This article mainly introduces how to use Ant to compile Android project, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

One, prepare ant

Ant official website is available for download

Http://ant.apache.org/

Ant environment configuration:

one. Extract the ant package to the local directory.

two. Set ANT_HOME in the environment variable and set the value to your installation directory.

three. Add ANT_HOME/bin to the path of your system environment.

For more introductions, you can go to google. I believe there are many.

Second, detailed steps and instructions, here we need to know some Android commands.

The prerequisite is that the android sdk environment is configured, so you can execute the android command in any directory, otherwise you have to change to the android-sdk\ tools directory.

I've already configured it here, so no matter what path I'm in,

1. Create an android project

Parameter description:

-k /-- package is the namespace (package name)-a /-- name project name

-p /-- path project-t is the version number of the target platform

C:\ Documents and Settings\ Administrator > android create project-k com.android.Ta nk-a Tank-t 4-p F:\ tank

List the corresponding id numbers android.bat list targets / android list for different versions of the platform

C:\ Documents and Settings\ Administrator > android.bat list targets

For existing android projects, we can go to update (modify the version of the platform), which will automatically add ant configuration files such as build.xml

C:\ Documents and Settings\ Administrator > android update project-- name Tank-t 11-p F:\ tank

Compile: there is no file output for direct ant, so be sure to bring parameters later.

The ant parameters are as follows:

Debug: build release with trial signature: build an application, and the generated apk must be signed before it can be released

Install: install debug-built packages to running simulators or devices

Reinstall

Uninstall

Start the compilation:

E:\ MyLiB\ Android\ AndroidAnt\ MyBoardCastReciver > ant debug

Buildfile: e:\ MyLiB\ Android\ AndroidAnt\ MyBoardCastReciver\ build.xml
