[Bug]: offlineManager.resetDatabase not clearing pack list

[borisyankov]

Mapbox Implementation

Mapbox

Mapbox Version

default

Platform

iOS, Android

@rnmapbox/maps version

10.0.15

Standalone component to reproduce

import { offlineManager } from '@rnmapbox/maps'
import React, { useEffect } from 'react';

function resetDBbug() {
  useEffect(() => {
    const resetDB = async () => {
      await offlineManager.resetDatabase();
      const packs = (await offlineManager.getPacks());
    }
    resetDB();
  }, [])
}

Observed behavior and steps to reproduce

When calling await offlineManager.resetDatabase() and then getting again the list of offline packs, the list remains the same.

This is true after having awated the response from the async resetDatabase and is true even if we wait for several seconds before calling offlineManager.getPacks().

Calling await pack.status() on any of these packs though will result in "Does not exist" exception.

Expected behavior

The result of await offlineManager.getPacks() should be an empty list, as the offline tile packs should have been cleared.

Notes / preliminary analysis

Restarting the app completely and calling getPacks() will return correctly an empty list.

Have you try close the app and open it again? Do the list have been gone?
I also stuck on same issue and manage to fix it!

@vishaldybot Have you tried to close the app after resetting the database or deleting the offline maps?

[vishaldybot]

@thdailong Yes, I have done everything and if possible can you please help with this?? as I am in the end of the project and now facing this issue. If you want I can share you how can you a standalone file with you so that you can try the same.

@vishaldybot It would be great if you could provide more information about the issue you are facing. I have facing a similar issue #3265 and managed to fix this bug.

@thdailong,` I was following samething but I was creating multiple offline packs. After that i want clear the all downloaded offlinemaps so i am calling offlineManager.resetDatabase() API, after calling api downloaded offline map names was not showing in console but in the app memory size (MB) not clearing and app memory size Increasing while downloading offline map everytime.

import geoViewport from '@mapbox/geo-viewport';
import Mapbox, {Camera,MapView,offlineManager,StyleURL,} from '@rnmapbox/maps;

import { Button, Dimensions, TextInput ,StyleSheet} from 'react-native';

const CENTER_COORD: [number, number] = [-73.970895, 40.723279];
const MAPBOX_VECTOR_TILE_SIZE = 512;
const STYLE_URL = Mapbox.StyleURL.SatelliteStreet;`


const Offline_Map = () => {
const [packName, setPackName] = useState('pack-1');
const [showEditTitle, setShowEditTitle] = useState(false);
return (

<>
<Button
title="Get all packs"
onPress={async () => {
const packs = await offlineManager.getPacks();
console.log('=> packs:', packs);
packs.forEach((pack) => {
console.log(
'pack:',
pack,
'name:',
pack.name,
'bounds:',
pack?.bounds,
'metadata',
pack?.metadata,
);
});
}}
/>
<Button
title="Remove packs"
onPress={async () => {
const result = await offlineManager.resetDatabase();
console.log('Reset DB done:', result);
}}
/>
<Button
title="Create Pack"
onPress={() => {
const { width, height } = Dimensions.get('window');
const bounds: [number, number, number, number] = geoViewport.bounds(
CENTER_COORD,
12,
[width, height],
MAPBOX_VECTOR_TILE_SIZE,
);
const options = {
name: packName,
styleURL: STYLE_URL,
bounds: [
[bounds[0], bounds[1]],
[bounds[2], bounds[3]],
] as [[number, number], [number, number]],
minZoom: 10,
maxZoom: 20,
metadata: {
whatIsThat: 'foo',
},
};
offlineManager.createPack(options, (region, status) =>
console.log('=> progress callback region:', 'status: ', status),
);
}}
/>
</>
);
}
export default Offline_Map;

In console after clicking the create pack

@sampathkumarch
I am not sure I can manage to solve this problem.
Perhaps, you can take a look at the local storage because I think offline map is located in that. Or you can ask @mfazekas

[sampathkumarch]

@thdailong thankyou for reply
I was looked at local storage i didn't find the file. Can looking in that.

[sampathkumarch]

@mfazekas, @thdailong can you help me with this point, am unable to delete the offline maps in the app memory.
