The top categories are:-  ● Music  ● Weather  ● Sports  ● Reference  ● Travel  ● Utilities  ● Business  ● Multimedia  ● Social Media  ● Food & Drink  ● News  ● Books  ● Lifestyle  ● Navigation  ● Finance      ●History of Android  The history and versions of Android are interesting to know. The code names of                             from A to J currently, such as Aestro, Blender, Cupcake, Donut, Eclair, Froyo,                           Gingerbread, Honeycomb, Ice Cream Sandwitch, Jelly Bean, KitKat and Lollipop.                     Let's understand the android history in a sequence.  ➢ Initially, Andy Rubin founded Android Incorporation in Palo Alto, California,                     the United States in October 2003.  ➢ In 17th August 2005, Google acquired Android Incorporation. Since then, it is                         in the subsidiary of Google Incorporation.  ➢ The key employees of Android Incorporation are Andy Rubin, Rich Miner,                       Chris White and Nick Sears. 

5. ➢ Originally intended for the camera but shifted to smartphones later because                       of the low market for the camera only.  ➢ Android is the nickname of Andy Rubin given by coworkers because of his                           love for robots.  ➢ In 2007, Google announces the development of the Android OS.  ➢ In 2008, HTC launched its first Android mobile.    ●Android Versions, Codename and API    Let's see the Android versions, codenames and API Level provided                     by Google.    Version  Code Name  API Level  1.5  Cupcake  3  1.6  Donut  4  2.1  Eclair  7  2.2  Froyo  8  2.3  Gingerbread  9 and 10  3.1 and 3.3  Honeycomb  12 and 13  4.0  Ice Cream Sandwitch  15  4.1, 4.2 and 4.3   Jelly Bean  16, 17 and 18  4.4  KitKat  19  5.0  Lollipop  21  6.0  Marshmallow  23  7.0  Nougat  24-25  8.0  Oreo  26-27     

6. ●Android - Application Components  Application components are the essential building blocks of an Android application.                       These   components   are   loosely   coupled   by   the   application   manifest   file   AndroidManifest.xml that describes each component of the application and how                     they interact.  There are following four main components that can be used within an Android                           application −    Sr. No.  Components & Description  Activities  1  They dictate the UI and handle the user interaction to the  smartphone screen.  Services  2  They handle background processing associated with an application.  Broadcast Receivers  3  They handle communication between Android OS and applications.  Content Providers  4  They handle data and database management issues.    Activities  An activity represents a single screen with a user interface,in-short Activity                       performs actions on the screen. For example, an email application might have one                           activity that shows a list of new emails, another activity to compose an email, and                               another activity for reading emails. If an application has more than one activity,                           then one of them should be marked as the activity that is presented when the                               application is launched.  An activity is implemented as a subclass of Activity class as follows −    public class​​MainActivity​​extends​​Activity​​{  }   

7. Services  A service is a component that runs in the background to perform long-running                           operations. For example, a service might play music in the background while the                           user is in a different application, or it might fetch data over the network without                               blocking user interaction with an activity.  A service is implemented as a subclass of Service class as follows −    public class​​MyService​​extends​​Service​​{  }    Additional Components    There are additional components which will be used in the construction of                         above-mentioned entities, their logic, and wiring between them. These components                     are −    Sr.No  Components & Description  Fragments  1  Represents a portion of the user interface in an Activity.  Views  2  UI elements that are drawn on-screen including buttons, lists forms etc.  Layouts  3  View hierarchies that control screen format and appearance of the  views.  Intents  4  Messages wiring components together.  Resources  5  External elements, such as strings, constants and drawable pictures.  Manifest  6  Configuration file for the application.

It replaced – or should we say it                               eclipsed? – ​Eclipse Android Development Tools (ADT) as the primary IDE for native Android app development.                            Android Studio provides code editing, debugging, and testing tools all within an                         easy-to-use drag-and-drop interface. It is free to download and is supported not                         only by Google but also by a large and actively engaged community of Android                             developers. 

9. 2. ADB (Android Debug Bridge)  Android Studio includes the Android Debug Bridge, which is a command-line tool or                           “bridge” of communication between Android devices and other computers that can                       be used during development and the overall debugging and QA process.  By connecting an Android device to the development PC and entering a series of                             terminal commands, a developer is able to make modifications as needed to both                           devices.    3. AVD Manager  Another useful feature of Android Studio is the AVD Manager, the short form for                             Android Virtual Device. The AVD Manager is an emulator used to run Android apps                             on a computer. This allows developers the ability to work with all types of Android                               devices to test responsiveness and performance on different versions, screen sizes,                       and resolutions.    4. Eclipse  As we mentioned above, there was Eclipse before there was Android Studio. For a                             long time, Eclipse was the officially preferred IDE for all Android application                         development.  Even though Google no longer offers support for Eclipse, many developers still use it                             to create Android and other cross-platform apps, as it works very well with many                             different programming languages.    5. Fabric  Fabric is the development platform behind Twitter’s mobile application. It gives                       developers the ability to build better mobile apps by providing them with a suite of                               “kits” that they can pick and choose from. These kits include everything from                           beta-testing to marketing and advertising tools.  Google purchased Fabric from Twitter in January of 2017. Uber, Spotify, Square,                         Groupon, Yelp, and more big-name companies have utilized Fabric in developing                       their mobile applications. 

10. 6. Flow Up  FlowUp allows you to monitor the performance of all your production apps. Handy                           dashboards let you keep track of your stats and metrics, including CPU and disk                             usage, memory usage, frames per second, bandwidth, and more.  flow up is a monthly subscription-based SaaS solution with pricing determined by                         the total number of users in the company.    Click here to learn more above tools Android development  Install Android tools, Describe in this video link click here    Top 13 Learning Android Programming  Here are some of the key concepts you should keep in mind while purchasing                             books for android development which would attain as well as enhance your                         knowledge:    1.
