Converting an iOS App to Android

Converting an iOS App to Android
If you want your app to reach the most customers, converting your iOS app to Android needs to be on your mobile developers’ shortlist.

Your company has an iOS app to Android that performs excellently and is well received by your users. However, while Apple’s mobile platform remains highly popular with many zealots, the Android user community boasts a larger user community. So if you want your app to reach the most customers, converting iOS app to Android needs to be on your mobile developers’ shortlist.

The best strategy for mobile app development from iOS to Android depends on the nature of the original codebase. Not surprisingly, smaller apps with a minimal dependence on high-end graphics and video are easier to convert. In fact, multiple tools exist for cross-platform mobile development that also target desktops and web browsers. Unfortunately, the cross-platform approach typically won’t work for large enterprise apps or those leveraging rich media, including gaming. 

In these scenarios, building a native Android app development from the ground up makes the most sense. Sure, the developers are able to reuse some of the app’s resources, including boilerplate graphics, back-end database designs, and more. Most of the code, however, needs to be written from scratch. So let’s take a closer look at a 2021 project where we converted an exceptional iOS app to the Android platform.

Why Convert an iOS App to Android?

As noted above, Android remains the most popular mobile platform with a larger mobile app userbase compared to iOS. In fact, Android currently enjoys a 72% share of the global mobile market. If your company wants to reach the most users for its mobile app, targeting both platforms is a must. Sure, leveraging a cross-platform mobile development tool works for simple apps, but most high-end enterprise app experiences require taking a native development approach.

Last year, our CEO Andrew Amann built SaaS analytics and charts by hand for startup partners using another tool. After seeing the buzz about ChartMogul, an iOS-based analytics platform, he decided to check it out and found it was a game changer for this kind of work. However, he wondered on Twitter why ChartMogul never built an Android version, while also dropping the fact he leads a top shelf digital venture studio. ChartMogul’s CEO and founder soon responded asking for a quote to build that Android version.

The moral of the story is simple and worth repeating: targeting both major mobile platforms allows your app to reach the widest possible audience. Now let’s dive into the details on converting an iOS app to Android.

Differences Between the iOS and Android Platforms 

Significant differences between the iOS vs Android platform add to challenges for multi-platform mobile app development. Android developers must deal with a larger variety of OS versions and devices compared to the walled-garden of iOS. The operating system differences include changes in navigation, file management, and notifications from version to version. These issues typically aren’t managed well when using a cross-platform mobile development tool. In short, software engineers must write code to handle each targeted Android OS version.

One option to mitigate this issue involves only supporting more recent versions of Android. The iOS team that built the original app likely made a similar choice regarding older versions of Apple’s mobile operating system. Decide on OS version support during the initial stages of the project.

In most cases when converting an iOS app to Android, redesigning the UI is another must. Again, the myriad of Android devices with varying screen sizes adds a measure of complexity to this effort. Also consider the differences in screen controls between both platforms, like buttons, lists, tabs, and more. So craft new wireframes if deciding on an Android-specific UX for the new app.

Also keep in mind Android compatibility for any Android app development tools and libraries used by the iOS development team. Make sure everything in your software engineering toolbox supports both platforms. Additionally, expect to rewrite the mobile app’s source code considering the language differences in app development between both platforms. iOS development primarily uses Swift or Objective-C while most Android apps are coded in Java or Kotlin.

Expect a more vigorous mobile app testing process for Android apps considering the vast number of devices and operating system versions. Note that deciding on supporting only a few Android versions mitigates this effort somewhat.

Steps For Transforming an iOS App Into a Native Android App

Let’s break down the process of converting an iOS app into Android into a few steps.

  1. Determine which Android versions to support and any compatibility issues with the original iOS code, tools, and library support. Use this information to inform the app design and wireframing process.
  2. Build the new Android app, leveraging the requirements and UX wireframes defined in the first step.
  3. Complete a rigorous QA/testing process before the app’s release. Again, the Android OS and device differences require a focused effort from your entire team.
  4. Release the app!
