How to download file to Download's directory with Ionic Framework?

Question

I'm trying with ngCordova but the cordova.file.documentsDirectory property is null.

I have also tried combining the use of ngCordova with requestFileSystem, but still, the file is not saved in the "Download's".

Example of my code:

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(directory) {
    var fileTransfer = new FileTransfer();
    fileTransfer.download(
        encodeURI("http://example.com/sample.pdf"),
        directory.root.nativeURL + 'sample.pdf',
        function(entry) {
            console.log("download complete: " + entry.fullPath);
        },
        function(error) {
            console.log("download error source " + error.source);
            console.log("download error target " + error.target);
            console.log("upload error code" + error.code);
        },
        false
    );
}, function(err){console.error(err)});

Thanks.

Solution 1

cordova.file.externalRootDirectory + '/Download/' + 'sample.pdf' instead of directory.root.nativeURL + 'sample.pdf'

Solution 2

I solved it via the following code:

const ROOT_DIRECTORY = 'file:///sdcard//';
const downloadFolderName = 'Download';


this.file.createDir(ROOT_DIRECTORY, downloadFolderName, true)
  .then((entries) => {
 //then your code
 fileTransfer.download(fileLocation,this.ROOT_DIRECTORY+this.downloadFolderName+'/'+ 'sample.pdf').then((entry) => {
}
//ends of your code ^^
})
  .catch((error) => {
    alert('error' + JSON.stringify(error));
  });

This Question is about download file to "Downloads folder" of Android, not about "cordova.file.documentsDirectory null". Definitely, you answer is too poor and not is constructive.

You said "I'm trying with ngCordova but the cordova.file.documentsDirectory property is null"

[Jorge Olaf]

Yes, and I says "also tray with "also tried combining the use of ngCordova with requestFileSystem". This question not is about documentsDirectory, is about How I can download file and store it on "Downloads Folder" on Android.

[Jorge Olaf]

This look much better. I'll try it. Thanks! +1

@OlafErlandsen No problem. Check cordova.apache.org/docs/en/latest/reference/…

[Jorge Olaf]

This answer works perfectly. I clarify that it is necessary to add write permissions for the application, otherwise it will not be able to download. Thanks @WadeTyler

[Wade Tyler]

@OlafErlandsen No problem. Glad to help.

@OlafErlandsen Can you tell me what permission I need for Download directory? I am getting /storage/emulated/0/Download/montages.json: open failed: EACCES (Permission denied). I have tried READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE and MANAGE_DOCUMENTS permissions. Did not helped :/

[Jorge Olaf]

Well, whats Android version are using you?

@Luckylooke Have you found a solution for this ? I am facing the same issu e

[Luckylooke]

@noor yes I have succeeded with combination of manifest permissions and cordova-plugin-android-permissions for runtime permissions needed for android 5+
