WHAT IS AN ANDROID PHONE?

Android is an open source and Linux-based Operating System for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies.

Android offers a unified approach to application development for mobile devices which means developers need only develop for Android, and their applications should be able to run on different devices powered by Android.

The first beta version of the Android Software Development Kit (SDK) was released by Google in 2007 where as the first commercial version, Android 1.0, was released in September 2008.

On June 27, 2012, at the Google I/O conference, Google announced the next Android version, 4.1 Jelly Bean. Jelly Bean is an incremental update, with the primary aim of improving the user interface, both in terms of functionality and performance.

The source code for Android is available under free and open source software licenses. Google publishes most of the code under the Apache License version 2.0 and the rest, Linux kernel changes, under the GNU General Public License version 2.

Why Android

An Android phone is a powerful, high-tech smartphone that runs on the Android operating system (OS) developed by Google and is used by a variety of mobile phone manufacturers.

Pick an Android mobile phone and you can choose from hundreds of great applications and multitask with ease.

You’ll also get regular software updates that add great new features to your smartphone.

Android is a mobile operating system based on a modified version of the Linux kernel and other open source software, designed primarily for touchscreen mobile devices such as smartphones and tablets.

Which handsets run Android?

The Android operating system is developed and owned by Google.

However, it’s not exclusive to the Google Branded Nexus range of phones.

In fact, Android powers a host of handsets from some of the biggest mobile manufacturers.

These include HTC,Samsung,Motorola and LG are many of whom have enjoyed tremendous critical and commercial success with mobile phones running the Android operating system.

Who makes the best Android phones and tablet phones?

phones to buy

To a certain extent, this is largely a matter of opinion.

However, it is definitely worth noting that both HTC and Samsung’s Android phones have been very favourably reviewed and have sold millions of units worldwide.\\\\\\\\ \compare Samsung Phones with Uswitch today.

Android Applications

Android applications are usually developed in the Java language using the Android Software Development Kit.

Once developed, Android applications can be packaged easily and sold out either through a store such as Google PlaySlideMEOpera Mobile StoreMobangoF-droid and the Amazon Appstore.

Android powers hundreds of millions of mobile devices in more than 190 countries around the world. It’s the largest installed base of any mobile platform and growing fast. Every day more than 1 million new Android devices are activated worldwide.

This tutorial has been written with an aim to teach you how to develop and package Android application. We will start from environment setup for Android application programming and then drill down to look into various aspects of Android applications.

WHAT ARE TABLET PHONES?

What are tablets phones?

Image result for WHAT ARE TABLET  PHONES?

A tablet is a wireless, portable personal computer with a touchscreen interface. The tablet form factor is typically smaller than a notebook computer, but larger than a smartphone. The idea of tablet computing is generally credited to Alan Kay of Xerox, who sketched out the idea in 1971.

FEATURESOF TABLET PHONES

Most tablets are touch operated and are between the size of a smartphone and a laptop. Generally, the device will come with a built-in keyboard that displays on screen and a “tilt” feature that changes the orientation of the display depending on how the device is being held.

What are the main features of the tablet device?

In general, most tablets contain the following hardware components:

  • a processor, generally underclocked to limit heat output.
  • memory chips.
  • a storage chip and possibly a slot for additional storage.
  • a battery.
  • a graphics processor.
  • a sound processor and speakers.
  • sensors such as accelerometers, a compass and light sensors.

How-To-Enable-Usb-Debugging-Mode-For-Android-Phones-And-Tablets

WHAT IS USB DEBUGGING MODE?

USB Debugging is a way for an Android device to communicate with the Android SDK (Software Developer Kit) over a USB connection. It allows an Android device to receive commands, files, and the like from the PC, and allows the PC to pull crucial information like log files from the Android device. And all you have to do is tick a button to make it happen. Neat, right?

Basically, leaving USB debugging enabled keeps the device exposed when it’s plugged in over USB. Under most circumstances, this isn’t a problem—if you’re plugging the phone into your personal computer or you have the intention of using the debugging bridge, then it makes sense to leave it enabled all the time. The problem comes into play if you need to plug your phone into an unfamiliar USB port—like a public charging station. In theory, if someone had access to the charging station, they could use USB debugging to effectively steal private information from the device, or push some sort of malware onto it.

The good news is that Google has a built-in safety net here: per-PC authorization for USB Debugging access. When you plug the Android device into a new PC, it will prompt you to approve a USB debugging connection. If you deny access, the connection is never opened. It’s a great failsafe, but users who may not know what it is may just approve the connection all willy-nilly, which is a bad thing.

Advantages of Turning On Android USB Debugging Mode

Turning on USB debugging mode also helps you check the logs on the Android device to debug various errors. Apart from transferring the files between device and your system, debugging or developer mode also helps you copy any of the APKs to the device
