标签： android libgdx

我使用LibGDX gradle设置项目，一切正常，直到我将Tween引擎库添加到我们的libGDX项目

我的项目从eclipse转换为android studio。

我的build.gradle看起来像这样：

android {
    buildToolsVersion "21.1.1"
    compileSdkVersion 21
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
        }

        instrumentTest.setRoot('tests')
    }
}
// called every time gradle gets executed, takes the native dependencies of
// the natives configuration, and extracts them to the proper libs/ folders
// so they get packed with the APK.
task copyAndroidNatives() {
    file("libs/armeabi/").mkdirs();
    file("libs/armeabi-v7a/").mkdirs();
    file("libs/x86/").mkdirs();

    configurations.natives.files.each { jar ->
        def outputDir = null
        if (jar.name.endsWith("natives-armeabi-v7a.jar")) outputDir = file("libs/armeabi-v7a")
        if (jar.name.endsWith("natives-armeabi.jar")) outputDir = file("libs/armeabi")
        if (jar.name.endsWith("natives-x86.jar")) outputDir = file("libs/x86")
        if (outputDir != null) {
            copy {
                from zipTree(jar)
                into outputDir
                include "*.so"
            }
        }
    }
}
task run(type: Exec) {
    def path
    def localProperties = project.file("../local.properties")
    if (localProperties.exists()) {
        Properties properties = new Properties()
        localProperties.withInputStream { instr ->
            properties.load(instr)
        }
        def sdkDir = properties.getProperty('sdk.dir')
        if (sdkDir) {
            path = sdkDir
        } else {
            path = "$System.env.ANDROID_HOME"
        }
    } else {
        path = "$System.env.ANDROID_HOME"
    }

    def adb = path + "/platform-tools/adb"
    commandLine "$adb", 'shell', 'am', 'start', '-n', 'com.kilobolt.zombiebird.android/com.kilobolt.zombiebird.android.AndroidLauncher'
}

eclipse {

                    }

            }
        }
    }
}
dependencies {
    compile files('libs/tween-engine-api.jar')
    compile files('libs/tween-engine-api-sources.jar')
}

错误：

import aurelienribon.tweenengine.Tween;// error: package aurelienribon.tweenengine does not exist
import aurelienribon.tweenengine.TweenEquations;//error: package aurelienribon.tweenengine does not exist
import aurelienribon.tweenengine.TweenManager;//error: package aurelienribon.tweenengine does not exist

我真的不知道该怎么做，我无法理解为什么会这样。

对于上下文，此问题似乎引用了LibGDX Zombie Bird Tutorial - Day 11。

按照Universal Tween Engine FileTree Dependency Method说明解决依赖性错误。

说明说：

  

现在应该看看build.gradle文件的项目（＆＃34;：core＆＃34;）部分   像这样：

project(":core") {
   ...

    dependencies {
        ...
        compile fileTree(dir: '../libs', include: '*.jar')
    }
}
  

现在应该在build.gradle文件的项目（＆＃34;：android＆＃34;）部分   看起来像这样：

project(":android") {
   ...

    dependencies {
        ...
        compile fileTree(dir: '../libs', include: '*.jar')
    }
}

按照这些说明操作后，将目录路径修改为＆＃39; ../ libs / tween-engine-api-6.3.3＆＃39;或者您的通用Tween引擎文件夹的名称。请记住将您的项目与刚刚进行的build.gradle更新重新同步。

此项目的完整build.gradle如下所示。但是，我的项目最初是使用LibGDX Setup App生成的，不是从Eclipse导入的。

只需用

替换它 
compile "org.mini2Dx:universal-tween-engine:6.3.3"

在根项目的文件build.gradle中。
