Unity Android && Ant Automate Build 之一
这几天抽空研究下Android SDK 自动化打包。顺便温习下Unity 与 Android 交互机制。
一、Unity 与 Android 的 消息传递机制
Example:
导出 Android Project
这里为了测试，就填了包名能导出就行了
Eclipse 导入之后 在 最开始启动的Activity 上加上一个被 u3d 代码调用的函数 即可
1 public void BeCalledFromUnity(String arg) 2 { 3 UnityPlayer.UnitySendMessage("SDK", "BeCalledFromAndroid", arg); 4 }
OK
消息通信搞定了
二、配置 Ant 环境
Step:
Download Ant. Uncompress the downloaded file into a directory.
Set environmental variables JAVA_HOME to your Java environment,
ANT_HOME to the directory you uncompressed Ant to, and add${ANT_HOME}/bin (Unix) or %ANT_HOME%/bin (Windows) to your PATH.
Check Installation:
You can check the basic installation with opening a new shell and typing ant. You should get a message like this
Buildfile: build.xml does not exist!
Build failed
So Ant works. This message is there because you need to write an individual buildfile for your project. With a ant -versionyou should get an output like
Apache Ant(TM) version 1.9.2 compiled on July 8 2013
三、With Android Project
参考：http://www.androidengineer.com/2010/06/using-ant-to-automate-building-android.html (目前我用的是1.9.4 有一点出入)
If you already have a project that you'd like to add the Ant build script to, then there is an easy command line tool you can use.
Open up a command prompt and navigate to the base directory of your project.
From there, use the command:
android update project --path .
(PS:
Add Path If Fail
%ANDROID_SDK%\platform-tools
%ANDROID_SDK%\tools
)
Here is an example of successful output:
其中ant.properties 是 手工添加的,为了自动化打包签名
Open up a command prompt and navigate to the base directory of your project.
From there, use the command:
-> ant release
=> 打包成功
目前我们已经构建了发布版本的签名APK，下一篇我会讲讲自定义build.xml 流程
