    <p>To answer the question in the title:</p> <p>I have to get the path from URIs and get the URI from paths in my app. The former:</p> <pre><code>/** * 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; } </code></pre> <p>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):</p> <pre><code>/** * 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; } </code></pre> <p>Basically, the <code>DATA</code> column of <code>MediaStore</code> (or whichever sub-section of it you're querying) stores the file path, so you use that info to look it up.</p>

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.
