我想从命令提示符创建 .apk 文件。为此我遵循这个链接 http://developer.android.com/guide/developing/building/building-cmdline.html
并尝试用 ant 完成它..但它给了我错误。
任务定义类
com.android.ant.setuptask 不能

任何人都可以帮助我解决我犯的错误，或者为我提供一步一步的教程。
提前致谢...
您需要将 sdk.dir 传递给 ant，即ant -Dsdk.dir=<path to Android SDK>
您还需要指定七个左右的 Android 构建目标之一，因为默认构建目标是“help”。
如果你只是跑ant -Dsdk.dir=<path to Android SDK>，你会得到一些帮助输出，如下所示：
help:
[echo] Android Ant Build. Available targets:
[echo] help: Displays this help.
[echo] clean: Removes output files created by other targets.
[echo] compile: Compiles project's .java files into .class files.
[echo] debug: Builds the application and signs it with a debug key.
[echo] release: Builds the application. The generated apk file must be
[echo] signed before it is published.
[echo] install: Installs/reinstalls the debug package onto a running
[echo] emulator or device.
[echo] If the application was previously installed, the
[echo] signatures must match.
[echo] uninstall: Uninstalls the application from a running emulator or
[echo] device.
BUILD SUCCESSFUL
Total time: 7 seconds
要构建 APK，您必须指定debug or release.
ant -Dsdk.dir=<path to Android SDK> debug
