The Google Maps Platform Android SDK supports extensions for reactive programming, which helps you write code to handle asynchronous operations.

Write reactive and responsive mapping applications with Google Maps Platform

In mobile apps, asynchronous events can happen at any point in time: user touch events, waiting for network calls to complete, or receiving push notifications, to name a few. As an app developer, accounting for these events and composing them with other asynchronous events can be challenging. Reactive programming is an alternative to passing callbacks for different events and helps simplify the process of working with asynchronous events. In reactive programming, events are modeled as a stream, emitting items over time.

There are two libraries you can use to write reactive code: Kotlin Flows and RxJava. The next two videos show you how to use each one.

Writing reactive and responsive mapping applications using Kotlin

If you’re a Kotlin developer looking to use Coroutines and Flows, the KTX library allows you to use Kotlin Flows to receive events. The Maps KTX library includes extension functions that return Kotlin Flow objects, so you can listen to events in a reactive manner. Unlike suspending functions, which return a single value, Kotlin Flows can return several values over time. For example, you can use a Flow to receive camera event changes over time. To get started using Kotlin Flows in your app, include the Maps KTX library in the dependencies section in your build.gradle file.

Creating reactive maps on Android with RxJava

Integrate Google Maps Platform SDKs with popular Android library RxJava. RxJava is the Java implementation of Reactive Extensions, which is a library for composing asynchronous and event-based programs using observable sequences. One thing RxJava does is allows you to convert callback-based asynchronous code into a chain of transformations. Learn how this works and the other ways you can use RxJava in the third video in this series.

When Bigbasket was founded in December 2011, it guaranteed to deliver goods within a one-hour delivery slot of its customers’ choosing or it would refund them 10 percent of their orders. The company also introduced an express service, delivering groceries within 90 minutes of an order being placed.

Bigbasket needed a mapping platform that could help it meet its delivery times, and offer a familiar interface to customers. MediaAgility, a digital consulting company, recommended Google Maps Platform to Bigbasket.

When customers use the Bigbasket mobile app to place orders, they select their locations on a Google Map. The prices and availability of groceries varies according to location, so a customer’s location determines the cost of the order and what can be ordered.

Google Maps Platform Results

• Bigbasket handles more than one million orders per month, and delivers in more than two dozen cities in India
• Bigbasket now has more than four million customers
• Orders are delivered on time, increasing customer loyalty

It is also used to determine driver routes. Bigbasket used the Maps Javascript API to build a web-based app for the company’s backend that tracks all orders and delivery progress. Dispatchers use the Directions API to match drivers with orders and customers, and the Distance Matrix API to get estimate the time of arrival for deliveries. As dispatchers track the progress of deliveries on the map, they can tweak routes as necessary.

“We’ve built Bigbasket from the ground up using Google Maps Platform. It makes sure we have the right customer locations and deliver to them on time. We couldn’t have started Bigbasket without Google Maps. It helps us to be fast and efficient, and make sure our customers get what they’ve ordered quickly,” said Pramod Jajoo, Chief Technology Officer, Bigbasket

In the last two decades, BHI, once a small construction company in Vernal, Utah, has expanded its operations to dozens of industries in over 25 states. But while the company grew, its technology trailed behind. File sharing and emails both ran off a single server. Editing a document was a grueling undertaking that required an employee to VPN in, patiently download the file, edit it, then upload it again—all from a job site with a limited internet connection. Acknowledging the need for better technology, BHI adopted Google Workspace and AppSheet and transformed its business to be more innovative, productive, and profitable.

Rebuilding collaboration and productivity

BHI first looked to replace its archaic email and file-sharing systems. They found that Google Workspace—as a proven and popular collaboration solution for remote teams and a familiar, preferred platform that most employees use in their personal lives—was the clear choice. BHI migrated its 500 employees to Google Workspace in less than a week. Productivity immediately soared, since employees could collaborate more easily with Google Workspace’s products and access them from any device, from anywhere—even at the construction sites.

For instance, the contract writing process drastically improved with Google Workspace. Version control had always been a struggle—as employees circulated a draft contract from one computer to the next, versions became unruly and randomized, untracked changes popped up, and files went missing. With Google Workspace, the pre-construction, legal, and finance teams can all edit and track changes of a contract from wherever they work. Version control has become a thing of the past, as everyone is always working on the latest version.

