Mistakes To Avoid While Developing An Android App?

Mistakes To Avoid While Developing An Android App?

Android is one of the most preferred platforms for developing apps. 85% of smartphones are using Android OS. With such popularity comes high competition. There are a total of 2.8 Million apps in the Google Play Store which you should know if you are looking forward to developing and launch your Android app.

With such heavy competition, there is no room for making any mistake if you want to survive in the competition and be able to generate revenue out of it. An Android training institute must teach what to do while developing an app but it is equally important to teach what not to do at the same time. Here are some of the most common mistakes you should avoid while developing an Android app.

1) Rewrite Existing Code

It is one of the most basic mistakes in Android app development. Certain features like social login, JSON parsing, network calls, database access, image loading, etc are most probably used in the majority of the Android apps. Rewriting code for the above-mentioned features is a huge mistake. It consumes a lot of unnecessary time. These features already have ready-made codes that are written, tested, and used plenty of times to date. Now, rewriting already written code is a mistake you should not make as an Android developer. Instead, you should do some research about already available feature codes and which of them can be used in your app.

2) Using Improper Bitmaps

Smartphone users love accessing content through visuals and most probably the images. One of the issues with an app filled with images is higher memory consumption and loading time. The image has to be loaded in the memory before it loads on the screen which needs usage of bitmaps. Bitmaps are one of the most common techniques used by Android developers for this. However, it is extremely important to understand the concept of bitmaps and use it properly. Make sure to measure the view where you are going to display the image, scale it and show only what can be displayed.

3) Not Following List View Hierarchy

Developers are already using deep view hierarchy for a long time for the layout. The layout consists of an XML presentation in Android. For drawing the necessary content, XML has to be parsed, the screen size has to be measured and elements have to be placed appropriately. This entire process needs to be optimized and can be time-consuming with a whole lot of resources involved. By using the list view, the hierarchy can be flattened and make the entire process optimized. This is what makes the developers save their time and make the development fast.

4) High Waiting Time

Data packages are not sent on the instant. It takes time to get acknowledged, processed and get received. There is a mandatory time delay in the process which makes the users wait. There are cases where there might be network issues and the packages get high time to delivered or the worse gets destroyed in the way and it never gets completed. The probability of success calls is more as compared to the unsuccessful ones. However, a single occasion of failure or long waiting time will make the users abandon the app.

So, you will know what you should be doing in your Android classes but what you should not be doing can be learned from this blog. Stay tuned to Developers Academy blog for more interesting do’s and don’ts for developers.

Features of Xcode 10 You Should Know About

Xcode 10 is a comprehensive toolkit that allows the developers to develop apps for iPhone, iPad, Apple Watch, Apple TV, and Mac. Major functionalities include OS frameworks, simulator bundling, and instruments for SDK creation for iOS 12, macOS 10.14, TVOS 12, and WatchOS 5. It is a complete package that enables the developers to build a responsive and highly functional app. The newer version of Xcode allows developing an app that is customizable according to the idea and data. Here are some of the astonishing features of Xcode 10 every developer must know about.

1) Dark Mode

While using Xcode 10, the macOS Mojave avails a new dark mode feature. It allows the developer to shift dark mode by using system preferences. The basic idea of adding this feature to this toolkit is to add an attractive element to the apps. The entire interface will be transformed into dark including fonts, icons, the contrasting color of the jump car, and many other elements. Xcode provides tools to make these dark mode apps with ease.

2) Instant Swift Source Code Editor

The newer version Xcode 10 also allows the functionality of the fastest code editor. The text scrolling is even more seamless when it is involved with the source file editing. Designing animations will be much easier if you are folding the code for increasing the focus. It also easy to spot a mistake and fix it. Also, there is a markdown structure that helps in the documentation activity. One of the best things is that whenever any developer makes any change in the code locally or globally, it will be highlighted beside every line. If you are looking to join iPhone training, make sure to learn the Xcode 10.

3) Debugging Tools

Xcode does offer debugging tools that allow developers to select from the light or the dark mode of the interface. The developers can also make changes in the macOS runtime by using the command Debug> View Debugging> Appearance menu. The inspector exhibits the named color while view debugging showing their names and telling whether these colors are system colors or not.

4) Playground for Machine Learning

It is a model just like REPL that assists in rerunning the current playground code immediately. REPL is basically an interactive programming language which intakes single user input and gives the result to the users. After that, the developer has to run the code in a particular line.

