My project displays a react native map and asks for user location. In development the application runs nickel without error or bug or slowdown while when I build the app and install it when the application crashes.
Demo1 : DEMO gif app in developpement npx expo start: works fine Demo2 : DEMO gif app builded installed with apk: crash
I use :
"react-native": "0.70.5", "expo": "~47.0.12" "expo-location": "~15.0.1", "@react-native-community/geolocation": "^3.0.4", "react-native-maps": "^1.3.2",
My file that contains my map :
import React, { useEffect, useRef, useState } from "react";
import {
...
} from "react-native";
import { StatusBar } from "expo-status-bar";
import * as Location from "expo-location";
import MapView, { Marker } from "react-native-maps";
import { Alert } from "react-native";
const Planisphere = () => {
const [location, setLocation] = useState(null);
const [errorMsg, setErrorMsg] = useState(null);
const [mapRef, setMapRef] = useState(null);
const [locationAccepted, setLocationAccepted] = useState(false);
useEffect(() => {
(async () => {
let { status } = await Location.requestForegroundPermissionsAsync();
if (status !== "granted") {
setErrorMsg("Permission to access location was denied");
Alert.alert(
"Location Permission Denied",
"Please go to settings and enable location permission for this app to continue.",
[
{
text: "Go to Settings",
onPress: () => Linking.openSettings(),
},
]
);
return;
}
let subscription = await Location.watchPositionAsync(
{ accuracy: Location.Accuracy.BestForNavigation },
(location) => {
setLocation(location);
setLocationAccepted(true);
}
);
return () => subscription.remove();
})();
}, []);
const handleFindMyLocation = () => {
...
};
const handleUnzoom = () => {
...
};
let text = "Waiting..";
if (errorMsg) {
text = errorMsg;
} else if (location) {
text = JSON.stringify(location);
}
return (
<View style={styles.container}>
<StatusBar style="auto" />
{location && (
<MapView
ref={(ref) => setMapRef(ref)}
style={styles.map}
minZoomLevel={8}
maxZoomLevel={18}
initialRegion={{
latitude: location.coords.latitude,
longitude: location.coords.longitude,
latitudeDelta: 0.0922,
longitudeDelta: 0.0421,
}}
>
<Marker
coordinate={{
latitude: location.coords.latitude,
longitude: location.coords.longitude,
}}
title={"Your location"}
/>
</MapView>
)}
<Text style={styles.paragraph}>{text}</Text>
{locationAccepted && (
<View>
<Button title="Find my location" onPress={handleFindMyLocation} />
<Button title="Unzoom" onPress={handleUnzoom} />
</View>
)}
</View>
);
};
const styles = StyleSheet.create({
...
});
export default Planisphere;
My file ask location and when its authorized, the map appear.
UPDATE :
useEffect(() => {
const fetchPermission = async () => {
try {
const { status } = await Location.requestForegroundPermissionsAsync();
setPermissions(status);
if (status !== "granted") {
setErrorMsg("Permission to access location was denied");
}
} catch (err) {
setErrorMsg(err.message);
}
};
fetchPermission();
}, []);
useEffect(() => {
const fetchLocation = async () => {
if (permissions === "granted") {
const watcher = await Location.watchPositionAsync(
{ accuracy: Location.Accuracy.BestForNavigation },
(location) => {
setLocation(location);
setLocationAccepted(true);
}
);
setSubscription(watcher);
}
};
fetchLocation();
return () => {
if (subscription) {
subscription.remove();
}
};
}, [permissions]);
