9 Advantages of Custom Android App Development

The Android app development platform is a great choice, if you are not going for cross-platform app development. They have many advantages that other platforms can’t offer. This platform allows you to develop feature-rich applications with great functionality and usability.

Android, as an open source operating system is used by the majority of mobile phone manufacturers to power their devices. This creates tremendous business opportunities and augments growth.

Most of the off-the-shelf applications available today are highly customizable products. Yet, custom android app development is gaining so much importance.

Let’s see some of the advantages that are characteristic of custom apps alone.

Android Apps Offer Perfect Solution for your Distinctive Needs:

Every business is different, and therefore needs a different solution for their unique business requirements. Packaged products often come with excellent quality and reliability, but they can ultimately be an impediment to your business goals.

Readymade products are designed to meet the requirements of a wide range of businesses. It may include many functions and services that you may not find to be useful. As a result of these unnecessary feature assortments, more system resources are used which will eventually slow down the entire process.

Most of the time, packaged app users may find it necessary to adjust and alter their business operations to accommodate the application. A custom application could always prove to be a better solution than standard solutions, no matter how much customizable it is.

Tailor-made, innovative and individualized processes gives custom apps the flexibility to suite your businesses’ in-house operations. Also, custom apps can be localized to maximize use and increase productivity.

Custom Apps can Save your Time and Money

App development costs can be highly deceptive. The cost of developing custom android app may or may not be lower than purchasing out-of-the-box solutions. But, it helps to stay on time and on budget during the development period.

Readymade apps will not include the costs for installation, customization, data import, training the workforce, and additional support. The long-term benefits of custom made business applications are far better than that of the readymade ones.

Another advantage of custom android app development is that you will have to invest only for those specific set of features that you ask for. You can also exclude recurring licensing costs that come with off-the-shelf products, since you own your custom app.

Very Few Complications and Compatibility Issues

As your application is customized and designed from the very beginning in accordance with the end user requirements, it will be quick and easy to use. Very little training will be required as the application is less likely to include elaborate and irrelevant operations.

There will be very few complications when you operate it with the business software and applications that you already use. With licensing business applications, it is usual to encounter continuous errors while working with it.

Increased Business Security

Custom applications always give you enhanced security. Your product is exclusively built for your business alone. Other application vendors and users outside your enterprise will not have any clue about the architecture of your application.

Hackers often attack the known vulnerabilities in the applications. So business security risks are very high for third party applications

Efficient and Reliable Technical Support

One of the major benefits that come with custom apps is the unparalleled technical support plan that the Android app development companies offer. You will get reliable, dedicated support from the team that was directly involved with your product development. The users are promised with quicker and efficient solutions to all the encountered problems.

BYOD Preference for Android Apps

From the market share of Android apps, it’s quite evident that it has a prominent role when compared to other platforms. Companies who wish to bring in their own policy (BYOD), it’s feasible to opt for custom Android app development as it is available for a wide variety of devices and has high popularity with users from all economic groups.

Easy Customization

Android provides the opportunity for developers to create versatile apps through their easy customisation feature. Be it a complex custom app or a web app integration, this platform provides ample space for easy customizations. This platform is designed in such a way that it can accommodate any requirements of a business and also offers flexibility to integrate multimedia tools, data management functions, and with regular updates.

Open Source and High ROI

Android’s SDK is available at free of cost, thereby minimizing the cost for software licensing. As it is a free open source framework, it enables development of apps without any extensive development costs.

Use of Wearable Devices

Among business, the use of wearable devices is flooding due to its quick communication functionality. As the market for wearable devices is considered to grow more than 45% in the coming years, Android is contributing a lot to bring in the best devices in the digital market for the sake of the users.

Conclusion:

If you have a strategy for developing a custom app and wish to choose a single and stable platform, then Android app development is the feasible option. It’s the most recommended platform because of its market perpetuation, ease of development, integration, and short span of development.

Security Checklist to Consider for Android App Development

Thousands of apps are being released to major app stores every day. Yet, most of them wither before they even have a chance to bloom.

