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.

Search Missing Phone Feature
If you have misplaced your Smartphone or left it somewhere in the house, you don’t have to become panicky. The search engine developed by Google would find it for you within seconds. The users just need to type in the command ‘Find my phone’ on a search engine feature to know the approximate location of the device. The company talked about this feature in a blog post. Only catch is that new searching feature only works with Android phones. This means that mobiles using other operating system cannot be tracked at all. The feature also helps the user to lock and erase the data off if he or she feels that his or her device is missing. The feature does this job remotely. The user doesn’t have to report to the customer care centre for locking the stolen device.
How it Works?
Normally, the Android Device Manager allows the user to ring his device from anywhere. The users can use this functionality to find a missing device. They need to keep the ring option on. After that, the feature would make the phone ring for about five minutes and wait for the device to reply back. This period is long enough to help the people easily find the missing phone. Besides this, users have to make sure that the tracking service in their phones is switched on. In order to make use of this feature, the users have to install the latest version of the Google application on their registered device. The ringing functionality works well with the place tracker to find the device. If there is no response, the feature cautions the users to decide whether they should lock their device remotely. After getting the reply, the feature remotely removes data and locks the device.

So you must have started seeing Oreo in many devices as Google expands its rollout. The most popular devices to carry Oreo are Google Pixel, Pixel C or Google Pixel XL and Xiaomi. Many companies like Huawei, Samsung, Motorola, Sony, HMD Global etc have been confirmed to support the update later this year. The company announced Project Treble (for those who do not have Google-branded phone) to ensure that Android Oreo update comes to many more devices than previous operating system.
Coming to the features and functionality – Is it what all you can do with when the new update arrives?
- Smart text selection
The text selection feature in Android Oreo is going to 'Rock' – as the OS will know to select all the text, when you try to copy and address. Smart text selection feature has the ability to tap on the selected text.
This feature makes it easier and quicker to use the device. If it is an address, it will begin direction there. And if it is a phone number, you can dial the number directly from the screen.
- Video Multi-tasking
This is not entirely a new feature, but can be said as an advanced version of existing multi-tasking feature. The picture-in-picture feature of Android Oreo allows users to switch from one screen to the other easily.
For example – if you are watching Netflix, and you suddenly remember an email you forgot to send, you can keep Netflix on small window and send email at the same time. This feature is great on large and medium screen phones.
You will be able to pop a video screen out of its application into a small panel on screen, allowing you to use the phone while keeping an eye on the action. You will certainly appreciate the greater versatility and multi-tasking benefits offered by this OS.
Android Oreo allows the notification dots to appear above the apps that have pending notifications. This feature was not enabled in previous versions, making it difficult to view new notifications. You can carry out with a single tap on the dot to get contextual menu actions.
Google introduced notification spots to apps in Android Oreo, allowing users to quickly see what is happening without the need to open the app. You can simply swipe the notification bar and get details about the notifications you have. This feature is similar to Apple's 3D Touch enabled bubble pop-ups. A long press on the small colored circle on the top rich of the app icon will pop-up the display and show more information.
Users need not go through the pain of typing information each and every time, as the 'Autofill' feature in Android Oreo fills the information automatically. The information is filled by the OS automatically from the app or web.
Remembering the long passwords is hard. However, it is to stay safe when you are online. The previous version of Android OS allowed you to use a number of weird workarounds to help you copy and fill in your account details.
The new version Android Oreo allows apps to register, as the autofill providers within the system log you in. All you need to do is pick autofill provider in any language and input settings. Android will request login details form the app whenever you need.
- Adaptive app icons
Google is encouraging its users to interact more with app icons through this new update. It is providing developers with tools to make the interactions a bit fun and engaging.
The app icons could come alive when the users interact with them or scroll through homepage screens. It's potentially a new feature and we are more interested on what developers can do with it.
- Great speed and performance
According to Google, Android Oreo will load the apps and boot the device at double the speed of Android Nougat, resulting in slicker operation. Google's done with a whole load of work under the good to make faster iteration of its mobile platform. This enhancement will likely improve the performance of even the cheap devices.
Google also limits the frequency of location updates in background for better health of the system. It is two faster than the previous generation with faster boot. App developers will love this feature.
- Great power to Google Assistant
The new OS Android OS gives additional powers to Google Assistant making it a lot more useful. Google Assistant will be open to developers, who can leverage it within their applications. This means, it can be used inside the application, serving to bolster the usability of applications in long run.
This sort of innovation is needed, if it is to become indispensable. Google ensures that Assistant grows and evolves beyond smart devices.
- Play more with new emoji
There is no doubt that emoji are firmly enriched in our day to day life. They have got their own movie for crying out loud. Google committed itself to the latest additions of the ever expanding emoji family in Android Oreo.
When it comes to presenting the users with fresh emoji, Google falls behind Apple. The inclusion of latest expressions will likely delight the Homeland Generation. You can find more than 60 new emoji. The best this is Google is going to redesign the entire emoji catalog. So, keep out for fresh new look when Android Oreo lands on your device.
- Save Battery life
The main focus of Android Oreo is battery life, speed and security with great control over the apps. Google is moving slowing in the direction of its rival Apple's iOS with great restrictions on what all you can do with app. The restrictions places on background apps reduce the performance demand on device, speeding up the operation. This means all the devices will see more battery life once Android Oreo is installed.
Google says that Android Oreo is much smarter when it comes to let apps run in background, reducing the amount of power and money they use. This leaves more of the battery to use in tasks that you use regularly.
- Keyboard navigation
The biggest improvement in Android Oreo is the keyboard navigation. Users are allowed to navigate easily with a more reliable and predictable model for "arrow" and "tab" navigation. This feature helps both end users and developers.
Beside the above, Wi-Fi awareness is the new feature in Android Oreo that allow Wi-Fi devices to talk to each other via an ad hoc local network. Google is set to add Sony's LDAC codec to improve low-latency audio. You can also see a few improvements to the camera app. Google is reworking on the camera app, offering a new double-tap feature to quickly get 50% zoom. Android app developers believe these new features will be a game changer for them.
Finally, no Android OS would be complete without Easter egg. However, the one we see in Android Oreo is not the most impressive one we have seen till date. Go to settings and tap System -> About Phone. You will see big Android O. Tap it repeatedly to get an octopus.

