无法读取Android资产中的数据库

Question

我有一个名为HOSPITALS.db的数据库，有97个条目和8个列。 I tried following this。

但它产生了错误

  

java.lang.RuntimeException：无法启动活动ComponentInfo {com.example.mariel.paths / com.example.mariel.paths.MainActivity}：android.database.sqlite.SQLiteException：no such table：hospitalList（code 1 ）:,同时编译：SELECT * FROM hospitalList

TableB

Hospitals.java

dbHelper = new DataBaseHelper(this);
    dbHelper.openDataBase();
    hosp = new Hospitals();
    hosp = dbHelper.Get_ContactDetails();

    ArrayList<OverlayItem> anotherOverlayItemArray = new ArrayList<>();

    for (int i = 0; i < hosp.getHospName().size(); i++){
        anotherOverlayItemArray.add(new OverlayItem("Road", "Nodes", new GeoPoint(hosp.getLatitude().get(i), hosp.getLongitude().get(i))));
    }

    ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay
            = new ItemizedIconOverlay<>(
            this, anotherOverlayItemArray, null);
    map.getOverlays().add(anotherItemizedIconOverlay);
    dbHelper.close();

DataBaseHelper.java

public class Hospitals {
    public List<String> hosp_name = new ArrayList<>();
    public List<Double> longitude = new ArrayList<>();
    public List<Double> latitude = new ArrayList<>();

    public List<String> getHospName() {
        return hosp_name;
    }

    public void setName(List<String> hosp_name) {
        this.hosp_name = hosp_name;
    }

    public List<Double> getLatitude() {
        return latitude;
    }

    public void setLatitude(List<Double> latitude){
        this.latitude = latitude;
    }

    public List<Double> getLongitude() {
        return longitude;
    }

    public void setLongitude() {
        this.longitude = longitude;
    }

    // constructor
    public Hospitals (List<String> hosp_name, List<Double> latitude, List<Double> longitude){
        this.hosp_name = hosp_name;
        this.latitude = latitude;

    public Hospitals (){