The alternate option is to type the shift return for running the code. Import or take the create ML framework to create the new models and then write the code for testing the model in the playground. After completing the task, take your model in the app.

5) Faster Creation of Apps

The Xcode 10 has Swift 4.2, one of the most advanced versions of iOS programming languages for building mobile apps at a faster pace. It has a quick compilation making it possible to deliver the app in the decided time. Compared to the Swift 4.0 version, the Swift 4.2 version is more efficient with developing big and complicated apps with double speed. Xcode 10 also provides a build system which is a great addition for speeding up the development process. It also helps in different functions like editing the code and testing it and keeping track of the speed of the workflow on a routine basis.

Everything You Need To Know About Material Design For Android

Material design is basically a guide for visual, interactive, and motion design across different devices and platforms. Now, when it comes to integrating material design into Android apps, there are certain guidelines laid down which are mandatory to follow. The developers can also take the benefit of the new styles and components in the material design support library. Learn about the APIs and patterns of the material design that can be used in an Android app.

New API for the custom animation and shadows.
Widgets for complicated views like cards and lists.
Material design theme for the app for styling all the UI widgets.

The Android developers who have the experience of working on projects must know by now how to use material design in the Android apps. For the newbies, learning these things can be difficult, joining Android classes can be a good option for them. Let’s list down elements of material design to be integrated into the Android apps.

1) Animations

The new animation API will allow the developers to build custom animation for touch feedback in the user interface controls, activity transitions, and changes in the view state. These API would allow you to perform various things like:

Show and hide views with circle reveal animation.
Give response to touch events in views along with the touch feedback animations.
Develop increased natural animations using curved motion.
Display animations into a state list drawable in the middle of the view state changes.
Switch between various activities using custom activity transition animation.
Animate the changes in multiple view properties using view state changes animations.

2) Drawables

The new additions to the drawable will allow the developer to integrate material design into the Android app.

Vector drawables are easily scalable without compromising on definition are apt for the single color in-app icon.
Color extraction allows the developer to extract prominent colors automatically from a bitmap image.
Drawable tinting allows the developer to define bitmaps in the form of an alpha mask and tint them with a new color during the runtime.

3) Cards and Elevation Shadows

Along with the X and Y properties, there is also a Z property in the Android Views. The new property signifies the View elevation which shows:

Shadow Size: Views with higher Z values provide bigger shadows.
Drawing Order: Views having higher Z values will get displayed on the top of other views.

The elevation is generally applied when you have a card-based layout which allows the developer to show essential pieces of information in a card that delivers a material look.

4) Material Theme and Widgets

To make the most out of material features like styling as per the standard UI widgets, you can apply a material-based theme to your app. Read the below points to know how exactly you can apply the material theme and widget to your Android app.

Display the navigation, search, brand, and other actions with the App bar.
Show and hide the navigation of the app with a Navigation drawer.
Promote the main action of the app UI with Floating Action Button.
The developer can make use of one of the many material components for the layout of the app and its navigation. There are tabs, a bottom navigation bar, collapsing toolbars, and many more options to choose from.

Where Can You Learn Material Design For Android App?

Any Android training institute will include material design in its Android course. However, if you are looking for the best Android classes, Developers Academy is the one you should choose. Along with the material design, it also includes guaranteed placement and job opportunities.

Java Vs Kotlin for Android: Which is Better Choice For Building Your Next Mobile App Project?

Java has always been he go to language till the past many years. However, with new languages popping up, the dominance of Java is decreasing with time. After Google announced Kotlin as the official programming language, Java has got a hit and for Kotlin comes humongous popularity. Android developers are in a serious dilemma which one to pick when you are developing your next Android app. Here is a comparison of Java and Kotlin with a conclusion of which should you prefer for the next project.

Java Vs Kotlin for Android Project

Java Programming Language

It is developers favorite when it comes to development and of the strong reasons behind that is Android itself is written in Java. It is an Object-oriented programming language which has received the title of second most active language on GitHub. Java is used for Android development for the last 20 years and it has grown a lot in the past few years.

Pros of Java

=> Learning and working is easy
=> Flexible working with the option to run on a web browser or the virtual machine. This will be of great use while reusing the code and updating software.
=> Android SDK has several Java libraries which makes Android bit dependent on Java.
=> Allows quick assembly within Gradle which comes in handy while assembling huge projects.
=> Large open-source ecosystem.
=> Apps developed with Java are highly compact and are easy to optimize for better performance is required.

