    <p>I've got a <code>CursorLoader</code> in a <code>ListFragment</code> (that is inside a <code>ViewPager</code>) that queries a database. I have a content provider for that database, which I've verified works. </p> <p>The issue is this: when the app runs for the very first time a separate service calls a bulk <strong>insert</strong> in a <code>ContentProvider</code>:</p> <pre><code>public int bulkInsert(Uri uri, ContentValues[] values) { if(LOGV) Log.v(TAG, "insert(uri=" + uri + ", values" + values.toString() + ")"); final SQLiteDatabase db = openHelper.getWritableDatabase(); final int match = uriMatcher.match(uri); switch(match) { case SNAP: { db.beginTransaction(); for(ContentValues cv : values) { db.insertOrThrow(Tables.SNAP, null, cv); } db.setTransactionSuccessful(); db.endTransaction(); getContext().getApplicationContext().getContentResolver().notifyChange(uri, null); return values.length; } </code></pre> <p>The <code>CursorLoader</code> in the list fragment returns 0 rows though on the very first run (when the database gets created). If I close and restart the app then the <code>CursorLoader</code> works great and returns exactly what I need. I've tried to implement waiting via a handler, but it doesn't seem to help. Here is the <code>ListFragment</code> that utilizes the <code>CursorLoader</code>:</p> <pre><code>public class DataBySnapFragment extends ListFragment implements LoaderCallbacks&lt;Cursor&gt; { public static final String TAG = "DataBySnapFragment"; protected Cursor cursor = null; private DataBySnapAdapter adapter; private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); Log.d(TAG, "RELOADING!!!!!"); onLoadDelay(); } }; @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); Log.d(TAG, "onActivityCreated"); adapter = new DataBySnapAdapter(getActivity(), R.layout.list_item_databysnap, null, new String[]{}, new int[]{}, 0); setListAdapter(adapter); getLoaderManager().initLoader(0, null, this); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_databysnap, null); return view; } @Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("error_workaround_1", "workaroundforerror:Issue 19917, http://code.google.com/p/android/issues/detail?id=19917"); } @Override public Loader&lt;Cursor&gt; onCreateLoader(int id, Bundle args) { CursorLoader cursorLoader = new CursorLoader(getActivity(), Snap.CONTENT_URI, null, null, null, Snap.DATA_MONTH_TO_DATE + " DESC LIMIT 6"); return cursorLoader; } @Override public void onLoadFinished(Loader&lt;Cursor&gt; loader, Cursor data) { Log.d(TAG, "data rows: " + data.getCount()); if(data.getCount() &lt;= 0) { delayThread(); } else { adapter.swapCursor(data); } } @Override public void onLoaderReset(Loader&lt;Cursor&gt; loader) { adapter.swapCursor(null); } private void onLoadDelay() { getLoaderManager().initLoader(0, null, this); } private void delayThread() { new Thread() { public void run() { longTimeMethod(); handler.sendEmptyMessage(0); } }.start(); } private void longTimeMethod() { try { Thread.sleep(12000); } catch (InterruptedException e) { Log.e("tag", e.getMessage()); } } } </code></pre> <p>Can anyone let me know why this might be happening, or at least steer me in the right direction? Thanks!</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.

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).
