Cross-Platform Problems and Solutions for Mobile Development

Mobile development has ended up being a common part of the software industry, and most developers understand the main problem organizations face when constructing a mobile app: cross-platform development. What alternatives exist for deploying an app to multiple platforms concurrently? Exactly what are the strengths and weak points of each platform?

The foundation of mobile development is the native application, however there are a growing variety of options: web apps provide a browser-based option, hybrid apps take advantage of web development skills in a native plan, and code translators use one platform’s native development skillset to the codebase of another. Nevertheless, the distinctions can be subtle, and every choice lugs its own set of downsides.



Native applications are developed from the ground up for a particular platform and tailored to fit it. The accurate, platform-centered nature of native development implies that these apps have no limitations in terms of access to APIs and device functions, efficiency optimization, and platform-specific best practices for user interface design. Preferably, every mobile app would be built this way: to fit its exact purpose while utilizing all the available resources.

Among the significant advantages of native mobile development is the accessibility of resources. As an example, developers targeting Android have the Android Software Development Kit (SDK) at their disposal, which includes a suite of tools to simplify the development procedure: the SDK Manager condenses updates and tool setups into a single menu, the AVD Manager provides access to the Android Emulator and other virtual devices, and the Dalvik Debug Monitor Server (DDMS) is an effective debugging tool, simply to name a few. iOS and Windows Phone developers have similar toolsets readily available in their SDKs, covering everything from the UI and device feature tools of Cocoa Touch in the iOS SDK to the real world screening conditions of the Simulation Dashboard for Windows Phone 8. These toolsets make native SDKs important and thorough resources.

Unfortunately, the native SDKs are all durable toolsets that a native developer needs to find out for each platform. To develop native apps from scratch (rather than through an intermediate tool), developers should be competent with the required language, IDE, and development tools for each targeted platform, and if developers with varied skillsets are not available, added developers must be employed. This can be a significant issue, offered the increasing push to develop on numerous platforms. As an example, according to DZone’s 2014 Mobile Developer Study, 62 % of respondents targeted both Android and iOS. The financial constraints of native development are a major consider the growing appeal of web apps, hybrid apps, code translators, and Mobile Application Development Platforms (MADPs), which permit developers to reach multiple platforms with just one tooling environment.



The skillset for building a fundamental mobile web app is more common than that of native development. Essentially, mobile web apps are simply routine websites enhanced to look good and function well on cell phones, and they can provide a quality app-like experience if the developer is really experienced in web innovations. Extensively comprehended front-end web development languages such as HTML, CSS, and JavaScript provide the logic behind a web app, and there are lots of devices and libraries out there to assist web developers direct their abilities towards cell phones. jQuery Mobile and Sencha Touch are two examples of mobile web structures that supply UI parts and logic for sliders, swipes, and other touch-activated controls that prevail to native mobile applications.

The neighborhood around open source web innovations is another vital difference in between native and web development. Web technologies like Node.js and AngularJS are some of the most popular tasks in the open source community according to GitHub data. This suggests that the community support and knowledge base around web innovations is broader than native technologies.

In addition to being a more typical skill set, mobile web development can likewise resolve a basic issue with native application development. Aside from possible browser compatibility concerns, web apps provide a near-universal cross-platform option. Most APIs and hardware features will certainly not be accessible by web apps, and because they are not discrete applications in the same way that native apps are, web apps can not be dispersed through usual methods, such as Apple’s App Shop and Google’s Android Marketplace. Web apps could be an especially versatile option, but they lack a presence on fundamental mobile circulation.



Numerous of the drawbacks for web apps are reduced by another cross-platform option built on the exact same core web development skillset: the hybrid app. Like web apps, hybrid apps need web development abilities, but unlike web apps, they include some native features to enable higher versatility. It gets the name hybrid due to the fact that it is built with web languages and innovations at its core. With the help of a native product packaging tool, it can be deployed much like a native app and access more native device capabilities (device APIs) than a pure web application.

A hybrid app is produced by first coding the application to run in the device’s native webview, which is essentially a stripped-down variation of the browser. For iOS this view is called UIWebView, while on Android it’s called WebView. This view can provide the HTML and JavaScript files in a full-screen format, and pure web apps can accomplish this full-screen view as well. WebKit is the most frequently targeted browser rendering engine due to the fact that it is used on iOS, Android, and Blackberry.

Where a web app really starts to end up being a hybrid app is when the app is positioned inside of a native wrapper, which packages the hybrid app as a discrete application and makes it sensible for app establishment distribution. In addition to the native wrapper, a native bridge permits the app to interact with device APIs, such as alarm settings, accelerometers, and electronic cameras. The native bridge is an abstraction layer that exposes the device APIs to the hybrid app as a JavaScript API. This is one feature that clearly separates hybrid and pure web apps, since web apps are unable to pass through the security structures in between the browser and native device APIs. Access to numerous of the hardware showcases on cell phones makes hybrid apps feel more like native apps than web apps from the user point of view.



Some devices can go even additionally in terms of taking a single codebase and deploying it on numerous mobile platforms. MADPs are development tools, occasionally including a mobile middleware server, that develop hybrid or native apps for each platform using one codebase. Some MADPs, such as Appcelerator’s Titanium and, can take advantage of native elements where native is required or greater performing. UI widgets might be native, for example, while a more flexible JavaScript API condenses the universal parts of mobile development and makes the most of code reuse. As more native aspects are presented, a few of the drawbacks of native development reappear, such as the costly requirement for several skillsets. MADPs are most beneficial in situations where an application needs to deal with many back-end data sources, many other mobile apps, or numerous running systems.

A less comprehensive but more straightforward option is to use code translators when constructing native apps for numerous operating systems. These devices take native code and translate it into another platform’s native code, or translate native code into a neutral low-level alternative, such as bytecode. One example is Google’s J2ObjC, which equates Java classes into their Objective-C equivalents, reducing a lot the initial development of an iOS variation of the app. Although it’s much more than a code translator, a product called Xamarin does something similar by allowing developers dealing with C# and.NET in Visual Studio to produce a native ARM executable. They can then take advantage of ahead-of-time (AOT) or just-in-time (JIT) compilation to run their apps on iOS and Android in addition to Windows Phone.

As is the case with hybrid apps, the UI presents an issue. Since UI development can not be translated between platforms, code translators still require a considerable knowledge of the native platform to write the UI. Simply puts, code translators can provide substantial advantages in terms of reducing development time, but they’re not necessarily a “write once, run anywhere” option.



Between native apps, web apps, hybrid apps, and the growing number of MADPs, there are a great deal of options for mobile development. It is essential to keep in mind that there is no one solution that does everything. Some sacrifice affordability and ease of access for pure native efficiency, UI for easy cross-platform deployment, or ease of development for native credibility. Even the simplest devices include some degree of a knowing curve. If a method without any give-and-takes existed, the market would embrace it en masse, and you would find out about it.

Due to the fact that there are trade-offs, developers and decision-makers will certainly have to recognize their needs, and the needs of their users, in order to identify the best method to strategy mobile development.
