React-native-fetch-blob: Download manager could not resolve downloaded file path.
Hi! Thanks for you module!
While development I have one issue, when I try to download file using addAndroidDownloads
Error: Error: Download manager could not resolve downloaded file path.
Status code: undefined
Here is my code:
.config({
addAndroidDownloads : {
useDownloadManager : true,
notification : false,
title: 'pdfurl-guide.pdf',
mime : 'application/pdf',
description : 'File downloaded by download manager.'
},
})
.fetch('GET', 'http://www.axmag.com/download/pdfurl-guide.pdf')
.then((resp) => {
console.log('DOWNLOAD complete');
RNFetchBlob.fs.exists(resp.path())
.then((exist) => {
console.log(`file ${exist ? '' : 'not'} exists`)
})
.catch(() => {
console.log('error while checking file for exists');
});
console.log(resp.path());
})
.catch((errorMessage, statusCode) => {
console.log('Error: ' + errorMessage);
console.log('Status code: ' + statusCode);
});
I check my path, and it return FOLDER exists
let path = RNFetchBlob.fs.dirs.DocumentDir;
RNFetchBlob.fs.exists(path)
.then((exist) => {
console.log(`FOLDER ${exist ? '' : 'not'} exists`)
})
.catch(() => {
console.log('error while checking FOLDER for exists');
});
Can you help me please ? Maybe I make mistake somewhere ?

Also i trying add path to adnroidDownloads config:
let path = RNFetchBlob.fs.dirs.DocumentDir;
RNFetchBlob.config({
addAndroidDownloads : {
useDownloadManager : true,
notification : false,
path: path + '/pdfurl-guide.pdf' ,
title: 'pdfurl-guide.pdf',
mime : 'application/pdf',
description : 'File downloaded by download manager.'
},
})
in this case I recive red screen with error:
Unsupported path /data/user/0/com.chat/files/pdfurl-guide.pdf
And also I trying download without addAndroidDownloads,
let path = RNFetchBlob.fs.dirs.DocumentDir;
RNFetchBlob
.config({
path: path + '/pdfurl-guide.pdf'
})
In this case it downloads, return path of file, but I can not find it on the device in the com.chat/files directory it is empty. But whe I check the file for existing
RNFetchBlob.fs.exists(resp.path())
.then((exist) => {
console.log(`file ${exist ? '' : 'not'} exists`)
})
.catch(() => {
console.log('error while checking file for exists');
});
It return that file is exist.
What I am doing wrong ?

@kholiavko-roman , Try to add file:// before the path.

@wkh237, I tried, but I still have an error.
I trying this path: file:///data/user/0/com.chat/files, also I tried to remove one slash before the data file://data/user/0/com.chat/files, but result the same - I have red screen with error
Unsupported path /data/user/0/com.chat/files/pdfurl-guide.pdf
let path = 'file://' + RNFetchBlob.fs.dirs.DocumentDir;
RNFetchBlob
.config({
path: path + '/pdfurl-guide.pdf',
addAndroidDownloads : {
useDownloadManager : true,
notification : false,
path: path + '/pdfurl-guide.pdf' ,
title: 'pdfurl-guide.pdf',
mime : 'application/pdf',
description : 'File downloaded by download manager.'
},
})
.fetch('GET', 'http://www.axmag.com/download/pdfurl-guide.pdf')
I found some tmp fix, If I set path to DownloadDir - I can download file without error.
let path = RNFetchBlob.fs.dirs.DownloadDir + '/pdfurl-guide.pdf';
And I found that when I set DocumentDir as in prev post, with or without file:// protocol, I recive red screen and on it path different from path that I see in the console.
Also I trying MainBundleDir - result the same.
Unsupported path /data/data/user/0/com.chat/files/pdfurl-guide.pdf
data/data in path duplicate.
I trying to set math manually without data, like this: /user/0/com.chat/files/pdfurl-guide.pdf
but I also revive an error, but on this time without duplicate /data/data/
Can you help me please?
_I tested on real devices with android 7.1 and 6.0_

I think this is a restriction as Android Download Manager only accepts a path on external storage.
see related SO thread

Ok, but if I need save file into the app directory, how I can do this without download managed ?
I tried, but app folder com.myapp is empty.

