Getting file from content uri for videos taken

I have a method below:
private String getRealPathFromUriForVideos(Uri selectedVideoUri) {
String wholeID = DocumentsContract.getDocumentId(selectedVideoUri);
String id = wholeID.split(":")[1];
String[] column = { MediaStore.Video.Media.DATA };
String sel = MediaStore.Video.Media._ID + "=?";
Cursor cursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, column, sel, new String[]{ id }, null);
String filePath = "";
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
return filePath;
}
This works just fine getting the file for videos that hte user selects. However, I want to allow users to also create new videos (from my app) and then get the URI and the file from there. The URI for newly created videos is: content://media/external/video/media/41. For selected videos is like content://com.android.providers.media.documents/document/video%3A42.
It works with the second one but not the first one. First one I get IllegalArgumentException because its not a document URI. How can I get the file from the first URI?

This works just fine getting the file for videos that hte user selects
It may work in a few situations. It will not work in general. A Uri that you get from something like ACTION_OPEN_DOCUMENT does not have to represent a file, let alone one that you can access via the filesystem, let alone one that this script-kiddie algorithm will let you access.
The URI for newly created videos is: content://media/external/video/media/41
Not necessarily. I suppose that there is a way that you get a Uri like that for a recorded video, though off the top of my head I cannot think of a recommended way that would give you such a Uri. If you are using MediaRecorder or ACTION_VIDEO_CAPTURE, you create your own file (and, for ACTION_VIDEO_CAPTURE, your own Uri for that file). And, if you are creating your own file, you know where that file is.
Need to be able to upload to my server
For the video, record to a file that you control, then use that file.
Use some library that lets you upload from a Uri or InputStream. Otherwise:
Use ContentResolver and openFileInput() to get an InputStream on the content represented by the Uri
Create a FileOutputStream on some file that you control (e.g., in getCacheDir())
Copy the content from the InputStream to the OutputStream
Use your copy for the upload
Delete your copy when the work is done
You treat a foreign Uri as if it were a URL to a Web server: stream the content.

Seems to get it from the second URI I need this:
private String getRealPathFromUriForImagesAndVideo(Uri contentUri) {
Cursor cursor = null;
try {
String[] proj = {MediaStore.Images.Media.DATA};
cursor = getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} catch (Exception e) {
return contentUri.getPath();
} finally {
if (cursor != null) {
cursor.close();
}
}
}

Get a Content URI from a File URI?

I am using the DownloadManager to download an image to the system's gallery and then in the Broadcast receiver (once the download succeeds) using an Intent to set the image as the wallpaper.
Everything was working fine but then recently on 4.4 I started to get an exception in the Photos/Google+ app because it is expecting a content URI and not a file URI.
So my question is if anyone knows how to convert a full file path/URI (file://) into a content style URI (content://)?
Sorry for the lack of source code, I am away from the computer that has the source, but I hope the question makes sense without it, get a content style uri from a full path.
EDIT:
The image is copied into the system's gallery or media gallery, not saved within my apps internal storeage.
Here is an example of what I want to convert:
file:///storage/emulated/0/Pictures/Rockstar/image.jpg
to
content://media/internal/images/media/445
EDIT 2:
Here is the error that I get from the Google+ app:
04-21 10:50:35.090: E/AndroidRuntime(7220): FATAL EXCEPTION: main
04-21 10:50:35.090: E/AndroidRuntime(7220): Process: com.google.android.apps.plus, PID: 7220
04-21 10:50:35.090: E/AndroidRuntime(7220): java.lang.RuntimeException: Unable to resume activity
{com.google.android.apps.plus/com.google.android.apps.photos.phone.SetWallpaperActivity}:
java.lang.IllegalArgumentException: Image URI must be of the content scheme type
Here is the code that I use to let the user set the wallpaper:
String uriString = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
Uri u = Uri.parse(uriString);
Intent wall_intent = new Intent(Intent.ACTION_ATTACH_DATA);
wall_intent.setDataAndType(u, "image/*");
wall_intent.putExtra("mimeType", "image/*");
Intent chooserIntent = Intent.createChooser(wall_intent,
"Set As");
chooserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
context.startActivity(chooserIntent);
}
Where uriString is:
file:///storage/emulated/0/Pictures/Rockstar/image.jpg

