Android is the world’s most popular mobile OS in the mobile market. From phones and watches to cars and TVs, customise your digital life with Android. Many companies preferred Android to begin mobile application development, or entering to the mobile development market because it has a lower cost barrier than iOS.
Android is an open source software stack for a wide range of mobile devices and a corresponding open source project led by Google. The Android Open Source Project (AOSP) repository offer the information and source code you need to create custom variants of the Android stack, port devices and accessories to the Android platform, and ensure your devices meet compatibility requirements.
Now, it’s time to find and hire a developer to turn your creative and amazing ideas into a tangible app. Here’s a look at what Android developers do so you’re prepared to hire the best one for your Android project.
An Android Developer designs and builds advanced applications for the Android platform and has a solid understanding of the full mobile development life-cycle. Through their creations they give the companies they work for the best opportunity to reach users and make an impact worldwide.
An Android developer is in charge of developing applications for devices powered by the Android operating system. They have a strong understanding of the patterns and practices that revolve around such platform. Moreover, they ensure the best possible performance, quality, and responsiveness of the application.
An Android developer takes project specifications and turns them into a tangible application that can be submitted and published in the Google Play store. Most mobile app projects have a design phase, a development phase, and a submission process. Many Android app developers are “full stack,” handling both design, UI and app coding, but you may choose to have both a designer and a programmer on your app’s development team. Just note that UX (user experience) and UI (user interface) design are two different skill sets that are important for the success of your project. If you decide to hire separate contractors for each component, you need one for UX and one for UI.
Android developer skills are separated into three levels depending on their experience. Developers start at the junior phase for the first few years, although the number of apps they’ve developed and the apps’ complexity are far more important when you determine the right developer for your project. After working alongside more experienced developers, they move to the intermediate phase where they can work on more projects independently. After several years working with complex Android applications, a developer is considered senior level. A senior developer can not only code a project, but they can also make decisions about how to design products. All Android developers should be familiar with:
The developer you need will be determined by your project requirements. If you’re creating a new app from scratch, you’ll need a senior-level developer with the experience to take the project from the beginning and see it through to completion. Junior and intermediate level developers are beneficial for small changes, but a senior developer should review the code before it’s put into production.
To find the right freelance developer, you need to write the project with as much detail and documentation as possible. This could be better for developer to choose the right track to start the work. Android Studio makes it easy to create Android apps for various form factors, such as handsets, tablets, TV, and Wear devices.
This article shows you how to start a new Android app project or import an existing project with your developer. Two major things to learn before start to work on the project.
Define your criteria. What kind of freelance developer you need (Junior or Senior) This enables you to describe the tasks to be done with runtime alerts and notification using the Toogit Project Management Tool, this gives you some direction on development level.
Next, Evaluate what type of challenges freelance android developer may face. This evaluation is most important to write the timeline for your project.
Toogit have more experienced android developers. They should guide and develop your project with a professional way. Always remember that more experienced Freelance Android developers on Toogit may charge more even for simple requirements. If you don’t have any understanding of the development process, it might be better to stick with a senior-level developer. A senior-level developer can help guide you through the process.
If you have a smaller budget and simple bug fixes or additions, you can specify that you need a junior-level or intermediate-level developer, but remember that they may not have the skill set to see a larger project through to completion.
The final aspect of your project to mention is its duration (time and cost) it will take to complete. Android development projects can take a week, a month, six months, or more. The duration is often determined by the developer based on your project description, but you can at least provide an estimate or a deadline, if applicable.
Once you get an estimate of how long the project will take, work with your developer to break down the project into releases if you have a flat-rate cost estimate. You can break the project into phases and ask for specific deliverables by particular deadlines.
Example phases include the following deliverables:
How you can write a brief and attractive Android Mobile Application Job description and post it for free? This guide will help you. The way you write a description will determine the quality of developer that you’ll attract. It’s important to write a detailed desciription of job which helps to build the top android the developer interaction in your project and they submit proposals with fairly accurate cost and time estimates on Toogit.
