The Gear’s simple home structure 

Understanding the Gear’s home structure is the key to designing engaging apps. The Gear’s simple home structure provides easy access to useful features. From the watch face that forms the center of this structure, users can access notifications, widgets, and the quick panel by swiping or rotating the bezel, and bring up the app list by pressing the Home key.

The watch face presents useful information as well as the current time. It is displayed whenever users turn on the Gear’s screen or press the Home key. Since users see the watch face most often, it should both provide useful information and satisfy the user's design tastes. While only one watch face can be used at a time, users can switch their watch face regularly.

The quick panel displays the current status and basic settings icons of Gear. Users access the quick panel from any screen by swiping down from the top of the screen, and adjust the settings by tapping the icons. The settings included in the quick panel are fixed by default.



App icons should be designed in a container to ensure consistency with other apps in the app list. We recommend using round container measuring 170x170 pixels. Icons in other sizes will be automatically resized when applied to the screen.
If an icon is not created with a round container, it will be reshaped. Depending on the dimensions of the icon, it will be cropped or reduced in size and placed in a gray container


System font

The Gear uses Breeze Sans as the system font. Breeze Sans comes in light, regular, medium, bold, and condensed. The condensed option also comes in thin, light, regular, medium, and bold types. You can download Breeze Sans typeface:


Users can input text with an input delegator or a keyboard. Input delegators are used for suggestions, voice input, emojis, and handwriting. A keyboard is used when suggestions aren’t available or privacy is needed, like when you need to enter a password.
When the keyboard appears, the entry field is moved upward, so make sure that the location of the cursor remains visible on the screen. We also recommend letting longer phrases overflow to the left side of the screen so that users can revisit them by swiping over the entry field without leaving the keyboard.

Input delegators

App-provided suggestions

Users can select one of the suggestions provided by the app.


Users can input words with their voice.


Users can select Unicode emoji.


Users can use a finger to input from the on-screen keyboard if the option is turned on in Settings.





gear watch designer BUILD PASSWORD troubleshooting

I went to Build it again and this is the message I get. Signing Fail Keystone Password was Incorrect. What does that mean? How can I fix it?
It's likely that the password to entered for the Author certificate is wrong. Try to regenerate the Author.p12 file with the correct password.

how to install (and debug and use and dvp u first "hello') TizenStudio to develop samsung for products on mac OSX sierra and later : example of Gear S, Gear S2, Gear Fit2, Gear S3, Gear Fit2 Pro and Gear Sport



Make your own Gear watch face in just a few steps on your Mac and PC.
Now available for Gear S, Gear S2, Gear Fit2, Gear S3, Gear Fit2 Pro and Gear Sport

For the example of Gear Fit2 Pro :

The link for dvl:

1/ télécharger le SDK (win, ubuntu ou mac)

sur mac: web-ide_Tizen_Studio_2.2_usa_macos-64.dmg

2/ on lance ce .dmg;

3/ error:

il faut java KDK ≥7

Et un bug! Aurait du prévenir que JDK≤8

il faut enlever 9.x si vous l'avez installé...
sudo rm -fr /Library/Java/JavaVirtualMachines/jdk-9.jdk/
sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane
Don't forget to check the
manually and see what your real JDK version is.

4/installer java JDK 8.

Et après >1h pour ce manager,

on obtient:


Tizen studio 2.0 is not working on macOS Sierra.
The application is frozen on the workspace selection page and no button is clickable.
Tizen Studio freezes in "workspace launcher".

Open Terminal
Go to
There may be the file named eclipse (binary file) (I'm not sure above path is correct , but you can find the file named eclipse which is binary around that location )
Execute Tizen Studio typing in as below
./eclipse -debug -consoleLog
Some log will be shown on the terminal

only one solution: downgrade to java 1.8.0_151 or 131...

archive java JDK 8

after debugging, the use of TizenStudio 2.2 and Tizen 4.0 platform (API 4.0)

emulator for gear fit2

Till now (2018-01) there is no Emulator on Tizen Studio for Gear Fit series. 
But you may run your projects on Square Emulator in order to test Fit series projects. You can fix the resolution of your project from config.xml.
As the resolution of Gear Fit 2 is 216 x 432, i am setting height and width accordingly.
<?xml version="1.0" encoding="UTF-8"?>
<widget xmlns:tizen="" height="432" width="216" xmlns="" id="http://yourdomain/XXXX" version="1.0.0"  viewmodes="maximized">
    <tizen:setting screen-orientation="portrait" context-menu="disable" background-support="disable" encryption="disable" install-location="auto" hwkey-event="enable"/>
And taking the emulator having resolution 320 x 320 as there are no other square emulator option on the Tizen Studio. Hopefully this technique will solve your problem.

running on your watch
error SIGNATURE_VERIFICATION_FAILED[23] when running it.
pb certificate
From package manager "Extension SDK" , Check whether you have installed Samsung Certificate and Wearable extension or not . You have to install these two extensions.

you must create 
a Samsung publication certificate
AND a Tizen certificate

and It works!!!!

Just select not only the emulator but your device (device manager)...

In french, we say : OUF!


qq remarques en anglais sur le monde java et mac

MacOS no longer ships with Java preinstalled (6.0), so you’ll need to download and install java on your own if you need it in MacOS 10.13 or 10.12. This is to insure that the most recent version of Java is installed on the Mac if it’s needed, aiming to lessen potential security issues that may come up with older versions of the Java software (though older versions of Java can be installed if need be for a specific reason).

Moreover think that  some parts of CS6 as Illustrator CS6 need legacy Java SE 6 runtime.
Then you must use terminal mode...
Adobe Illustrator CS6 with Java 8?

On my Mac, the creation of these directories
sudo mkdir /System/Library/Java/JavaVirtualMachines/1.6.0.jdk
sudo ln -s '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents' /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents
sudo mkdir /System/Library/Java/Support/Deploy.bundle
alone allows me to run Illustrator CS 6 even when neither Java 6 nor Java 8 is installed. Apparently, Illustrator only checks for the presence of these directories to determine whether Java is installed (it actually launches even when java itself is absent, provided directories above are created). I would like to know, which functionality in Illustrator CS 6 actually requires Java, as it apparently can launch without it.
Note: On OS X 10.11 and later you'll need to disable System Integrity Protection from the Recovery HD using csrutil disable in Terminal. Have a look at: About System Integrity Protection on your Mac & How to Disable System Integrity Protection (rootless) in OS X El Capitan.

The latest version of JDK

Java SE 9.0.4; 16 January 2018

tizen needs Java SE Development Kit 8u162

world of Java

Java SE Development Kit). For Java Developers. Includes a complete JRE plus tools for developing, debugging, and monitoring Java applications.

JRE:  Java Runtime Environment,
The JDK also comes with a complete Java Runtime Environment, usually called a private runtime, due to the fact that it is separated from the "regular" JRE and has extra contents. It consists of a Java Virtual Machine and all of the class libraries present in the production environment, as well as additional libraries only useful to developers, such as the internationalization libraries and the IDL libraries.

On 17 November 2006, Sun announced that they would release it under the GNU General Public License (GPL), thus making it free software (released by Oracle Corporation in the form of a binary product aimed at Java developers on Solaris, Linux, macOS or Windows. ).
