Ian Clelland commented on CB-8103:
----------------------------------

The mime type of the file doesn't depend on the filename at all -- they sho=
uld be completely separate things.

Cordova uses [{{android.content.ContentResolver.getType}}|http://developer.=
android.com/reference/android/content/ContentResolver.html#getType(android.=
net.Uri)] to determine the type of the file, which should be correct, accor=
ding to its actual contents.

(However, 3GPP and MP4 are both extensions of the same spec (MPEG-4 part 12=
) and may actually be compatible in some cases, regardless of the extension=
 or the detected mime type.)

>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Android, Plugin File
>    Affects Versions: 3.6.3
>            Reporter: W. Matthew Wilson

> I have a feature in my app where a user can pick a video from their galle=
ry and then upload it to a remote server.
> I need the mime type of the file because right now, I can only process .m=
p4 files, not .3gp files.
> I'm using something like this code:
> {code}
> window.resolveLocalFileSystemURL(
>     local_video_path, // something like "/media/external/video/media/971"
>     function (f) {
>         console.debug("inside resolveLocalFileSystemURL callback", f);
>         f.file(function (fo) {
>             console.debug("fo", fo);
>             if (fo.size > 30 * 1000 * 1000) {
>                 navigator.notification.alert("Sorry, that file is too big=
!  Pick one less than 30 mb.");
>             } else if (fo.type =3D=3D "video/3gpp") {
>                 navigator.notification.alert("Sorry, that file is a .3gp =
file and we can't handle those!");
>             } else {
>                 // handle file...
>             }
>         });
> {code}
> And when I pick a file that ends with .mp4, in the file(...) function cal=
lback the mime type is set to 3gpp:
> {code}
> inside resolveLocalFileSystemURL callback=20
> FileEntry {isFile: true, isDirectory: false, name: "971", fullPath: "/med=
ia/external/video/media/971", filesystem: FileSystem=E2=80=A6}
> filesystem: FileSystem
> fullPath: "/media/external/video/media/971"
> isDirectory: false
> isFile: true
> name: "971"
> nativeURL: "file:///storage/emulated/0/DCIM/Camera/20141117_122122.mp4"
> __proto__: utils.extend.F
>  phonegapsend.js:818
> fo=20
> File {name: "content", localURL: "content://media/external/video/media/97=
1", type: "video/3gpp", lastModified: 1416244890, lastModifiedDate: 1416244=
890=E2=80=A6}
> end: 16515092
> lastModified: 1416244890
> lastModifiedDate: 1416244890
> localURL: "content://media/external/video/media/971"
> name: "content"
> size: 16515092
> start: 0
> type: "video/3gpp"
> __proto__: Object
> {code}
> That's not a very pretty example, but I do resolveLocalFileSystem on a fi=
le "/media/external/video/media/971", and the native URL for that file is "=
file:///storage/emulated/0/DCIM/Camera/20141117_122122.mp4".
> Then I use the file(...) method to look up the size and the type of that =
file, I get told that the type is "video/3gpp".  That doesn't make sense to=
 me!
> Am I doing something wrong or is this a bug?
> Let me know if there is more information I should provide.
> Go PhoneGap!
