7.1.0 - 2021-04-23

Added

Added new build options to disable Skia and use our original graphical primitives, resulting in a very smaller libtcvm (~3MB) that also works on OpenBSD. Thanks @erathke for this contribution! #287

Usage: cmake <source_dir> -DUSE_SKIA=OFF

Changed

Updated library Axtls from version 1.5.4 to 2.1.5 to include support for TLS 1.2.

Fixed

Android
- Reverted Android build to target SDK 29 in order to fix support for Android 11.
Launcher
- Fixed Android deploy on case sensitive systems.
Simulator
- SSL: Fixed bug on some JDK implementations that would throw IOException on getInputStream after EOF.

7.0.4 - 2021-04-06

Changed

Simulator: Removes resizing of font on simulator for better fidelity across platforms - #293

Fixed

Android:
- Fixed packaging of binaries included in the release.

7.0.3 - 2021-03-09

Performance boost and reduced binary size on Linux and Android - This was actually our mistake, those targets were being built for debugging since we started using CMake. This release should have performance at least twice as better as the previous releases built with CMake.
Build system improvements
- SQLite3 source code removed from our repository, downloading and patching is performed by CMake.
- Android build improved, it should be A LOT faster for most systems.
Edit and virtual keyboard performance improvements

Known issues

Android prebuilt binaries included in this release are broken, skip this release for Android or rebuild the binaries from the sources and replace them locally.

Changed

Removed Cielo Lio text printing support, reducing the Android binary size. (Let us know if you need this feature back)

Fixed

Android:
- Fixed launching third party apps using Vm.exec
- Fixed permission for writing on storage for android-29

Starting from target-sdk 29 application should use scoped storage https://developer.android.com/training/data-storage#scoped-storage

API:
- MessageBox: fixed NPE during unpop when the MessageBox is created without buttons (i.e. button captions is null) - #304

7.0.2 - 2021-02-09

Added

String: added missing constructors that handle charset encoding.

Fixed

XmlReader and SOAP: Fixed bugs introduced on version 7.0.0.
Image: Fixed bug introduced on version 7.0.0 that caused animated images to draw only its first frame - #296

7.0.1 - 2021-01-28

Added

Added a few tweaks to improve drawing performance:
- Improved color type conversion performance by using compiler specific byte swap functions.
- 🚀 Greatly improved image drawing performance by performing color type conversion only once, instead of letting Skia handle it automatically on every draw operation.
- 🚀 Greatly improved drawing performance for fully opaque images, by skipping alpha channel conversion on draw. Drawing JPEGs and opaque PNGs got over 10 times faster on some tested devices.
- Improved text drawing performance by caching font objects and avoiding unnecessary font loading.

Changed

Force usage of software graphics on Linux/ARM systems until we find a proper way to detect support for hardware accelerated graphics - #259

Fixed

Class java.util.Objects would sometimes be not available on the device.
Segfault during SDL initialization reported in some systems - #263, #265
Fixed screen not updating on some devices, by refreshing the SDL_Surface on repaint.
XmlTokenizer was still trying to use the old byte implementation when running on device.

6.1.1 - October 2020

Hello! This minor release has as main objective:

Static SDL2 - Brings it back to work properly on Angstrom for target Linux ARM;
Display env-vars - Configurable displays bounds;
SSLSocketFactory - Change SSLSocketFactory to always yield a SSLSocket;
Fixes - Minor bug fixes 🔧.

Join our community on the telegram to give feedback about this release!

Static SDL2

SDL is now statically linked for Linux arm32v7. Some very simple systems do not have the possibility of installing SDL2 in an easy way. On Angström-type systems this required a certain kludge exporting the path to extern .so with LD_LIBRARY_PATH=<path-to-.so>. We didn't want it to be hard, that's why the change!

Display env-vars

We now introduce 3 environment variables for execution. Since we do not have an automatic viewport they need to be set up they are:

	TC_WIDTH	TC_HEIGHT	TC_FULLSCREEN
Description	Size of `width` in pixels	Size of `height` in pixels	Only do something when comes to `false` or `0`
Values	int	int	bool

You can use them as follows for Linux and Linux ARM platforms:

$ TC_WIDTH=1280 TC_HEIGHT=720 TC_FULLSCREEN=false ./Launcher MyApp

When the fullscreen is deactivated the TC is opened in a window and its logic like:

width -= width*0.09;
height -= height*0.09;

That should change soon. See more in #99.

The syntax #<number> is related to pull request in GitHub repository.

`SSLSocketFactory`

Should always yields a SSLSocket when in SSLSocketFactory. As SSLSocketFactory extends SocketFactory and does not override the createSocket(String, int) method, and calls from super classe. As SocketFactory yields plain sockets...