The effort, money, and time that is put into developing apps are enormous. Once you’ve got a lot of negative feedback from the users, there will be hardly any second chance given to prove the worth of your app. So ensuring security should be a major step taken by app development companies.

Security check is implanted into all the latest releases of Android app development to bring in a number of features for its users.

As security has become more of a concerning element for Android users, Google has launched a new security-focused page on Android developers site. This site provides tips for app creators to make their apps free from issues.

Some of the most common security vulnerabilities of android apps include the following:

1. Inadequate Transport Layer protection
2. Client side injection
3. Poor authorization & authentication
4. Security decisions through untrusted inputs
5. Broken cryptography
6. Lack of binary protections
7. Improper session handling
8. Unintended data leakage
9. Insecure data storage
10. Weak server side controls

Android operating system has several built in security features which makes attacks less frequent. These features allow enabling security easier during android app development. The main in-built security features include the ones given below.

•  Android Application Sandbox can be used to isolate the app data and code execution from other apps.
•  Data can be protected using an encrypted file system in case of device loss or theft.
•  Application data can be controlled by enabling application-defined permissions.
•  It enables user granted permissions. This will restrict access to the user data and system features.
•  Includes technologies to reduce memory management errors which include ASLR, ProPolice etc.

Since ensuring the safety of user data is a very crucial step in confirming your app’s success following the given below security check-list is important for every app developer:

1. Apps should use permissions that are necessary for integrated features. Developers should pay more attention to the permission factors that are used by the app’s libraries

2. The registration and activation process should be well made.

3. Never store sensitive information on external storage, since the data will become very easy to exploit.

4. Network transactions should be adequately protected as it involves transmission of private data.

5. Strong input validation is very important for app security.

6. When using native code, attacks that can be induced from data coming over a network or IPC should be controlled by carefully handling the pointers and managing buffers.

7. Use parametrized queries to submit to SQL database in order to stay safe from SQL injection.

8. JavaScript injection is a common web security issue when using the WebView as it makes use of website content that will include HTML and Javascript.

9. Use authorization token instead of frequently asking for user credentials so as to reduce fishing attacks.

10. Android offers a lot of methods to protect data, such as data isolation, entire file system encryption, cryptography, and secure communication channels.

11. Its better to use Android based Intent, Binder, or Messenger than Linux based network sockets and shared files to execute IPC.

12. In Android, Intent is preferably used towards an application component for asynchronous IPC.

13. For RPC related IPC, using Binder or Messenger is preferred, which can ensure mutual authentication of endpoints.

14. Loading code from outside of your application APK, can increase the risk of code injection.

15. Use of sensitive APIs and data from external storage should be verified as safe enough before using it in an app

16. Properly configured SSL should be in place to secure communication between clients and servers.

17. A new building block is introduced for anti-abuse- SafetyNet attestation(it’s an API for developers to vaguely evaluate whether the used Android device is genuine)

18. As several untrusted contents are handled in web view improvements are made in Android Lollipop. Now the Web View is showcased as an independent APK with regular updates

19. Mandatory use of application sandbox (a security mechanism to separate running programs to execute untrusted programs/codes)

20. Enhance security with Device Management Solutions

21. Methods to defend users against PHAs (Potentially Harmful Applications)using Verify Apps, which potentially enables steps to validate threats targeting the system

22. Verified boot is a protection layer that help to improve security checks using cryptographic integrity to detect changes in the operating system

23. Android O has now introduced “seccomp” (a security measure used in Linux kernal) which stops the exploitation by potentially harmful apps.

These are the few best practices that needs to be considered to maintain security while Android app development. Whether you are an Android developer or an entrepreneur, knowledge on a few caveats is important to set the right place in app market.

Where to Start Android App Development?

“Where to start android app development?” This is a question that every budding developer has faced in the beginning of their journey. App development is not just about learning the code syntax. There are a whole lot of tools and Android app development software that you need to get familiar with.

This article will help you to get started.

The Android Software Development Kit

The SDK comprises of a collection of tools that helps you in android app development.

