expo-file-dl's Issues

Unable to resolve module @unimodules/core

Am I missing something? I am running a managed Expo app, there is some information about react-native-unimodules but that is for Bare Expo and React Native apps.

iOS Bundling failed 5544ms

Have heard reports that scheduleNotificationAsync needs a seconds parameter in the trigger property as opposed to just the channelId. Need to test this out

downloadToFolder function on Android versions > 8

Hello,

I don't have a physical Android device that's capable of installing newer versions of Android OS beyond 8. For Android 8 and 7, the downloadToFolder function works as expected:

await downloadToFolder(uri, filename, 'my-apps-folder', channelId);

The 'my-apps-folder' gets created inside Android OS's Documents folder and the file is found. However, client testing with a newer Android OS doesn't see 'mp-apps-folder' inside Documents and it's no where to be found (and no downloaded file either). I'm wondering if anyone has any insights and experiences on any differences in behaviour between different versions of Android OS's.

For now my code is using default Notification settings, if that matters in any way.

Thanks

Media Permission is required to do this operation (IOS)

Hi,
I'm fairly new to iOS development and I'm using expo-file-dl 2.0.0 to download remote files on expo 41.0.0. It works great with non image file types but when I try to pull images I get the Error: MEDIA_LIBRARY permission is required to do this operation error.

My code looks like this:

let hasAccess = await MediaLibrary.getPermissionsAsync();
if(hasAccess.accessPrivileges.toLowerCase() == "all") {
  await downloadToFolder(
    "https://upload.wikimedia.org/wikipedia/commons/thumb/f/fe/Watermark_sample.jpg/1599px-Watermark_sample.jpg", 
    "test.jpg", 
    "Download", 
    "DownloadInfo");
}

I have verified that "hasAccess" is 'all' both in app and in the app settings. I've been looking at this for 2 days now and I can't figure out what I"m missing. Any idea what's going on?

PDFs are not downloaded, but sharing dialog is opened instead

Hi. Thanks for the great library.
Tried to download a PDF, but it's not downloaded at all in iOS. The native iOS sharing dialog is opened instead.

Can we get download progress feature

I need to show download progress in percentage so I need download progress feature to achieve it.

PS: Library is awesome working like charm.

A way to check if the file already exists

Is there a way to add a function to check if the file already exists in the folder?

Add option to move files from internal memory to the external directories

On Android the path to this is easy to see. What about on iOS? Need to look into that.

Suggested here: kathawala/expo-file-dl-example#7

Update the library to work with Expo 41 / Android R

Android R / Expo 41 / the latest version of Expo Go all expect the user to use Android SAF on devices that are using Android R.

Currently the library doesn't support this (and in fact will not work at all on Android with the current Expo Go on an Android R phone).

I need to add the ability to use SAF functions (https://docs.expo.io/versions/latest/sdk/filesystem/?redirected#storage-access-framework--android-only-) if the device is detected as having Android 11.

This does not affect iOS.

download finished message not showing in IOS when download pdf file

Download finished message not showing in IOS when download pdf file. But It work fine in Android.

No download complete notification when downloading a pdf

Hi,

I'm using the downloadtofolder function to download several file types on IOS. When I download images, everything works great but when I download non image files, the notifications don't seem to be quite right. When I initiate the download, a notification pops up saying that I'm initiating the download and opens up the save file dialog which is all good. But when the download completes, I don't get a notification. Any idea what I'm doing wrong?

My code:

 let customNotifInput: EDFL_NotificationContent = {
    downloading: { title: "Downloading", body: 'Downloading ', color: '#06004a' },
    finished: { title: "Complete", body: 'downloaded successfully', color: '#004a00' },
    error: { title: "Error", body: 'Error downloading', color: '#810002' }
  };

 let notificationOptions: EFDL_Options = { notificationType: {notification: "custom"}, notificationContent: customNotifInput }

 let url = "https://www.adobe.com/support/products/enterprise/knowledgecenter/media/c4611_sample_explain.pdf";
 
 await downloadToFolder(url, "test.pdf", "Download", channelId, notificationOptions);

Make notification optional

Make displaying downloading and download completed notification optional. For some us that would like to implement custom notification in our apps.

expose download http headers to API

I need to add an authorization header to download the file with a http request

This method has 3 parameters, but only 2 are exposed to the API:

expo-file-dl/src/index.ts

Line 148 in 5c98fe8

return await FileSystem.downloadAsync(uri, fileUri);
