在我的 android 应用程序中，我有一个预定义的数据库（使用 sqlite 浏览器创建，它是 .db 格式），它位于 assets 文件夹中。用户应输入他/她的详细信息（姓名、出生日期、年龄、性别和血统）并单击保存按钮。当用户点击按钮输入的数据应该被插入到 sqlite 数据库中。但是单击保存按钮后，logcat 显示以下错误。

我的保存按钮代码段是：

case R.id.btnSave:
        personName = etName.getText().toString();
        date_of_birth = tvDOB.getText().toString();
        age = tvAge.getText().toString();

        int selected_rb_ID = genderGrp.getCheckedRadioButtonId();   
        RadioButton rb = (RadioButton) findViewById(selected_rb_ID);
        gender = rb.getText().toString();
        bloodGrp = spiBloodGrp.getSelectedItem().toString();
        String data = personName + date_of_birth + age + gender + bloodGrp;
        Toast.makeText(getApplicationContext(), data , Toast.LENGTH_SHORT).show();

        Person person = new Person();
        person.setName(personName);
        person.setDate_of_birth(date_of_birth);
        person.setAge(age);
        person.setGender(gender);
        person.setBloodGrp(bloodGrp);

        ContentValues values = new ContentValues();
        values.put(COLUMN_PERSON_NAME, person.getName());
        values.put(COLUMN_DOB, person.getDate_of_birth());
        values.put(COLUMN_AGE, person.getAge());
        values.put(COLUMN_GENDER, person.getGender());
        values.put(COLUMN_BLOODGRP, person.getBloodGrp());

        DBHelper dbHelper = new DBHelper(this);
        //dbHelper.createDataBase();
        dbHelper.openDataBase();
        if(dbHelper.insertIntoDatabase("EMPerson", values)){
            Toast.makeText(getApplicationContext(), "Data has been saved successfully", Toast.LENGTH_SHORT).show();
        }else{
            Toast.makeText(getApplicationContext(), "Oops ! Try again", Toast.LENGTH_SHORT).show();
        }
        dbHelper.closeDatabase();

        break;

我的 DBhelper 类有一个名为 insertIntoDatabase 的方法。

public boolean insertIntoDatabase(String table, ContentValues cv) {
    try {
        myDatabase.insert(table, null, cv);
        Log.d("INSERT", "Information Saved");
        return true;
    } catch (Exception e) {
        // TODO Auto-generated catch block
        Log.d("INSERT", e.toString());
        return false;
    }
}

谁能解释一下发生了什么，我该如何解决这个问题？

谢谢
