Check for step 1 and step 2.
You (Documentation Writers) have mentioned below:
1. In your project files in the left sidebar, locate Gradle Scripts > build.gradle (Module: app), then double-click the file to open it in the editor.
Note: Make sure not to open the first gradle file, which in my case is build.gradle (Project: My Sample App).
2. Before the dependencies section, add the following repositories section:
repositories {
maven { url 'https://zendesk.jfrog.io/zendesk/repo' }
}
Now let me tell you, what was wrong here. the above-mentioned code needs to add to the project level Gradle file, but you(or your documentation) said that add this code in the App level Gradle file (build.gradle (Module: app))
This is wrong. And because of this, I spent 2 weeks to resolve issue and connected over email with your support team!
