React-native android studio Build Failed

Question

When I do build->rebuild project the build fails in the android studio. I have the error message posted below. This is very strange because I didn't change anything, all I tried was to create a new AVD and the next thing you know trying to build it causes an error. Now I can't get it to run. I am hesitant to try some random quick fix because everything was working fine until I created a new AVD.

Branch SDK is not properly imported in your React project.

https://docs.branch.io/pages/apps/react-native/

Follow YARN installation to add dependencies in the project.
