How To Build A Mobile App Using Phonegap

Web development, programming languages, Software testing & others

All the program developers who want to access their websites online and offline can use this useful guide. It provides you with a simple process of app building with the help of PhoneGap. So if you are looking to develop a new user-friendly mobile application, read on.

What are the Things Required?

In order to develop an app using Phonegap, the first and foremost requirement is knowledge of HTML, CSS, and JScript. This will help in designing a website where you can install the Application. Other than that, no programming is needed to make use of PhoneGap.

Starting with the Procedure

Phonegap is vital and widely used software to develop application software. The programs get a framework that helps in their task by using standard web APIs. You can build the app on all Operating Systems. Furthermore, you can download the software for free. You need to apply your HTML, CSS, and JavaScript knowledge and leave the rest to Phonegap. It will help provide a sophisticated look to the app and keep an eye on the portability of the different operating systems.

With the help of PhoneGap, you can develop mobile apps for all the major Operating systems, whether for Android, Apple iOS, Windows, or Blackberry. You do not need to be an expert or have a sound knowledge of all these OS. Nor do you have to know anything about programming to code the app from the beginning. The task becomes much easier over here. All you need to do is upload the data or information onto the website, which will automatically convert it into different App files.

However, to build an app for any Operating System online, first, you must create a basic setup so that app development becomes easy. Although you can make the app using offline tools such as the Cordova command line interface and the Github repository procedure, it is better to opt for the simple process. Since PhoneGap supports HTML, CSS, and JavaScript, you have to choose these technologies.

Building App for Android Operating System

If you want to build an app for the Android Operating System, it has to be made sure that the device will support the applications which are installed outside the Google Play Store. Just follow the following procedure

Go to the Settings.

Open the PhoneGap security page and then allow applications from Unknown Sources.

In case you want to sell your created mobile application on the Google Play store, you will have to sign a certificate which will be submitted to the Android Market. However, the testing process is not that easy.

Apple iOS

If you are trying to develop an app using PhoneGap for Apple iOS mobile, then the first requirement is a developer account. You will have to buy it, which will cost you around $99 annually. However, you must wait for a day or a couple of days because the account will be reviewed before Apple approves. But if you don’t have an account, it will delay the testing process. Once you get the account, you need to create a profile on a provisional basis and then sign the certificate. This is quite simple. You need to follow the instructions.

PhoneGap For Windows

If you are trying to develop an app for a Windows Operating System, the process is quite complex compared to Android and Apple iOS. Here you have to make use of the latest Windows Installer. Then come across PhoneGap Desktop Setup Wizard. Complete the process and proceed to the installation of the PhoneGap Developer App.

One should keep in mind that any mobile app should have the following features:

Configuration files

Icons for Apps

Content

Configuration

The web-based app needs only a single configuration file which is precise enough for configuring the settings. It contains all the required information required to assemble the app. It can be illustrated through the given widgets.

Widgets

The ID is maintained across different app stores.

This is known as the version number of the app. Here x.y.z is the format, and also positive integers such as 1.0.0. It indicates a major-minor-patch version system.

This refers to the app’s name that appears beneath its icon on your mobile screen. Anybody using a mobile can find the app by typing this name.

It describes the app and informs what the app is all about.

As it is evident, it tells about the creator or developer of the app. On most occasions, the user would usually find the name of the company or organization that has launched this app.

The addition of icons to the apps is essential. You can code it in several ways. The .src path informs about the icon image. On the other hand, gap: platform indicates the platform of the Operating System. The gap: qualifier determines the android-operated mobile phones’ density, whereas the iOS uses width and height.

Icons

You already are familiar that the sizes of various mobile phones vary from one another even if they are using the same Operating System. Different mobile phone consumers have other choices regarding the selection of the apps, and so you have to offer all icons of various mobile phones. Another vital factor is to create the shape and size of the icons by the Operating System. To explain the point better, let us illustrate an example-

res/icon/ios Andres/icon/android/drawable-xxxx..

If you want to increase the speed of your task, then better develop a logo sized 1024×1024 and visit the site chúng tôi Through this particular website, you can design logos both for the iOS and Android Operating Systems. As previously mentioned, flagship organizations and individual developers are responsible for building most mobile application software.

As is evident, the most popular and widely used mobile operating systems include-

Windows

Android

BlackBerry

Ios

Also, apart from these, many other operating systems are currently available. All these operating systems are readily available in the market. One can use a graphical representation to explain how to use these features in a mobile application.

Out of all the operating systems, Android is the most popular. One of the benefits is that you can email all the logos in zipping format.

You can copy an offline website to a local hard drive and access it later. You do not need an internet connection to use this offline PhoneGap app, which helps you develop an application that can be accessed on mobile phones. It includes an app with a different collection of stories, short tutorials, or any other offline content. The user can read it all offline.

Offline App

The offline application consists of the PhoneGap folder structure. It has only two files in the root directory.

The chúng tôi comprises app configuration settings, and the chúng tôi consists of a homepage of the web contents. However, it is vital to remember that all links associated with HTML files should have a relative path. There is no such absolute path or base tag.

Online App

In the case of the Online App, the data folder is not present. The main reason is all files are present on the actual server, and you can access it through the Internet. You already know that chúng tôi consists of real links containing the web server. Once we have determined the mode of the app and organized its files, the next step is to compress the files using a standard zip tool and save them.

Signing your App

The web developers or the concerned organization must sign an app and maintain the order. This is why you have to sign the app. The key tool, a part of Java distribution, is an essential requirement here.

The following command will help in the generation of the my_keystore-PhoneGap Keystore file:

keytool-genkey-v-keystore my_keystore.keystore-alias TutorialsPoint -keyalg RSA -keysize 2048 -validity 10000

How to Make Adobe ID?

To create an ID, you have to follow the easy steps-

All operating systems, excluding the one for which you are developing the app, will fail to process further as you haven’t given a signed key.

However, before we upload the app, we must thoroughly test it on virtual or real devices.
