java - Box2d 不会使用 LibsGDX 和 Gradle 进行加载

Question

我的设置:Android Studio 0.8.1

按照教程操作: https://github.com/libgdx/libgdx/wiki/Dependency-management-with-Gradle

我花了好几天的时间试图让这个工作摆脱困境。

尝试在 Nexus 4 上运行此程序。

我的 gradle 构建文件:

apply plugin: 'android'

android {
compileSdkVersion 19
buildToolsVersion "19.1.0"

defaultConfig {
    minSdkVersion 14
    targetSdkVersion 19
}

buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}
}

configurations { natives }

dependencies {
configurations { natives }

compile "com.badlogicgames.gdx:gdx:1.2.0"
compile "com.badlogicgames.gdx:gdx-backend-android:1.2.0"
natives "com.badlogicgames.gdx:gdx-platform:1.2.0:natives-armeabi"
natives "com.badlogicgames.gdx:gdx-platform:1.2.0:natives-armeabi-v7a"

compile "com.badlogicgames.gdx:gdx-box2d:1.2.0"
}

现在，当我尝试运行该应用程序时，我总是收到错误消息:

Answer 1

我也有同样的问题。这似乎是因为库没有被复制或者在设备上的正确库路径中找不到。

Fwiw，我正在从模拟器运行这个(如果这很重要)，但我真的陷入困境/沮丧