You can download the file with DownloadManager API then copy the file (fs.cp) to your app folder (DocumentDir)

@wkh237, can I download file in cash directory and open it after download ? I wanna just download image in cache and open it using actionViewIntent,
I tried to do this:
.config({
fileCache : true,
appendExt : 'jpg'
})
.fetch('GET', attachItem.url)
.then((resp) => {
console.log(resp);
console.log(resp.path());
RNFetchBlob.fs.exists(resp.path())
.then((exist) => {
console.log(`file ${exist ? '' : 'not'} exists`)
})
.catch(() => { console.log('err while checking') });
if (Platform.OS === 'ios') {
RNFetchBlob.ios.openDocument(resp.path());
} else {
RNFetchBlob.android.actionViewIntent('file://' + resp.path(), 'image/jpg');
}
})
.catch((errorMessage, statusCode) => {
console.log('Error: ' + errorMessage);
console.log('Status code: ' + statusCode);
});
After downloading I see the path with extension /data/user/0/com.chat/files/RNFetchBlobTmp_0boqybb710yu9tyaknbt48w.jpg
and after checking on existing file result - file exists
but when I opened image using default gallery app I can not see it.
The same code on ios works fine. How to save image in cache and open it ?

If I setup path to the RNFetchBlob.fs.dirs.CacheDir, I cant open file using actionViewIntent, but if I set path to the DownloadDir, or DCIMDir I can open file via actionViewIntent.

You can download the file with DownloadManager API then copy the file (fs.cp) to your app folder (DocumentDir)
@wkh237, also I tried to copy from download directory to DocumentDirs, but it it was not successful, document dirs are empty. ( I tried to move or copy it, and save it directry to DocumentDir or save in sub folder in DocumentDir - result the same, I see in console that file moved, but in my app directory is nothing change)
RNFetchBlob.fs.mv(resp.path(), RNFetchBlob.fs.dirs.DocumentDir + '/test/qq.jpg')
.then(() => {
console.log('file moved');
})
.catch(() => {
console.log('err while moving');
});

@romreed @LtkStark Every time the control is going to catch block with the error Error: Download manager could not resolve downloaded file path. and the file is getting downloaded. I want to know the res.path() of the downloaded file.
Here is my code
const dirs = RNFetchBlob.fs.dirs;
const filePath = `file://${dirs.DownloadDir}/${caption}.pdf`;
const configOptions = {
addAndroidDownloads: {
useDownloadManager: true,
mime: 'application/pdf',
description: 'File downloaded by download manager.',
path: filePath
}
};
RNFetchBlob
.config(configOptions)
.fetch('GET', srcUrl)
.then((res) => {
console.log(res.path());
})
.catch((err) => {
console.log(err);
});
platform : Android

removing file:// in the file path solved the issue.
thallamsai
on 13 Jun 2018
set the path in addAndroidDownoload, not directly in config
work
let savePath = RNFetchBlob.fs.dirs.DownloadDir + '/video.mp4'
RNFetchBlob
.config({
fileCache: true,
addAndroidDownloads: {
useDownloadManager: true,
notification: true,
title: 'video.mp4',
mime: 'video/mp4',
description: 'download description',
mediaScannable: true,
path: savePath,
}
})
.fetch('GET', url)
.then(res => {
let downloadPath = res.path()
console.log(downloadPath)
})
.catch(err => {
console.log(err)
})
don't work ,
llet savePath = RNFetchBlob.fs.dirs.DownloadDir + '/video.mp4'
RNFetchBlob
.config({
fileCache: true,
path: savePath,
addAndroidDownloads: {
useDownloadManager: true,
notification: true,
title: 'video.mp4',
mime: 'video/mp4',
description: 'download description',
mediaScannable: true,
}
})
.fetch('GET', url)
.then(res => {
let downloadPath = res.path()
console.log(downloadPath)
})
.catch(err => {
console.log(err)
})
