Gradle implementation line is wrong.

Android does not download library with this gradle link
implementation 'com.github.stfalcon:stfalcon-imageviewer:v1.0.1'

Use this link.
implementation 'com.github.stfalcon-studio:StfalconImageViewer:v1.0.1'

In my case, I ended up with adding maven { url "https://jitpack.io" } to settings.gradle.
