In today’s fast-running world, the mobile app market is expanding exponentially, no business would risk missing their presence on either platform: Google’s Play Store, Apple’s App Store and Windows’ Market Place.
However, the major concern that businesses face is budgeting when going for native apps for each platform and that is where the cross-platform applications enter. It allows developers to create mobile applications that are compatible with more than one operating systems, in this case, iOS and Android. Cross-platform applications provide the ability to run a single code on any platform and thus enables a faster release of the product/software and with better quality.
Native v/s Cross-platform Applications
Although it is a constant debate that has kept the community divided for years. Some experts still favour native over cross-platform while on the other hand, companies like Uber are coming with their cross-platform framework to rewrite their driver app.
Here are some noticeable differences between native and cross-platform applications:
- Cross-platform applications cost relatively less than Native applications.
- In cross-platform applications single code can be used for multiple platforms whereas in native applications a single code works for a single platform.
- Cross-platform applications have a limited consistency with the UI components of the device whereas native applications are consistent with the UI components.
- Cross-platform applications are high on performance but face hardware compatibility issues whereas native applications have a seamless performance.
Benefits of Cross-platform Applications
- Code Reusability
The biggest upside that hybrid app development offers is the reusability of code. Since a single code can be used over multiple platforms, it saves a lot of time and efforts.
- Wide Market Reach
Hybrid apps have a wide market reach and offer a shorter time to the market. Also, it saves a lot of market efforts as the app is available on multiple platforms.
- Cloud Integration
Integrating to the cloud environment is really easy with the cross-platform applications as they offer universal compatibility.
Cross-platform applications are consistent in nature as they offer the same interface over every platform and also they yield compatibility with the UI components of a device.
It is comparatively much cheaper than native applications because here a single code needs to be developed for multiple platforms whereas in a native application different platform demands different code.
Basic steps involved in the Development of a Cross-platform Application
Step 1: Choose a development tool for your application
The market is filled with a number of development tools but it’s on you to choose the best one for your needs and purpose. Here are some of the best development tools available in the market.
- Xamarin (Cherished by developers, entrusted by the enterprise)
- ReactNative (Learn once, use anywhere)
- Flutter (Excellent native interface in no time)
- Adobe PhoneGap (Build astounding mobile applications)
- Ionic (Lightning fast speed)
Step 2: Design
For rendering a unique user experience it is important to address the needs of diverse platforms and UI guidelines. Before building the app it’s better if the developer is familiar with how the app operates on each platform so that they do not have to face any troubles later. Also having a deep understanding of how to navigate the cores of the platform to ensure it is handy enough is also crucial.
Step3: API Services
The straightforward approach for medium scale projects is to use a single API to deploy platform-specific mobile applications for iOS, Android and Web, however, this approach might result in bottleneck problem. It is better if the developers tailor an API service to the specific requirements by decoupling the API from other existing API services.
An approach known as dedicated API service can be established by exposing a set of related functionalities to the backend, with this approach developers can change the backend API independently. It also enables developers to break interdependency between team and product.
Step4: Divergence over Multiple Platforms
Divergence doesn’t always mean cross-platform, sometimes its about different capabilities and features of devices on the same platform like the screen size.
Some of the platform-specific attributes:
- Screen Size
- Touch and Gestures
- Push Notifications
Some of the device-specific attributes:
- Geographic Location
- Social Media
- Near Field Communications
Step5: Testing and Approvals
Testing is a critical step in your process towards developing an app, it is better to ensure your app has been tested over various dynamics and situations before it reaches the market. Testing has to be done over a wide range starting from developer-level unit testing to beta testing across a variety of hardware.
Approvals, on the other hand, might take up to a few weeks and is not much transparent, there is limited feedback on the progress until the app is rejected or approved.
Apple’s Appstore and Microsoft’s Marketplace both lock-down their devices and implement a meticulous app review process to maintain quality. Whereas Google’s Playstore and Amazon’s Appstore for Android are widely available and has no review process.
Now that the world is divided basically into two categories, i.e. Android and iOS, cross-platform application development is expected to gain a huge mileage and experience a boom in their demand. There are a number of cross-platform app development tools available in the market now and just all of them can cover Android, iOS and Windows app development.
And the question which cross-platform app development tool is the best? Well, it simply depends.
