android 上的 H2 数据库内存不足错误？
H2 Database OutOfMemoryError on android?
我正在尝试在 android 上为我的应用程序使用 H2，其中一个主要 table 是：
CREATE TABLE IF NOT EXISTS "
+ "tbl_content("
+ "date DATE PRIMARY KEY, "
+ "content OTHER);
当我向其中添加数据时，向其中插入一些数据后 table 我收到以下错误：
我更改了我的代码很多次（更改读取文件，我也拆分了我的文件等等......）但没有任何改变，每次我一次又一次地得到这个错误：java.lang.OutOfMemoryError: Capacity:
我也将 android:largeHeap="true" 添加到清单文件，但没有任何变化！！！

这不是 H2 问题，这个错误来自应用程序的其他部分，因为堆大小很小，我尝试读取大块文件并将其插入数据库，我更改了读取文件的程序逻辑一切都很完美。
