How to Build Apps for Barcode Scanners

October 1, 2024/in App Development, apps, Low Code, Mobile /by Erin Cavanaugh

Handheld barcode scanners are indispensable in many sectors today, from retail and logistics to healthcare, shipping, and manufacturing. These devices play a critical role in capturing real-time data, such as inventory updates, order tracking, and customer details. However, integrating scanned data seamlessly into backend systems is just as important as collecting it. Barcode scanner apps can bridge the the gap with the ability to transfer scanned information to databases and business systems.

While the need to integrate barcode scanner data into mobile apps is a common requirement, building scanning apps is often a challenge. Traditional development methods require specialized expertise and can take too long, especially in industries that demand rapid deployment.

Support for connecting to barcode scanners in Altova MobileTogether changes all of that. With this low-code app development framework, you can create, test, and deploy barcode-scanning solutions in a fraction of the time compared to conventional coding approaches.

Modularization for App Development

September 10, 2024/in App Development, Development, mobile development /by Erin Cavanaugh

In programming, modularization is the practice of dividing functionality into separate, independent modules. Modularization in app development is an efficient way of organizing app components and enabling collaboration within development teams. A modular approach also helps make testing, debugging, and maintenance of the app easier and more straightforward.

MobileTogether offers some classic – and some unique – approaches to modularization.

Configuring MobileTogether Server to Work With Your Network

April 1, 2024/in App Development, mobile development, MobileTogether /by Ty Shuff

Configuring MobileTogether Server to work properly on your network will require some changes to be made. MobileTogether Server is designed to sit within your network’s DMZ, and enabling it to accept connections from clients both inside and outside your network will require your network administrator to open a collection of ports.

This video tutorial will walk you through the ports required to make MobileTogether function. It provides you with a baseline setup that will work inside most corporate networks. Please note, however, that every network is different and some configuration changes may be required. To support this, every port MobileTogether Server uses can be customized; all the ports listed in this tutorial are default and can be changed.

The image below outlines the network ports required by Altova LicenseServer to properly validate files.

Clients will need to be able to connect both internally and externally. We recommend using the default MobileTogether ports, and remapping them to 80 and 443 at each of your firewalls. This is discussed in greater detail in the video.

Finally, a set of ports will need to be opened for administrator purposes. These ports should be limited to your internal network only.

Using a Reverse Proxy Server

When setting up a MobileTogether Server for a public-facing app that will be accessed via URL in a web browser (in addition to from MobileTogether client apps), it may be helpful to hide the precise URL that is being used on the server to start the solution.

Solution URLs follow this convention: https://server.name/run?d=/public/SolutionName. You can customize the URL to hide the “run?d…” portion by deploying a reverse proxy server in front of the MobileTogether Server.

Refactoring Mobile Apps

March 6, 2024/in App Development, Mobile, MobileTogether /by David McGahey

The best ideas for new features and other improvements to existing software apps often come from enthusiastic users. Implementing new features creates opportunities for refactoring mobile apps. After several years using the MobileTogether Solar Data Tracking app to monitor the performance of a rooftop solar system, my friend Casey had a suggestion.

The app displayed one page of charts and tables to report production by month over a year and another page to report daily production for the last 30 days. Navigation buttons on each page enabled easy switching between views. Casey’s suggestion was to revise the app to place all the charts and tables on a single page. Over time mobile users have become accustomed to mobile apps that present data in long pages that scroll with a quick one-finger swipe motion. A one-page app would feel smooth and more up-to-date.

Building Apps with an Intelligent Database Wizard

March 20, 2023/in App Development, Database, Development, Low Code /by Erin Cavanaugh

Data-driven solutions like database and enterprise apps rely on connection to, and interaction with, backend databases. Backend relational databases, however, store data in tables that reflect complex data relationships. This provides numerous advantages for effective data management and data integrity but can make it difficult to access and work with the data stored therein in new ways. App developers need to have a comprehensive understanding of database design principles and the SQL query language just to get started.

In contrast, real world data relationships most often represent parent-child relationships or even deeper hierarchical structure. As such, working with hierarchical data where relationships can be visualized in a tree structure can be much simpler and more flexible, leading to faster development. This approach is also more accessible to developers without extensive SQL expertise.

