Access build.xml properties from Java

Question

I have an Android application that is by default built with Ant.

There is build.xml file which loads local.proerties file. I would like to add my custom property (for example Google Maps apiKey) and access it in Java classes - for example in some MainActivity.

How can I achieve it ?

Answer 1

Ant provides a target called "sysproperty". Its like a property tag, but it sets the java System.property. So, you can do something like:

<sysproperty name="foo" value="$THE_EXTRA_PROPERTY">

where "THE_EXTRA_PROPERTY" is the extra property that you added to the properties file that gets loaded.

Answer 2

使用带有过滤器集的替换任务或复制任务，使您的蚂蚁脚本修改包含API密钥的Java源文件或与应用程序捆绑在一起的属性文件。