Cons of Java

=> It needs lots of memory and is slow compared to some other programming languages.
=> It needs to write more code keeping a room open for errors and bugs.
=> It has certain restrictions which cause trouble for Android API design.

Kotlin Language

Designed by JetBrains to add modern touch and features to Java. The language was working well but gained another level of popularity after being announced as the official programming language in Google I/O in 2018. Google has already switched to Kotlin, Have you? It is an open-source language typed statistically based on JVM. You just need to install the Kotlin plugin and allow it to configure to your project.

Pros of Kotlin

=> Speeds up the development and can also be used in the backend project like Spring 5.
=> Because of the scripting ability, it can be easily used in the Gradle build scripts.
=> Shifting from Java to Kotlin is easy, just install Kotlin plugin, add the same to Gradle build files and press Convert.
=> Support several modern programming functions.
=> Needs lesser coding and more expressive than Java which leaves lesser room for errors and bugs.
=> Compatible with all the frameworks and libraries and can be integrated with the Gradle and Maven build systems.
=> Adoption of Kotlin is easy and can be done by taking training from any Android Training Classes.

Cons of Kotlin

=> Steep learning curve which is both a pro and con when shifting the entire team to Kotlin.
=> Compared to Java, it has slower compilation.
=> Smaller developers community which makes getting answers and resources to learn a bit difficult.
=> Most of the Kotlin developers would still be in the learning phase and finding an expert would be difficult.
=> It’s a highly declarative language and hence tend to create a huge amount of boilerplate in corresponding JVM bytecode.

Conclusion :

Kotlin has more advantages than Java but, has certain shortcomings as well. If you are a newbie, it’s advisable to learn Kotlin as it is modern, in trend and highly demanded. Also, if you are an expert you can’t afford to be the left out one for the advanced programming language. So, it’s a clear answer, choose Kotlin for your next Android app.

What Is The Process of Becoming An Associate Android Developer?

You must have heard Android developer but Associate Android Developer (AAD) must be a relatively new term for you. It is a certificate provided by Google which puts a label on your developer’s career. Android app development is not that big of a deal but, developing a glitch-free and flawless android app is a big deal. Also, proving that to the client and getting the project becomes a difficult job. This is where a certificate helps and what can be better than getting it from Google itself.

What is the Associate Android Developer Certificate?

It is a Google Developers Certificate which is issued directly from the company of which the tools are being used. The certificate is recognized on global platforms which are of great use for the freelance Android developers looking to work for the international clients. It will convince the clients about the expertise of the certificate holder in the field of Android development.

How Can A Developer Become Associate Android Developer?

The process is quite simple, the candidate just has to appear and pass an exam on Android SDK, Android Studio, and one of the programming languages either Java or Kotlin. There will be nominal fees to be paid and provide identity proof. Once the above steps are completed, you will be given eight hours to complete the exam.

If you have submitted the exam successfully within 8 hours, the next step is to finish an exit interview. This step includes sending over a recording of the spoken answers. If you clear this round, you will then be handed over the certificate.

How Much Does It Cost To Become An AAD?

The costing of AAD certification is not relatively high. The average fees of appearing for the exam is $149. However, it might differ a bit based on the location. The fee is non-refundable. This means if you are not able to clear the exam, you will have to pay again.

Criteria of Android Associate Developer Exam

The exam is aimed at the beginner level Android developers. Hence, this certificate will be available to everyone having even the bit of experience with Android. However, you will have to study and prepare for the exam. Google does provide certain content to prepare for the exam as a guide.

• Features and functionality of the app.
• Usage of Android UI framework.
• Using the Android framework for storing and retrieving data into the mobile environment.
• Debugging the app.
• Testing the android app.

It is advisable to take the basic training from an Android training institute to save yourself from paying twice.

Importance of Associate Android Developer Certificate

It depends on your level whether it is what you really need or not. If you are a student this is of great use to you. The certificate will help you to get a job or convince the client and hand you over the project. However, if you are already an experienced developer having worked on several projects with a portfolio, this certificate would not be of great use to you. This is basically for beginners to prove their knowledge. Experienced already have a portfolio and work to show to the clients, they don’t need a certificate.

How To Kickstart Your Career As A Web Designer?

Before you decide to frame your career as a web designer and join the web design training institute, it’s very important to know this field. Web designing is the front end through which a website makes its first impression. It’s a huge responsibility and needs a creative aspect. If you have a creative insight, interest, and passion, and basic knowledge of the correct colors, you have the green signal.

