在 Gradle 中为 Android 中的库项目构建变体 [英] Build variants in Gradle for a Library Project in Android

问题描述

我正在尝试使用 Gradle 配置一个包含一些外部库的项目.通过 Gradle，我可以使用 Build Variants 为主应用程序设置不同的环境配置(在配置文件中包含一个类)，以便我可以根据此变量执行代码.

I am trying to configure with Gradle a project which contains some external libraries. With Gradle I can setup different Environmental Configuration (with a class inside a config file) for the main application using the Build Variants so I can execute code according to this variables.

问题是我如何为图书馆项目做同样的事情?我为这个项目创建了这个库，我想为不同的场景设置不同的构建变体.

The problem is that how I can do the same for a library project? I created this library for this project and I would like to setup different Build Variants for different scenarios.

举个例子:在库中，在调试模式下运行时，打印所有日志，以便我在开发时可以看到它们.在发布模式不要.

As an example: In the Library, when running in debug mode, then print all the logs so I can see them while developing. In release mode dont.

文件结构:

src ----- > debug -> java -> config -> PlayerEnvConfig
            main -> com.mypackagename -> etc...
            release -> java -> config -> PlayerEnvConfig

调试中的代码:包配置；

Code in debug: package config;

/**
 * Environment configuration for Release
*/
public final class PlayerEnvConfig {
    public static final boolean USE_REPORTING = true;
    public static final boolean USE_ANALYTICS = true;
    public static final boolean USE_LOGGING = false;
    public static final boolean USE_DEBUG_LOGGING = false;
    public static final boolean USE_DEBUGING = false;
}

发布中的代码:

package config;

/**
 * Environment configuration for Release
*/
public final class PlayerEnvConfig {
    public static final boolean USE_REPORTING = true;
    public static final boolean USE_ANALYTICS = true;
    public static final boolean USE_LOGGING = false;
    public static final boolean USE_DEBUG_LOGGING = false;
    public static final boolean USE_DEBUGING = false;
}

问题是，对于主项目，我可以使用此构建类型为不同场景配置不同的应用程序，但我如何为库项目做同样的事情?

The problem is that for the main project I can use this Build types to configure differently the application for different scenarios, but how can I do the same for the Library Project?

因为目前我在 http://tools.android.com/tech-docs/new-build-system/user-guide 该库只会在测试时使用调试模式.

Because at the moment from what I read in http://tools.android.com/tech-docs/new-build-system/user-guide the library only will use the debug mode while testing.

有什么想法吗?

谢谢！

推荐答案

这是来自 谷歌代码问题，它对我有帮助:

It's a @bifmadei answer from google code issue and it helps for me:

过时:尝试在依赖项目中设置这个

Obsolete: Try setting this in the dependency project

android {
    publishNonDefault true
    ...
}

更新:从 gradle 4.10.1 开始，publishNonDefault 默认为 true.因此，只需使用以下建议:

Update: Starting from gradle 4.10.1 publishNonDefault is true by default. So just use the recommendation below:

在使用它的项目中包含这个

Include this in the project that uses it

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

取自此处:https://code.google.com/p/android/issues/detail?id=66805

新方法:请注意，使用 implementation 指令分隔的 releaseCompile 和 debugCompile 已过时:https://stackoverflow.com/a/44364851/3379437

New approach: Note that with implementation instruction separated releaseCompile and debugCompile become obsolete: https://stackoverflow.com/a/44364851/3379437

但是这种方法仍然可以与自定义构建配置一起使用

But this approach still can be used with a custom build configuration
