Could not allocate CursorWindow

Question

I\'m operating on an SQLite3 database in my android app. I just read from the pre populated database that has 200k rows and 14 columns. Entries are words. Datatype

Answer 1

Error -12 means cursor leak. Pls try close it as follow:

try {....} finally {  cursor.close();}

Answer 2

I was quering in a loop. And closing the cursor inside the loop and not outside solved the problem.

Answer 3

Android cursors read all the query results into memory, and have a limit of 1 MB for that data.

This limit was chosen because this amount of data is likely to make your app run sluggishly on a mobile device.

You should, if possible:

• do the computations not in your code but in SQL;
• query only the data that you need (i.e., do not use SELECT * but get only the columns you need, and use a WHERE filter);
• read the data in smaller portions.
