Android Technology Using Linux.

Android is a form of Linux, so it should be no surprise that any modern Android device can run a full-fledged Web server complete with a mySQL database, PHP support and FTP for file transfers. You can even make the server available on the Internet and use it with a domain of your choice. Developers can use an Android Web server to test out their code and then show it to clients or stakeholders in the office. Users who want to run a small blog or share files with co-workers via FTP can have a server sitting in their living rooms or even in their pockets. If you use a $45 Android Mini PC like the MK808B instead of a phone, you can run a server the size of a flash drive that gets all of its power over USB.If you want to write an iPhone app, you’ll be doing all your coding on a Mac. If you want to code for Windows Phone or BlackBerry, you’ll be writing those applications on your desktop or laptop also. However, with Android, you can actually write, compile and test an app directly on your device. Granted, most programmers will want to do their work on a PC, but if you want to tap out some code on the phone itself, a free app called AIDE provides a complete end-to-end solution. You can also write HTML, PHP, JavaScript and other Web code using DroidEdit.Want to see and access the content and apps on your phone from your PC? With a remote access app installed, you can control your phone from a Web browser on your desktop. You can also use such as remote desktop apps such as 2X or Splash top 2 Remote Desktop to control your PC from your phone. Earlier this year, I was impressed when I saw that Samsung’s Galaxy S4 came with an app that measures how many steps you’ve walked each day. However, there’s no special hardware inside the GS4 and, as it turns out, you can use any Android phone as a pedometer. Pedometer apps such as Accused use your phone’s accelerometer to determine when you’ve taken a step and then store that data, along with information you’ve entered about your weight and height, to determine how many calories you’ve burned. You’re finally eligible for a phone upgrade, but now that you’ve gotten that shiny new quad-core super phone, what do you do with your 2011-era handset? You could leave it in a drawer gathering dust, pass it off to your mom or sell it. But if that device runs Android, you could also turn it into a security camera you can use to monitor the nanny or keep an eye on the cats while you’re away from home. You can access the feed over the Internet, right from your new phone. Every Android phone has a microbus port that you can use for charging or copying files to and from your PC. However, most users don’t know that, using a simple USB OTG (“on the go”) adapter cable, a free app and root-level access to the operating system, you can attach can transfer files directly from a USB flash drive or hard drive. You can even attach an SD Card reader and use that to grab photos from your camera and automatically upload them to the cloud. No PC required. With a $3 USB OTG cable, your phone can not only interface with storage ports, but also interface with an external mouse and keyboard. On its own, your phone emits enough powerto connect a typical wired or wireless 2.4-GHz mouse. However, if you want to connect a keyboard as well, you’ll need to route your connection through a powered USB hub. While some Android phones, including the Samsung Galaxy S4, allow you to swap batteries and even purchase high-capacity replacements, many leading handsets, including HTC’s and Google’s flagship devices, have sealed backs. Fortunately, if you have rooted your phone, you may be able to adjust its CPU frequency and voltage, a process known as undervaluing. When we undervalued an HTC One and Nexus 4, we got 72 and 105 additional minutes of endurance respectively.
