错误:程序类型已存在:android.arch.lifecycle.LiveData [英] Error:Program type already present: android.arch.lifecycle.LiveData

问题描述

当我在Android Studio中按下运行按钮时，我的应用程序会编译，但显示此错误(已编辑):

When I press the run button in Android Studio, my app compiles but shows this error (redacted):

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

(完整日志)

我尝试删除.gradle文件夹，然后转到Build > Clean Project和Build > Rebuild Project.但是，它不起作用.我也尝试删除源代码，然后再次从git克隆并将文件夹导入Android Studio.但是，它仍然会产生该错误.

I've tried deleting the .gradle folder, then going to Build > Clean Project and Build > Rebuild Project. However, it doesn't work. I've also tried deleting the source code, then cloning again from git and importing the folder to Android Studio. However, it still produces that error.

这是我的应用程序的app/build.gradle:

apply plugin: 'com.android.application'

    compileSdkVersion 27
    buildToolsVersion '27.0.3'
    defaultConfig {

    }

    }
}

推荐答案

显然，这是预期的行为:

Apparently, this is intended behavior:

com.firebaseui:firebase-ui-firestore:3.1.0取决于android.arch.lifecycle:extensions:1.0.0-beta1.切换到版本3.2.2可以通过使用构建了支持库27.1.0的Lifecycle 1.1库来解决此问题. -问题跟踪器

对我来说，删除firebase-ui依赖项解决了这个问题，因为我一开始甚至都没有使用该库.

For me, removing the firebase-ui dependencies solved the issue since I wasn't even using the library in the first place.
