What is Software Development Kit or "SDK"?

A software development toolkit (SDK) is a set of software tools and programs provided by hardware and software vendors that developers can use to build applications for specific platforms. These providers make their SDKs available to help developers easily integrate their apps with their services.

In order to use a SDK, a developer needs an iOS SDK to build iOS apps, an Android toolkit for building Android apps, Nordic SDK to build Bluetooth or wireless apps and a VMware SDK to enable integration with the VMware platform.

Although SDKs are largely associated with native mobile apps, developers can use them in connection with websites, set-top boxes and other digital platforms.

SDKs include documentation, application programming interfaces (APIs), code samples, libraries and processes, as well as guides that developers can use and integrate into their apps. Developers can use SDKs to build and maintain applications without having to write everything from scratch.

Some SDKs are required for developing a platform-specific app. For example, developing Android apps in Java requires the Java Development Kit, iOS apps the iOS SDK, and for Universal Windows Platform the .NET Framework SDK.

All of this is done through the libraries included in each SDK. A library is essentially a piece of software that allows your application to communicate with the specific platform its running on.

Which SDK is required for developing Java apps?

Which SDK is required for developing Java apps for example, the development of an Android app on the Java platform requires a Java Development Kit? For iOS applications (apps) the iOS SDK is required. For Universal Windows Platform the. NET Framework SDK might be used.

What is SDK JavaScript?

The AWS SDK for JavaScript is a collection of software tools for the creation of applications and libraries that use Amazon Web Services (AWS) resources. There are separate software development kits (SDKs) for browser-based or server-side JavaScript application development

More specifically, SDKs include:

Libraries or APIs – pre-defined pieces of code that let developers perform common programming tasks on the platform.
Integrated development environment (IDE) – a visual editor that helps developers design and layout graphical elements, such as text boxes and buttons. These are common in mobile software development toolkits. For instance, Apple’s IDE, Xcode, contains a suite of software development tools to help developers build software for macOS, iOS, iPadOS, watchOS and tvOS. There are numerous IDE options for Android.
Tools to help developers do such tasks as debugging, building, running and testing their applications.

SDKs enable developers to enhance apps with more functionality and let them include push notifications, ads and more. SDKs also help developers more efficiently create new tools and make the process easier because everything is prebuilt.

For example, if a developer wanted to share images or text from his or her app directly into Facebook, he or she could look for Facebook’s Android SDK to find the necessary code that would work for an Android device. This speeds deployment because the developer doesn’t have to write the code from scratch.

Why use SDKs?

Software development toolkits allow developers to add functionality to their applications and enable them to build the standard components of their apps easier and faster. SDKs are usually all-in-one products and don’t need to be integrated with other components, which can slow down the development process.

Typically, developers use SDKs for simple functions, such logging in, location services and mobile payments. However, there are also SDKs that help developers build more complex app features, such as augmented reality (AR) and virtual reality (VR). SDKs reduce complex integrations by simplifying standard processes, such as creating authorization signatures or interpreting SMS messages in native languages or platforms.

Difference between SDKs and APIs

An API is code that enables two software programs to communicate with each other. An API defines the correct way for a developer to request services from an operating system or other application and expose data within different contexts and across multiple channels.

When a developer uses an SDK to develop applications and create systems, those apps have to communicate with other applications. An SDK includes an API to enable that communication.

Other differences include:

SDKs usually contain APIs, but APIs don’t contain SDKs.
Although an API can be used for communication, it can’t be used to create new applications.
SDKs let developers create applications and act as the building blocks for the software product.
APIs allow the function of apps within the parameters of the SDK they are bundled with. APIs are the code that enables clearly defined communication between two separate apps.
An SDK is the tool and component piece of code that has been created for a specific purpose, while an API is just an interface for a service

What is the difference between API and SDK?

While an API is purpose-built to perform a specific function of allowing communication between applications, an SDK is an integrated platform that boasts a set of tools to create these applications. APIs facilitate and allow interaction between applications, but they alone are not enough to create a brand new app.

What is a good reason to use an SDK rather than directly using an API?

