndroid
- Application name: Hello, Android
- Package name: com.example.helloandroid (or your own private namespace)
- Create Activity: HelloAndroid
- Min SDK Version: 4
각 항목별 설명 - 해석은 나중에#
- Project Name // 프로젝트 명칭 - 이클립스에서 나타나는 프로젝트 이름
- This is the Eclipse Project name — the name of the directory that will contain the project files.
- Application Name // 응용프로그램 명칭 - 사용자가 인식할 수 있는 것이며, Android 장치의 이름을 표현
- This is the human-readable title for your application — the name that will appear on the Android device.
- Package Name //
-
This is the package namespace (following the same rules as for packages in the Java programming language) that you want all your source code to reside under. This also sets the package name under which the stub Activity will be generated.
Your package name must be unique across all packages installed on the Android system; for this reason, it's very important to use a standard domain-style package for your applications. The example above uses the "com.example" namespace, which is a namespace reserved for example documentation — when you develop your own applications, you should use a namespace that's appropriate to your organization or entity.
- Create Activity
- This is the name for the class stub that will be generated by the plugin. This will be a subclass of Android's Activity class. An Activity is simply a class that can run and do work. It can create a UI if it chooses, but it doesn't need to. As the checkbox suggests, this is optional, but an Activity is almost always used as the basis for an application.
- Min SDK Version
- This value specifies the minimum API Level required by your application. If the API Level entered here matches the API Level provided by one of the available targets, then that Build Target will be automatically selected (in this case, entering "2" as the API Level will select the Android 1.1 target). With each new version of the Android system image and Android SDK, there have likely been additions or changes made to the APIs. When this occurs, a new API Level is assigned to the system image to regulate which applications are allowed to be run. If an application requires an API Level that is higher than the level supported by the device, then the application will not be installed.
