[问题解决]解决编译时，Androidx和其他三方库冲突

在Android Studio中新建项目使用Androidx库，如果此时使用的第三方库中包含旧版Support库，会导致冲突报错。

`Your project has set `android.useAndroidX=true`, but configuration `:app:debugAnnotationProcessorClasspath` still contains legacy support libraries, which may cause runtime issues.
This behavior will not be allowed in Android Gradle plugin 8.0.
Please use only AndroidX dependencies or set `android.enableJetifier=true` in the `gradle.properties` file to migrate your project to AndroidX (see https://developer.android.com/jetpack/androidx/migrate for more info).
The following legacy support libraries are detected:
:app:debugAnnotationProcessorClasspath -> com.jakewharton:butterknife-compiler:8.8.1 -> com.jakewharton:butterknife-annotations:8.8.1 -> com.android.support:support-annotations:25.3.0

解决办法为在project主目录下的gradle.properties中添加

android.enableJetifier=true
