在library中设置buildConfigField无用

描述的现象：

设置buildConfigField的IS_PUBLIC无用 一个app，两个module，一个是application module，另外一个是library module； 在library中设置buildConfigField，如下

release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' buildConfigField("boolean", "IS_PUBLIC", "true") } debug{ buildConfigField("boolean", "IS_PUBLIC", "false") }

用来控制http及debug在测试环境，和正式环境的不同； 然而，无论如何都只能得到IS_PUBLIC为false；

最后子stackoverflow上得到了解决 http://stackoverflow.com/questions/20176284/buildconfig-debug-always-false-when-building-library-projects-with-gradle

解决方法如下

With Android Studio 1.1 and having also the gradle version at 1.1 it is possible:

Library

android { publishNonDefault true }

App

dependencies { releaseCompile project(path: ':library', configuration: 'release') debugCompile project(path: ':library', configuration: 'debug') }

亲测好用！
