Android ContentProvider calls bursts of setNotificationUri() to CursorAdapter when many rows are inserted with a batch operation

Question

I have a custom ContentProvider which manages the access to a SQLite database. To load the content of a database table in a ListFragment, I use the

I found a simpler solution that I discovered from Google's I/O app. You just have to override the applyBatch method in your ContentProvider and perform all the operations in a transaction. Notifications are not sent until the transaction commits, which results in minimizing the number of ContentProvider change-notifications that are sent out:

@Override
public ContentProviderResult[] applyBatch(ArrayList operations)
        throws OperationApplicationException {

    final SQLiteDatabase db = dbOpenHelper.getWritableDatabase();
    db.beginTransaction();
    try {
        final int numOperations = operations.size();
        final ContentProviderResult[] results = new ContentProviderResult[numOperations];
        for (int i = 0; i < numOperations; i++) {
            results[i] = operations.get(i).apply(this, results, i);
        }
        db.setTransactionSuccessful();
        return results;
    } finally {
        db.endTransaction();
    }
}
