Challenges Faced By Android App Developers

While developing mobile apps, businesses target Android due to its massive worldwide mobile operating system market share. Alphabet has made Android available as an open source mobile platform. Also, it updates the mobile operating system at regular intervals with new features and enhancements. But the penetration rate of individual versions of the mobile operating system differs.

Alphabet does not regulate the Android smartphones, tablets, and phablets manufactured by various companies. Hence, the devices manufactured by different companies come with varying hardware features despite being powered by the same version of Android. That is why; it becomes essential for developers build mobile apps by targeting a wide range of devices powered by different versions of Android.

While planning, developing, and testing the mobile app, they need to focus extensively on its accessibility, functionality, performance, usability, and security of the mobile app to keep the users engaged regardless of their choice of Android device. Also, they need to explore ways to make the app deliver personalized user experience across varying devices and operating system version. They further need to address a number of common challenges to develop a robust Android app.

Understanding 7 Common Challenges Faced by Android App Developers

1) Software Fragmentation

As mentioned earlier, the market share of individual versions of Android differs. According to the latest data released by Google, the most recent version of its mobile operating system – Nougat – has a market share lower than its predecessors – Marshmallow, Lollipop and KitKat. Each new version of Android comes with several new features and enhancements. The developers have to include specific features in the app to make it deliver optimal user experience by taking advantage of these new features. At the same time, they also need to ensure that the app delivers rich and personalized user experience on devices powered by older versions of Android. The developers have to target multiple versions of Android to make the application popular and profitable in the short run.

2) Varying Hardware Features

Unlike other mobile operating systems, Android is open source. Alphabet allows device manufacturers to customize its operating system according to their specific needs. Also, it does not regulate the Android devices launched by various manufacturers. Hence, the devices come with varying hardware features despite being powered by the same version of Android. For instance, two devices powered by Android Nougat may differ from each other in the category of display screen size, resolution, camera and other hardware features. While developing an Android app, the developers need to ensure that it delivers personalized experience to each user by accessing all hardware features of his device.

3) No Uniform User Interface Designing Process or Rules

Google has not released any common user interface (UI) designing process or rules for the mobile app developers. Hence, most developers build Android apps without following any standard UI development process or rules. When the developers create custom UI interfaces in their own way, the apps do not look or function consistently across different devices. The incompatibility and diversity of the UI affects the user experience delivered by the Android app directly. The smart developers opt for responsive layout to keep the UI consistent across many devices. Also, the developers have to test the UI of their mobile app comprehensively by combining both real devices and emulators. But often developers find it daunting to design a UI that make the app look consistent across various Android devices.

4) API Incompatibility

Most developers use third-party APIs to enhance the mobile app’s functionality and interoperability. But the quality of third-party APIs available for Android app developers differs. Some APIs are designed for a particular version of Android. Hence, these APIs do not work on devices powered by different versions of the mobile operating system. The developers have to explore ways to make a single API work on different versions of Android. But they often find it challenging to make the app work smoothly on different Android devices with the same set of APIs.

5) Security Flaws

Its open source nature makes it easier for device manufacturers to customize Android according to their specific needs. But the openness and its massive market share made Android vulnerable to frequent security attacks. There are many instances when security of millions of Android devices has been impacted by security flaws or bugs like Stagefright, ‘Certifi-gate’ mRST, FakeID, Installer Hijacking and TowelRoot. The developers have to include robust security features in the application and use latest encryption mechanism to keep the user information secure despite targeted security attacks and security flaws in Android.

6) Android Search Engine Visibility

The latest data posted on various website depict that Google Play Store has a much higher number of mobile apps than Apple App Store. Also, a large percentage of Android device users prefer free apps to paid apps. Hence, the developers have to promote their mobile apps aggressively to accomplish higher download numbers and implement app monetization options. They also need to implement a comprehensive digital marketing strategy to promote the app by targeting the most relevant users. Many developers have to avail the services of digital marketing professionals to promote their apps aggressively.

7) Patent Issues

The users have option to choose from several Android apps offering identical features and functionalities. But developers often find it daunting to build apps with unique features and functionality. They often include features and functionalities in the app that make it similar to a number of apps available in the same category in the Play store. Unlike Apple, Google does not implement stringent guidelines to evaluate the quality of new apps being submitted to its app store. Lack of standardized quality assessment guidelines often make developers address issues related to patent. Some developers have to design and modify their apps in future to avoid patent issues.

Most Android app developers nowadays work in agile development environment to build Android apps rapidly. They have to coordinate consistently with QA professionals, and participate actively in the mobile app testing process. Hence, the developers also need to address a number of common issues in Android app testing.

How to Create an Android App

A very simple and easy business model for making money online is to build an Android app.

Mobile apps are relatively simple to make when compared with PC software and distribution is also very easy thanks to the existence of mobile app stores that let people search for an easily download and buy your software.

Android in particular makes the process even simpler, thanks to the much simpler approval process for new apps compared with Apple and the lower cost for becoming a developer.

