I assume that the Safari extension Gallery provides a plist update manifest just like you have to provide one for a self-hosted extension.
But what is its URL?

I am trying to implement something in react native:
I have a url of video which i'm showing in react native video component, how can i give a button to download that same video in mobile but it should not appear in gallery.
Also if the video is private where the headers can be passed and how?
How to download any file ?
Well for downloading any file like video,img you first need permission to read and write into internal/external storage of phone and after that you need a native module that can download files from server to the local folders of phone.
there are two best known libraries for downloading files
https://www.npmjs.com/package/react-native-fs
https://www.npmjs.com/package/react-native-fetch-blob
Now you can follow their documentation to download files like Videos,images or whatever you want to your user's phone.
Now Lets come to the part that you dont want it to be available to user via gallery.
For this i suggest using react-native-fetchblob as it has builtin intent actions and views.
You can download a video file with any random name like 1234CACHE any random name without any extension to it, specially dont give it extension like video.mp4 because gallery detects .mp4 files so dont give it any extension and the file won't be available in any gallery.
Now how to hide the file?
react-native-fetch-blob allow us to save files into directories that are not publicly available i mean user cannot reach those directory and these directories are used only for saving App's data so you can save your video file in one of these directories.
Now after completing your download, You can open your file with the Intent.
For Example:-
const VIDEO_PATH = res.path() //the path where your downloaded video is saved, you will actually receive this in the response of download function.
const MIME_TYPE = "video/mp4"
//Now finally call the intent with video mime so the video will be opened in user's media player, or if you want your own media player you can use any library for that.
android.actionViewIntent(VIDEO_PATH , MIME_TYPE)
Note: You can only download a video if you have a path URL to the video file, You must not mix web URL with Video File URL, Video file url has file name and video extension at the end of the url. such as https://someURL.com/video.mp4 this is video file url, but if you have something like https://SomeURL.com/video it is not a video file instead it is a webpage displaying that video file so you cant really download that specific video from a webpage!.
There can be multiple approaches to this.
I hope you have an idea about your video player, download option depends on your server and site.
You can change the file extension of downloaded video, like my_video.notMP4. So the video will not show in the Gallery as it not detected as a video file now.
Hide the folder where the video file is downloaded, adding a dot(.) before the folder name can hide the folder in Android/Unix and video will be hidden from Gallery. Example .my_Video_folder
For more safety, you can encrypt the video and make them in custom chunk which only your player can play. But you may need to make or find such a video player.
I could not understand the headers part, please explain.
It says in the Opera API (Formats: Manifest Files):
homepage_url
The URL of the homepage for this extension. The extensions management page will contain a link to this URL. If you distribute your extension using the Opera addons site, the homepage URL defaults to the extension's own page.
But from using ExtensionInfo.hompageUrl, those extensions without homepage_url in manifest will just give blank instead of its Opera addons site url.
On Chrome's side it works as expected.
It's a bug. I've just reported that. Thank you for the info!
Im developing an iPhone App that downloads an .html file from an ftp server. Is it possible to edit the html file before rendering it in an UIWebView? The html file contains data that is not relevant so I would like to delete part of the content. If so, how would I achieve this?
In a few steps:
Perform the FTP request yourself, using NSURLConnection.
Get the HTML into a string, and modify it.
Invoke -loadHTMLString:baseURL: to pass the modified document to the UIWebView.
I'm building an app that comunicate with a Web Service and I'm trying to download files from it.
I found that, after sending an appropriate request to the server, if the link of the UIWebView contains "DownloadFolder", that's the correct download link; sending an async request with that url the download works well for files like .pdf .doc .xls and so on..
The problems came when i send a request for a media file like mp3 mov and so. The webview work well and display the player, but I can't get the url from the webview.
I also noticed that in the consolle is displayed a line like this:
setting movie path: http://xxx.xxx.xxx.xxx/WEBSERVER/DownloadFolder/NAMEOFWEBSERVER/ADMIN/FA29-12-2011-12-57-04-163pitorb45sluo0g455wwc3u55.mp3
That's the URL I want to use for the download. How can i get it from code?
Thanks in advance.
I have used the info in this great post How do I associate file types with an iPhone application? to get my app launching from Mail with both mydoc.foo and the compressed version mydoc.foo.zip which auto-magically decompresses into my apps sandbox.
I can open a url such as http://blah.com/shared/mydoc.foo into my app with Safari but when the url is http://blah.com/shared/mydoc.foo.zip I get the message Unable to open Document when I use the Open in MyApp button on the loaded page.
Im wondering what needs adding to my info.plist to get this particular URL working as Safari recognises my app as the receiver for this extension set and Mail behaves perfectly well.
Its not hitting the
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url delegate method.
Since you want to accept .zip files and the page you've linked accepts .gz files, make sure you've specified a com.pkware.zip-archive UTI instead of org.gnu.gnu-zip-archive.
