Android應用開發高效工具集1---ant構建簡單Android項目

[linc@localhost BallGame]$ android -h update project


       Usage:
       android [global options] update project [action options]
       Global options:
  -h --help       : Help on a specific command.
  -v --verbose    : Verbose mode, shows errors, warnings and all messages.
     --clear-cache: Clear the SDK Manager repository manifest cache.
  -s --silent     : Silent mode, shows errors only.


                         Action "update project":
  Updates an Android project (must already have an AndroidManifest.xml).
Options:
  -l --library    : Directory of an Android library to add, relative to this
                    project's directory.
  -p --path       : The project's directory. [required]
  -n --name       : Project name.
  -t --target     : Target ID to set for the project.
  -s --subprojects: Also updates any projects in sub-folders, such as test
                    projects.

除了參數-p路徑是必須的，其他參數都可以不帶。但是建議名稱-n要加上，否則會默認以Activity名稱來命名。-t可以不做修改，項目的Target Id其實就是指Android API的版本，我們可以查看項目的project.properties,以此為基准，如下：

[linc@localhost BallGame]$ tail project.properties 

...
# Project target.
target=android-4

[linc@localhost BallGame]$ android update project  -p .
Updated local.properties
No project name specified, using Activity name 'MainActivity'.
If you wish to change it, edit the first line of build.xml.
Added file ./build.xml
Added file ./proguard-project.txt

也可以指定更全的參數：

[linc@localhost BallGame]$ android update project  -p . -n BallGame -t android-4
Updated project.properties
Updated local.properties
Updated file ./build.xml
Updated file ./proguard-project.txt
