public class GreenSQLiteHelper extends SQLiteOpenHelper {

private static final String DB_NAME = "greencampus.db";
private static final int DB_VERSION = 2;

//table USER
public static final String USER_TABLE = "USER";
public static final String COLLUMN_USERNAME = "USERNAME";
public static final String COLLUMN_PASSWORD = "PASWORD";
public static final String COLLUMN_NOREK=  "NOREK";
public static final String COLLUMN_EMAIL = "EMAIL";
public static final String CREATE_USER =
        "CREATE TABLE" + USER_TABLE + "("
                + COLLUMN_NOREK + "TEXT PRIMARY KEY,"
        +COLLUMN_USERNAME + "TEXT,"
        + COLLUMN_PASSWORD + "TEXT,"
        + COLLUMN_EMAIL + "TEXT)";

//table tapcash
public static final String TAPCASH_TABLE = "TAPCASH";
public static final String COLLUMN_FNAME = "FNAME";
public static final String COLLUMN_LNAME = "LNAME";
public static final String COLLUMN_SALDOT = "SALDOT";
public static final String COLLUMN_SALDOR = "SALDOR";
public static final String FOREIGN_KEY_NOREK = "USER_NOREK";
public static final String CREATE_TAPCASH =
    "CREATE TABLE" + TAPCASH_TABLE +"("
            + BaseColumns._ID + "INTEGER PRIMARY KEY AUTOINCREMENT," +
            COLLUMN_SALDOT + "TEXT, " +
            COLLUMN_SALDOR + "TEXT, " +
            COLLUMN_FNAME + "TEXT, " +
            COLLUMN_LNAME + "TEXT, " +
            FOREIGN_KEY_NOREK + "TEXT, " +
            "FOREIGN KEY(" + FOREIGN_KEY_NOREK + ") REFERENCES USER(NOREK)";


//table bus
public static final String BUS_TABLE = "BUS";
public static final String COLLUMN_NOBUS = "NOBUS";
public static final String COLLUMN_JADWAL = "JADWAL";
public static final String FOREIGN_KEY_SHELTER ="SHELTER_ID";
public static final String CREATE_BUS =
"CREATE TABLE" + BUS_TABLE + "("
        + BaseColumns._ID + "INTEGER PRIMARY KEY AUTOINCREMENT," +
        COLLUMN_NOBUS + "TEXT, " +
        COLLUMN_JADWAL + "TEXT, " +
        FOREIGN_KEY_SHELTER + "INTEGER, " +
        "FOREIGN KEY(" + FOREIGN_KEY_SHELTER + ") REFERENCES SHELTER(_ID)";

//table shelter
public static final String SHELTER_TABLE = "SHELTER";
public static final String COLLUMN_NAMAS = "NAMA";
public static final String COLLUMN_KOORDINATS = "KOORDINAT";
public static final String CREATE_SHELTER =
    "CREATE TABLE" + SHELTER_TABLE + "("
            + BaseColumns._ID + "INTEGER PRIMARY KEY AUTOINCREMENT," +
    COLLUMN_NAMAS + "TEXT, " +
    COLLUMN_KOORDINATS + "TEXT) ";

//table map
public static final String MAP_TABLE = "MAP";
public static final String COLLUMN_NAMAM = "NAMA MAP";
public static final String COLLUMN_KOORDINATM = "KOORDINAT";
public static final String CREATE_MAP =
    "CREATE TABLE" + MAP_TABLE + "("
            + BaseColumns._ID + "INTEGER PRIMARY KEY AUTOINCREMENT," +
    COLLUMN_NAMAM + "TEXT, " +
    COLLUMN_KOORDINATM + "TEXT) ";

public GreenSQLiteHelper(Context context){
    super(context, DB_NAME, null, DB_VERSION );
    SQLiteDatabase db = this.getWritableDatabase();
}

@Override
public void onCreate(SQLiteDatabase db) {
    try{
        db.execSQL(CREATE_USER);
        db.execSQL(CREATE_TAPCASH);
        db.execSQL(CREATE_BUS);
        db.execSQL(CREATE_SHELTER);
        db.execSQL(CREATE_MAP);
    }
    catch (SQLException e){
        e.printStackTrace();
    }

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
   try {
       db.execSQL("DROP TABLE IF EXIST " + USER_TABLE);
       db.execSQL("DROP TABLE IF EXIST " + TAPCASH_TABLE);
       db.execSQL("DROP TABLE IF EXIST " + BUS_TABLE);
       db.execSQL("DROP TABLE IF EXIST " + SHELTER_TABLE);
       db.execSQL("DROP TABLE IF EXIST " + MAP_TABLE);
       onCreate(db);
   }
   catch (SQLException e){
       e.printStackTrace();
   }
}

i'm using datasource class like teamtr**house did

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

public class GreenDataSource {
    private Context mContext;
    GreenSQLiteHelper mGreenSQLiteHelper;

    public GreenDataSource(Context context){
        mContext = context;
        mGreenSQLiteHelper = new GreenSQLiteHelper(context);
        SQLiteDatabase database = mGreenSQLiteHelper.getReadableDatabase();
        database.close();
    }
}

this's the activity that i'd like to put my database

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

public class RegisterActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.register_activity);
        GreenDataSource myDb =  new GreenDataSource(this);
    }
}
