You can add a listener for the same in react native.

There are total 4 listners for the same.

1. willFocus - the screen will focus
   
2. didFocus - the screen focused (if there was a transition, the transition completed)
   
3. willBlur - the screen will be unfocused
   
4. didBlur - the screen unfocused (if there was a transition, the transition completed)
   

Try the below code

componentWillMount(){
    const didFocusSubscription = this.props.navigation.addListener(
      'didFocus',
      payload => {
        console.warn('didFocus ', payload);
        # just write your code/call a method here which you want to execute when the app comes from background
      }
    );
}

Dont forget to remove it when it is done.

componentWillUnmount(){
    didFocusSubscription.remove();
}
