我收到一个崩溃报告，说我在调用startManagingCursor时OutOfMemoryError。这里是返回的堆栈跟踪：Android OutOfMemoryError startManagingCursor中的崩溃

我非常小心地关闭我的游标，SQLiteDatabase和SQLiteOpenHelper。这是一个短代码段，崩溃是指：
Cursor callCursor = lockLib.getCallState();
startManagingCursor(callCursor);
....
callCursor.close();
对如何去解决这个问题很难。我知道startManagingCursor是贬值的，但我不是针对HONEYCOMB或更高版本，所以我不能切换到CursorLoader。有没有人有任何建议如何进行？
