Details

• Fixed bug in Javascript bridge that seemed to affect Android only. This bug would sometimes cause get() to
  return null for a Javascript expression that should be non-null.
• Fix for #1645 when a style was changed on the EDT the currently queued async paint got changed as well
• Updated the usage of the @inheritDoc javadoc tag which was misused thru the entire codebase
• Fix for NPE when initializing the UI too soon Fix for NPE when initializing the UI too soon
• Added JavaDocs and code samples to Dialog Added JavaDocs and code samples to Dialog
• Minimised the overhead of drawString in Android in a similar way to the iOS port by drawing on a bitmap within the EDT instead of on the Android thread.
• Fixed infinite progress javadocs
• Fixed bug with OnOff switch that printed the ‘on-off’ state of the switch as text even if the flag was set to disable
  this.
• Added ability to programmatically set the on, off, and mask images for the OnOff switch to allow for greater
  ‘per-instance’ customization of an off switch.
• Fixed transform issue on iOS mutable images reported at http://stackoverflow.com/q/34770700/2935174
• Added easy ability to toggle on/off the new paint modes for Android
• Initial work on new graphics optimization that caches paint data
• Merge pull request #1643 from @McSym28 Socket.java. isSupported() should be static
• Merge pull request #1637 from @ddyer0 – remember the requested size for derived fonts
• Fixed issue with text fields intermittently showing the text from the previous text field when clicking ‘Next’ in async
  edit mode on iOS.
• Merge pull request #1636 from @ddyer0 – Fix an additional error loop in the VM socket implementation
• Minor performance improvement for async paint
• Workaround for usage of gradients in designer where developers set the same color on a linear gradient to get a solid color
• Fix for URLImage to throw exceptions sooner: http://stackoverflow.com/questions/34713004/an-exception-occurred-during-transition-paint
• Added support for Picker preferredPopupWidth and preferredPopupHeight that can be used on platforms like iPad
  to decide how big the picker popup should be. Currently only implemented for iPad, and not relevant to iPhone.
• Merge pull request #1633 from @ddyer0 – fix a fencepost error in flowlayout
• Merge pull request #1633 from @ddyer0 – when readFromStream or writeToStream throw an IOError, mark the stream as no longer connected.
• Merge pull request #1633 from @ddyer0 – Added event type information to ActionEvent
• Removed vestigal keyboard support sections as they can’t effectively be used anyways. Keyboard changes
  ended up being too far reaching for this simple flag to be sufficient for reverting to old handling.
  The new handling appears to be working for all use-cases anyways.
• Added 2D transform support for mutable images on iOS. This effectively fixes issues with being able to share
  charts that are generated as images #1629
• Added new UITimer constructor for further simplicity
• Replaced array.length calls inside for loops with local ‘length’ variables
• Fixed issue with transforms on mutable images in JavaSE port that would cause Graphics.getTransform() to
  always return the identity transform
• Added support for drawing shapes on mutable images in iOS #1629
• Fixed async editing support on Android when TextureView is used.
• Added addComponentToSideMenu() to Toolbar this will allow devs to customize the sidePanel even for permanent side
  menu
• Added ability to center the title in the Toolbar Added ability to center the title in the Toolbar
• Fixed cancelLocalNotification to only delete the notification whose deletion was requested
• Fixed regression in left aligned labels http://stackoverflow.com/questions/34565387/button-settextpositionlabel-left-render-wrong/34581225
• Fixed remove command from title
• Added ScaleImageLabel to simplify the process of adding a label that will scale correctly
• Added AssignableExpression to ParparVM implementation. This will allow the translator to work with
  instructions in a more generic way when determining if an instruction can be reduced to a single expression
  that can be assigned to a variable or passed as a parameter
• Changed ParparVM primitive local variables to use C locals instead of storing them in the stack.
  This should bring performance improvements on two fronts: 1. STORE operations now map to a single assignment
  instead of two, since we don’t have to assign the variable type. 2. LLVM should be able to perform better
  optimization surrounding C locals.
• Fix for launching the android sms activity
• Pull request from @ddyer0 Fix for two problems with Sockets; data corruption and infinite error loop when input socket is closed.
• Fix for #1623 tickering should cycle
• Refactored ParparVM’s custom Invoke and Jump optimizations into separate Instruction classes so that there
  is no confusion on how the Jump and Invoke instructions interact with the stack.
• Added getStackOutputTypes() and getStackInputTypes() methods to Instruction in ParparVM so that optimizers
  can inspect instructions to see how they affect the stack. This will eventually allow for better reduction of instructions during the optimization phases.
• Improved CustomInvoke optimizations in ParparVM to cover many more cases that were missed
  before. This should further reduce redundant stack operations surrounding qualifying method invocations.
• Added small optimization for binary integer arithmetic ops in ParparVM to directly assign result to local variable
  instead of first pushing it to the stack, then popping it to a local
• Improved the performance monitor to show UIID’s
• Fix for some edge cases of component animation: https://groups.google.com/d/msgid/codenameone-discussions/fdd7ce70-d8ac-418b-96e0-0cd9ca529cb1%40googlegroups.com
• Fixed issue with android async keyboard still showing on form change
• Added the missing overflow icon
• Fixed the decay motion to stop if last 4 returned animation values are the same
• Fixed potential exception in animation layout transition that might collide with a remove operation
• Deprecated the com.codename1.codescan package. Going forward developers are encouraged to use the
  cn1-codescan cn1lib instead. https://github.com/codenameone/cn1-codescan/
• New ability to force popup dialog in a specific direction
• Flipped the default for “ends with 3 points” to be false as this slows down performance slightly
• Fixed special case that caused scroll to 0,0 when first field of form requests focus whether or not it is already visible.
  This improves usability of the MaterialLogin demo.
• Fixed problem with rendering FontImage, IndexedImage & RGBImage
• Caching derived font instances which can significantly boost performance by allowing the native side of the
  fence to cache additional data on the font object
• Fixed issue with async editing changes causing text field to close and reopen sometimes when switching to a
  different field
• Fixed masked icons to render correctly in the new pipeline
• Fixed the android get contacts to ignore case upon returning contacts
• Added a picture to some of the Simulator contacts
• Implemented component drawing for labels and buttons in the native async layer
• Native implementation of label and background drawing to squeeze every ounce of performance
• Major refactoring of the UI with the goal of improving on device performance for iOS/Android by moving
  frequently used code into the IMPL layer and allowing us to optimize it
• Added support for Android async editing
• Improved efficiency of Container.contains() for containers with many children
• Adjusted the decay scroll parameters based on comparisons with native iOS app scrolling
• Added additional checks for peer components before firing the onParentPositionChange event.
  This dramatically improves smoothness of drag scrolling
• Performance optimization for scrolling a large set of elements when we have no peers
• Changed default scroll motion to use exponential decay instead of friction to simulate more closely native behavior.
  You can revert to the previous friction style of scrolling by setting the theme constant ‘ScrollMotion’ to ‘FRICTION’.
  You can tune the decay parameter ‘DecayMotionScaleFactorInt’ to adjust how sensitive the scrolling is.
• Removed excessive pointer events from event dispatch to prevent slowness during dragging
• Optimization for stringWidth that should avoid calls to that relatively slow API by caching the value within labels
• Added a binary search for the ‘viewable’ children of a container that can be used to make it easier to only paint
  visible children for large containers
• Removed redundant opengl calls to try to make painting more efficient
• Fixed contact getDisplayName() to never return null
• Removed a rectangle allocation that caused a GC in the EDT paint cycle. This fixes some jitter that occurs
  while scrolling
• Fixed the animation manager scrolling behavior so it won’t misbehave when pulling from the top
• Made style animation work as expected for multiple elaborate cases
• Improved add/remove component to act as if the component was already added/removed and avoid some exceptions
  in cases that would be serialized
• Added ability to detect an empty border
• Fixed regression with ComponentGroup due to changing method signature
• Better error handling in the JavaSEPort
• New title animations and style animations API’s
• Additional improvements for side menu bar preventing potential issue
  with animations
• Fix for potential exception if an animation is running while changing the Toolbar
• Fixed the animations and add/remove operations so they won’t collide. If an animation is in progress add/remove
  will get queued until after the animation is performed
• New animation framework that accepts all animation requests globally and processes them
• New methods for Integer & Character classes
• Added getTitleComponent to the Toolbar
• Fixed regression in ios keyboard that caused it to not respect the ios.keyboardOpen build hint.

