Resolves an Android "content://" URI to an actual image file in the gallery

ContentURIResolve.java

// And to convert the image URI (content:// format) to the direct file system path of the image file
// From "http://www.androidsnippets.com/get-file-path-of-gallery-image"
public String getRealPathFromURI(Uri contentUri) {

        // can post image
        String [] proj={MediaStore.Images.Media.DATA};
        Cursor cursor = managedQuery( contentUri,
                        proj, // Which columns to return
                        null, // WHERE clause; which rows to return (all rows)
                        null, // WHERE clause selection arguments (none)
                        null); // Order-by clause (ascending by name)
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();

        return cursor.getString(column_index);
}

I checked this code but I am not able to convert content:// to file"//