I was able to figure it out. It was a combination of the code found here: Converting android image URI and scanning the media file after downloading.
So after the file finished downloading I get the path and do the following:
String uriString = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
//Update the System
Uri u = Uri.parse(uriString);
context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, u));
//Get the abs path using a file, this is important
File wallpaper_file = new File(u.getPath());
Uri contentURI = getImageContentUri(context, wallpaper_file.getAbsolutePath());
For some reason starting the media scanner, newing the file, and getting the absolute path are important, I'm not exactly sure why but I can't spend any more time on this!
The way to convert from a file URI to a content URI is as follows (taken from the linked StackOver flow post:
public static Uri getImageContentUri(Context context, String absPath) {
Log.v(TAG, "getImageContentUri: " + absPath);
Cursor cursor = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI
, new String[] { MediaStore.Images.Media._ID }
, MediaStore.Images.Media.DATA + "=? "
, new String[] { absPath }, null);
if (cursor != null && cursor.moveToFirst()) {
int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
return Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI , Integer.toString(id));
} else if (!absPath.isEmpty()) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, absPath);
return context.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
} else {
return null;
}
}
Maybe this will help someone in the future.

So my question is if anyone knows how to convert a full file path/URI (file://) into a content style URI (content://)?
Implement a ContentProvider. FileProvider offers an out-of-the-box solution for serving up local files.

I'm not sure about the technique you are using to set the wallpaper but the easiest way is probably to use WallpaperManager.setStream() which doesn't require any URI.
Also note that a file URI only works between apps if the file is publicly accessible so a content URI is a more general solution.
Using a content URI implies that a ContentProvider will serve the file. Which one depends on where your file is located.
If your app has a direct read access to the file, you can implement a content provider in your app by using for example the FileProvider class of the support library, but this should really only be used if the file is located in the private data storage of your app.
If the image is added to the system media gallery, you should probably use the URI provided by the MediaStore.

Android: resolving uri from content provider, fetching player avatar (Android Game services)

I'm stucked during the Game Services implementation in some of our games. I can't retrieve the user image (using Unity). I can get the Uri of the image (Uri from a content provider), but I cant use ImageManager because it stores the data in a imageView, and I want the url/path of the image to let Unity handle all the data.
My best try is setting a ContentResolver but I get a security error:
Permission Denial: opening provider com.google.android.gms.games.provider.GamesContentProvider
At this point I can't find any solution on that, in fact I'm not able to find anything related with GamesContentProvider at all. So I don't know where to find the right way to retrieve the data or find the permission.
Here you have part of the code:
public String getAvatarUrlGame(boolean highRes)
{
String n = "";
if (isSignedIn()) {
Uri uri;
if(highRes) uri = getGamesClient().getCurrentPlayer().getHiResImageUri();
else uri = getGamesClient().getCurrentPlayer().getIconImageUri();
if (uri != null)
{
Cursor cursor = this.getContentResolver().query(uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
n = cursor.getString(0);
cursor.close();
}
}
return n;
}
Any help will be apreciated. Thanks in advance!

The only way to access the images is via ImageManager. You can't use a content resolver. If you only want the images and don't want to handle ImageView's, you can use ImageManager.loadImage(OnImageLoadedListener, Uri), which will call your OnImageLoadedListener with a Drawable representing the image.
Then, to get a Unity-compatible bitmap from the Drawable, just convert it to a bitmap. For info on how to do this step, see this answer, particularly André's answer (the one that has the drawableToBitmap method).
Hope this helps!

