How To Build Your First PHP for Android Application

Google’s open source Android mobile operating system is taking the smartphone market by storm. Unlike Apple, which has stringent guidelines and requirements for developers who want to offer their applications on the iPhone App Store, Google has left the Android platform wide open. You can even write Android applications in PHP now. The folks at Irontech have created a PHP port to run on Android, and with the Scripting Layer for Android (SL4A), you can build PHP Android applications.

In this article, I’ll explain how to install, set up and use PHP for Android and SL4A, I’ll present a demo application as an example, and I’ll give a first-hand account of the PHP for Android developer experience.



Installing PHP for Android

To install PHP for Android, you have to have a phone or emulator running Android version 1.5 or higher and you must enable “Unknown Sources” under Application settings. After you have that set, you simply install the SL4A environment and the PHP for Android APK.

Installing the SL4A is straightforward, but after you install the PHP for Android application, you need then click “install” again for it to be fully installed and functioning. If you have trouble with the installation, there’s a handy video demonstration available on Vimeo to walk you through the process.

What is PHP


PHP is an open-source, interpreted, and object-oriented scripting language that can be executed at the server-side. PHP is well suited for web development. Therefore, it is used to develop web applications (an application that executes on the server and generates the dynamic page.).

  • PHP was created by Rasmus Lerdorf in 1994 but appeared in the market in 1995. PHP 7.4.0 is the latest version of PHP, which was released on 28 November. Some important points need to be noticed about PHP are as followed:
  • PHP stands for Hypertext Preprocessor.
  • PHP is an interpreted language, i.e., there is no need for compilation.
  • PHP is faster than other scripting languages, for example, ASP and JSP.
  • PHP is a server-side scripting language, which is used to manage the dynamic content of the website.
  • PHP can be embedded into HTML.
  • PHP is an object-oriented language.
  • PHP is an open-source scripting language.
  • PHP is simple and easy to learn language.

Control:

Different programming languages require long script or code, whereas PHP can do the same work in a few lines of code. It has maximum control over the websites like you can make changes easily whenever you want.

   Basic things about RPA (Robotic Process Automation) Every organization should consider digital automation in order to increase their revenue, lower costs and improve customer experience. RPA – Robotic Process Automation (RPA) is a huge step towards achieving the complete digital transformation goal. RPA uses digital workforce which aims to automate high volume, routine, mundane and repetitive human tasks – with a scalable and reliable army of trained software robots. This helps to utilize human resource into a more value-added work. RPA systems are generally based on artificial intelligence (AI). There are few  RPA Companies in India  which includes VNC technology simplified which aims to provide you the best in the industry. W hy RPA? RPA is one of the fastest growing sectors of the operational technology industry. RPA is real, it is expanding and it can increase your company’s efficiency and productivity leading to benefits that reach directly to the bottom line...

UiPath Introduction Digitalization enables organizations in serving the growing needs of the increased population. But it is associated with different tools and requires a diversified skill set is needed to handle it. Unfortunately, there are minimal human resources available in the market who possess this diversified skill set, and they are not sufficient to address this scarcity problem. To resolve this issue, the entire IT industry needs a solution that could be fast, reliable, and capable enough to solve this problem. And finally, they found a solution to this problem in the form of RPA. UIPath is one of the major RPA tools. Now, let’s start with knowing what RPA is all about. What is Robotic Process Automation? Robotic Process Automation  is software that uses Artificial Intelligence (AI) and machine learning to automate the backend office processor to perform the tasks without human intervention. These tasks could be calculations, queries, maintenance of records, etc. RPA tec...

 Automation software that anyone can use for any business process. What is Robotic Process Automation (RPA)?     R obotic Process Automation (RPA) is software technology that’s easy for anyone to use to automate digital tasks. With RPA, software users create software robots, or “bots”, that can learn, mimic, and then execute rules-based business processes. RPA automation enables users to create bots by observing human digital actions. Show your bots what to do, then let them do the work. Robotic Process Automation software bots can interact with any application or system the same way people do except that RPA bots can operate around the clock, nonstop, much faster and with 100% reliability and precision. What can RPA do for me? Robotic Process Automation bots have the same digital skillset as people—and then some. Think of RPA bots as a Digital Workforce that can interact with any system or application. For example, bots are able to copy-paste, scrape web data, make calc...
