当我在Android Studio中按播放按钮时,我的应用程序会编译,但会显示此错误(已编辑):

  

错误:程序类型已存在:android.arch.lifecycle.LiveData

(Full log)

我尝试删除.gradle文件夹,然后转到Build > Clean ProjectBuild > Rebuilt Project。但是,它不起作用。我还尝试删除源代码,然后再次从git克隆并将文件夹导入Android Studio。但是,它仍然会产生错误。

这是我的应用app/build.gradle

显然,这是预期的行为:

  

com.firebaseui:firebase-ui-firestore:3.1.0依赖于android.arch.lifecycle:extensions:1.0.0-beta1。切换到版本3.2.2通过使用支持库27.1.0构建的Lifecycle 1.1库来修复此问题。 - Issue Tracker

对我来说,删除firebase-ui依赖项解决了这个问题,因为我甚至没有首先使用该库。

今天,当我提出支持库版本时,我遇到了同样的问题。

尝试将'strong>所有 '27 .1.0'替换为'27 .0.2'

后来我确实设法通过升级其他库来删除错误。 这是我目前的工作状态: root gradle:

此帖子是最相似错误的顶部搜索结果:“程序类型已存在:android.arch.lifecycle。 ViewModelProvider $ Factory

我的项目使用Room和LiveData,但不使用Firebase。以下更改消除了该错误:

从:

implementation 'android.arch.persistence.room:runtime:1.0.0'
annotationProcessor 'android.arch.persistence.room:compiler:1.0.0'
implementation 'android.arch.lifecycle:extensions:1.0.0'
annotationProcessor 'android.arch.lifecycle:compiler:1.0.0'

收件人:

implementation 'android.arch.persistence.room:runtime:1.1.1'
annotationProcessor 'android.arch.persistence.room:compiler:1.1.1'
implementation 'android.arch.lifecycle:extensions:1.1.1'
annotationProcessor 'android.arch.lifecycle:compiler:1.1.1'

---更新的答案---

我先前的答案旨在解决此错误。但是,我认为最好用最佳实践再次介绍它:

应用程序级别的build.gradle文件:

// Room components
implementation "android.arch.persistence.room:runtime:$rootProject.roomVersion"
annotationProcessor "android.arch.persistence.room:compiler:$rootProject.roomVersion"
androidTestImplementation "android.arch.persistence.room:testing:$rootProject.roomVersion"

// Lifecycle components
implementation "android.arch.lifecycle:extensions:$rootProject.archLifecycleVersion"
annotationProcessor "android.arch.lifecycle:compiler:$rootProject.archLifecycleVersion"

项目级别的build.gradle文件:

ext {
   roomVersion = '1.1.1'
   archLifecycleVersion = '1.1.1'
}

Firebase-UI 3.1.0与Firebase / Google Services 11.8.0不兼容

您需要根据https://github.com/firebase/FirebaseUI-Android#compatibility-with-firebase--google-play-services-libraries

升级或降级
  • 使用Firebase / Google Services 11.4.2的Firebase-UI 3.1.0
  • 使用Firebase-UI 3.1.3的Firebase / Google Services 11.8.0

希望这个帮助;)

答案 4 :(得分:2)

我也在原始问题中发布了错误,即:

Error:Program type already present: android.arch.lifecycle.LiveData

目前还不清楚哪些库导致了问题。从@lienmt上面的提示我意识到它可能与Firebase有关。

就我而言,我使用的是Firebase,并且还使用了firebase-ui库3.2.2:

implementation 'com.firebaseui:firebase-ui-database:3.2.2'

我已将所有其他Firebase库升级到15.0.0,但实现了我的firebase-ui库不兼容并在此处确认:

https://github.com/firebase/FirebaseUI-Android#compatibility-with-firebase--google-play-services-libraries

请务必将您的firebase-ui版本与针对其进行配对的Firebase版本进行匹配。

将我的firebase-ui版本压缩到3.3.1是解决错误的原因:

implementation 'com.firebaseui:firebase-ui-database:3.3.1'

此处参考的是我现在使用的版本,我的应用程序正在运行且没有错误:

implementation 'com.google.android.gms:play-services-wearable:15.0.0'
implementation 'com.google.android.gms:play-services-auth:15.0.0'
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-database:15.0.0'
implementation 'com.google.firebase:firebase-core:15.0.0'
implementation 'com.google.firebase:firebase-auth:15.0.0'
implementation 'com.google.firebase:firebase-messaging:15.0.0'
implementation 'com.firebaseui:firebase-ui-database:3.3.1'

答案 5 :(得分:1)

请在您的应用程序build.gradel文件中添加以下依赖项

implementation "android.arch.core:runtime:1.1.1"
implementation "android.arch.core:common:1.1.1"

@Edric:因为我无法重播帖子中的图片,我在这里回答你的问题。

对我有用的变化:

Module Project level

PS:我还将gradle-wrapper.properties中的distributionUrl升级为 http://services.gradle.org/distributions/gradle-4.6-all.zip

答案 7 :(得分:0)

就像Edric所提到的,发生这种情况是因为某些库仍使用android.arch.lifecycle:extensions库的旧版本,即android.arch.lifecycle:extensions:1.0.0

一种解决方法是强制应用程序使用该库的相同版本(如果可以,请使用最新版本)。

有两种方法可以做到这一点:

  1. 在“依赖关系”部分下明确定义了我们要在Gradle中使用的库版本。

    implementation 'android.arch.lifecycle:extensions:1.1.1

  1. 该库的强制解析,也位于dependencies下。

    android {
        configurations.all {
            resolutionStrategy.force 'android.arch.lifecycle:extensions:1.1.1'
        }
    }
    

答案 8 :(得分:0)

就我而言,将targetSdkVersioncompileSdkVersion提升到28,并使用所有支持库的28版解决了该问题。


我在升级Glide时遇到了这个问题。我遇到关于duplicate CoordinatorLayout的错误。我通过使用com.android.support:design:27.1.0 solved来实现,但是随后又遇到了关于LiveData$LifecycleBoundObserver的另一个错误。

几个小时后,我放弃了targetSdkVersioncompileSdkVersion并将其升级到API 28,并使用

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'

因为YOLO。运气不好,它起作用了。

答案 9 :(得分:0)

只需升级即可。对我来说,我必须在App build.gradle文件中升级以下文件:

implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-auth:16.2.0'
implementation 'com.firebaseui:firebase-ui-database:3.2.2'

然后,您将同步文件。运行时,您会收到新的安装失败弹出框对话框。只需取消这些,然后执行以下操作即可:

1) Build -> Clean Project
2) Build -> Build Bundle(s) / APK(s) -> Build APK(s)
3) Run your project! Should work!
