Mobile App Developer @Salary.com

Software developers has an average salary of $68K compared to mobile app $97K in the U.S.A.  It is one of the highest paying job.

Mobile Apple Developer @VisionMobile

There are about 680K mobile developers in North America.  The big three Asia, Europe and North America have the total over two millions (2,200,000) mobile developers.  The industry is hiring a lot of mobile developers world wide.

Mobile App Development flow @cestarcollege.com

To start a mobile app, do some research first.  Next, plans for the time.  How to code?  Which programming language?  How to test using the emulator? Do some testings like user testing.  Publish the app to stores and marketing.

Mobile Architecture

Mobile architecture components are the core libraries, platform API and graphic design.  Apple Xcode is a developer tool to create iPhone app.  It includes the compiler and swift programming language.  The swift programming is based on Objective-C.  iOS application packages are saved in the .ipa.  Android Studio is another developer tool to create mobile app for Android devices with Java and C/C++ programming languages.  Android application packages are saved in the zip file.apk.  Microsoft introduced the Universal Windows Platform for all Windows devices  based on .NET architecture.  Microsoft also invested in Xamarin, a company that created a cross platform for iPhone/Android/Windows. 

Mobile Architecture @Microsoft.com

HTML5, CSS, JavaScript are web programming languages and code shared that the app is using the web service to connect to app server or game server which allows multi players and messaging.  It is difference than a standard or tradition game that the user downloads to the device and plays alone.

iOS Architecture @Apple.com

Cocoa Touch supports the appearing of the screen like the AirDrop Framework which allows to share photos and documents.  The TexKit Framework supports text control.  UIKit Framework supports the behaviors of the objects.  Address Book UI Framework allows to manage contact information.  EvenKit Frameworks allows to add/edit/view calendar events.  GameKit Framework supports gaming.  iAD Framework allows to add advertise banner to the game.  MapKit Frameworks provides map direction for the app.  Message UI Framework provides messaging.  Notification Framwork provides display information.  PushKit Framework alerts incoming call for the app.

Media provides core graphic, audio, and video frameworks. Core Audio Frameworks are a set of frameworks to manage audio.  Core Graphic Frameworks provide graphic.  Core Image Frameworks provide images  Core Text Frameworks provide text layout.  Core Video Frameworks provide video.  Other media frameworks are Game Controller Frameworks, Image I/O Frameworks, Media Accessibility Framework, Media Player Frameworks, Metal Frameworks, OpenAL Framework, OpenGL ES Framework, Photo Frameworks, Photo UI Framework, Quartz Framework, SceneKit Framework and SpriteKit Framework.

Core Services provide system services like iCloud, social media, and networking from the CloudKit Framework, Social Framework, CFNetwork Framework, Core Data Framework, Account Framework, Address Book Framework, AD Support Framework, Core Location Framework, Core Media Framework, Core Motion Framework, Core Telephony Framewor, EvenKit Framework, HealthKit Framework, HomeKit Frameowrk, JavaScript Core Framework, Mobile Core Service Framework, Multi Peer Connectivity Framework, NewstandKit Framework, PassKit Framework, QuickLook Framework, Safari Service Framework, StoreKit Framework, Core Foundation Framework, System Configuration Framework and WebKit. 

Core OS provides Generic Security Services Framework, External Accessory Framework, Local Authentication Framework, Network Extension Frameworks, Security Framework and System drivers

The iOS Architecture @Apple.com

iOS apps are based on Model-View-Control architecture.  In the View, the UIWindow object display the contents, windows, graphic layout, and user interface.  The Controller manages how to display the View.  The UIApplication object in the Controller sends the event or events to the View Controller and to the View.  During the process, the app accesses the data and document from the Model.  Another way to easy understand is View-Control-Model.  It should be called View-Control-Data.  However, the Data has its model.  Anyway, the iOS apps or games are based on Model-View-Control processes. 

Xcode @Apple.com

Xcode 8 is the latest version built-in Swift 3 programming language.  It is a compiler and interface builder.  It requires Apple macOS computer.  It can be downloaded at  https://developer.apple.com/xcode/

Xcode @Apple.com

Open Xcode and choose iOS, there are some templates ready.  Click on Single View Application. 

Xcode @Apple.com

Name the app and the team.  Choose Swift.  Choose the device.  Select Include Unit Tests and Include UI Tests.  If Core Data is used, select Core Data.  Otherwise, leave it blank. 

Xcode @Apple.com

Xcode has four areas: Toolbar tabs with the emulator functions for testing devices, the Navigator area project structure, the Editor area for work space, the Utility area for settings. 

Xcode @Apple.com

The AppDelegate.swift is the source code file.  The actual binary file is the .app file.  The ViewController.swift is another source code file to control the displays.  The Main.storyboard is the interface builder.  The Asseets.xassets contains resource files such as images.  The Test folder contains test activities.  If this is a framework folder, the folder contains plug-in frameworks.  Another folder can be added to store the resource files.  The Products folder contains the executable file .app.  The native project is saved  as the .ipa archive compressed file.  The .ipa file structure contains the .app file, the metadata .plist file, and other app data.  Objective-C programming language uses the .h and .m files for header and object implementation.

Swift language is based on C and Objective-C created by Apple.  Swift includes compiler, standard library, SDK overlay and debugger.  The swift file is the source file.  It takes times to learn the swift programming.  Many open sources and commercial frameworks are available to create mobile app quickly with no code or less coding required.   

Android Architecture @Android.com

Android architecture is built on Linux Kernel.  Android app cores are Android Framework, Android Runtime (Android RunTime ART and DALVIK Virtual Machine), and Native Libraries (Web engine WebKIT, 3D Graphic Libary OPENGL/ES, SQLite database, Secure Sockets Layer SSL,.etc).  Android supports C/C++/Java and allows other run-times plug-in to create C# app, HTML5 and other programming languages.  This means Android is an open source. 

Android Architecture @Android.com

Android 7 is the latest version.  The best feature of version 7 is the multi-windows.

Android Architecture @Xamarin.com

The .NET APIs use Mono runtime because it was written in C language.  The Java APIs use the Android Runtime because the Android Runtime was written in Java language.  Android Architecture supports both environments.    

Android Studio @Android.com

Android Studio cores are Android app modules, Library modules, Google App Engine modules.  Download Android Studio @ https://developer.android.com/studio/index.html

Android Studio

Other than the cores, the other components are the Android SDK Software Development Kit and the Android Virtual Device.  Click Next and Next to complete the installation.  It takes a few minutes for the installation.

Android Studio

Android Studio 2.2.3 is the latest version

Android Studio

Scroll down to select Android 7.1.1

Android Studio

Select Empty Activity to create a blank project.

Android Studio

Name the app and an individual/organization.

Android Studio

Click on the MainActivity and design the app.

Android Studio

Select or create a new virtual device to run the app.

Android Studio

Set the virtual RAM for the simulator.  It is actually used the real computer RAM.

Android Studio

The simulator allows to customize the virtual devices. 

Android Studio

The emulator requires to restart the computer to changes the BIOS setting for the hardware chip to enable virtual technology chip.  Shutdown the computer, power on, press F10 (for most computers) to enter the BIOS.  In the System setting, enable Virtualization Technology, Save and Exit.  Open Android Studio, another screen will pop-up to notify that Android will disable Hyper-V to use the emulator.

An update is required.  It displays on the top right menu or running the emulator.

Run the app, the virtual phone will pop-up.
