How can I make an Android SQLite database that uses my laptop as a server?

I currently have a DatabaseHelper class in my code (extending SQLiteOpenHelper) which creates a table and inserts values into it. The problem with this however is that my app will store data of various users, which can be accessed by users - so doing it this way means that if (for instance) I registered an account in my app on one device, that account wouldn't exist on any other device (since the database is stored in the operating system itself).

For now, I want to use my laptop as a server for the database so that I will be able to log into the same account using any Android device. I installed sqlite on my desktop but I don't have a GUI or anything with it (and am really unsure how to use it). I already have logic for creating a table / inserting data etc. in code - would it be possible to keep this code but store the data somewhere on my laptop instead?

Here is the current code I have:

public class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME = "Accounts";
public static final String TABLE_NAME = "account_table";
public static final String COL_1 = "ID";
public static final String COL_2 = "USERNAME";
public static final String COL_3 = "EMAIL";
public static final String COL_4 = "PASSWORD";

public DatabaseHelper(Context context) {
    super(context, DATABASE_NAME, null, 1);
}

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("create table " + TABLE_NAME + "(ID INTEGER PRIMARY KEY AUTOINCREMENT, USERNAME TEXT, EMAIL TEXT, PASSWORD TEXT)");
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS "+ TABLE_NAME);
    onCreate(db);
}

public boolean insertData(String username, String emailAddress, String password) {
    SQLiteDatabase  db = this.getWritableDatabase();
    ContentValues cv = new ContentValues();
    cv.put(COL_2, username);
    cv.put(COL_3, emailAddress);
    cv.put(COL_4, password);
    long result = db.insert(TABLE_NAME, null, cv);
    return (result != -1);
}

public int Login(String username,String password)
{
    String[] selectionArgs = new String[]{username, password};
    try
    {
        int i = 0;
        Cursor c = null;
        SQLiteDatabase db = this.getReadableDatabase();
        c = db.rawQuery("select * from " +  TABLE_NAME + " where username=? and password=?", selectionArgs);
        c.moveToFirst();
        i = c.getCount();
        c.close();
        return i;
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
    return 0;
  }
}

Thanks in advance for any insight!
