}

构建项目时，出现错误“错误:包android.support.annotation不存在”

我尝试了以下解决方法。

在* .java文件中，我尝试注释并再次添加导入。

我尝试添加添加“androidx.annotation:annotation:1.1.0”

但仍然没有运气。

gradle.properties

org.gradle.jvmargs=-Xmx1536m
android.enableR8=true
android.useAndroidX=true
android.enableJetifier=true

非常感谢您的事先帮助，我已经坚持了很长时间，我们将不胜感激。

最佳答案

尝试从以下位置更改:

androidTestImplementation "com.android.support:support-annotations:28.0.0"

至

implementation "com.android.support:support-annotations:28.0.0"
