Question

现在我正在尝试从git运行克隆应用程序https://github.com/frinder/frinder-app但问题是该应用程序制作了很长时间，所以应该改变bulid.gradle

但是当我尝试相同的同步实现“com.android.支持：动画矢量可绘制：28.0.0”，但如果我删除它，请继续向我显示错误28.0.0它显示如下

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.0.2. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-media-compat:27.0.2 more...

但我不知道是什么造成了不完全相同的版本

这是应用程序build.gradle（模块）

Gradle may disable incremental compilation as the following annotation processors are not incremental: butterknife-compiler-8.4.0.jar (com.jakewharton:butterknife-compiler:8.4.0), parceler-1.1.6.jar (org.parceler:parceler:1.1.6), auto-service-1.0-rc2.jar (com.google.auto.service:auto-service:1.0-rc2).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.

Answer 1

使用

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

没有版本28

Answer 2

您为约束布局定义的版本不可用。使用下面显示的一个。

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

更多信息在约束布局下面的链接中给出