The title of your project description can include the type of development that you need. You know that you need an Freelance Android developer, but do you need a designer and a programmer? Do you need someone who understands a specific framework and the latest versions of android? The title should pull best Freelance Android developers with a specific skill set.
Next, What type of application do you want developed (gaming, educational, entertainment, etc.)? If you have documentation / excel / slides / pdfs or referrence URLs that shows basic wireframes or ideas, you can include these in your project description. Describe the project in simple and straight way with key points & modules it gives a developer a good sense of the work to be done. If you need the developer to sign an agreement, you can also specify this requirement in your description.
Part of your description should also define the deliverables including any designs, APIs, and full source code that can be uploaded to the Google Play Store. The source code is usually delivered using a version control solution such as Git, and then it can be uploaded to Google Play. You might not know the skill set level that you need, but being descriptive will help providers determine if they have the right experience for your project.
Below is a sample of how a project description may appear.
Project Title:
Android Developer for Online Hotel Booking App
Description:
We are looking for an Android developer to design and program a hote booking app. We have ideas and documentation included in this job post, but we require a developer, designer to paint the design into a workable hotel booking app.
The perfect developer will provide us with the .apk that we can upload to Google Play (Store). All source code, assets, databases, and design will be transferred after the project is complete. We expect the project to be divided into phases/releases where the first phase includes design and assets. The 2nd phase is the development (coding), and the final phase is testing.
The estimated duration of this project is six months. We need the completed hotel booking app by <your target date>
Nowadays, Android is not just on tens of thousands of different phones and tablets. It’s on your wrist, in your living room, in your car, and as soon we start assigning IP addresses to inanimate objects, it is going to be pretty much everywhere around us. A lot of ground for even an experienced Android developer to cover!
Also there are over one million apps on Google Play, not counting Amazon AppStore or markets we are not generally interested in.
So, how can an independent developer create a successful app in this huge market with big players? I have no idea, I haven’t made a successful app! But, I have made a cute one, and I’d like to share my story with you.
The reason of this article, is to list helpful tips, tricks, shortcuts and resources for Android Studio that will improve your overall efficiency and performance.
1.Material Colors theme for Android Logcat
To change Android Studio Logcat you need to go to:Preferences (Settings on Windows / Linux machines) → Editor → Colors & Fonts → Android Logcat and change the foreground color for every type of log.
2. Prevent Android Studio Logcat from clearing the log for the current application when it crashes.
To do that you need to go to theAndroid Monitorpanel and chooseEdit filter configurationon the right side dropdown.
3. Apply a proper code style to your IDE (IntelliJ / Android Studio).
Go toPreferences → Code Style → Javaand in aSchemedropdown you can choose your code style (or set up a new one).
2 styles which are especially worth to mention:
Square Java Code Styles with Android
4. Use split screen for increasing efficiency.
To turn this feature on, you need to right mouse click on the tab of your main screen and choose Split Vertically / Horizontally feature.
But to be as efficient as possible we need to set up a custom keyboard’s shortcut. To do that go to Preferences → Keymap and search for Split Vertically. Then open a context menu and click Add Keyboard Shortcut.
It is shown on a gif below. You can define the shortcut for a horizontal split view as well.
5. Distraction Free Mode.
You can enable it by going to: View → Enter Distraction Free Mode
6. Use Live Templates
you can use many already defined templates, like for Toasts or if conditions.
you can use your own custom templates. Here is a great reference article by Reto Meier. You can also refer to the IntelliJ IDEA documentation.
Learn XML And Java
Extensible markup language (XML) is a markup language that’s the foundation for the Android user interface (UI) and elements. Java is the back-end coding language of the Android platform, and it’s used with binding functionality with your XML layouts. Let’s take a look at a small example.