Web designing is a wide field. There are various things involved to become a good web designer. You will need to learn HTML, XML, and CSS. They also have to learn tools like Photoshop, Sketch, Illustrator, and such others. The IT field has been competitive than ever before. And as we discussed design is the first thing the user looks at in a website which makes the role of designer very important.

A website is visited from many different devices and designer have to make a design that is compatible for devices of all types and all sizes. This concept is known as responsive web design. Back in the date, there was very limited OS working with limited hardware devices. This is clearly not the case at present which makes web designing training a need of the hour. Modern designing is complicated and for a shining career choice, training is a must. Now, if you have decided to enroll yourself for training, be careful while choosing the website designing classes.

Here are some of the things to take care of while choosing it:

1) Curriculum

If your agenda is to develop a website for your own, you might not be needing in-depth knowledge or training. However, if you are choosing it as a career choice and want to make money from it for the rest of life, the scenario is quite different. For career-oriented designers, the curriculum is very important. They must be in the know of what exactly is expected from them when they are hired at a corporate job and MNCs. Pick an institute providing curriculum and teaching what is needed and in demand.

2) Training Certificate

Choose web designing classes which provide certification of the training taken at the end of the training period.

Also, make sure to choose a reputed and popular company which will make help you when you are giving interviews for the job. The interviewer will be able to pour trust if the training institute has a reputation.

3) Live Project Training

Bookish knowledge is not of much use when it comes to the real world. Showing videos and tutorial won’t help much in the corporate job, it’s the real-time experience that will come in handy. Hence, choose an institute which provides live project training. Everything that is taught must also be implemented adequately in live projects.

4) Faculty Demo

Name and popularity of the classes matters but ultimately it’s the trainers that matter. They are the people under whom you are going to get trained. Take a demo lecture under the trainers to check their knowledge and how they impart it to their trainees. It’s important to know their expertise and experience before you start learning under them.

Swift is Now Available For Android App Development

Shocked or confused? Well, any of the situations you are into, it’s pretty much expected. Swift is the leading programming language for iOS app development and the sudden usage for Android is astounding. Well, it is not a bluff, it is the reality. Till date, Swift was considered to be replacing Objective C for developing iPhone app and now it seems to be stepping into Android OS.

The whole buzz is about SCADE SDK (software development kit) which has made this possible. It is just because of SCADE that swift can step into cross-platform development. Swift will be delivering a native-like experience to the Android application by integrating the SCADE SDK.

Here are some of the things needed to develop Android apps with Swift.

• Getting Feature completeness.
• Usability and productivity enhanced.
• Better communication with developers community of Swift language.

Cross-platform app development is quite in demand and why not? It offers speedy development at a reduced cost. There are certain limitations but the benefits are worth it. The SCADE SDK makes possible for the iOS developers to get access to the Eclipse-based integrated development environment like a visual UI designer and code wizard. To get an efficient start to the Android project with Swift, SCADE also provides simulator along with Swift foundation framework.

The software development kit also provides the options of native controls for a specific app development platform to give the app native look and feel for user convenience. These options include map control, web control, and visuals like camera control. All of these options can be easily accessed through simple and single Swift API.

The developers of both platforms need to have adequate knowledge about such a possibility. There has been an immense amount of competition among different app development companies and lack of knowledge can drive the customers away. Customers have immense knowledge of the market these days and not being able to deliver what they expect creates a negative impact.

So, even if you are an individual developer or agency housing developers, you need to provide iOS training with Swift to stay competitive and ready.

Here are some extra things developers can try to build apps that support varied platforms.

• Android simulator ARM
• OSX making use of extra speedy SCADE simulator
• iOS simulator & Binary
• Android ARM and x86 binary (32 bit and 64-bit support)

The SDK will also support Auto-layout which will simplify the process of designing user interface on both Android and iOS platforms. Not just that, it will also open the opportunity to integrate third-party frameworks like C libraries, CryptoSwift, and SQLite.

The iOS developers are now empowered to create apps for another platform without having to use frameworks like Flutter or React Native. This would make Swift a mandatory choice for the developers to learn and there will be a shift towards Apple’s programming language. The industry rival Google cannot let that happen and is making an equal contribution to stay in the competition. Just like SCADE came up with the idea of Swift for Android apps, OpenJDK is preparing to use Java for iOS app development. Let’s see what opportunities it brings for the developers.
