Android failed to resolve host.expo.exponent:expoview:22.0.0

It was working fine before but today I facced this error.

How can I resolve it:

solved by putting android folder in .expo-source


I am bit new to react native, can you please explain it further. I am not able to find the ‘.expo-source’ folder. Is it a build in folder or do I need to create a new folder for the same. Thanks in advance.
