Download file remote address to device (storage internal if possible)

Hi all

I tried this for a few hours with different approaches now. Also looking through various forums did get me the result I needed.

Note: I can't use the built-in browser, it must be as lean as possible

First a (the desirable and easiest): don't-> not possible-> survey ClassCastException casting 'connection' return of Connector.open () on a "FileConnection.

FileConnection fc = (FileConnection) Connector.open("http://example.com/files/test.mp4", Connector.READ);

String remoteFileName = fc.getName();

String localFilePath = "file:///store/home/user/" + remoteFileName;
FileConnection fcLocal = (FileConnection) Connector.open(localFilePath, Connector.READ_WRITE);

if(!fcLocal.exists())
{
  fcLocal.create();
  DataOutputStream dos = fc.openDataOutputStream();

  DataBuffer db = new DataBuffer();
  db.write(fis);
  dos.write(db.getArray(),0,db.getArrayLength());
  dos.flush();
  dos.close();
}

Second :-> works for very small files (~ 2 k), but as soon as they are more 'fc.getLength ()' returns a value about 24 (= bytes). I guess that's not the good function to call here, although fc.getHeaderField (HttpHeaders.HEADER_CONTENT_LENGTH); Returns the same value.

HttpConnection fc = (HttpConnection) Connector.open("http://example.com/files/test.mp4", Connector.READ);

/// some stuff here to get the file name out of the url -> remoteFileName

String localFilePath = "file:///store/home/user/" + remoteFileName;FileConnection fcLocal = (FileConnection) Connector.open(localFilePath, Connector.READ_WRITE);

if(!fcLocal.exists()){  fcLocal.create();  DataOutputStream dos = fc.openDataOutputStream();

  DataBuffer db = new DataBuffer();  long fileSize = fc.getLength();

  for (long i = 0; i < fileSize; i++)  {    byte temp = dis.readByte();    db.writeByte(temp);  }

  dos.write(db.getArray(),0,db.getArrayLength());  dos.flush();              dos.close();    }

any suggestions? Maybe I just oversaw some nifty examples that resolves in a few lines.

Thank you

    How to recover files deleted from a removable storage device (memory stick)? the only folder to recycle bin is on my network drive, there is none on my memory stick.

    "Deleting" a file does not actually delete it marks just the space
    also available to be used. There are third-party programs that can
    sometimes recover deleted files. The problem is that the space used by
    the file is likely to be replaced very quickly, and it makes
    the unrecoverable file.

    So your chances of successfully recover this file are decent if you
    Try it again immediately after the deletion of it and go quickly
    downhill from there if you write other files on the device.

    But if the file is large enough, it's still worth a try. Stop
    written on the memory stick immediately, if you did not
    already. Download an undelete program (and here's one:)

  • Can not download files with adopted storage

    Anyone else using adopted storage in Marshmallow unable to download files? My SD card works fine, I can move applications to the SD card and application data cache which lives on the SD card also works very well. All my applications are functioning normally, if clearly no problem writing to the SD card.

    However, if I try to download a file - for example to download a file from the application Google Drive, or save an attachment in Gmail - all that would be found in the "Downloads" folder - it just fails. I get an error "unable to write to the storage."

    It cannot be a storage permissions problem, because it happens in any application that attempts to download the folder "Downloads" - and all of the apps I've tried already have granted permission of 'Storage'.

    Any ideas? Thank you!

    Don't worry, it's fixed. A simple reboot fixed it. Although worrying, had been removed a couple of days, I got a notification that says my SD card - even if everything seems to work properly. A restart which sets also.

    I just hope this isn't a sign that I'm developing a problem either with the SD slot on my phone or SD itself card. That's the problem with the aid of stoarge adopted - if the SD card fails, the entire phone actually fails!

    Fingers crossed everything is OK now if...

  • And then visualize it PhoneGap/Cordova download file to the device

    I'm doing a magazine app that downloads images to the device for the magazine can be read when offline or with a bad internet connection.

    I use PhoneGap/Cordova version 3.1 with 10 of BlackBerry and plugins file and file transfer. I made a few changes to my code base that runs on Android and iOS since before he could download files on the Simulator. Ensure the directory that I wanted to save the file to exist and access to the file with the path indicated in fs.root.toURL ().

    But now that I got the files uploaded to the device I can't view. On other platforms, I was able to use theFileEntry.toURL () and set it as the source for an img tag. But for BB10 I see only an empty img tag. =/
    The specified local path is: filesystem:local:///persistent/bblogo.png

    I was searched and seen references to disabling sandbox and by saving the file on blackberry.io.shared or blackberry.io.home, but blackberry is not available for me with PhoneGap 3.1. Looking at the native documentation , that I saw that the shared path is/accounts/1000/shared but trying to browse the file system I am told that the path does not exist. (fs.root.getDirectory ('accounts') to start with).

    I have a GitHub repository with what I'm looking for here: https://github.com/gaqzi/phonegap-bb10-file-transfer-test
    The code in question is here: https://github.com/gaqzi/phonegap-bb10-file-transfer-test/blob/master/www/js/index.js#L38

    I also noticed that the size of the file when the download is complete is much larger than the actual size of the file on my computer. And the same code running on iOS I see not enough to increase the size of the file. I don't know if that has to do any.

    To try to combat the current file size wildly different I coded an image 10 x 10 pixels as Base64, she decoded on the device and saved. Now, he pointed out the same size on my computer and the device, but still can not see. The same exercise done on iOS gives me a visible image.

    For the code on the test of Base64, please see my thread Stack Overflow for this: http://stackoverflow.com/questions/19421245/blackberry-10-cordova-phonegap-3-1-filetransfer-image-do...

    I am at a loss what can I do to access the files I created, anyone has an idea?

    Hello

    The patch for the cordova file api is still ongoing. Until that of land, here is an example for download of an image and inject it into the DOM. It uses XHR, but the filetransfer plugin should work as well.

    https://gist.github.com/jeffheifetz/c1127b4d3e132ffff972

    You will need to 'blackberry.io', which is available as plugin PhoneGap/Cordova here:

    https://github.com/BlackBerry/Cordova-BlackBerry-plugins/tree/master/plugin/com.BlackBerry.IO

    The patch will automatically update toURL so that it returns the full path which has been hard-coded in the example.

    Hi pjvconsulting,

    There is no restriction on the number of files that you can send.

    However, for a free & buy account you cannot exceed a limit of 5 GB and 20 GB storage, respectively.

    The size of a file may not exceed 2 GB.

    The error means that DW still think your Checkin/checkout is enabled.

    Follow these steps:

    1 using the site manager, create a NEW site definition that points to the same
    local and remote sites than your original.
    2. to connect to the remote site.
    3. find and DELETE all instances of *.lck at the remote site.

    Now, try to import the file. What is going on?

  • How to download files in mydomain_server_2

    Hi Experts,

    I have created java with 2 servers cs managed there in the clouds of the pub, at - it a way to download files, example: mydomain_server2.out server managed as not in the same box with the server administrator?

    And how to upload files to the server?

    Best regards

    Hello

    Yes, you can access other servers managed within your Cluster of JCS (not only the one who has the Server Admins exposed with public IP address) and move the files to/from it.

    Here are the high level steps:

    1. Copy your private ssh key to the administrator of the server (use opc user for the virtual computer and copy the key into the opc home folder)
    2. SSH on the administration as opc Server
    3. make sure that the private ssh key privileges are 600 (to avoid permissions errors)
    4.
