8 years ago We really need more context. Google says this can happen if there are open cursors, but we know nothing about what the app is doing when it crashes. On Nov 2, 2015 11:06 AM, "Gray" notifications@github.com wrote:

8 years ago By context I mean what is your app doing. Need to see some code and possibly how you're making calls. My rough guess is you're either closing your SQliteOpenHelper, or since you've got a lazy foreign collection, you're making too many cursors and blowing up something. It would seem each entry in the adapter is making a lazy call.

8 years ago I am using fabric for tracking crash. I got same exception. When i try to run "contentsDao.queryForAll();"
My code : private Dao<L_Content, Integer> contentsDao; . . . . public List getAllContents(String searchQuery) { try { if (searchQuery == null) { return contentsDao.queryForAll(); } else { if (contentsQuery == null) { contentsQuery= makeContentsQuery(false); } String nameParameter = searchQuery == null ? "%%" : "%"+searchQuery.trim()+"%"; contentsQuery.setArgumentHolderValue(0,nameParameter); return contentsDao.query(contentsQuery); } } catch (SQLException e){ e.printStackTrace(); return null; } } . . . .
Logcat output :

8 years ago Different things can cause the issue, but the summary is it tried to allocate 2M for the cursor window and failed. I've recently become very familiar with this part of the api. It can fail because you're out of memory, but I would imagine other situations. Its not an ormlite thing, though. Its deep android. More code context would be helpful. Probably better to post to stackoverflow, though.
I would make sure the connection hasn't been closed for some reason. It looks like its a field on that object. If you're opening/closing your db but caching the dao, I think you can run into problems.
Also, not to nitpick, but the first part of this statement can be removed:
String nameParameter = searchQuery == null ? "%%" : "%"+searchQuery.trim()+"%";
If searchQuery is null, you've already returned from the method.

8 years ago @kpgalligan thanks for your attention. Second "searchQuery == null" if clause is unnecessary. I will remove this line.
This method is used thousands times a day. But this exception occured once time. Maybe its a android or memory bug. I will open an issue on stackoverflow.

8 years ago Not sure it'll help, but I've seen this recently myself, but in a wildly different context.
Each Cursor has a CursorWindow, which is where the raw data is copied. Each CursorWindow gets 2M. If you have a lot of open Cursor objects, you can pretty quickly rack up memory usage. You could in theory do this with a deep eager fetch, as each runs a query, but by default Ormlite doesn't really go very deep before a killswitch stops (again, by default).
Its probably something else, though.

8 years ago Also, not sure what this is for, but in general if you get an exception once and its not repeatable, I wouldn't lose a whole lot of sleep over it. Depends on the app, though, I guess.

5 years ago @erSAurabhSA, By observing the stack trace, it is failed to allocate memory while instantiating the CursorWindow object. I think, it is OOM. As you are able to reproduce this every time, profile your memory usage in Android Studio and check for hotspots in your application.
