android-cursor

In my app I work with ContentProvider and use LoaderManager.LoaderCallbacks<Cursor>. Fragment (View) public class ArticleCatalogFragment extends BaseFragment implements ArticleCatalogPresenter.View, LoaderManager.LoaderCallbacks<Cursor> { @Override public Loader<Cursor> onCreateLoader(int id, Bundle args) { return onCreateArticleCatalogLoader(args); } @Override public void onLoadFinished(Loader<Cursor> loader, Cursor data) { data.registerContentObserver(new LoaderContentObserver(new Handler(), loader)); updateUI(data); } private Loader onCreateArticleCatalogLoader(Bundle args) { int categoryId

As the title says, when trying to paginate a ListView backed by a SimpleCursorAdapter and a CursorLoader , old cursors are getting closed, thus the below exception is being thrown. The first 2 pages load just fine (the first isn't using the MergeCursor and the second page is the first one to use the MergeCursor ). I don't call any close() on any cursor whatsoever. What is interesting is that while debugging, I cannot see the closed flags on any cursor being set as true, for what it's worth. Might be an issue with the MergeCursor then. Let me know if you guys have any solutions, I'm out of

I have to execute a query and store the result in a list, the function that I use is this follow : List<SpoolInDB> getSpoolInRecords(String label, boolean getLastInserted) { List<SpoolInDB> spoolInList = new ArrayList<>(); try { if (mdb == null) mdb = mdbHelper.getWritableDatabase(); SQLiteQueryBuilder qb = new SQLiteQueryBuilder(); qb.setTables(TABLE_SPOOLIN); Cursor c = qb.query(mdb, null, " label='" + label + "'", null, null, null, " dateins " + (getLastInserted ? "desc" : "asc")); if (c != null) { c.moveToFirst(); if (c.getCount() > 0) { int ndxid = c.getColumnIndex("id"); int ndxserverID

i want to select unique contacts from android only that contacts which have phone numbers. i am using this code ContentResolver cr = getContentResolver(); Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, ContactsContract.Contacts.DISPLAY_NAME); // Find the ListView resource. mainListView = (ListView) findViewById(R.id.mainListView); // When item is tapped, toggle checked properties of CheckBox and // Planet. mainListView .setOnItemClickListener(new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View item, int position, long id)

Consider the scenario as in this picture: Three photos, one of them is a large GIF file (3MP). I'm querying MediaStore in order to retrieve the correspondent thumbnails. If I initialize the Cursor via CursorLoader with this sortOrder: MediaStore.Images.Media.DATE_ADDED + " DESC"" What happens: MediaStore returns the previous successfully retrieved thumbnail: Expected behaviour: when MediaStore cannot retrieve the thumbnail of a given image for some reason it has to return NULL, as per its Javadoc: "... Returns A Bitmap instance. It could be null if the original image associated with origId

I'm using a SimpleCursorAdapter to display results in a ListView but since I've got to query my database lots of times during a search (using the SearchView widget) it worries me that the cursor might be left opened. This is how I query my database and show the results in a ListView: class SearchCustomers extends AsyncTask<String,Void,Cursor>{ @Override protected Cursor doInBackground(String... params) { //get the query String query=params[0].toLowerCase(Locale.getDefault()); Cursor cursor=mDB.searchCustomersByName((query != null ? query : "@@@@")); return cursor; } @Override protected void

I have strange problem with android database and cursors. Time to time (very rarely) happens, that I got crash report from customers. It's hard to find out why it crashes, as I have ~ 150 000 active users and maybe 1 report per week or so, so it's really some minor bug. Here is exception: STACK_TRACE=java.lang.IllegalStateException: Cannot perform this operation because the connection pool has been closed. at android.database.sqlite.SQLiteConnectionPool.throwIfClosedLocked(SQLiteConnectionPool.java:962) at android.database.sqlite.SQLiteConnectionPool.waitForConnection(SQLiteConnectionPool.java
