Question

在我的

上使用google cloud stt示例应用时出现以下错误

Android studio：应用程序本身已经编译并在另一个

中运行

Android工作室环境。

编译错误

Program type already present:com.google.protobuf.AbstractMessageLite$Builder
$LimitedInputStreamMessage{kind=ERROR, text=Program type already present: 
com.google.protobuf.AbstractMessageLite$Builder$LimitedInputStream, 
sources=[Unknown source file], tool name=Optional.of(D8)}

我的操作系统是ubuntu 16.04，Android版是Android studio V 3.1。下面这是一个gradle源。

的build.gradle（项目）

// Top-level build file where you can add configuration options common 
to all sub-projects/modules.

buildscript {
repositories {
    jcenter()
    google()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.0'
    classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.5'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
repositories {
    jcenter()
    google()
    mavenCentral()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

build.gradle（模块：应用）

apply plugin: 'com.google.protobuf'

   ext {

compile 'com.android.support:multidex:1.0.0'
}

gradle来源

compile "io.grpc:grpc-protobuf-lite:$grpcVersion"

评论此部分不会导致错误。与protobuffer和grpc相关的错误，但很难正确解决。

我需要帮助。

我有同样的问题，可以通过在gradle.properties文件中设置Gradle属性来禁用D8工具来暂时暂时解决：

android.enableD8=false

我正在使用Android Studio 3.2 RC2。

程序类型已存在：com.google.protobuf.AbstractMessageLite $ Builder $ LimitedInputStream