To make building apps that connect to the backend relational databases that are ubiquitous in today’s enterprise easier, faster, and available to a wider range of developers, Altova MobileTogether takes an entirely unique approach. Its visual Database Wizard lets developers easily build a query that returns hierarchical data, work with that data in the app, and then easily save the data back in hierarchical form, letting MobileTogether take care of normalizing the data and writing it back to the corresponding linked tables. Let’s take a look at how it works.

Role-based Access Control in Enterprise Apps

March 1, 2023/in App Development, Database, No Code /by Erin Cavanaugh

Enterprise database apps are increasing in prevalence due to their advantages for enabling access to—and easy management of—the ever-growing amount of critical data business users need to work with on a day-to-day basis. Unlike other types of business productivity apps, database apps must include measures for managing different levels of user access to maintain the security and integrity of the enterprise data they expose.

This can include managing read-only and editing access rights or restrictions on access to certain types of data. While it is essential to ensure that only authorized personnel have access to confidential data, levels of permissions often vary throughout an organization. Apps built using Altova RecordsManager include comprehensive tools for managing role-based access to database data that can reflect these complicated relationships that exist within an organization.

Let’s take a look at how RecordsManager makes it easy for app administrators to manage complex role-based permissions with visual tools.

Scripting App Behavior

February 17, 2023/in App Development, Low Code, No Code /by Erin Cavanaugh

The low code approach to app creation has been very effective at decreasing the complexity and learning-curve associated with building custom apps in response to quickly changing business requirements. Low code tools do the heavy lifting for developers and system administrators, freeing them to focus on business needs and rules rather than writing complex code.

To be truly successful, any low code approach must still include the ability to configure sophisticated app behavior in response to user input. This can be a challenge to implement with visual tools.

Altova RecordsManager offers a low code approach to creating database apps, with a built-in scripting editor that is purely visual. This offers the best of both worlds: easy app creation and sophisticated functionality customized for data-centric applications. Let’s see how it works.

Mobile App Themes Improve User Satisfaction

March 2, 2022/in App Development, mobile development, MobileTogether /by David McGahey

Mobile app themes improve user satisfaction by letting each user customize the app appearance with personal preferences. One way to implement multiple themes in apps that report and visualize data is to offer users a choice of color palettes for charts and graphs. MobileTogether uses a combination of drag-and-drop UI design, the powerful Action Tree visual programming language for event handling, and standardized functional programming for data selection and processing. Developers use MobileTogether every day to create elegant cross-platform apps with rich charts and graphs in all popular formats.

The main chart configuration settings let mobile app developers choose any of four built-in color palettes or even define a custom color palette for charts and graphs as they design an app. Combined with dark mode and light mode display settings, that creates ten colorful possibilities for display customization. Rather than impose a design-time color choice, developers can leverage MobileTogether features to let users choose for themselves. Let’s look at an example.

Maintaining Low Code Apps

September 24, 2021/in App Development, mobile development, MobileTogether, Tools /by David McGahey

Low code software tools can speed mobile application development by freeing developers from routine coding tasks and encouraging focus on high level app requirements. However, some developers, project managers, and even entire enterprises remain wary of low code tools. These stakeholders are afraid testing and maintaining low-code apps will be more difficult and costly over time.

But not all low code or RMAD (Rapid Mobile App Development) tools are alike. A low code tool that is simply a user interface to a code generator and builds apps from a set of templates could be attractive to an inexperienced developer. When an issue arises, a highly skilled programmer might need to diagnose and modify the generated code for each mobile OS to create a solution.

MobileTogether is a cross-platform RMAD tool that works differently. MobileTogether uses a combination of drag-and-drop UI design, a powerful Action Tree visual language for event handling, and standardized functional programming for data selection and processing. MobileTogether includes a built-in Simulator window to instantly execute the app to test logic, view the UI as it will appear on a variety of iOS, Android, Windows, and other devices, and examine changes in workflow data during execution. MobileTogether also includes sophisticated automated testing features and a built-in debugger to test and debug apps with precision and examine app behavior directly in the design environment.

Let’s look at how some real-world app maintenance requirements are simplified in MobileTogether.

Mobile App Development: A User Story

May 21, 2021/in App Development, mobile development, MobileTogether /by David McGahey

Ahh spring! Birds singing, flowers blooming, and the sun rises earlier and sets later. All that extra daylight gives solar power generation systems more hours to make electricity. As the summer solstice approaches, solar generation systems enter their most productive time of year.