Getting Started – The Conventional Route

When you first get started, you will most likely take the conventional route of using Android Studio. This is the main ‘IDE’ (Integrated Development Environment’) that can provide you with all the necessary tools in one place and streamline the process with helpful tips, straightforward testing and the like.

This can be downloaded from the Android developers website and should come with the Android SDK included. That SDK is one of the key tools that you’ll need – it’s a set of instructions you can access that specifically relate to the capabilities of Android. You will also need the Java Development Kit (JDK).

From here you’ll be programming in Java and writing code that refers to the Android SDK. Unfortunately, you’ll likely find that this is all a little complex not only to use but also to set up.

For that reason, many people will decide to take other routes…

Other Options

There are several other options when it comes to building Android apps. One is to use ‘app builder’ software which will allow you to build apps without knowing any code. These are very limited in terms of what you can build though and they take away a lot of freedom.

A ‘compromise’ position then would be to use something like Basic4Android. Basic4Android is a tool that makes coding for Android much simpler and easier and even streamlines the testing process. If it’s a game you’re looking to make, then a similar options is to use Unity which will make it much easier.

Then of course you can always outsource the creation of your app, though it’s often harder than you might expect to find a capable of coder.

The best option for a marketer interested in making money then? That would be to simply buy an app and then promote it! Find a good app that isn’t selling much, email the creator and make it your own!


Use Mobile App Templates When There Is A Need For Speed

Inspiration for mobile app design is important. When you decide to build a mobile app for your business, you automatically start imagining how it should look and how it should work. Well, it gets confusing at times and you just wish there could be some reference or some template that you can look at and build upon.

This is exactly where mobile app templates can help.

Ready to use

For any industry vertical or for any type of business, a ready to use mobile template can save you a lot of time and energy. You do not have to imagine the design and the logical flow of elements from scratch. It is all provided and ready to use. You know exactly how your finished product will look like. Moreover, if you feel the need to change some features or some elements, a developer can easily do that for you.

Speed

If you need to go mobile quickly, using a template could be your best bet. A template has all the design elements built in and all you need to do is to customize it to suit your business. If you start from scratch, your mobile app will take quite a while to be ready. With a template, you can get it developed with months.

Cost

Paying a designer is going to cost you. Well, downloading a ready template could be cost effective and yet very appealing. You get templates that are completely customizable, so if you are worrying about the uniqueness, it’s totally up to how skillfully you customize it.

Choice

If you think your options are limited, you are wrong! There are abundant templates available online for you to download and use instantly! You can then decide how you can modify the look, feel and colour scheme of the application.

Functionality

The look and feel of your mobile app is one part and the features and functionality is another. Well, the logical flow from one screen to another is already thought of and presented to you in a ready template. The good news is that you can remove and add any screen and modify the template as you wish. That’s the charm of using a ready template.

Customization

If you think that if you download a ready template, you are stuck with a design that a hundred others are using, you are wrong! These templates can be easily customized to maintain the uniqueness. Designers can easily read the code provided by the creator and add their own code to add features and functionality that your business requires.

Well, the good part is that these templates come with an open source code. So, you can hire designers of your choice to complete the mobile app for you. Well the ability to customize what you have downloaded enables businesses to use the same template that has been downloaded by a hundred other users and yet create a unique looking application that does not match any other!

Factors to Consider While Choosing Mobile Development Framework

Developers, these days, have a good number of options while choosing a mobile development framework. However, not every framework enables you to build your app the way you want. Each one will have its unique features and issues. Here are some factors to consider while choosing a mobile development framework.

Paid or free

Licensed versions will have more features compared to freeware; however, the choice depends on the requirements of the application to be built. Many free platforms enable you to build popular app types including content apps, social media apps, games, mapping and navigation apps, etc.

Technologies it supports

Java, HTML, CSS, Java Script and jQuery are some basic technologies you can expect from a good framework. More and more developers are turning to HTML5, as it makes cross-platform app creation easy and cost-effective.

Multi-platform compliant

There are many models of mobile devices available in the market today, each with its own platform. iOS, Android, Blackberry, Palm WebOS, Symbian and Windows to name a few. In the initial stages of app development, a developer could create an app for a single platform only. However, the evolution of cross-platform frameworks (and HTML5) enabled cross-platform mobile app development and expanded the options for developers. If you plan to use your app on more than one platform, be sure to find a framework that enables you to do so.

Conversion to native apps

Most systems will help developers build web apps, but converting them to native apps is a lengthy and difficult process. There are very few platforms in the market that enable developers to convert web apps to native apps in one click.

Recompiling

While developing apps for multiple platforms, compiling an app for each and every platform is a pain-staking process for developers. If there is a small change to the source code, entire app needs to be recompiled for the changes to apply. Check if your framework eases this recompiling issue for you.

Enterprise data synchronization

This is important for business apps with frequently-updating content. You need a framework that will help your mobile device communicate with a SQL server database. Not many frameworks provide this feature. If your app requires such technology, you need to recheck if it is supported by your mobile development framework.

Though there are many mobile development frameworks, very few provide the space and support the developers look for. The above factors will help you in choosing a right mobile app development framework.
