项目中的清单合并失败问题

Question

以下是在输出控制台中弹出的错误。 总是弹出新错误。 打开任何类文件时，R上都会出现错误。无法解析符号R。请帮帮我。

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:7:5-74:19 to override.

遵循app:Gradle项目app:Gradle

apply plugin: 'com.android.application'

非常感谢您的时间和协助。

Answer 1

这是因为您的以下依赖项：

implementation "androidx.constraintlayout:constraintlayout:2.0.0-alpha1"

与以下内容发生冲突：

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

因为它们都具有相同的属性：

属性application @ appComponentFactory

您可以通过使用ConstraintLayout的支持版本来解决此问题：

implementation 'com.android.support.constraint:constraint-layout:1.1.3'

或使用AndroidX库更改所有支持库。