Owners of rooftop solar systems can be passionate about tracking their productivity. The actor and comedian John Hodgman even moderated a disagreement over obsessive monitoring of solar production. My friend Kasey is also enthusiastic about solar power. Whenever I see Kasey, she reports her latest kilowatt-hours stats. Kasey’s home is in a warm, sunny climate where air conditioning is her biggest electricity demand. She installed solar panels on the roof of her house at the end of last June and her system raced to generate enough power during long summer days to offset her air conditioning.

After receiving the electric bill for August, Kasey called her solar installer to report success – her home’s electricity consumption for the month was zero. “I have to confess, I read my meters every single day to see how the system is doing,” Kasey told the installer.

“Everybody does it,” the installer replied. “Some users even tell me they check the meters three times a day!”

Kasey asked me if a mobile phone application built with MobileTogether might make a good reporting tool for her solar power system. “I could enter the meter readings into my phone,” she said. “I can do it every day when I take the dog out before breakfast.”

That’s how our mobile app development collaboration began. The result is the MobileTogether app we call Solar Power Tool.

Create Mobile Apps that Automatically Support Dark Theme

December 28, 2020/in App Development, mobile development /by David McGahey

Android and Apple mobile devices support a display option called Dark Theme, which you can think of as almost a negative image of the normal screen display. In Dark Theme white is black, black is white, and color intensity in general is adjusted. Dark Theme reduces power requirements, which can extend runtime for a battery charge, and can be easier to view in low light.

Altova MobileTogether includes features to let developers create mobile apps that automatically support Dark Theme by detecting the user setting when the app is launched.

Let’s look at an example:

Mobile App Debugging

August 5, 2020/in App Development, mobile development, MobileTogether, Tools /by David McGahey

MobileTogether is a tool for building highly complex, elegant, cross-platform solutions. Developers need mobile app debugging tools to troubleshoot during development and understand app behavior. The MobileTogether Designer offers full-featured debugging of app execution flow inside action trees and debugging of XPath/XQuery functions. These features are provided in two mobile app debugging views integrated into a single tool.

The Actions Debugger view allows developers to debug the Actions of a Control event or a Page event. This view is available when an Action that has been selected for debugging is encountered during processing. The XPath Debugger view opens the XPath/XQuery evaluator window for in-depth tracing and debugging of expressions.

Developers can set breakpoints at various locations and the app, then execute one step at a time, pausing in either view to allow examination of the complete execution environment.

Let’s see mobile app debugging in action:

Design Templates for Mobile Apps

July 28, 2020/in App Development, mobile development, MobileTogether, Tools /by David McGahey

In an earlier post we wrote about using software design templates for mobile apps to facilitate design reuse and make it easy to build efficient, flexible options for various app requirements. We described an example of a Control Template designed to present multiple levels of hierarchical data based on user selection at runtime.

Our example was built using MobileTogether, Altova’s RMAD (Rapid Mobile App Development) tool to help developers build cross-platform apps that deliver dynamic, sophisticated app performance that delights end users.

You can also build Control Templates for cross-platform mobile apps by combining multiple controls into a larger unit, like a complex sub-assembly built from individual parts. This creates design templates for mobile apps that can easily be dropped in anywhere, speeding development and ensuring consistency.

Visual Feedback in Mobile Applications

April 4, 2019/in App Development, Mobile, mobile development, MobileTogether, Tools /by David McGahey

Visual feedback in mobile applications provides a more enjoyable user experience, and mobile apps that are fun to use get launched more frequently than static, boring apps. MobileTogether, the rapid mobile app development (RMAD) framework from Altova, incorporates all the tools you need to develop cross-platform mobile apps with attractive visual feedback features.

The drag-and-drop controls palette in the MobileTogether Designer includes a button control that automatically changes its appearance when clicked. You can also define conditions that add or change text, images, or other features of any button as the app executes.

Additionally, many other controls can also be defined to act like buttons, where one or more actions are performed when the control is clicked. We have written previously about applying icon images as tool buttons in mobile apps to create a stylish and elegant menu of tools. In this post we will add interactivity to our tool images to provide attractive visual feedback for each click.

Enabling Let’s Encrypt in MobileTogether

March 6, 2019/in App Development, mobile development, MobileTogether /by Ty Shuff

MobileTogether Server, the backend hub for apps built in MobileTogether Designer, now supports the ability obtain SSL certificates using Let’s Encrypt. Let’s Encrypt is a free service aimed at encrypting all HTTP traffic on the web. This feature is supported in MobileTogether Server starting with version 5.1 and adds to the ability to upload your own certificate.

