我收到一份崩溃报告，在我调用startManagingCursor时说出OutOfMemoryError。这是返回的堆栈跟踪：
java.lang.OutOfMemoryError

我非常小心地关闭我的游标，SQLiteDatabase和SQLiteOpenHelper。以下是崩溃引用的短代码段：
Cursor callCursor = lockLib.getCallState();
startManagingCursor(callCursor);
....
callCursor.close();
非常难过如何解决此问题。我知道startManagingCursor已经折旧，但我不是针对HONEYCOMB或更高版本，所以我无法切换到CursorLoader。有没有人对如何进行有任何建议？