This fix just delegates to createSocket(String, int, int) passing the default Socket.DEFAULT_OPEN_TIMEOUT as the open timeout argument. Maybe it should be better to call new SSLSocket(String, int), but this constructor does not exists yet. See more in #122.

Thanks @jeffque 😃!

Fixes

Corrections were made:

Launch args not being parsed, i.e., ex. /density #94;
SDL didn't work properly in systems without libSDL2-dev, CreateRenderer() bug #99;
SDL use SDL_Surface instead of SDL_Renderer when hardware accelerated graphics is not available;
iOS: Update youtube-ios-player-helper from 0.0.16 to 1.0.2. This is required because UIWebView, a component used by this dependency, is deprecated resulting the error ITMS-90809 when uploading the app for the app store;
iOS: fix missing icon files when generating;
Remove some Sun private libraries are not guaranteed to be available to any JDK besides the Oracle JDK 8 or previous;
Fix AnonymousUserData usage;
StringBuffer adds missing CharSequence constructor.

6.1.0 - July 2020

Welcome to the July 2020 release (version 6.1.0). We hope you enjoy the updates in this version. The key highlights are:

Maven plugin new version - your pom.xml file should change;
KnowCode Compatibility - It is now possible to run Android XMLs Layouts on Linux Arm;
Virtual Keyboard - New look and animations;
Using external applications - Through the runtime.exec method;
Anonymous user statistics - There is now an option to contribute by sending anonymous data;
Changing the SDL implementation - Removing the SDL code from within the TotalCross SDK and changing the static to dynamic link.

Join our community on the telegram to suggest activities and learn about development for embedded systems.

Maven plugin new version

After the latest Language Support for Java extension updates, some systems had compatibility issues with Java 11. We launched a new version of the TotalCross maven plugin to solve them, the 1.1.6. You must change the following line:

...

<plugin>
  <groupId>com.totalcross</groupId>
  <artifactId>totalcross-maven-plugin</artifactId>
  <!-- This line: -->
  <version>1.1.6</version>
  <configuration>
    <name>${project.name}</name>
    <platforms>
    
...

KnowCode compatibility

In this version, a name tag was added to ContentHandler (Pull request #20), making it possible for KnowCode, a tool that uses a neural network, to convert interface images to XML and TotalCross, allowing it to run on Linux Arm with the same performance as an application built directly with the TotalCross SDK.

Find out how to use KnowCode by clicking here.

Virtual Keyboard

In this milestone some improvements were implemented in the keyboard, which are:

In Linux Arm the virtual keyboard is enabled by default. To disable it just put Settings.virtualKeyboard = false in your MainWindow class;
In order to improve performance and make the design cleaner, the ripple effect animation on the keyboard buttons was removed;
In order to obtain more effective responsiveness, the calculations of width and height were changed, leaving it less dependent on absolute values;
To make the interface richer, sliding animation was added to the popup and unpopup of the virtual keyboard. You can see these changes in detail in pull requests #40 and #65.

In the images below you can see the visual difference:

After:

External applications

To allow the use of external libraries in the simplest way possible is one of TotalCross goals. There is a branch in our repository called feature/tcni-rebased which (still a Proof Of Concept) allows the use of these external libraries

TCNI is a foreign function interface programming framework that enables TotalCross/Java code running in a Java virtual machine to call and be called by native applications and libraries written in other languages such as C, C ++ and assembly.

But while TCNI is not ready to be launched, we have developed a middle ground that allows the use of external applications in TotalCross, through the method runtime.exec(). This method creates a new process and executes the command you passed in this new process (Pull request #21).

For example, create a python script to access a temperature sensor and with the runtime.exec() get the return of it, as you can see in this example:

To better understand how it works using a sample application click here.

Anonymous user statistics:

When TotalCross decided to become a free and open source tool, the decision was made to no longer require an activation key from the user, which was previously necessary to differentiate free users from customers. As this removal would imply resolving a series of errors and making many changes, the team decided to generate an eternal and unlimited key and use it as a default, provisionally, until we resolve some pending issues and can go back to this point and withdraw it for good.

So in 6.1.0 we went back to that and removed the activation key, including the class register.java, as you can see in detail in pull request #53.

And to better track which users preferences when using the TotalCross SDK, we set up the SDK to ask if the developer wants to contribute anonymous data and if the answer is positive, we record parameters for Deploy, timezone, launchers, operating system version and version of TotalCross used.

You can see the details of the implementation in Pull Request #66.

Change in SDL implementation

We chose to remove SDL code from the SDK TotalCross in this version to improve the build organization and allow people to customize the build of their facilities according to their hardware.

