Question

我收到此错误

错误：xpp3定义了与Android现在提供的类冲突的类。解决方案包括查找没有相同问题的较新版本或替代库（例如，对于httpclient使用HttpUrlConnection或okhttp替代），或使用jarjar之类的库重新打包该库。 [DuplicatePlatformClasses]

同时生成签名的APK。我怎么解决这个问题。请帮帮我！

App Gradle，

 apply plugin: 'com.android.application'

android {
compileSdkVersion 26
buildToolsVersion '25.0.2'

defaultConfig {
    applicationId "com.casperon.app.rydepass"
    minSdkVersion 17
    targetSdkVersion 26
    versionCode 17
    versionName "4.2"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
aaptOptions {
    cruncherEnabled = false
}

dexOptions {
    javaMaxHeapSize "4g"
}
packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/LICENSE'

Answer 1

尝试一下

   configurations {
    all*.exclude group: 'xpp3', module: 'xpp3'
    compile.exclude group: "org.apache.httpcomponents", module: "httpclient"
}

Answer 2

我有类似的问题。 Apache库已在整个项目中使用，我无法排除该库。今天，我尝试使用jar文件来代替它，并且有效。您可以从此处下载apache http库jar文件： https://jar-download.com/artifacts/org.apache.httpcomponents
