因此，我正在尝试从 android内部私有存储中加载预存储的 XML 文件并将其解析为 JDOM 文档。XML 与以下内容相同；
<?xml version="1.0" encoding="UTF-8"?>
<data_store>
<employee_table id="" fullname="" username="" password=""/>
<periodical_table id="" ref="" siteid="" siteaddress="" sitenotes="" clientid="" clientaddress="" clientnotes="" scheduled="" />
<hazard />
<compliance />
<additional siteid="" type="" value=""/>
<notification_table id="" value="" employeeid="" viewed="false"/>
</data_store>
并使用以下代码存储；
SAXBuilder builder = new SAXBuilder();
doc = builder.build(ThisApplication.resources().openRawResource(R.raw.default_store));
FileOutputStream fos = ThisApplication.mApp.openFileOutput("data_store.xml", Context.MODE_PRIVATE);
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(doc);
oos.close();
本例中的解析工作正常。所以我知道 XML 是有效的。我在这里所做的只是将上述 XML 保存到私有存储中。但是，稍后，当我尝试使用以下命令从内部存储中读取该文件时；
SAXBuilder builder = new SAXBuilder();
FileInputStream fis = ThisApplication.mApp.openFileInput("data_store.xml");
doc = builder.build(fis); // This is line 28 in the log, where the exception is thrown
fis.close();
我从中得到以下日志builder.build(fis);

有些人建议定义一个字符集可以解决这个问题，但我不能这样做，因为必须使用openFileInput(). 否则，将无法访问安全存储在内部存储中的文件。
我确定我在这里误解了一些东西。如果有人使用 JDOM 成功访问并解析了内部存储文件，我可以使用他们的输入（不是双关语）。
