Chapter 5: Mobile Application Development, Chapter 5 part 2 - Coggle…

- - - - Too many devices with vastly different hardware specification and capabilities.
    - - Have to support application running on different version of Android at the same time
- - - - Any mobile application development requires the latest release of OS X operating system running on Apple certified devices (iMac, Macbook, etc)
    - - Publishing iOS mobile Application is significantly costly compared to other platforms
- - - - Platform SDK License
      - Development environment
      - 3rd party libraries
      - Application Distribution cost (Google Play Store, iTunes App store, Microsoft App Market)
- - - - Write code only once and use it for all major mobile platforms.
    - - Use plug-in for developing platform
        independent mobile apps
    - - No need to be skilled in highly complicated
        object oriented technologies like C++ and Java
    - - Reduces the operational development time and cost for mobile applications
  - - - Not sync with the current mobile development market
    - - Not allow the external tools and restricts the developers to develop app as they want
    - - Gives a longer code render time while developing apps for multiple platforms
    - - Overall performance of the developed app through cross platform technology shows ineffectiveness
- - - - Open source
      - Use of well-known web technologies
      - Good availability of "plugins"
    - - VERY fragmented
      - Performances are not the best
      - POOR for heavily graphical stuff like 3D or videogames
- - - - Should be located at the bottom of the scrolling
        list, in-line with the rest of the list content
    - - Separate the menu item category
  - - - Cons
        
        Not future proof
        
        Slower experience
      - Pros
        
        Less confusion
        
        Buttons are always there
        
        Doesn’t impact experience
        
        Quick launch
    - - Cons
        
        Extra steps
        
        Take up precious pixels
      - Pros
        
        Future proof
        
        Flexibility on a number of levels
        
        Gestures!
        
        Buttonless is prettier
        
        Immersive experience
  - - - The light status bar, with dark icons, better harmonizes with light content and can be used an alternative to the dark status bar.
    - - By default, the color of the status bar is darker tone
        of the app bar color
  - - - Frequently accessed menu should be represented as
        individual icons
      - Opens the overflow menu, which contains secondary actions and menu items like ‘help’ and ‘settings’
    - - Rarely used menu items should be placed in ‘Overflow
        menu’. Usually represented by the “Three-dots” icon.
      - App-related actions
    - - Can be an app title, page title, or a page filter
      - Reflects the current page
    - - Up arrow for navigating upward through app hierarchy
      - Control to open a Navigation Drawer
- - - - Open additional dialogs from within a dialog
      - Contain scrolling content, particularly alerts.
    - - Inform the user about a situation or action that requires their confirmation or acknowledgment before proceeding
      - Most alerts don’t need title. Usually the decision can be
        summed up succinctly in a sentence or two
  - - - Linear
      - Circular
    - - Determinate
        
        Can be measured and the indicator usually
        runs from 0 to 100
      - Indeterminate
        
        Cannot be measured, the indicator usually
        animates continuously until the processing is done
  - - - do not contain actions
      - cannot be swiped off screen
      - Toast is similar to Snackbar, except they are primarily
        used for system messaging
- - - - main uses for swiping
        
        Dismissing an Item
        
        Changing view
      - Swiping left and right is possible, depending on the
        direction of the moving finger
      - act of touching the screen with index finger and quickly moving it left or right and immediately lifting the finger
    - - Pinch-out
        
        Moving index finger and thumb farther
        away, usually results in unzooming
      - Pinch-in
        
        Moving the index finger and thumb
        closer, usually results in zooming
      - done by using a thumb and a
        finger and form it into a pinching gesture
      - general process of ‘zooming in’ or
        ‘zooming out’ a View
    - - types of scrolling
        
        Flinging
        
        scrolling that occurs when a user drags and lifts her finger quickly. After the user lifts her finger, the viewport will keep scrolling until it stops by de-accelerating.
        
        Dragging
        
        scrolling that occurs when a user drags her finger
        across the touch screen
      - scrolling is in both the x and y axes it is called
        panning
      - general process of moving the
        viewport
    - - Interpreting the data to determine gestures criteria
      - Gathering touch events data
