链接个别本地源文件到Android Studio项目 [英] Link individual native source file to Android Studio project

问题描述

我在找一个单独的源文件链接到一个Android Studio项目。我使用的是全新的Andr​​oid 1.3+工作室与NDK的支持。

I'm looking to link an INDIVIDUAL source file to an Android Studio project. I'm using the new Android Studio 1.3+ with NDK support.

在我模块的build.gradle文件，我可以通过链接整个源文件夹：

In my module's build.gradle file, I'm able to link entire source FOLDERS via:

android{
   sourceSets {
      main.jni.srcDirs += 'C:/users/jforce/native'
   }
}

以上块将添加在本地文件夹中的所有原始的源文件。

The above blocks will add all native source files in the 'native' folder.

不过，我希望增加单个源文件。例如。 JUST位于C文件：/users/jforce/native/test.c，而不会在同一文件夹中添加任何邻国文件

However, I'm looking to add individual source files. eg. JUST a file located at C:/users/jforce/native/test.c, without adding any neighboring files in the same folder.

下面是我到目前为止已经试过：

Here's what I've tried so far:

main.jni.sourceFiles.getFiles() += "C:/users/jforce/native/test.c"

Android的工作室不喜欢这一个。左操作数为红色，并强调值无效分配到显示，当我鼠标。这是令人困惑我，因为在Android /摇篮文档中说，该方法返回一组与通用的参数文件。 sourceSets.main.jni.srcDirs也返回一组与通用的参数文件，我能够合法地使用+ =操作上确定，但不是在这里。

Android Studio does not like this one. The left operand is underlined with red and 'Invalid value to assign to' is displayed when I mouse over. This is confusing to me, because the Android/Gradle documentation says that this method returns a Set with generic param File. sourceSets.main.jni.srcDirs also returns a Set with generic param File, and I'm able to legally use the += operator on that Set, but not here.

https://docs.gradle.org/current/javadoc/org/gradle/api/file/FileCollection.html#getFiles()

好吧，那么我想这一点：

Okay, so then I tried this:

main.jni.sourceFiles.getFiles().add("C:/users/jforce/native/test.c")

这默默的失败。我的项目建立没有错误，但源文件不被添加到我的项目。

This failed silently. My project builds without error, but the source file isn't added to my project.

作为万福玛利亚，我又试图这样的：

As a Hail Mary, I then tried this:

main.jni.sourceFiles.join("C:/users/jforce/native/test.c")

要在最后一次尝试类似，失败默默为好。该文件没有添加。

Similar to the last attempt, this fails silently as well. The file isn't added.

有谁知道如何单独的本地源文件正确链接到一个Android工作室1.3+项目？任何帮助将大大AP preciated。谢谢！

Does anyone know how to properly link an INDIVIDUAL native source file to an Android Studio 1.3+ project? Any help will be greatly appreciated. Thanks!

推荐答案

我想通了这一点。

android{
   sourceSets {
      main.jni.srcDirs += 'C:/users/jforce/native/test.c'
   }
}

作品。在本地文件夹中没有其它文件被添加。非常反直觉的财产暴露来源档案，但我知道了现在的工作！

Works. No other files in the 'native' folder are added. Very counter-intuitive with the sourceFiles property exposed, but I've got it working now!