Do you wish to kill your free time when the only company you have is your Android phone? Did you know that Android games are the most interesting and fun filled stuff to cram your phone with? Go through this article to know more about these games and their fun factors.
Android games are diversified into many categories; informational, educational, shooting games, puzzles, sports, racing, augmented reality games, location-based games and more. All these types are available for both high end and low-end Android phones.
There are low specification games for those low-end models so that you can enjoy them in your budget phones as well. This includes the less graphics content games that does not take much of your space. It is suitable for Android phones with low GPUs and smaller screen size as well.
Both freemium and premium games are available in the stores. Premium are paid-for games and freemium is the free games which often contain in-app purchase at certain levels. So it is advisable to monitor if someone other than you (like your kid) is using your phone; do not click on those purchase options without knowledge.
To enjoy the best high graphics and well-designed gameplay, it is better to get a high-end model with a larger screen and good GPU. Even you can enjoy those high-quality gaming effects by increasing the performance of your low spec, budget Android phones.
First and the simplest method to increase your low-end smartphone performance is by killing the applications that are running in the background before you start the game. You can use several task killer applications for this, as well. Most of the Android phones contain many applications that are of no use to an average user. These applications can be disabled which in turn increases the performance of your phone.
All you need to do is, go to settings, select 'apps', then select the applications to be disabled and click the 'disable' button. All these applications can be enabled in the future if you need them. Typically, the uninstalled applications or your internet browser often leaves behind junk files. These cache data often reduces your phone performance. To clear these data, go to 'settings' and click 'storage option', then select the cached data button and press okay.
Always opt for a class 10 SD card to increase your phone's gaming performance. Using these SD cards will increase the read and write speed and hence decreases the loading time and other lags that any high graphics game would demand. Thoseoted Android phones have more facilities to increase their performance. The background task killer applications work to their fullest only if they are in aoted Android version. Seeder software can be installed in aoted Android phone, which reduces the lag during switching between applications.
