ionic-v1

Hi

Can anyone help me please.
In my Ionic1 App, I would like to open a pdf-document which is located on an usb-drive which is connected to the mobile device.

How would I achieve this ?

Kind Regards
Joost

use file plugin and specify path of USB device as external memory to manage any type of file.

Would you have a code sample to achieve this ?

just read the document mentioned in bellow link. The directory structure of Android device is also mentioned in it. You certainly can do it with proper reading.

Hi

Via the properties of the cordova-file-plugin you cannot access the usb-drive.
I hope someone else can help me out.

How can I access a directory / file on the usb-drive which is connected to the device ?

The root for the files on USB drive(External Source) will be / as per document of plugin.

So how would you change following code to be able to read the contents of the usb-drive ?

    vm.leesDir = function leesDir(path) {
        $window.resolveLocalFileSystemURL(
            cordova.file.externalRootDirectory,
            function (dirEntry) {

                var dirReader = dirEntry.createReader();

                dirReader.readEntries(
                    function (entries) {
                        console.dir(entries); // directory entries
                    },
                    function (err) {
                        console.log(err);
                    }
                );

            },
            function (err) {
                console.log(err);
            }
        );
    };

How are you calling this function

It was originally :

vm.leesDir = function leesDir(path) {
$window.resolveLocalFileSystemURL(
path,
function (dirEntry) {

            var dirReader = dirEntry.createReader();

            dirReader.readEntries(
                function (entries) {
                    console.dir(entries); // directory entries
                },
                function (err) {
                    console.log(err);
                }
            );

        },
        function (err) {
            console.log(err);
        }
    );
};

and calling via

leesDir(’/storage/’);
or
leesDir(‘file:///storage/’);

When I connect the USB-drive, the files are located on

/storage/02DD-A5BD/

So when I call leesDir(’/storage’), I would like to get a listing of ‘/02DD-A5BD’ with it’s files and subfolders.
However this doesn’t seem to work.

There is no SdCard inserted at this moment.
