    Sometimes, the Galaxy Watch Designer can’t find your Java Runtime Environment because of your operating system or because it was installed in an unusal folder.

    To solve this problem:
    1. Open GalaxyWatchDesigner.ini in the Galaxy Watch Designer installation folder. By default it is "C:\Program Files\Galaxy Watch Designer"
    2. Add the path to the javaw.exe file at the bottom of the in file, then save the file.

    Add javaw. exe location.

    Please try as below.

    1. Add below line to “~/.bash_profile

    export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

    2. Add below to PATH variable. Or you can simply install JDK (not JRE) that will do above things automatically.

    $JAVA_HOME/bin

    Having too many complex conditions may causes problems. Only use conditions to show or hide components. For more complicated motion designs, use animations.

  • .A

    You can change this in Rotation properties > Rotate.
    For example, a complication showing the battery level will have a watch hand that rotates clockwise through 360°. Using the settings above will change the rotation to anti-clockwise through 180°.

    12 o’clock starting point, rotate 180 degrees clockwise

    3 o’clock starting point, rotate 180 degrees clockwise

    You can also customize the start and end points of a watch hand’s rotation from Preview.

    A. Creating shadows

    You can create object shadows by using Adjust Color to set the color of the original object to black, then positioning it as required.

    1. Copy and paste the original object.
    2. Use Adjust Color to set the color of the new object to black.
    3. Set the position and layer position of the new object to make it look like a shadow. (from the same position as the original object, move the new object downwards by around 7 pixels.)

    B. Creating button areas

    Create transparent button areas by selecting an image, setting its opacity to 0%, then setting it as a button.

    C. Repeating conditional lines

    You can create repeating conditional lines by copy and pasting existing conditional line patterns. For example, you can set an image to show or hide every 30 minutes.

    1. Add the image.
    2. Set the Timeline scale to Minute.
    3. Set the properties to have the image show for the first 30 minutes and hide for the next 30 minutes.

    4. Set the Timeline scale to Hour.
    5. Select the 30 minute show/hide period and copy it.
    6. Paste the period.

    *Note that excessively detailed patterns can cause the device to function incorrectly.

    D. Adjusting the length of animations

    Let’s try tripling an animation’s duration.

     

    1. Load the animation object.
    2. Double click on the animation to enter edit mode.
    3. Animation layers are set to show 1 frame per 1/15 seconds by default. In the Set frame delay popup, set Apply all frames to delay with 3 frames (refers to image)

    4. Return to Normal mode by double clicking on any outside area.
    5. When you test out the animation, it will be 3 times longer than before.

    *Note that the animation is not actually synchronized with the time on the watch face.

    Images that contain bright colors and animations use battery power more quickly.

    Watch faces with always-on pixel usage of more than 15% can not be built in GWD due to battery drain and burn-in of the watch.
    However, if it exceeds 15% temporarily, the watch face could be built. In this case, the store registration can be rejected during the quality verification process or it can be canceled by the user complaints even if the watch face was built.

    The author certificate is used for signing and verifying your app. It identifies the developer of the app and ensures the following: the app is not distributed by someone else, the developer can publish updates, and secure IPC (inter-process communication). After you publish an app, you must use the same certificate to sign and publish updates for this app.

    To generate an author certificate,

    • Using the Galaxy Watch Designer, from the main menu bar, click Project > Author Certificate. For more information, see Getting Started.

    Important! Make a backup of your author certificate, save the backup on a different device, and keep both the original and backup in a secure place. If you lose your author certificate, you will not be able to publish updates to your apps.

    For more information about author certificates, see Getting the Certificates.

  • .A

    If you have lost your author certificate and do not have a backup or if you have forgotten the password for the certificate and cannot reset it, do the following:

    1. 1. Generate a new author certificate.

    2. 2. Make a backup of your new author certificate and do not save the backup on the same device as the original certificate. Keep both the original and backup in a secure place.

    3. 3. Build a newer version of your app with the new certificate.

    4. 4. Upload the app to Seller Office and release it.

    5. 5. Suspend the older version of the app.

