What is an SKD?

A Quick Overview of SDKs

The term SDK stands for Software Development Kit that contains tools and utilities for developing software. In essence, SDKs are widely used as a building block for app development.

  • APIs (Application Programming Interfaces)
  • Drivers
  • Runtime Development Environment
  • Libraries
  • Editors
  • Network Protocols
  • Compilers.
  • Code examples
  • Documentation, tutorials, guides, and references.

The Benefits of SDKs

Some of the benefits of SDKs for developers are listed below.

Makes Development Tasks More Manageable

A good SDK offers pre-written codes, instructions, APIs, and many other utilities that increase productivity. Managing app development projects is easier with an SDK.

Reduces Development Costs

Software engineers are often high earners. That is why their engagement must be for the development of high-value codes. With SDKs, developers don’t have to build every single code from scratch as SDK often offers ready-made codes for third-party integration.

Expedites Time to the Market.

Since SDK reduces the App development engineering efforts and enhances productivity, allowing developers can complete app projects quicker. They can also roll out updates faster in response to feedback from app users.

Offers Better User Experience

Some SDKs provide ready-made user interfaces (UIs) and UI elements that elevate user experiences. Sometimes, developers can customize these UI elements to suit their design objectives. In any case, the integrated UI helps elevate the user experience.

Offer Brand Control.

SDKs can play a vital role in controlling how third-party platforms interact with your brand. A company can define the design patterns of its brand to prevent misuse and abuse by third-party applications.

Enhance Security

Security is a paramount feature for any type of app, especially the ones that manage financial transactions. That is why payment processors offer SDKs with enhanced security functions like APIs and 3D authentication.

How SDK Works

SDKs offer in-built elements that enhance mobile and web development tasks. The straightforward procedure for using an SDK is outlined below:

Common Use Cases of SDKs

The use cases of SDKs are numerous and cut across multiple industries. It has been used in implementing projects like analytics, monetization, payments, social media, automation, marketing, CRM, advertisements, communications, and lots more.

SDK Deployment Examples

Here are some specific functions created with SDKs

Push Notifications SDK

In this scenario, SDK is used to expedite the creation of a push notification function in a mobile application. In this example, we shall be considering a smartphone running an Android operating system.

  • Install Android Studio: After installing Android Studio, download and install the Android SDK. You can check this guide to Install SDK on your Android Studio Project.
  • Create a Back4app Account: Create an account at Back4App and create your first app. Take note of the application number, you will need it to connect the SDK, This guide shows you how to build your first app with Back4App.
  • Connect Back4app with Android SDK: the procedure for connecting Back4App with Android SDK is not complex. You need an application ID and a client key to accomplish the task. This guide details the process for connecting Android SDK with Back4app.
  • Connecting Back4app with Firebase: You can use the free notification system of Firebase by connecting it to Back4apps. See this guide on Push Notification Setup to accomplish this task.
  • Test the Push Notification: The final step is to send a test message to see how the push notification setup works. Choose Android on the Back4App dashboard, define your message, choose a target audience, and activate the Send Push-button.

Payment Integration SDK

This section shall be considering how to use SDK for mobile payment integration. We shall be using the Android Operating System in this example.

Advertising SDK

Let’s consider a simple way to monetize an app with SDK.

SDK Licence Types

The use of most SDKs is subject to a license agreement. Therefore, it is necessary to review the licensing agreement before deploying an SDK from a vendor. These licenses are often open-source or proprietary.

  • GPL (General Public License): This licensing schema allows you to deploy, study, share the modify an SDK.
  • Proprietary License: This licensing schema is typical for closed-source and commercial software.
  • LGPL (Lesser General Public License): The GPL, it’s a free license that allows developers to integrate SDK components into their software.

Conclusion

Software Development Kits, commonly called SDKs are a suite of tools used for enhancing web and mobile app development projects. Developers use SDKs to simplify development tasks, and access ready-made development utilities like code libraries, APIs, and code samples.
