Hello I try to develop one application based on the SQLiteDatabase. I develop simple code which create database but it's not working in AVD means its crash the application. Please guys help me out.

I post my code and error for that. It is very appreciable.

DatabaseHelper.java

package com.example.bhaumik.sqlitedatabasetest;

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

/**
 * Created by Bhaumik on 25-02-2016.
 */
public class DatabaseHelper extends SQLiteOpenHelper {

    public static final String DATABASE_NAME = "Student.db";
    public static final String TABLE_NAME = "student";
    public static final String COLUMN_1 = "ID";
    public static final String COLUMN_2 = "NAME";
    public static final String COLUMN_3 = "SURNAME";



    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, 1);
        SQLiteDatabase db = this.getWritableDatabase();
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("create table" + TABLE_NAME + "(ID INTEGER PRIMARY KEY AUTOINCREMENT)");
        //db.execSQL("create table " + TABLE_NAME +
            //    " (ID INTEGER AUTOINCREMENT , PRODUCT_NAME PRIMARY KEY TEXT , PRODUCT_SIZE INTEGER , PRODUCT_RUPPESS INTEGER , BUY_NUMBER INTEGER)");



    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

        db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
        onCreate(db);
    }
}

MainActivity.java

package com.example.bhaumik.sqlitedatabasetest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
    DatabaseHelper mydb ;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mydb = new DatabaseHelper(this);

    }
}
