    <p>Basically i have image path that looks like this: /mnt/sdcard/Pictures/image.jpg And i need to get a path to thumbnail from it, in a fastest possible way.</p> <p>I am trying to use MediaStore.Images.Thumbnails.queryMiniThumbnail, but no matter what i pass i get null cursor. Thanks!</p> <p><strong>EDIT:</strong> This is the function that brings ALL of the image paths and thumbnail paths and stores them in a String. What I need is a function that returns thumbnail path for a specific image path (/mnt/sdcard/Pictures/image.jpg). Thanks</p> <pre><code>public String getThumbPaths(ThumbContext ctx) { Uri uri = MediaStore.Images.Thumbnails.getContentUri("external"); Cursor cursor = MediaStore.Images.Thumbnails.queryMiniThumbnails(ctx .getActivity().getContentResolver(), uri, MediaStore.Images.Thumbnails.MINI_KIND, null); int columnIndex = cursor.getColumnIndex(Thumbnails.IMAGE_ID); String[] filePathColumn = { MediaStore.Images.Media.DATA }; StringBuilder stringBuilder = new StringBuilder(); String id = MediaStore.Images.Media._ID + "=?"; String orientation="1"; for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) { String imageId = cursor.getString(columnIndex); Cursor images = ctx.getActivity().managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, filePathColumn, id, new String[] { imageId }, null); String filePath = ""; if (images != null &amp;&amp; images.moveToFirst()) { filePath = images.getString(images .getColumnIndex(filePathColumn[0])); } ExifInterface exifReader; try { exifReader = new ExifInterface(filePath); orientation=exifReader.getAttribute(ExifInterface.TAG_ORIENTATION); } catch (IOException e) { // TODO Auto-generated catch block //e.printStackTrace(); } stringBuilder.append(cursor.getString(1) + ";"); stringBuilder.append(filePath + ";"); stringBuilder.append(orientation + ";"); orientation="1"; } //cursor.close(); return stringBuilder.toString(); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
