●●●小白求助 关于创建Android应用的问题

[avi___]

本小白初学Android 各位大大见笑 请教点问题

我用命令行创建Android应用 android create project -n HelloWorld -t 7 -p D:\AndroidWorkspaces\HelloWorld -k org.abc.helloworld -a HelloWorld

创建完了以后 我进入D:\AndroidWorkspaces\HelloWorld 这个目录 输入ant.bat 创建了build.xml
之后我想编译该目录下的项目 于是我在该目录下输入ant compile 命令行提示Target "compile" does not exist in the project "HelloWorld"

后来我发现如下提示里没有compile 我的ant安装都没有问题 请求各位大大帮小弟解答一下 感谢

[echo] Android Ant Build. Available targets:
[echo] help: Displays this help.
[echo] clean: Removes output files created by other targets.
[echo] The 'all' target can be used to clean dependencies
[echo] (tested projects and libraries)at the same time
[echo] using: 'ant all clean'
[echo] debug: Builds the application and signs it with a debug key.
[echo] The 'nodeps' target can be used to only build the
[echo] current project and ignore the libraries using:
[echo] 'ant nodeps debug'
[echo] release: Builds the application. The generated apk file must b

[echo] signed before it is published.
[echo] The 'nodeps' target can be used to only build the
[echo] current project and ignore the libraries using:
[echo] 'ant nodeps release'
[echo] instrument:Builds an instrumented package and signs it with a
[echo] debug key.
[echo] test: Runs the tests. Project must be a test project and
[echo] must have been built. Typical usage would be:
[echo] ant [emma] debug install test
[echo] emma: Transiently enables code coverage for subsequent
[echo] targets.
[echo] install: Installs the newly build package. Must either be used
[echo] in conjunction with a build target (debug/release/
[echo] instrument) or with the proper suffix indicating
[echo] which package to install (see below).
[echo] If the application was previously installed, the
[echo] application is reinstalled if the signature matches.
[echo] installd: Installs (only) the debug package.
[echo] installr: Installs (only) the release package.
[echo] installi: Installs (only) the instrumented package.
[echo] installt: Installs (only) the test and tested packages (unless
[echo] nodeps is used as well.
[echo] uninstall: Uninstalls the application from a running emulator or
[echo] device. Also uninstall tested package if applicable
[echo] unless 'nodeps' is used as well.
