The rise in mobile device usage is making it difficult for developers to decide whether a business needs both a website and mobile app. Many developers seem to have settled on focusing on developing for a single mobile platform – be it Android, iPhone or any other platform. In essence, a lot of developers favor creating native apps (written for a particular platform). A few others favor developing web apps, as they allow them to write once and can be deployed everywhere. Through this post, I’ll discuss about Developing Android Apps Using HTML5.

A web application is a browser-based application that contains plenty of interactive options like buttons, icons, etc. compared to web pages. In fact, web apps can be used even without Internet connection just like native apps. Some of the best web apps are Twitter,, Facebook and many others. Mobile platforms use native programming languages. For example, Android uses Java, iOS uses Objective-C and so on. On the other hand, web apps are developed using HTML5, JavaScript and CSS3 web technologies.

Now, let’s start learning about Developing Android Apps Using HTML5 here.

Developing a Web App For Android Using HTML5 Technology

Developing an Android-based web application and testing it is similar to developing and testing a web page. First off, you’ll need to use a text editor (such as Notepad or any other) wherein you will have to enter HTML code (such as the one shown below). Once you’ve completed writing the code, save your HTML markup with the name as you like (e.g. mywebapp.html). Next, embed the HTML file into your Android device, and then open it in your browser.

The Basic HTML Source Code:

The default browser of Android devices starting from 1.5 version lets users to access Geolocation and other features. In addition to this, bridges are made available, enabling users to access hardware sensors, camera, etc. When writing code for your web app, you can include several mobile features. Some of the features are listed as below:

Click-to-call: In order to associate the feature “click-to-call” for your telephone numbers within your Android mobile browser, simply add the “tel” attribute to an anchor tag, as follows:

  • User input: You can insert different inputs according to the needs of mobile users. For instance, you can change the keyboard form to make it perfectly-suited for the users using the <input> element. For example, you can display telephone number and email as user input using the following lines of code:
    Contact Number:  <input type=tel>
    Email address:
      <input type=email>
  • Geolocation: Using the W3C API “Geolocation.getCurrentPosition()” feature, you can fetch user’s location.

Using Frameworks for Web Apps Development

Thanks to the availability of mobile app development frameworks, developers can achieve more using less code. Some of the most recommended and popular frameworks that users prefer for developing web applications are Twitter bootstrap, PhoneGap, jQuery mobile, and many others. As an app developer, you should be aware of each framework’s capabilities, prior to initiating any project. These frameworks offer several advantages like rapid development, reduce development time, require minimal testing and much more.

Some Key Recommendations for Designing a Web App

So, now that you have come to know about the ways of developing android apps using html5, it is also important to pay attention to some of the best practices to facilitate enhanced user mobile user experience. Below are a few recommendations, you should keep in your mind when creating a web app design:

  • Make sure your web apps remain functional even when cookies are unavailable.
  • Enable automatic sign-in, so as to avoid prompting a user to enter input on every launch.
  • Avoid using too many redirects.
  • Combine all stylesheets, scripts, images, etc. into one single resource to minimize external resources.
  • Use compressed data transfer rather than network for saving your users time and money.

Wrapping Up!

Here’s hoping that the post will help you learn about the basics of creating a simple web app. Additionally, it will also let you know about other important key aspects of developing a web application you need to be aware of.
