image - Get content uri from file path in android


Translate

I know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file ?

Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

    Try with:

    ImageView.setImageURI(Uri.fromFile(new File("/sdcard/cats.jpg")));
    

    Or with:

    ImageView.setImageURI(Uri.parse(new File("/sdcard/cats.jpg").toString()));

    UPDATE

    Here it is assumed that your media (Image/Video) is already added to content media provider. If not then you will not able to get the content URL as exact what you want. Instead there will be file Uri.

    I had same question for my file explorer activity. You should know that the contenturi for file only supports mediastore data like image, audio and video. I am giving you the code for getting image content uri from selecting an image from sdcard. Try this code, maybe it will work for you...

    public static Uri getImageContentUri(Context context, File imageFile) {
      String filePath = imageFile.getAbsolutePath();
      Cursor cursor = context.getContentResolver().query(
          MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
          new String[] { MediaStore.Images.Media._ID },
          MediaStore.Images.Media.DATA + "=? ",
          new String[] { filePath }, null);
      if (cursor != null && cursor.moveToFirst()) {
        int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
        cursor.close();
        return Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + id);
      } else {
        if (imageFile.exists()) {
          ContentValues values = new ContentValues();
          values.put(MediaStore.Images.Media.DATA, filePath);
          return context.getContentResolver().insert(
              MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        } else {
          return null;
        }
      }
    }

    // This code works for images on 2.2, not sure if any other media types

       //Your file path - Example here is "/sdcard/cats.jpg"
       final String filePathThis = imagePaths.get(position).toString();
    
       MediaScannerConnectionClient mediaScannerClient = new
       MediaScannerConnectionClient() {
        private MediaScannerConnection msc = null;
        {
            msc = new MediaScannerConnection(getApplicationContext(), this);
            msc.connect();
        }
    
        public void onMediaScannerConnected(){
            msc.scanFile(filePathThis, null);
        }
    
    
        public void onScanCompleted(String path, Uri uri) {
            //This is where you get your content uri
                Log.d(TAG, uri.toString());
            msc.disconnect();
        }
       };

    The accepted solution is probably the best bet for your purposes, but to actually answer the question in the subject line:

    In my app, I have to get the path from URIs and get the URI from paths. The former:

    /**
     * Gets the corresponding path to a file from the given content:// URI
     * @param selectedVideoUri The content:// URI to find the file path from
     * @param contentResolver The content resolver to use to perform the query.
     * @return the file path as a string
     */
    private String getFilePathFromContentUri(Uri selectedVideoUri,
            ContentResolver contentResolver) {
        String filePath;
        String[] filePathColumn = {MediaColumns.DATA};
    
        Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);
        cursor.moveToFirst();
    
        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        filePath = cursor.getString(columnIndex);
        cursor.close();
        return filePath;
    }
    

    The latter (which I do for videos, but can also be used for Audio or Files or other types of stored content by substituting MediaStore.Audio (etc) for MediaStore.Video):

    /**
     * Gets the MediaStore video ID of a given file on external storage
     * @param filePath The path (on external storage) of the file to resolve the ID of
     * @param contentResolver The content resolver to use to perform the query.
     * @return the video ID as a long
     */
    private long getVideoIdFromFilePath(String filePath,
            ContentResolver contentResolver) {
    
    
        long videoId;
        Log.d(TAG,"Loading file " + filePath);
    
                // This returns us content://media/external/videos/media (or something like that)
                // I pass in "external" because that's the MediaStore's name for the external
                // storage on my device (the other possibility is "internal")
        Uri videosUri = MediaStore.Video.Media.getContentUri("external");
    
        Log.d(TAG,"videosUri = " + videosUri.toString());
    
        String[] projection = {MediaStore.Video.VideoColumns._ID};
    
        // TODO This will break if we have no matching item in the MediaStore.
        Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null);
        cursor.moveToFirst();
    
        int columnIndex = cursor.getColumnIndex(projection[0]);
        videoId = cursor.getLong(columnIndex);
    
        Log.d(TAG,"Video ID is " + videoId);
        cursor.close();
        return videoId;
    }
    

    Basically, the DATA column of MediaStore (or whichever sub-section of it you're querying) stores the file path, so you use that info to look it up.

    You can use these two ways based on use

    Uri uri = Uri.parse("String file location");

    or

    Uri uri = Uri.fromFile(new File("string file location"));

    I have tried both ways and both works.

    Easiest and the robust way for creating Content Uri content:// from a File is to use FileProvider. Uri provided by FileProvider can be used also providing Uri for sharing files with other apps too. To get File Uri from a absolute path of File you can use DocumentFile.fromFile(new File(path, name)), it's added in Api 22, and returns null for versions below.

    File imagePath = new File(Context.getFilesDir(), "images");
    File newFile = new File(imagePath, "default_image.jpg");
    Uri contentUri = getUriForFile(getContext(), "com.mydomain.fileprovider", newFile);

    Obtaining the File ID without writing any code, just with adb shell CLI commands:

    adb shell content query --uri "content://media/external/video/media" | grep FILE_NAME | grep -Eo " _id=([0-9]+)," | grep -Eo "[0-9]+"

    Its late, but may help someone in future.

    To get content URI for a file, you may use the following method:

    FileProvider.getUriForFile(Context context, String authority, File file)

    It returns the content URI.

    U can try below code snippet

        public Uri getUri(ContentResolver cr, String path){
        Uri mediaUri = MediaStore.Files.getContentUri(VOLUME_NAME);
        Cursor ca = cr.query(mediaUri, new String[] { MediaStore.MediaColumns._ID }, MediaStore.MediaColumns.DATA + "=?", new String[] {path}, null);
        if (ca != null && ca.moveToFirst()) {
            int id = ca.getInt(ca.getColumnIndex(MediaStore.MediaColumns._ID));
            ca.close();
            return  MediaStore.Files.getContentUri(VOLUME_NAME,id);
        }
        if(ca != null) {
            ca.close();
        }
        return null;
    }