By adopting Google Workspace, BHI decentralized its operations and began collaborating in real time across over 150 job sites. Management and IT gained new insights into challenges that they may never have uncovered nor confronted without a cloud-based productivity tool. The IT team also saw an opportunity to overhaul the methods of their deskless workforce, which accounts for 90% of the company. This deskless majority needed to connect directly to the data that influenced, impacted, and comprised their work. They also required more streamlined processes. AppSheet provided the answer to the workforce’s needs, enabling IT to create applications that simplified key tasks so mobile workers could get their jobs done faster and better.

For example, one BHI client required extensive inspections multiple times a day. Before using AppSheet, a BHI inspector would perform the inspection, return to a computer, record the results from paper to a spreadsheet, copy and paste them into a formatted report in a Google Docs, convert the Doc to a PDF, and email the final inspection report to the customer. This manual process took two hours to complete. Now, using AppSheet, the inspector inputs the results on their mobile device while performing the inspection. As soon as the device connects to the internet, it automatically updates the database with the inspector’s inputs, adds the inspection results to a preformatted report built-in Google Docs, and emails the final report as a PDF to the customer. With AppSheet, BHI shortened this inspection process from two hours to six minutes, saving over $50,000 a month in labor. “With Google Workspace and AppSheet, BHI has turned into a digital company with real-time data allowing for real-time decisions, collaboration, and transparency in a decentralized environment,” says Johnny Hacking, Director of IT.

An easier software choice for faster results

BHI also found that building apps with AppSheet is much easier than using other solutions, such as developing with low- or full-code tools or purchasing third-party products. Because AppSheet is a true no-code platform, anyone can learn to build and maintain apps. Since adopting AppSheet, the BHI IT team has become so proficient with the platform that they have eliminated the company’s previous backlog of software needs. Now, when a new site opens up, IT proactively works with the site managers to understand its unique requirements in order to build a custom app. Start to finish, scoping, and building this site-specific app typically takes less than a week—compared to months with traditional development platforms. 

IT team members aren’t the only BHI employees building apps. As Hacking explains, “We have people that aren’t in IT, and when they have an idea we say hey, log into AppSheet, build it out, and then we’ll help out with some final touches on it.” 

Empowering employees outside of IT to build AppSheet apps has benefited teams across the company. For example, one team on a solar farm construction project needed to perform inspections of an array of specialized technical equipment with which IT was not familiar. In this case, the solar team, being the subject matter experts, simply built the app according to their specifications. All IT had to do was jump in at the end to help finalize the app—the final product was completely customized to the solar team’s very specific needs. This highlights the benefits of no-code development: on-the-ground experts build and prototype job-specific apps and IT puts the finishing touches on the functionality, all while keeping guardrails in place.

Using Google Workspace and AppSheet also simplifies BHI’s reliance on third-party software. “Our company divisions are so diverse that they each require different software,” says Hacking. “Plus, if we buy a third-party software, we still have to customize it by getting other software, because they don’t play well together. By replacing this software with AppSheet apps, we save a lot of money. And it’s easy to integrate those apps because on the back end, they’re all connected to Google Sheets.” 

For the few third-party software products that BHI hasn’t been able to replace, they’ve used Apps Scripts to import the software’s data into Google Sheets, so that their data all lives on one platform. Overall, BHI has been able to free up 10% of its total IT spend by replacing third-party software with Google Workspace and AppSheet apps.

Company culture transformed by technology

“Because we’ve used Google Workspace and AppSheet and it’s been so successful, people are very willing to use them,” Hacking says. “And for a construction company to gain so much trust in these platforms in such a short period of time—that’s huge. Now we’re at the point where employees are asking, ‘What else can we do?’”

Adopting Google Workspace and AppSheet has not only made BHI more productive, but also transformed the company culture. Employees feel empowered to be more innovative and are constantly seeking ways to improve. Simplifying employees’ work has led to a direct boost in morale. 

The role of IT has also transformed. As Hacking explains, “In just three years of using these technologies, IT has gone from being support overhead to being proactively brought to the table to take part in the business strategy.” Increased IT visibility and culpability has helped solve business problems and led to increased profitability. 

BHI continues to find new ways to leverage Google Workspace and AppSheet to improve business. In response to COVID, they created a timesheet app that allows employees to clock in without touching a device. Most meetings are now held virtually using Google Meet. Fleet maintenance and repairs are all managed with apps. And, of course, the company has better data and insights than ever. As Hacking puts it, “We’re continuing to stay on the cusp of innovation because of Google Workspace and AppSheet.”
