capacitor-plugin-filedownload's Issues

Access downloaded files / specify the path of the downloaded file

So the package works fine, but it downloads my file (without being able to select the path) to /storage/emulated/0/Android/data/{appId}/files/{fileName}

How can I open this file instantly, or how can I make the plugin download the files to the Download folder of the device?

I'm trying to use the package to download .apk files (app updates) and install them.

English language not showing at downloading time.

how to display message in English language.

destination=EXTERNAL_STORAGE doesn't save the downloaded file

I'm having trouble getting files to download onto external storage on my Pixel 3a running Android 12. If I set destination=LIBRARY, the files go into the standard Downloads folder with no problems. But if I set destination=EXTERNAL_STORAGE and plug a USB drive into my phone (via a USB-OTG adapter), I get this error:

Error: download fail: /storage/emulated/0/img00001.jpg: open failed: EPERM (Operation not permitted)

I have granted my Ionic app permission to access "File and media". Is there another permission that needs approval for external storage?

Also, does the filedownload plugin support web apps? I've tried running "ionic serve" and launching the app in Chrome, but the HTTP download request is never sent. No error is thrown, the download() function just return the object {"path":""}. I'm guessing the plugin doesn't support PWAs, but just wanted to make sure.

File not appearing in gallery / file manager

I am downloading Images and videos, but files are not appearing in Gallery or File Manager:

response:

{
    "success": true,
    "path": "file:///storage/emulated/0/Android/data/com.company.appName/files/gallery-20230908040438_1694189077018.png"
}

Code:

writeFile = async (url: string) => {
    let parts = url.split('/');
    let name = parts[parts.length - 1];
    await FileDownload.download({
      url: url,
      fileName: name,
      headers: {},
      body: {},
      downloadTitle: 'downloading',
      downloadDescription: 'file is downloading',
      destination: 'DOCUMENT'
    }).then(async (res) => {
      console.log(res)
    }).catch(err => {
      console.log(err);
    })
  }

Storage permission popup response is ignored on Android

Hello, I am downloading a file on my application. It works perfectly, the file is downloaded and I can find it into files folders of ExternalStorage (cf screenshot 1).
But when I came back to the application there is a popup asking for storage permission. Is it normal behaviour to be able to download the file even if the result of the popup has not yet been answered? (cf screenshot 2)

Is there a way to handle the answer of the popup to prevent the downloading if the user refuses App to access storage ?

Tested : on Android 6.0.1 (Galaxy S5) and Android 12 (Pixel 3)

Not working in ios

don't change Http method to POST just because I add headers

Your documentation states that if I add headers you will change the http method from PUT to POST.

In your Android source you don't do that, in your iOS source you do. I believe the Android source is correct, and iOS is a bug - and it should only switch if you add a BODY; although I would perhaps suggest that you also give the user an option to specify what HTTP method they would like to use instead.

Reason being: I need to do a GET for my file, but I also need to add some headers for authorization, and some others things (changing the method is not an option). By adding this you switch the method to a POST which will fail. Plus as I stated above your Android and iOS behaviours differ.

From your Java source - note only changed based on the fact there is a body.

JSObject requestBodyObject = call.getObject("body", null);
if (requestBodyObject != null) {
  // code removed for clarity
  requestBuilder.method("POST", requestBody);
}

From your swift source - note changed even if I add a header

let method = !headers.isEmpty || body != nil ? HTTPMethod.post : HTTPMethod.get

Progress handler always returns 0 on iOS

The progress handler gets called, but I only get the value 0.

notifyListeners "downloadProgress" not implemented for android?

I want to notify the user the percentage of the download that has been completed, but I cannot access the process data in the listener.

const eventListener = await FileDownload.addListener('downloadProgress', data =>{
console.log(data.progress);
})

Is it possible to change destination folder?

I am trying to download a file to a folder, but it always sets it in files folder when using ExternalStorage on android, is it possible to store it in a subfolder?

Make destination type string

Instead of trying to map to specific folders for destination make it type string and accept a file path.

this way people can use capacitor file system plugin to get the base path (data, documents etc) and can add on their own sub folder if wanted.

filename just specifies the destination filename and you concat the 2 values to get the file path to save to.

you could add a check to make sure that destination exists before trying to download and reject if not.

Feature requests : if file already exist then just return file address not download again.

Every time download file if it already exist then just retrun path.