<?xml version="1.0" encoding="utf-8"?> <layout xmlns:android=http://schemas.android.com/apk/res/android"> <data> <variable name="user" type="com.example.User"/> </data> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{user.firstName}"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{user.lastName}"/> </LinearLayout> </layout>
This small layout has one data object defined as “User.” For developers used to binding elements in even web design, this should be intuitive for you. The data element is defined in Java, and then the object data is bound to the front-end layout element. In this example, we have a first and last name. The following Java code is an example of a User class used for the binding.
public class User { public final String firstName; public final String lastName; public User (String firstName, String lastName){ this.firstName = firstName; this.lastName = lastName; } }
Notice that the constructor takes a first and last name variable and binds the data to the public class properties. When the screen opens on the device, this data is then bound to the front-end elements.
Before you get started in Android Application development, you should be expert in both of these technologies. Understanding the fundamentals of XML formats is relatively easy, but Java is an object-oriented language and object-oriented programming (OOP) can be challenging if you’re not familiar with the concept. A newer language and framework, Kotlin, has been introduced to help advance Android app development. It can also be used with legacy Java apps as Kotlin co-operates with Java code.
The best way to learn Java is to dive into someone else’s code. GitHub is filled with open-source projects that help you understand Java and OOP concepts. The better your OOP skills are, the easier it will be to create a better coded, less buggy Android app.
Mobile devices don’t have the high memory limitations that desktops have. In mobile programming, you must learn to code with smaller memory limitations in mind. If you carelessly use memory on an Android device, you run the risk of your app crashing due to “out of memory” errors.
To work around this, use services on the device sparingly and release memory resources when your app is hidden. You can release memory resources by overriding the onTrimMemory event although you should know that this isn’t a magic solution that allows you to ignore other performance optimization throughout your code. The following is a small sample of pseudocode that shows you how to override the event.
@Override public void onTrimMemory(int level) { if (level >= TRIM_MEMORY_MODERATE) {
//release resources here } }
Google also recommends that you avoid or at least reduce the use of bitmaps to lower the memory use when your app is running on the device.
The Emulator in Android Studio is good for development and even debugging, but it doesn’t fully simulate a working Android device. You can consider basic environment features with the Emulator, but when it comes to testing, you should always use actual devices.
Of course, this is a huge investment for an Android developer, but it will make the entire development and testing life cycle much more efficient. It also ensures that you’re able to test your applications in various conditions as the user changes settings on the actual device. You can, however, use automated cloud solutions such as Amazon’s Testing platform.
Testing should never be taken lightly. It should be a major part when you design and deploy apps for your clients. Fewer bugs means happier users, and it can also mean a more successful app in Google Play. This doesn’t mean that you need to buy every device on the market to test your app on, but you should account for some of the more popular ones and the most common screen sizes.
Java is everywhere, in laptops, scientific supercomputers, gaming consoles, mobile phones, etc. Java is in all platforms and devices and in all countries around the world. It allows developers to make programs work just about anywhere. And it inspired the evolution of an incredible technology community. The brilliance of Java is that the platform independence. Java is simple to use, easy to write, compile, debug, and learn as compared to alternative programming languages. It also allows you to create reusable code and standard programs.
Java is a technology that constantly adapts to new needs these days, there’s a new release each six months or so. The most effective jobs go to Java developers who keep up with the constantly changing language and enhance their skill sets with complementary technologies.
Today, Java is the most popular choice for writing android apps. It’s also widely used in cloud applications, machine-learning environments, and internet of Things technology, Java developers need a wide range of skills, from a thorough information of the basics to an understanding of the latest developments. Java developers creates mobile apps, redesign the user experience on your public website, or keep business-critical applications on the cutting edge, everyone needs code; demand for Java developers is great. Banks and financial sector, automation systems, and other very big industrial sectors are writing their server apps for a long time in java and it will not even fade away soon.
Developing software takes time and planning. Before you start the development process, you’ll need to decide on the skills you need to induce your project off the ground. Most developers can have a grasp of the fundamentals associated with Java if it’s their primary programming language. However you'll be round-faced with those who’ll try and pass off theoretical information as practical experience.
There is a vast difference between the knowledge of a language and the practical application. Simply because a developer will explain a process doesn’t necessarily mean they can code a solution.
