POContentResolver.notifyChange() doesn't work

    <p>Some background information:</p> <p>When I run my application, a foreground activity displays cached information from my local SQLite database and meanwhile a background service connects to server and gets some fresh information. When data is retrieved, the service fires up my ContentProvider's insert method, to update my local SQLite database. When the insert is done, I notify my ContentObserver (foreground activity) about the change to refresh the view. </p> <p>I know the insert works fine, because when I rerun the application manually I can see new data on my screen. Unfortunately, auto refresh does not work. Calling the method <code>ContentObserver.notifyChange()</code> fails. The weirdest thing is that it doesn't even stop on the <code>catch (Exception e)</code> line. It goes straight outside the <code>try/catch</code> block. I have no idea what's going on. <a href="http://developer.android.com/guide/developing/debugging/debugging-log.html" rel="nofollow">LogCat</a>, and console are quiet.</p> <p>Here's the part of code from <code>insert</code> method within my ContentProvider responsible for insert and change notification.</p> <pre><code>SQLiteDatabase sqlDB = db.getWritableDatabase(); try { long newID = sqlDB.insertOrThrow(StatsCollectorDatabase.TABLE_USERS, null, values); if (newID &gt; 0) { Uri newUri = ContentUris.withAppendedId(uri, newID); ContentResolver contentResolver = getContext().getContentResolver(); contentResolver.notifyChange(uri, null); // This is the line that fails return newUri; } else { throw new SQLException("Failed to insert row into " + uri); } } catch (SQLiteConstraintException e) { Log.i(DEBUG_TAG, "Ignoring constraint failure."); } catch (Exception e) { Log.i(DEBUG_TAG, e.getLocalizedMessage()); } </code></pre> <p>Here's the code from <code>onCreate</code> method in foreground Activity:</p> <pre><code>Cursor cursor = this.managedQuery(StatsCollectorProvider.CONTENT_URI, null, null, null, null); String[] columns = new String[] { StatsCollectorDatabase._USER_NAME, StatsCollectorDatabase._USER_DEVICE_ID }; int[] views = new int[] { R.id.name_entry, R.id.number_entry }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this.getApplicationContext(), R.layout.list_item, cursor, columns, views, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER); this.setListAdapter(adapter); Intent intent = new Intent(this.getApplicationContext(), UsersDownloaderService.class); this.startService(intent); </code></pre> <p>I tried googling, but found nothing relevant. How do I fix this problem? </p> <p>I can provide more code if this'll be necessary.</p>

    1. COAre you using the same base URL for the `managedQuery` and the `notifyChange`? I have similar code which instantiates `SimpleCursorAdapter` without the flags, maybe you can try omitting the last argument...

    2. COThanks for the hint, but it wasn't it. Although, an upvote to you, kind sir, as you were the only one participating in my problem;)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
