android - Access All Media Files on Internal Storage -

-

i'm using following example try load saved images , video on android device customized gallery activity:

access ordered images , video in same cursor

while works images , video created using default android camera app, doesn't seem find media files saved locally in folder app (located in pictures/name_of_app)

how can fetch media files on device?

private string[] projection = {             mediastore.files.filecolumns._id,              mediastore.files.filecolumns.data,             mediastore.files.filecolumns.date_added,             mediastore.files.filecolumns.media_type,             mediastore.files.filecolumns.mime_type,             mediastore.files.filecolumns.title     }; // used query contentresolver mediafiles      private string selection = mediastore.files.filecolumns.media_type + "="             + mediastore.files.filecolumns.media_type_image             + " or "              + mediastore.files.filecolumns.media_type + "="             + mediastore.files.filecolumns.media_type_video;  // used select images , videos contentresolver      private uri queryuri = mediastore.files.getcontenturi("external");     cl = new cursorloader(customizedgallery.this, queryuri, projection, selection, null, mediastore.files.filecolumns.date_added + " desc");

it sounds files haven't been added mediastore database yet. can check checking gallery app - if don't show there aren't in db yet.

simply creating them not automatically add them database - scans happen @ regular trigger points(such on reboot or remount of external storage) or can manually request rescan.

to request scan of particular file can call:

sendbroadcast(new intent(intent.action_media_scanner_scan_file, uri.fromfile(newfile)));

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