The IDE is a part of the SDK, and is the main program that lets you write code, organize and edit various files, call libraries, perform testing etc. There are two important IDE for Android, viz., Eclipse and Android Studio.

Eclipse: It is the default IDE for Android, which allows you to work with Java and XML files.

9 Tips to Prepare for an Android App Developer Interview

Android is the most popular mobile platform currently. A career in android app development would be many fresh graduate’s dream job. Well, not so fast. The first skill you need to have is the skill of cracking the android app developer interview.

Several things are known by all like the importance of having a well written resume, being honest, using a good body language, reaching the site early etc. But, most will be ignorant about ways that could make them stand out or face job interviews confidently.

The following tips will help you in preparing for an Android app developer interview in a better way.

1. Be Prepared for the Whole Interview Experience

Attending the interview is not just about being prepared to answer the technical questions alone. While you have to work your way around that, nailing the non-technical and non-verbal part has got a huge impact on the success of your overall performance at the interview.

You should be prepared to answer all those friendly questions along with the uncomfortable ones like why you were jobless for a certain period. You should be prepared for the tricky questions as well. For e.g. if the interviewer asks you, if you are more comfortable working with a team or alone, you should answer the question taking into consideration the nature of the company.

So many candidates leave the interview without asking further questions to the interviewer, thinking that it’s not their business or that the interviewer might feel irritated. This is not a recommended practice as showing your curiosity in knowing the details convey your interest in proceeding further.

2. Be Yourself and Don’t Bluff

Whatever you know, answer it confidently. If you are asked a question that you don’t know, tell them that you are not sure and then continue with the answer. Never try to explain a wrong answer confidently. That can make your interviewer doubt on your correct answers also.

3. Keep Updated about the Latest News and Trends in the Industry

Even though you might not be able to have a detailed knowledge about everything, it will always give you an upper hand when you are aware about the latest trends and technology in the android app development industry. So, listen to tech news constantly and make it a habit to research about similar topics. You can follow known bloggers and watch Google I/O. This will give the interviewer an idea about how interested you are in the field.

4. It is not Enough to know the Languages Alone

It is often a misconception that having an in-depth knowledge about the programming language is what makes you a top developer. Well, this is definitely not so. Make sure that you have enough idea about the android app development process as a whole – from conception of a project idea to marketing tactics. Even possessing a certain level of entrepreneurial spirit will prove beneficial in a developer’s career.

5. What Exactly do you Know about the Company?

This tip can seem so obvious, but most are careless even to go through the company’s website before appearing for the interview. Research well about the company’s background so that you don’t have to face an embarrassing situation while attending the interview. Speak about your interest in working with them. Always remember that this is a chance which you could cleverly use to impress the interviewer.

6. Develop an App to Showcase your Skills

Rather than explaining your skills and capabilities, it is better to show them in real. You can either develop a new app or focus on improving your college project if that is good enough. You can keep your project updated when you advance with your skill set and experience. The point here is to show than to tell; giving a reason for the interviewer to feel convinced is your own responsibility.

7. Data Persistence

Every application needs to store data either as a cloud file, template files, temporary cache, etc. Since mobile platforms are resource constrained, it requires more care while choosing the right strategy. During an interview, be confident to talk about the alternate persistence strategies and also how you can combine different storage options. Having a deep knowledge of hard technical details can be more important than just knowing the theoretical generalities.

8. Knowledge on tools

It’s quite certain that bugs might occur while app development. Your speed in determining where and what went wrong can portray that how good you are as a developer.

You might be asked to debug a problem within a sample app during an interview. So, be sure that you are familiar with the common templates for detecting such vulnerabilities.

9. Know what you’re doing

A vague idea and understanding of technical concepts cannot get you much farther in an interview. If you don’t know something, don’t be afraid to say so. Know the purpose behind every code and functions during development and how it contributes to solve problems.

Overall, maintain a good attitude, no matter what happens at the end. Take every chance as a learning experience to sharpen your interview skills for the next time. Good luck!

Please feel free to share any more ideas you might have.
