My problem was that the name I gave to the project was different from the name that was registered in the AppRegistry

AppRegistry.registerComponent('proj', () => proj)


proj

should be the same as the project name in gradle and config files.

You need to export the class. Use below code



 import React, { Component } from 'react' 
import { AppRegistry, Text, View } from 'react-native'
export default class proj extends Component {
 render() { 
return ( 
<View style={styles.container}> <Text > Welcome to PutainDeBiere! </Text> </View> ) 
} 
}
 AppRegistry.registerComponent('proj', () => proj)

Uninstall / uninstall APP first and then do a clean install and see if it works.