The video tutorial above walks you through configuring MobileTogether Server to utilize SSL encryption when communicating with MobileTogether clients. It covers the use of both Let’s Encrypt and certificates generated using a trusted certificate authority.

SSL certificates generated using a trusted certificate authority can be uploaded directly to MobileTogether Server. This configuration can provide several advantages to system administrators. These types of certificates are typically good for a much longer period of time, requiring fewer maintenance windows. In addition, you can keep your MobileTogether Server completely isolated from the outside world as this method does not require any external ports to be opened. The process to obtain these certificates can be much more complex and expensive. Verification typically requires you to provide information to the issuer and wait for a response which can delay your implementation.

Let’s Encrypt integration was added in MobileTogether 5.1. Let’s Encrypt is a certificate authority whose goal is to provide encryption to the entire Internet. Certificates generated are free of charge. Unlike other methods of generation, though, Let’s Encrypt certificates are only good for 90 days. MobileTogether Server is capable of automatically renewing these certificates every 60 days, but requires a scheduled server reboot each time this action occurs. Lastly, Let’s Encrypt requires your server to be accessible from the outside world; they will need to communicate with MobileTogether Server on port 80 to verify your server’s identity.

The ability to encrypt communication between client and server is becoming ubiquitous. MobileTogether allows you to easily secure all communication to your mobile clients using SSL encryption and new support for Let’s Encrypt greatly reduces the set up complexity.

We have written previously about Integrating APIs and Mobile Apps to create a rich and entertaining user experience. Since publishing our previous post, we continued to enhance the GPS demo app with additional API support to get current weather conditions and scheduled events nearby.

One challenge with offering all this functionality on a small mobile screen is to provide users with a clear, consistent, and easy to use navigation scheme across all views in the app.

Applying icon images as tool buttons in mobile apps can create a stylish and graceful navigation menu, especially if the icons are chosen based on recognizable and commonly-agreed conventions. For instance, an arrow pointing left often indicates go back, and a floppy disk icon frequently represents save data, even when the ultimate destination might not be a new file nor a disk.

In this post we will describe how to use image icons to build cross-platform navigation menus with tool buttons in mobile apps using MobileTogether.

Early Software Testing Validates Design

“Test early and often,” is a strategy from agile software engineering that has evolved to become a mandate for software developers in every field. Early software testing is especially important for developers working on cross-platform apps, who must support mobile devices with varying physical characteristics and operating system functionalities.

MobileTogether includes features to incorporate early software testing into the development process without time-consuming compile, deploy, and debug cycles for each mobile platform. The Altova Web site describes the MobileTogether Simulator early software testing feature, and we have blogged about the ability to record and re-run specific sets of actions in test cases.

This post describes Trial Run on Client. It’s built into the MobileTogether Designer to let developers instantly examine app designs and validate logic and functionality across any supported mobile device or platform – Android, iOS, and Windows Desktop or Windows Phone.

Developing enterprise apps often involves integrating text that includes embedded formatting information in the form of rich text – whether it’s from back end CMS systems or content entered directly by users.

The Rich Text control in MobileTogether makes this easy.

MobileTogether gives developers holistic access to the rich feature sets of mobile devices for cross-platform deployment of native apps for Android, iOS (iPhone, iPad), Windows 8 & 10, Windows Phone 10, and HTML5 browsers for other users. MobileTogether apps created from a single design can seamlessly access mobile device camera, messaging, GPS, audio, email features, and even feature mobile app calendar integration.

Since MobileTogether uses a combination of visual drag-and-drop UI design and easy-to-understand functional programming for data selection, it’s easy for any programmer or web developer to build highly sophisticated apps to read and write calendar events for all platforms. For instance, a mobile scheduling app for a large, distributed user base could help everyone easily sync their calendars.

How to Make a Pop-up Window in an App

During mobile app development there’s often a quick action the developer wishes to let the user to complete or a message that can be delivered on top of the current app view – otherwise known as a pop-up window. These are useful for letting the end user complete a process or view a message payload without interrupting his or her progress in the app.

MobileTogether makes it easy to configure pop-up windows of any size. Let’s take a look at how it works.
