android-studio中基于cocos2dx的项目使用gradle-experimental插件

标签： c++ android-ndk android-gradle cocos2d-x gradle-experimental

我有一个符合gradle实验的0.6.0-alpha1兼容的build.gradle文件：

apply plugin: 'com.android.model.application'

model {
    android {
        compileSdkVersion = 21
        buildToolsVersion = "23.0.2"

        defaultConfig.with {
            applicationId = "com.company.application"
            minSdkVersion.apiLevel = 21
            targetSdkVersion.apiLevel = 21
        }
    }
    android.buildTypes {
        release {
            minifyEnabled = false
            proguardFiles.add(file('proguard-rules.pro'))
        }
    }

    android.ndk {
        moduleName = "moduleName"
    }
}

dependencies {
    compile project(':libcocos2dx')
}

我正在使用cocos2dx作为我的引擎。我有一个文件夹层次结构，如下所示：

  • 类（包含我项目的所有C ++代码）
  • proj.android/src/main/projectName/jni（其中包含要挂钩的cocos2d的main.cpp文件）

我还有许多其他cpp类，它们位于proj.android之外的不同文件夹中（例如cocos2d cpp文件位于proj.android/../../../dependencies/XXXX/cocos2d- x和引擎文件位于proj.android/../../../dependencies/XXXX/engine，我所有的C ++代码都在proj.android/../Classes，就像在每个cocos2dx项目中一样）

我正在尝试使用最新的gradle实验插件（gradle-experimental-0.6.0-alpha1）构建我的应用程序。

我首先尝试按原样构建它，项目编译并运行但是为空（没有生成libMyApp.so），因为我没有在我的gradle构建中包含任何C ++源文件。

然后我创建了一些指向源文件文件夹的符号链接，以便gradle可以选择它们：

ln -s proj.android/../../../dependencies/XXXX/cocos2d-x proj.android/src/main/projectName/jni

现在当我构建（./gradlew assembleDebug）时，我得到它编译符号链接的C ++文件，但无论我尝试什么，它都会在每次第一次包含头文件时失败。

我尝试使用以下内容添加源文件/标头包含here：

android.sources {
        main {
            jni {
                source {
                    srcDir "src"
                }
                exportedHeaders {
                    srcDir "src"
                }
            }
        }
    }

但我无法找到丢失的“.h”标题。如果有人试图使用cocos2Dx，gradle-experimental和android-studio构建一个后续的C ++项目，请随时分享任何经验。我将尝试编译某种指南，当我能够编译它时（有一天:)）

嗨感谢您的文件，我对您的文件进行了一些修改。

我的工作原理是，我在Mac OSX上用cocos2Dx 3.9做到了。

你需要：com.android.tools.build:gradle-experimental:0.6.0-alpha5'

您可以同时在Java和C ++中放置断点。

答案 1 :(得分：0)

所以我最终通过添加

使其工作 
exportedHeaders {
                    srcDir "src"
                }

行并将其指向缺少标题的右侧目录。
