我正在尝试按照位于以下位置的 Android Studio 实验性插件用户指南说明进行操作:
http://tools.android.com/tech-docs/new-build-system/gradle-experimental
修改位于以下位置的 Mapbox GL Native 库:
https://github.com/mapbox/mapbox-gl-native
具体来说，我修改了以下Android文件:
https://github.com/mapbox/mapbox-gl-native/blob/master/platform/android/build.gradle
我的目标是修改库以便调试它。理想情况下，我将能够使用 Android Studio 构建库并调试 C/C++ 代码。到目前为止我可以构建它，但我无法调试它。一位在 Mapbox 工作的程序员告诉我他们也不知道如何调试 Android 代码，所以我怀疑这不是一个容易实现的目标。
我做了很多不同的尝试来应用 Android Studio 实验插件用户指南说明，但我没有 Gradle 经验，我最近的尝试给我留下了以下我不理解的错误消息:
Gradle 'android' project refresh failed Error:Cause:org.gradle.api.internal.ExtensibleDynamicObject
有谁知道如何修改这些文件以让它们构建可调试的 Android NDK 库？导致上述错误的原因是什么？
我正在使用:
> Linux Mint 17.2
> Android Studio 2.1.1
> Build #AI-143.2821654, built on April 28, 2016
> JRE: 1.8.0_65-b17 amd64
> JVM: Java HotSpot(TM) 64-Bit Server VM by Oracle Corporation
以下是我目前修改的 4 个文件。因为我是 Gradle 的新手，所以不要假设我已经正确地进行了任何修改。我只是试图应用 Android Studio 实验性插件用户指南说明，直到我成功构建。
谢谢

最佳答案
您的 gradle 方法实质上是将 Android SDK Makefile 重写或移植到 gradle。要解决您在 Linux 上所做的事情，您可能需要修改现有的 Makefile。
原因是 Mapbox Android SDK build process使用 make android 构建目标 libmapbox-gl.so。您拥有的 Gradle 项目包括 .so 文件和您常用的 Java 代码。
make android 调用 mapbox-gl-native/Makefile
并生成 mapbox-gl-native/build/android-arm-v7/Makefile，您可能需要研究如何修改以生成调试信息，正如 Chris Stratton 在上面的评论中提到的.
当您着手修改 C++ 时，您将需要修改 settings.gradle 以将修改后的 .so 用于 Android。
include ':MapboxGLAndroidSDK'
project(':MapboxGLAndroidSDK').projectDir = new File(rootProject.projectDir, '<relative-path-to>/../mapbox-gl-native/platform/android/MapboxGLAndroidSDK')
include ':app'
另一件需要考虑的事情——你能为 Linux 构建一个可调试的版本吗？
我们已经使用 Xcode 调试器为 Mapbox SDK 成功调试了 C++，因为我们还构建了一个 iOS 应用程序。我知道这不符合您的确切需求，但我提到它是为了防止您实验室或组织中的任何其他人可以访问 OS X 上的 Xcode 并可以使用 make iproj 开始调试。
