Android Studio 在 APK 中复制文件错误 sdk_logo_1.png

Question

我正在使用 Android Studio 和 Wikitude Sdk Epson 库。当我运行应用程序时，我收到一个运行错误，说我有重复的文件。我查看了来源，似乎找不到任何重复的文件。当我从 libs 文件夹中删除 wikitudesdk 时，我收到一条错误消息，指出它无法解析依赖项，但列出了两个重复的 wikitudesdk.jar 文件。也许我的依赖关系不正确？任何建议将不胜感激！谢谢你。

错误：

错误：任务“:app:transformResourcesWithMergeJavaResForDebug”执行失败。

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK sdk_logo-1.png File1: C:\Users\myusername\AndroidStudioProjects\Test2\app\libs\wikitudesdk.jar File2: C:\Users\myusername\AndroidStudioProjects\Test2\app\libs\wikitudesdk.jar

Build.Gradle 文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "com.example.pmbi002.test2"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile(name: 'wikitudesdk', ext: 'jar')
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.google.android.gms:play-services-appindexing:8.1.0'
}

repositories {
    flatDir{
        dirs 'libs'
    }
}

删除编译后的错误（名称：'wikitudesdk'，分机：'jar'）：

感谢您的建议！他们帮助我确定我确实有一些错误。我通过删除 "compile(name: 'wikitudesdk', ext: 'jar')" 并将 buildToolsVersion“24.0.0”更改为 buildToolsVersion“23.0.3”来解决问题。