• Fixed issue with background location monitoring on iOS 9
• Fixed textarea resizing to work properly on iOS 7 and below
• Fixed edge case of text area being edited in legacy mode when part of the text area is covered by the keyboard.
  Now the native editing component is sized to only occupy the space above the keyboard so that scrolling
  happens more smoothly as typing, and the textview will auto scroll as the cursor moves in and out of view
• Fix so that legacy keyboard doesn’t push the selected text area up any higher than the top of the text area
• Fixed issue with keyboard upside down multiplier on iOS 7
• Changes to keyboard on iOS to deal with quirks on iOS 5. Also modified some of the orientation detection
  handling that didn’t seem to be working correctly on iOS 5.x

• Simplified code that allows binding standard boilerplate crash reporting logic
• Shorthand terse syntax for layered layout
• Fixed regression with testflight builds
• Added support for native OS fonts that are builtin to iOS/Android with multiple weights.
  This is mapped to the simulator on Windows/Linux as Roboto due to copyright issues with Helvetica.
• Fixed for exception in table layout
• Fixed issue that caused a revalidate to occur off the EDT in iOS when the keyboard is about to be shown.
  This may fix numerous issues. But, at least seems to fix an NPE from #1601
• Fixed issue where the first contact is always blank on iOS. Changed contacts to come out sorted by default #1598
• Changed Contact.getDisplayName() to return an alternate value like the phone, email, name if the contact has no display name #1598
• Fixed iOS port not respecting setChunkedStreamingMode. iOS8 had been using chunked streaming by default
  for multipart requests. Now it will only use chunked streaming when setChunkedStreamingMode() is called
  with a non-negative integer argument
• Fixed regression in Javascript bridge that broke execution on Android
• Fix for #1602 – Menu missing with Android 6 Marshmallow
• Added ability to hide/show components without removing them (setHidden)