One of the largely overseen advantages of SDKs is the ability to have deep integration with a native platform such as Android or iOS to provide end to end integration of services for a more secure overall solution, which can be easy to miss when using APIs

What makes a good SDK?

Ideally, an SDK should include libraries, tools, relevant documentation, samples of code and implementations, process explanations and examples, guides for developer usage, limitation definitions, and any other additional offerings that would facilitate building functions that leverage the API

Which software development kit is required for developing Java apps?

Some SDKs are required for developing a platform-specific app. For example, developing Android apps in Java requires the Java Development Kit, iOS apps the iOS SDK, and for Universal Windows Platform the NET Framework SDK. All of this is done through the libraries included in each SDK

How do you use SDK Tools?

SDK Details

An SDK can take the form of a simple implementation of one or more application programming interfaces (APIs) in the form of on-device libraries to interface to a particular programming language, or it may be as complex as hardware-specific tools that can communicate with a particular embedded system. Common tools include debugging facilities and other utilities, often presented in an integrated development environment (IDE). SDKs may also include sample code and technical notes or other supporting documentation such as tutorials to help clarify points made by the primary reference material.

SDKs often include licenses that make them unsuitable for building software intended to be developed under an incompatible license. For example, a proprietary SDK is generally incompatible with free software development, while a GPL-licensed SDK could be incompatible with proprietary software development, all particularly for legal reasons. However, SDKs built under the GNU Lesser General Public License (LGPL) are typically safe for proprietary development.

The average Android mobile app implements 15.6 separate SDKs, with gaming apps implementing on average 17.5 different SDKs. The most popular SDK categories for Android mobile apps are analytics and advertising.

SDKs can be unsafe (because they are implemented within apps, but yet run separate code). Malicious SDKs (with honest intentions or not) can violate users’ data privacy, damage app performance, or even cause apps to be banned from Google Play or the App Store. New technologies allow app developers to control and monitor client SDKs in real time.

Providers of SDKs for specific systems or subsystems sometimes substitute a more specific term instead of software. For instance, both Microsoft and Citrix provide a driver development kit (DDK) for developing device drivers.

How SDK Functions

Android SDK is free of cost by Google and can be downloaded from the website of Android app developer. Android SDK functions quite similar to the iPhone SDK but can be sound a bit challenging for a novice in basic computer programming. Android SDK has Droid emulators, which let the software developers to experiment the process and functionality of the android application and removing the necessity to load, unload, and reload a part of software oftentimes. Although the SDK comes free of cost, but if the user is not well versed with the technology then it would be clear case time and money loss, so it’s always wise to opt for the services of a professional android app developer. To install it, you need to have Eclipse IDE and JDK installed in the system.

What is Windows SDK used for?

The iOS SDK (Software Development Kit) (formerly iPhone SDK)

Software development kit developed by Apple Inc. The kit allows for the development of mobile apps on Apple’s iOS operating system.

While originally developing iPhone prior to its unveiling in 2007, Apple’s then-CEO Steve Jobs did not intend to let third-party developers build native apps for iOS, instead directing them to make web applications for the Safari web browser. However, backlash from developers prompted the company to reconsider, with Jobs announcing in October 2007 that Apple would have a software development kit available for developers by February 2008. The SDK was released on March 6, 2008.

The SDK is a free download for users of Mac personal computers. It is not available for Microsoft Windows PCs. The SDK contains sets giving developers access to various functions and services of iOS devices, such as hardware and software attributes. It also contains an iPhone simulator to mimic the look and feel of the device on the computer while developing. New versions of the SDK accompany new versions of iOS. In order to test applications, get technical support, and distribute apps through App Store, developers are required to subscribe to the Apple Developer Program.

Combined with XCode, the iOS SDK helps developers write iOS apps using officially supported programming languages, including Swift and Objective-C. Other companies have also created tools that allow for the development of native iOS apps using their respective programming languages.

The iOS SDK is a free download for Mac users. It is not available for Microsoft Windows personal computers. To test the application, get technical support, and distribute applications through App Store, developers are required to subscribe to the Apple Developer Program.