    This is usually due to certification not being performed correctly. Perform the certification process again in this order: Distributor -> certification -> Build -> Run on device.

    *Distributor certification can be performed in this order: Menu bar > Project > Distributor Certificate.
    *If you have reset or otherwise changed your device, you need to perform the distributor certification again.

  • .A

    The distributor certificate is used for signing and verifying your app. It identifies the distributor (for example, Galaxy Store) and grants privileges to that distributor. For testing purposes, it ensures that your signed application is installed on registered devices only.

    In order to test your app on a device, the device must be registered in your personal distributor certificate. Then, you must build your app, which signs the app using your personal distributor certificate.

     

    To generate a personal distributor certificate and register a Samsung device,

    • Using the Galaxy Watch Designer, from the main menu bar, click Project > Distribute Certificate. For more information, see Getting Started.

    The personal distributor certificate is used for testing only. When you release your app for sale in the Galaxy Store, your personal distributor certificate is replaced by an official distributor certificate.

     

    If you upgrade a registered device (for example, you upgrade the Tizen OS), you may need to re-register the device in your personal distributor certificate. For example, if you upgrade your Gear 3 or Sport watch to Tizen 4.0, you must re- register the device in your personal distributor certificate and rebuild your app before testing it on the device.

     

    You may encounter one of the following error messages if there is a problem with the distributor certificate.

    Message Cause Solution

    Account in device profile mismatch with distributor certificate.

    The device has been upgraded and the DUID (Device Unique Identifier) has changed.

    Re-register the device in your personal distributor certificate and rebuild your app.

    Launching AppManagerAppID has encountered a problem.

    The device is not found in your personal distributor certificate or your personal distributor certificate was not created properly.

    Register the device in your personal distributor certificate or re-create your personal distributor certificate and rebuild your app.

    The application installation on the device has failed due to a signature error! (error code : -12)

    You used the Tizen Studio distributor certificate when building your app, not the distributor certificate generated by the Samsung Certificate Extension.

    Select or create a distributor certificate for your Samsung device using the Certificate Manager and rebuild your app.

    For information about the Samsung Certificate Extension, see Installing Certificate Extension. For information about the Certificate Manager, see Creating Certificates and Managing Certificate Profile.

    For more information about distributor certificates, see Getting the Certificates.

    *Initial firmware only

    Here are a few suggestions to help you identify the problem.

    1. The watch device must be in debug mode.
    2. Bluetooth must be turned off. (Initial firmware only)
    3. Your author/distributor certification must be activated correctly.
    4. Your PC/Mac must be connected to the same access point as the watch.
    - Make sure that the first 9 digits of the IP addresses are the same
    : e.g. PC/Mac = 111.111.111.99
    Watch = 111.111.111.xxx
    5. Wake up your watch device, then scan again.
    6. Reboot the watch, then scan again.

    A. When you create a new watch face app, you must create two separate .tpk files: one for Galaxy Watch (Tizen 4.0 and above), and another for Gear S3 and older devices (Tizen 3.0 and below).

    A. Build two .tpk files

    You must build twice. For each build, set a different target API version, and enter a different version number.

    1. Build two .tpk files: one for Galaxy Watch (Tizen 4.0 and later) and one for older Gear models (Tizne 3.0 and earlier). In the build settings, make sure that.
    -Both .tpk files must have the same package name.
    -Both .tpk files must have their own version numbers.
    -Both .tpk files must have their own target API versions (one 3.0 and below, and the other 4.0 and above).

    2. In File browser, note the two different .tpk files that were generated.

    B. Upload both files at the same time

    1. Go to https://seller.samsungapps.com and upload the first binary.

    2. Select Add More Binary.

    3. Upload the second binary. At this point, a standard notice about Samsung version policy may appear, which you can disregard.

    Two binaries are now updated. TW4 will be downloaded by Galaxy Watch (Tizen 4.0 and later), and TW3 will be downloaded by Gear S3 or older models (Tizne 3.0 and earlier).

    C. Continue the App Information process

    Enter all required information. The process is the same as before the Galaxy Watch Designer version 1.6.0 release. After you upload the binary files, complete testing and verification, and start your service.
