我正在使用此library进行数据库操作。我遇到了一个例外。当我试图跑 “contentsDao.queryForAll（）;”，我得到了“2048 kb的光标窗口分配失败”。异常。
我的代码：
private Dao contentsDao = getDao(L_Content.class);
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输出：
