I use Fyber Heyzap and do the instruction on Fyber page. https://developers.heyzap.com/docs/android_sdk_setup_and_requirements Then I added implementation 'com.fyber:fairbid:9.52.2' implementation zipTree(file('heyzap-ads-9.52.2.zip')) implementation 'com.google.code.gson:gson:2.8.1' to the build grade file. But build error: Could not find method implementation() for arguments [com.fyber:fairbid:9.52.2] on root project. What is wrong with me?