In addition, we changed the SDL link from static to dynamic because:

Allows the distribution to have corrections and be used without having to compile the TC again but the guy needs to install the SDL before TotalCross
Avoids License compliance problems as FOSSA warns about the SDL license (GPLv3).

For details, see pull requests #23, #24, and #68.

Other changes:

Reverted scroll flick animation back to a previous version to fix a bug that caused the content to be pulled back after a scroll;
Fixed creation of TotalCross modules (.tcz files) using Java headless;
Fixed round border on Container;
Fixed Switch Bar not being drawn;
Fixed wrong size returned by FontMetrics.stringWidth(String s) on devices that use skia with .ttf file type fonts.
Fixed Torizon/Wayland SDL initialization;
Fixed FadeAnimation: the animation is now working as intended.

5.0.0 - 2019-04-15

Highlights

TotalCross is now aware of the device's screen pixel density and uses this information to scale UI elements uniformly on different platforms.
The font size is now expressed in scaleable pixels (sp) and will now scale uniformly on different screens. The font size should now be expressed as a constant value or based on Settings.deviceFontHeight, but never based on the screen's resolution or target platform.

ℹ️ Existing applications may require adjustments to their font sizes!

Improved overrall UI responsiveness and reduced application start time on Android
Several Vm.sleep calls in the vm had their time reduced by 50% or more, some calls were replaced with Thread.yield()
On Android and Java, reduced overhead in the event thread to improve UI responsiveness

Screen density support

All graphical components can now be scaled to have approximately the same physical height on any screen resolution.

Density by OS

Android and iOS: these devices expose a manufacturer-provided screen density value. On TotalCross 5 applications, this value is retrieved by default and used to ensure consistent component sizes across devices
Java: based on scale, e.g. /scale 0.5 = density 2.0, you can try different densities on the emulator by changing the scale command line argument
Win32 and WinCE: Most Windows devices do not natively expose screen density information and, thus, are kept at density 1.0. To improve the look and feel on smaller screens, we use a density of 0.75 on screens with width or height less than 320
Other platforms: nothing changed (= density 1.0)

Font

The font size is now expressed in scalable pixels (sp), this abstracts away the actual physical dimension (screen pixels) of the font. This way, their actual physical size is calculated based on the screen density. e.g: A font with size of 20sp with different screen resolutions:

Density 1.0: actual size 20 pixels
Density 1.5: actual size 30 pixels
Density 2.0: actual size 40 pixels
Density 0.75: actual size 15 pixels This change shall render TotalCross apps ready for different screen sizes with minimal implementation effort.

Updating for 5.0

Using Font.getDefaultFontSize is no longer necessary, you may now use constant values and the font size will be adjusted accordingly. Applications that tried to “guess” the appropriate font size based on screen resolution may need adjustments. Applications that used Settings.uiAdjustmentsBasedOnFontHeight should have their graphical components resized more uniformly across different platforms and screen densities.

Density Independent Pixels

Controls may now have their dimensions expressed in density independent pixels units (dp), which are scaled for the screen based on its pixel density. e.g:

// adds Button with height of 20dp
add(new Button("Ok"), RIGHT, BOTTOM, PREFERRED, DP + 20);

This is now the preferred way of setting the control’s dimensions.

Improved support for animations

We now provide a central update event that controls can register for. This event fires periodically and is meant to be used to drive all animations in the framework. In comparison to using timer events for animations, this approach uses less CPU and memory, and behaves better under high CPU usage scenarios.

Updating for 5.0

Several classes were updated to use the new update events and the effect on them should be noticeable without any changes. In special, we would like to highlight the ScrollContainer and the ControlAnimation components. Users are encouraged to replace similar uses of threads, sleeps and timer events with update events.

Smoother scrolling

The ScrollContainer and the Flick components were updated to provide smoother and more precise scrolling. The changes include the usage of quadratic easing animation and exponential decay. The Flick also factors in the screen’s pixel density and offers the user the option of tuning the flick acceleration. Lastly, Flick also supports consecutive drags to increase the scrolling speed.

Updating for 5.0

Most of the changes made are transparent to the user, but there were some breaking changes on Flick. User may have to remove the usage of fields that are no longer available.

Icon control

With the new Icon control it’s easier to add beautiful and meaningful icons to your application.

This is now the preferred way of adding icons to your application and should be favored over image files. One major reason to favor icon font sets over images is that they are highly scalable and will look sharp in any resolution while using only a fraction of the system resources an image would use. Material Icons are already bundled with the sdk and the IconType interface may be used to implement more font sets.

Alpha support for Labels and Icons

It’s now possible to change the opacity of text and icons within Label or Icon controls. This is a key feature to design beautiful applications, as it allows text to remain legible over any background color. Transparent status bar

Currently only supported on Android, but iOS support will be ready soon.

