Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

How to win?

Answer 1

In this case, no devices were connected or virtually started, which is the main reason for this error.
Verification
In the English-language official documentation, it is written about this,
facebook.github.io/react-native/docs/getting-start...
But in the Russian translation, for some reason, they decided to skip that the emulator should be running. As a result, a lot of questions and this site gives out in the forefront, so the answer to google is not the best possible given the inconsistency of the issuance.
