The UserIndicator from <MapboxGL.UserLocation>, work and display fine on IOS, but with android, it's depends, it sometime work, sometime not, and i realize also, that my CameraRef.current.setCamera() is undefined when the UserIndicator doesn't display.
I tried to request with all the way i could, the location permissions like this :
React Native :
PermissionsAndroid.requestMultiple(
[PermissionsAndroid.PERMISSIONS.ACCESS_COARSE_LOCATION],
{
title: 'Give Location Permission',
message: 'App needs location permission to find your position.'
}
).then((res) => console.log(res))
MapboxGL :
if (Platform.OS == "android") {
var temp = await MapboxGL.requestAndroidLocationPermissions()
}
expo :
let { status } = await Location.requestPermissionsAsync();
all this request permissions work fine and have a output "granted" or granted : true
this is my map Component :
var Map = ({ navigation }) => {
const MapRef = React.useRef(null)
const CameraRef = React.useRef(null)
const LocationRef = React.useRef(null)
const { user, setUser } = React.useContext(UserContext)
const [data, setDATA] = React.useState([null])
const [reload, setReload] = React.useState(false)
const {location, setLocation} = React.useContext(LocationContext)
console.log(location)
var test = null;
React.useEffect(() => {
MapboxGL.setTelemetryEnabled(false);
MapboxGL.locationManager.start();
return () => {
MapboxGL.locationManager.stop();
}
// console.log(LocationRef.current)
}, [])
function handleClick() {
CameraRef.current.setCamera({
centerCoordinate: [location.coords.longitude, location.coords.latitude],
zoomLevel: 11,
animationDuration: 200,
})
}
function CenterCamera() {
if (CameraRef.current) {
CameraRef.current.setCamera({
centerCoordinate: [location.coords.longitude, location.coords.latitude],
zoomLevel: 11,
animationDuration: 2000,
})
}
}
function goTo(latitude, longitude) {
CameraRef.current.setCamera({
centerCoordinate: [longitude, latitude],
zoomLevel: 13,
animationDuration: 100,
})
}
function DisplayPings(data) {
if (data.data.length > 0) {
if (data.data[0].type_id == null) {
data.data[0].type_id = 1;
}
const val = searchInJson(data.data[0].type_id)
const features = setFeatures(val, data.data[0])
return (
<View key={data.data[0].id_activity_data}>
<MapboxGL.Images
images={{
FootBall: json[0].url,
}}
/>
<MapboxGL.ShapeSource hitbox={{ width: 20, height: 20 }} onPress={() => goTo(data.data[0].latitude, data.data[0].longitude)} id={(data.data[0].id_activity_data).toString()} shape={features}>
<MapboxGL.SymbolLayer id={(data.data[0].id_activity_data).toString()} style={{ iconImage: ['get', 'icon'] }} />
</MapboxGL.ShapeSource>
</View>
);
}
}
if (location && location.city != null && data.data) {
return (
<View style={styles.page}>
<MapboxGL.MapView onPress={() => console.log("test")} ref={(ref) => {
}
} style={styles.map} compassEnabled={false} zoomEnabled={true} >
<MapboxGL.UserLocation />
<MapboxGL.Camera ref={(ref) => {
CameraRef.current = ref
CenterCamera()
}} />
{data.data.map((data) => DisplayPings(data))}
</MapboxGL.MapView>
<ComponentsOnmap></ComponentsOnmap>
<TouchableOpacity style={styles.rondLocation} onPress={handleClick}>
<FontAwesome5 name="location-arrow" size={24} color="#434040" />
</TouchableOpacity>
<BottomSheet city={location.city} data = {data} setReload = {setReload} navigation={navigation}></BottomSheet>
</View>)
}
else
return (
<View style={styles.page}>
<MapboxGL.MapView ref={MapRef} compassEnabled={false} style={styles.map} zoomEnabled={true} >
<MapboxGL.UserLocation ref={LocationRef} />
</MapboxGL.MapView>
<ComponentsOnmap></ComponentsOnmap>
<BottomSheet city="No location" navigation={navigation}></BottomSheet>
</View>
)
}
export default Map
My condition location && location.city != null works fine, i tried without it, but the problem is still the same
My Location Context :
import React, { Component, createContext, useState, useContext } from "react";
import { Platform, PermissionsAndroid } from "react-native"
import * as Location from 'expo-location';
import MapboxGL from "@react-native-mapbox-gl/maps";
import { GetLocation } from "../API/GetLocation"
export const LocationContext = createContext();
MapboxGL.setAccessToken("Je l'ai caché bande de petit malin");
export default LocationProvider = ({ children }) => {
const [location, setLocation] = useState({ coords: [], city: null, permission: false })
const [city, SetCity] = React.useState(null)
const [coords, setCoords] = React.useState([])
React.useEffect(() => {
PermissionsAndroid.requestMultiple(
[PermissionsAndroid.PERMISSIONS.ACCESS_COARSE_LOCATION],
{
title: 'Give Location Permission',
message: 'App needs location permission to find your position.'
}
).then((res) => console.log(res))
GetLocation.then((res) => {
setLocation(res)
})
}, [])
return (
<LocationContext.Provider value={{ location, setLocation, city, SetCity, coords, setCoords }}>
{children}
</LocationContext.Provider>
)
}
My GetLocation Promise
import { useContext } from "react"
import { Platform } from "react-native"
import * as Location from 'expo-location';
import MapboxGL from "@react-native-mapbox-gl/maps";
export const GetLocation = new Promise(async (resolve, reject) => {
if (Platform.OS == "android") {
var temp = await MapboxGL.requestAndroidLocationPermissions()
}
let { status } = await Location.requestPermissionsAsync();
if (status == "granted")
Location.getCurrentPositionAsync().then((location) => {
console.log(location)
console.log("ca marche ap")
let longitude = location.coords.longitude
let latitude = location.coords.latitude
return ({ latitude, longitude })
}).then(async (coords) => Location.reverseGeocodeAsync(coords).then(async (adress) => {
resolve({ coords: coords, city: adress[0].city, granted: true })
})).catch((error) => console.log(reject(error)));
})