Navigation Drawer

All the previously listed changes were put in use to futher develop the SideMenuContainer, complying with the Navigation Drawer pattern defined by the Material Design guidelines (https://material.io/guidelines/patterns/navigation-drawer.html):

Action bar height is now 20 dp
Bar title and menu items using the Roboto Medium font (when available)
Labels and icons now use the correct font size, weight and opacity
Keylines and margins are respected both inside and outside the side menu (with a special exception for really small screens)
Smooth slide-in and out effects, with fade effect during slide removed
Resting elevation over the content
Swipe to open support is still in its early stages, but should be functional for most applications
Adjusts automatically when used with transparent status bar

Added

SideMenuContainer.Sub, a collapsible submenu for the navigation drawer
MaterialWindow, a popup window that slides from the bottom to the top of the screen

Changed

Camera: On Android, choosing an image from the Gallery no longer creates a copy of it when not necessary (images from a cloud service still require a local copy) - TotalCross#400
Java
- ByteArrayOutputStream: added several missing methods - TotalCross#478
- System: added method arraycopy
- Charset: method forName now correctly validates the given charset name and may throw IllegalCharsetNameException

Highlights

Android
- Android package is now built with SDK 27 (previous releases were built with SDK 22) and the latest NDK r17b (up from NDK r8b!) - The minimum SDK level required to run TotalCross applications remains unchanged (SDK 10)
- Applied the Android recommended changes to better handle activities and contexts to prevent possible resource
- TotalCross now asks for the user permission to access phone state and location on startup

🚧 On Android, features that require user permission during runtime may not be working. Please report if you have any trouble with permissions.

Launcher
- The Launcher (simulator) can no longer be used without an activation key
Deploy
- Check paths from pkg file and throw more meaningful error message when a path is invalid
- Print Deploy exceptions on System.err instead of System.out and using the default stack trace output
Whiteboard
- No longer recreates the content image when repositioned - #187, #196
ListBox
- Deprecated method add(Object[] moreItems, int startAt, int size) as it was redundant and more confusing than helpful
ComboBox
- Deprecated method add(Object[] moreItems, int startAt, int size) as it was redundant and more confusing than helpful
Radio
- Added feature autosplit - #180

Added

EscPosPrintStream - New API which supports several ESC/POS printer commands - refer to the class documentation and samples for more information
Notification and NotificatonManager - Allows the creation and presentation of local notifications to the user, currently implemented for Android, iOS and Java.
ImageLoader - New class to help managing image resources, especially jpeg images. Currently no caching is done by the class.
Image
- Added static methods Image.getJpegScaled and Image.getJpegBestFit to load jpeg files using fast IDCT scale, more about this here
Java
- Added classes ByteArrayOutputStream and UncheckedIOException
- Added classes Charset and UnsupportedCharsetException, added also String.getBytes(Charset)
Added Cp437CharacterConverter, which supports encoding and decoding characters using the CP-437 charset (also known as IBM437, windows-437, among others). Especifically added to be used with EscPosPrintStream to properly support writing text to Leopardo A7.
Convert
- Added method charsetForName(String name), which returns one of the registered charsets available
- Added method registerCharacterConverter(AbstractCharacterConverter characterConverter), which allows users to create and registers their own subclass of AbstractCharacterConverter to support custom encodings
- Added several aliases to the existing ISO-8859-1 and UTF-8 CharacterConverter classes and changed setDefaultConverter to be case insensitive and support any of listed aliases.

The existing CharacterConverter class and subclasses were changed to extend AbstractCharacterConverter, which extends Charset. The actual support to Java Charset is almost none, the main goal is to allow the usage String.getBytes(Charset) with the existing CharacterConverter and let users encode strings with different charsets without changing the charset used by the rest of the application through Convert.setDefaultConverter.

Deprecated

ListBox
- Deprecated method add(Object[] moreItems, int startAt, int size) as it was redundant and more confusing than helpful
ComboBox
- Deprecated method add(Object[] moreItems, int startAt, int size) as it was redundant and more confusing than helpful

Known issues

iOS
- Applications signed for enterprise distribution cannot run on iOS 12 - apparently it fails to validate the certification chain that validates the signed application. It's not clear yet if this was an intended change or a bug, but there's no word from Apple about it yet.
- Applications signed for distribution through the AppStore cannot be uploaded because of changes on the way image resources are handled starting from iOS 11. We are working on a definite fix for this, in the mean time feel free to contact us to manually package the application for the AppStore.
Notification
- Android lacks support for custom images for notifications, only the default TotalCross logo is supported
- Notification crashing application on Android - #255
PushButtonGroup
- The fix for the drag event caused PushButtonGroup to be unclickable on Win32, affecting all dialogs - #263
