Pedometer.watchStepCount is not working on Android

Summary

Pedometer.watchStepCount is not working on Android 11, tested on Samsung A71 and A51. Pedometer.isAvailableAsync() is returning true But the callback of Pedometer.watchStepCount never triggers, no matter how many steps I walked. It worked well in iOS.

Reproducible demo or steps to reproduce from a blank project

You can test with the pedometer demo on the https://docs.expo.io/versions/latest/sdk/pedometer/ Or you can use my code

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { Pedometer } from 'expo-sensors';

export default class App extends React.Component {
  state = {
    isPedometerAvailable: 'checking',
    pastStepCount: 0,
    currentStepCount: 0,
  };

  componentDidMount() {
    this._subscribe();
  }

  componentWillUnmount() {
    this._unsubscribe();
  }

  _subscribe = () => {
    this._subscription = Pedometer.watchStepCount(result => {
      this.setState({
        currentStepCount: result.steps,
      });
    });

    Pedometer.isAvailableAsync().then(
      result => {
        this.setState({
          isPedometerAvailable: String(result),
        });
      },
      error => {
        this.setState({
          isPedometerAvailable: 'Could not get isPedometerAvailable: ' + error,
        });
      }
    );

    const end = new Date();
    const start = new Date();
    start.setDate(end.getDate() - 1);
    Pedometer.getStepCountAsync(start, end).then(
      result => {
        this.setState({ pastStepCount: result.steps });
      },
      error => {
        this.setState({
          pastStepCount: 'Could not get stepCount: ' + error,
        });
      }
    );
  };

  _unsubscribe = () => {
    this._subscription && this._subscription.remove();
    this._subscription = null;
  };

  render() {
    return (
      <View style={styles.container}>
        <Text>Pedometer.isAvailableAsync(): {this.state.isPedometerAvailable}</Text>
        <Text>Steps taken in the last 24 hours: {this.state.pastStepCount}</Text>
        <Text>Walk! And watch this go up: {this.state.currentStepCount}</Text>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop: 15,
    alignItems: 'center',
    justifyContent: 'center',
  },
});

Same on Google Pixel 5 with Android 11 and latest sdk 42 (with either my own code or from the snack on the official doc). This is probably a Permission issue as Expo App have not the permission to access my fitness data. Calling getPermissionsAsync or requestPermissionAsync returns Authorized but does not request for permission at all.

I confirmed that this is a permission issue, we need a fitness permission in order to use the fitness data. I solve this by using a react native module https://github.com/zoontek/react-native-permissions. This is the best permission requesting module as it includes the latest permission. Even the official rn permission module from react native doesn’t include activity permission. expo please update the permission module
