package com.example.dbtest2;

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

public class DataBaseHelper extends SQLiteOpenHelper {
    public static String DATABASE_NAME="riyas.db";
    public static int DATABASE_VERSION=1;



    //table login
    public static String TABLE_NAME1="login";

    public static String COL_L1="ID";
    public static String COL_L2="USERNAME";
    public static String COL_L3="PASSWORD";

    //table record
    public static String TABLE_NAME2="record";

    public static String COL_R1="ID";
    public static String COL_R2="NAME";
    public static String COL_R3="ADDRESS";
    public static String COL_R4="MOBILE";
    public static String COL_R5="MALE";
    public static String COL_R6="FEMALE";
    public static String COL_R7="DOC_NAME";
    public static String COL_R8="CHECK1";
    public static String COL_R9="CHECK2";

    public static String mytab1="create table"+TABLE_NAME1+" ("
            +COL_L1 +" INTEGER PRIMARY KEY AUTOINCREMENT,NOT NULL,"
            +COL_L2 +"TEXT,NOT NULL,"
            +COL_L3+ "TEXT,NOT NULL,"
            +");";


     public static String mytab2="create table"+TABLE_NAME2+" ("
            + COL_R1+ "INTEGER PRIMARY KEY AUTOINCREMENT,NOT NULL,"
            + COL_R2 +"TEXT,"
             +COL_R3+ "TEXT,"
             +COL_R4 +"INTEGER,"

            + COL_R8+"TEXT,"
            + COL_R9 +"TEXT,"
              +");";

    public DataBaseHelper(Context context) {
        super(context, DATABASE_NAME, null, 1);
        // TODO Auto-generated constructor stub
        SQLiteDatabase Cdb=this.getWritableDatabase();
    }

    @Override
    public void onCreate(SQLiteDatabase Cdb) {
        // TODO Auto-generated method stub
        Cdb.execSQL(mytab1);
       Cdb.execSQL(mytab2);
               }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // TODO Auto-generated method stub
    db.execSQL("DROP TABLE IF EXIST"+TABLE_NAME1);
    db.execSQL("DROP TABLE IF EXIST"+TABLE_NAME2);

    onCreate(db);
    }
}

my main activity is...

package com.example.dbtest2;

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

public class MainActivity extends ActionBarActivity {
    DataBaseHelper mydb;

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

    }
}

logcat result is....

At first look, it seems to be your table definitions (too many commas in the wrong place), try changing to:

public static String mytab1="create table"+TABLE_NAME1+" ("
        +COL_L1 +" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,"
        +COL_L2 +" TEXT NOT NULL,"
        +COL_L3+ " TEXT NOT NULL"
        +");";


 public static String mytab2="create table"+TABLE_NAME2+" ("
        + COL_R1+ "INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,"
        + COL_R2 +" TEXT,"
         +COL_R3+ " TEXT,"
         +COL_R4 +" INTEGER,"
         +COL_R5 +" TEXT,"
         +COL_R6 +" TEXT,"
        + COL_R7 +" TEXT,"
        + COL_R8+" TEXT,"
        + COL_R9 +" TEXT"
          +");";

also there is no space between your variable names and the data type. LogCat is letting you know there are syntax errors.

Your table creation are both wrong:
You put some unneeded commas and didn't provide some required spaces, as well.

These are the correct ones

public static String mytab1 = "CREATE TABLE " + TABLE_NAME1 + " ("
    + COL_L1 + " INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,"
    + COL_L2 + " TEXT NOT NULL,"
    + COL_L3 + " TEXT NOT NULL)";

public static String mytab2 = "CREATE TABLE " + TABLE_NAME2 + " ("
    + COL_R1 + " INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,"
    + COL_R2 + " TEXT,"
    + COL_R3 + " TEXT,"
    + COL_R4 + " INTEGER,"
    + COL_R5 + " TEXT,"
    + COL_R6 + " TEXT,"
    + COL_R7 + " TEXT,"
    + COL_R8 + " TEXT,"
    + COL_R9 + " TEXT)";