Resolving the URI from different sources in Android while opening an image

My Android app opens images and makes manipulations on them. My Activity requests an image to be opened as follows:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Complete action using"),
PICK_FROM_FILE);
On doing this, it launches a dialog with three to four options, like the ES File Explorer: Files, Gallery, etc.
I wish to read this as a Bitmap using BitmapFactory.decodeFile(path).
When I choose the file from ES File Explorer, the path is computed like this:
String path = imageData.getData().getPath();
However, this does not work for choosing an image from the Gallery or Files, where the value of path is /external/images/media/38 for example.
So I put a check, to convert such a path that begins with external using:
if (path.startsWith("/external")) {
path = getFilePathFromUri(imageData.getData());
}
private String getFilePathFromUri(Uri uri) {
Cursor cursor = managedQuery(uri,
new String[] { MediaStore.Images.Media.DATA },
null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
This converts the above path to /mnt/sdcard/dcim/Camera/2011-11-13_15-33-24_304.jpg and now this works for BitmapFactory.decodeFile(path).
I understand that hardcoding such a check (/external) is not a good idea, is there a better, perhaps generic way to resolve the format of the URI returned in the Intent?

imageData.getData() returns a Uri. If its path starts with file:// (this is what most file managers will return), then the uri represents a file. Another option is uri represents a content item (this is what Gallery will return), in this case its path starts with content:// and you should call ContentProvider for an actual image file path (as you do in your sample). So I think you could go with something like this:
Uri uri = imageData.getData();
String scheme = uri.getScheme();
if ("file".equals(scheme)) {
// process as a uri that points to a file
} else if ("content".equals(scheme)) {
// process as a uri that points to a content item
}

You can ask MediaStore to create your Bitmap from the Uri:
Bitmap bmp = MediaStore.Images.Media.getBitmap( getContext().getContentResolver(), uri );

cover art on android

I am developing a sort of media player for android. The question is how can i get the cover art of audio file on android.
For example the default android media player shows album covers when listing albums, how can i get this artworks.

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);
ContentResolver res = context.getContentResolver();
InputStream in = res.openInputStream(uri);
Bitmap artwork = BitmapFactory.decodeStream(in);
More complete sample code can be found in Android Music player source here https://github.com/android/platform_packages_apps_music/blob/master/src/com/android/music/MusicUtils.java method getArtworkQuick.

You can use
MediaMetadataRetriever
class and get track info i.e. Title,Artist,Album,Image
Bitmap GetImage(String filepath) //filepath is path of music file
{
Bitmap image;
MediaMetadataRetriever mData=new MediaMetadataRetriever();
mData.setDataSource(filePath);
try{
byte art[]=mData.getEmbeddedPicture();
image=BitmapFactory.decodeByteArray(art, 0, art.length);
}
catch(Exception e)
{
image=null;
}
return image;
}

I don't know why everybody is making it so complicated you can use Glide to achieve this in simplest and efficient way with just 1 line of code
Declare this path in App Constants -
final public static Uri sArtworkUri = Uri
.parse("content://media/external/audio/albumart");
Get Image Uri using Album ID
Uri uri = ContentUris.withAppendedId(PlayerConstants.sArtworkUri,
listOfAlbums.get(position).getAlbumID());
Now simply display album art using uri :-
Glide.with(context).load(uri).placeholder(R.drawable.art_default).error(R.drawable.art_default)
.crossFade().centerCrop().into(holder.albumImage);
Glide will handle caching, scaling and lazy loading of images for you.
Hope it help somebody.

Here i can attach one function that is return album art from media store .
Here in function we just have to pass the album_id which we get from Media store .
public Bitmap getAlbumart(Long album_id)
{
Bitmap bm = null;
try
{
final Uri sArtworkUri = Uri
.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);
ParcelFileDescriptor pfd = context.getContentResolver()
.openFileDescriptor(uri, "r");
if (pfd != null)
{
FileDescriptor fd = pfd.getFileDescriptor();
bm = BitmapFactory.decodeFileDescriptor(fd);
}
} catch (Exception e) {
}
return bm;
}

Based on your comments to others, it seems like your question is less about Android and more about how to get album art in general. Perhaps this article on retrieving album art from Amazon will be helpful. Once you have a local copy and store it as Nick has suggested, I believe you should be able to retrieve it the way Fudgey suggested.

Android only recognizes files named "AlbumArt.jpg" as Album Covers. Just put the pictures with that name in the album folder and you'll be fine..

I don't know if you read that google is making Stackoverflow the official Android app development Q&A medium but for beginner questions... Now, I know nothing about developing in andriod, but a quick search of the Android Developers site, I found this:
MediaStore.Audio.AlbumColumns
Hopefully it'll help.
