Problem, "My application has stopped" - "SQLiteException: no such table"

I have created an App to consult the address of a person by placing its name in an EditText, for the database I used the BD Browser program for SQlite, create a folder called assets and place the .db file there. The application opens in the emulator, but by pressing the button to search I get the error "Unfortunaly, My application has stopped" and it closes. Thanks for any help

Other information: The emulator is Genymotion, use a generic device 5.0.0 API 21.

The logcat errors are the following:

The Codes are as follows:

MainActivity.java:

package com.example.propietario.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

public EditText name;
public Button query_button;
public TextView result_address;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    name=findViewById(R.id.name);
    query_button=findViewById(R.id.query_button);
    result_address=findViewById(R.id.result);

    //onclicklistener
    query_button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //instance of database access

            DataBaseAccess dataBaseAccess=DataBaseAccess.getInstance(getApplicationContext());
            dataBaseAccess.open();

            //getting string

            String n=name.getText().toString();
            String address = dataBaseAccess.getAddress(n);


            //set to textview

            result_address.setText(address);

            dataBaseAccess.close();

            //database conection closed

        }
    });
}
}

DatabaseOpenHelper.java:

package com.example.propietario.myapplication;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DataBaseOpenHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME="MyExternalDatabase.db";
private static final int  DATABASE_VERSION=1;

//constructor

public DataBaseOpenHelper(Context context){
    super(context, DATABASE_NAME, null, DATABASE_VERSION);

}

@Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {

}

@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {

}
}

DataBaseAccess.java:

package com.example.propietario.myapplication;

import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DataBaseAccess {
private SQLiteOpenHelper openHelper;
private SQLiteDatabase db;
private static DataBaseAccess instance;
Cursor c = null;

//private constructor

private DataBaseAccess(Context context){
    this.openHelper=new DataBaseOpenHelper(context);

}

//to return
public static DataBaseAccess getInstance(Context context){
    if (instance==null){
        instance=new DataBaseAccess(context);

    }
    return instance;
}

//to open database

public void open(){
    this.db=openHelper.getWritableDatabase();

}

//close database conetcion

public void close(){
    if(db!=null){
        this.db.close();
    }
}

//method to query

public String getAddress(String name){
    c=db.rawQuery("Select Address from Table1 where Name ='"+name+"'", new String[]{});
    StringBuffer buffer = new StringBuffer();
    while(c.moveToNext()){
        String address = c.getString(0);
        buffer.append(""+address);
    }
    return buffer.toString();
}

}

Add the lines you indicated, but I'm not sure if I added them correctly because it still does not work, these are the codes:

DatabaseOpenHelper.java:

package com.example.diego.databasetest2;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;

import com.readystatesoftware.sqliteasset.SQLiteAssetHelper;


public class DatabaseOpenHelper extends SQLiteAssetHelper {
private static final String 
DATABASE_NAME="MyExternaldatabase.db";
private static final int DATABASE_VERSION=1;

public void onCreate(SQLiteDatabase sqLiteDatabase){
    sqLiteDatabase.execSQL(DataBase.CREATE_TABLE);
}

//constructor

public DatabaseOpenHelper(Context context){
    super(context, DATABASE_NAME,null, DATABASE_VERSION);

}


}

In order to create and call the database, should I create another class?
