What is the Best Open Source Software to Create an App?

PhoneGap is the most popular open-source software to develop an application and has been downloaded by thousands of developers millions of times. The software can be installed from mobile app stores and directories. This software works with the Apache Software Foundation (ASF) so it will always stay open source and free under the Apache License, Version 2.0.

While you are planning to build applications for platforms- Android, iPhone, Window, and other different platforms, PhoneGap can solve this by utilizing standard web technologies to link web applications and mobile devices.

Understanding the PhoneGap

Understand the PhoneGap in short; it is an application container technology which helps a software development company in creating pre-installed native applications for mobile implementing HTML, CSS, and JavaScript code. The framework is 100% open-source under the Apache Cordova project. We are discussing some standard services thoroughly you could know the PhoneGap deeply-

PhoneGap API

PhoneGap offers an API (application programming interface) that enables you for approaching native operating system implementing JavaScript. You can create your application logic with the help of JavaScript code and the API can handle communication with the native operating system. Moreover, you can take benefits of the JavaScript-to-native communication process to customize native plugins in PhoneGap. The Native plugins will allow you to construct your own classes and equivalent JS interfaces for utilizing within PhoneGap applications.

PhoneGap UI

PhoneGap user interface is made using CSS, HTML, and JavaScript. The UI layer of a PhoneGap application is known as a web browser view that assumes 100% width and height of the device. You can construct your application with navigational, interactive, content elements, and applications chrome using HTML, CSS based UI.

The PhoneGap web view is the same that is utilized by the native operating system. On iOS platform, this is known as the Objective-C UIWebView class and on Android platform, this is recognized as android.webkit.WebView. So, there are many disparities in the web view rendering engines between operating system.

PhoneGap Application Distribution

As the PhoneGap applications are created in HTML, CSS, and JavaScript code the finishing step is binary application archive that can be distributed throughout standard application ecosystems. Have a look at the given points-

The output for iOS applications is an IPA file, also known as iOS Application Archive.
For Android, the output is an APK file, also considered as Android Package.
The output for Window application comes as a XAP file which also known as Application package.

These same application package systems are utilized by Native application and also can be shared throughout the suitable networks like- Amazon market, BlackBerry App World, Window mobile devices market, Android and iOS market etc.

PhoneGap Application Architecture

Specific application developers are going to change on a case-by-case base, but most data-driven applications utilize the following basic architecture-

The PhoneGap application works as a client for the customers to cooperate with.
The PhoneGap client makes contact with an application server to obtain data.
The application server manages business logic and makes connection with a back-end data warehouse.

PhoneGap can work with any application server utilizing standard web protocols. The server works on business logic and calculations, and usually recovers or endures data from a separate data store – this is generally considered as a relational database, but could be any arrangement or method for data determination.

PhoneGap Plugin Library

We are discussing some PhoneGap plugins that can be used in application development for multiple platforms.

Cordova-Plugin-urlhandler

It can be performed on Android, iOS, and Window platforms.

Installation code

<a href="mycoolapp: //?foo=bar">Open my app</a>

These all email will work properly while you are launching your application linking with.
