Answer 1

Try to do this:

cd android

Answer 2

I had similar problem, and ./gradlew clean didn't work, but i found hacky solution from How can I regenerate ios folder in React Native project?

Delete android folder (probably ios too), and then hacky part ->:

react-native upgrade

And then

react-native link
react-native run-android

It worked for me :)

EDIT : one observation -> react-native sometimes goes crazy and cannot run some commands. Launching a new terminal helps. Bizarre :)
