昨天，我的应用运行良好。

今天不知道为什么，我重新打开Android Studio后应用程序没有编译了。

显示的错误是

Program type already present: com.google.android.gms.internal.measurement.zzwp
Message{kind=ERROR, text=Program type already present: com.google.android.gms.internal.measurement.zzwp, sources=[Unknown source file], tool name=Optional.of(D8)}

我真的不知道发生了什么，我已经搜索了所有内容，但没有任何效果。 如果有人可以帮助我，我将不胜感激。 我更改了所有依赖项和库以尝试解决它，但没有任何效果。

这里是 build.gradle 项目

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'
        classpath 'com.google.gms:google-services:3.2.1'


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

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
        google()
        jcenter()
    }
}

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

这是我的 build.gradle 模块:app

apply plugin: 'com.android.application'

    compileSdkVersion 27
    defaultConfig {
        applicationId "com.doctordirectory"

最佳答案

在将 firebase 依赖项 更新到最新版本(例如 com.google.firebase:firebase-core:15.0.0 到 com.google)后解决了这个问题.firebase:firebase-core:15.0.2 Get Latest List from here

以下列表中的所有其他更改

        implementation 'com.google.apis:google-api-services-people:v1-rev4-1.22.0'
    }

2) 在顶层 build.gradle 文件中更新 classpath 'com.google.gms:google-services:3.1.1 到 classpath 'com.google.gms:google-services:3.2.1

关于Android Studio-程序类型已经存在 : com. google.android.gms.internal.measurement.zzwp，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50146640/
