FAQ

faq q01 if i create a watch face using watch face studio, is it supported on all wear os watch devices? watch face studio is compatible with all wear os watch devices running api level 30 and higher if you create a watch face in watch face studio, you can use it on all wear os watch devices, regardless of manufacturer however, because of limitations with deprecated apis, your watch face may not be available on devices that are still using deprecated apis the galaxy watch studio serves tizen’s galaxy watch 1, 2, and 3 q02 does watch face studio support all types of watch face shapes, including circular and square? in watch face studio, the watch shape is set to a circle by default to support other watch face shapes, disable the apply circular crop option in the watch face canvas properties when circular crop is disabled, the watch face shape is determined by the user’s device to ensure watch face components display correctly, avoid placing components directly on the edges of the watch face the image can shift on some devices to prevent screen burn-in watch face studio creates a project with a single screen resolution, but the created watch face supports all device resolutions q03 how can i design my watch face to save battery? you can reduce battery usage through the following strategies use darker colors on the watch face make sure the images are fitted to the screen make sure you have removed all unused layers before building the watch face package for more information, see performance tips q04 how can i improve the performance of my watch face? using too many components in your watch face can degrade the performance of the watch face and consume the device battery more to optimize the use of components make sure fewer than 8 complications are visible in both ambient and normal modes make sure there are no hidden layers in either ambient or normal modes q05 how does my watch face work in always-on ambient mode? the second hand is not supported in ambient mode design your watch face to hide the second hand in ambient mode the on-pixel ratio opr varies between device models to find the opr for a specific device, check the device specification to examine the on-pixel performance of your design in ambient mode for various device shapes, in the run preview, select analyze you can also analyze the on-pixel performance for circular devices when you use the run on device and publish features in watch face studio q06 how can i enable users to customize their watch face? to enable watch face customization, define themes and styles for the watch face in the style property window the user can select from the themes and styles you have defined you can define a theme color palette and apply those colors to the component layers you can also implement multiple images for the analog hands, image, multimedia, and index components remember to give each component and style a clear, descriptive name the names appear when the user uses the customize mode to personalize their watch face you can also implement localized component names using text ids for more information, see project settings q07 what is the difference between the step counter tag expressions [sc], [sc_per], and [sc_goal]? the [sc] tag is the measured step count the [sc_goal] tag represents the step goal the user’s step goal can be synchronized from a supported health application, or you can define a step goal for the watch face to configure the step goal for your watch face, in wfs, go to file > project > settings > health the [sc_per] tag is the percentage of the step goal achieved, automatically calculated from the step count and step goal q08 how do i sell my watch face in a region that is not supported by the play store? watch faces can be sold in unsupported countries through the device manufacturer’s own app store for example, watch faces for galaxy watch can be sold through galaxy apps for more information, see galaxy store seller portal different app stores can support different file types for watch faces, such as apk or aab you must create the appropriate watch face package for each store q09 why can't i find the 'enable debugging over the bluetooth' setting in galaxy wearable application on my phone? check that your wearable device supports bluetooth debugging debug over bluetooth is not supported on wear 3 devices for more information, see debug over bluetooth q10 why can’t i use lottie multimedia files on my watch face anymore? lottie files are no longer supported since watch face studio version 1 4 13 you must replace them with animations in a supported format, such as webp or animated gif q11 how does the step goal "sync to device" feature work? the sync to device feature enables your watch face to use the step goal defined by the user on their device’s health application it is supported on watch devices running api level 33 and higher wear 4 and later on wear 3 devices, because sync to device is not supported, the step goal is fixed to 6000 if you want to set a different step goal for wear 3 devices, you must create a separate watch face version for wear 3, disable sync to device, and define the step goal directly q12 why are some heart rate tag expressions and features not supported for my watch face? some tag expressions and features related to measuring heart rate on wear os watch devices running api level 30 are not supported by watch face studio v1 4 13 however, wfs supports synchronizing the measured heart rate value with the value displayed on the screen on wear os watch devices running api level 33 and higher and galaxy watch devices for wear os powered by samsung, the open app feature supports opening the health application to view heart rate information on those devices q13 why can't i group a complication slot with other components or combine multiple complications? in watch face studio, complications must be implemented independently they cannot be grouped with or be part of another element complications can only contain elements within them

Payment Card Push Provisioning Using Samsung Pay SDK

samsung has invested tremendous effort in the digital economy from the very beginning and continuously facilitates millions of people who use samsung wallet. samsung wallet is one of the most used digital wallets right now in the cashless industry. it is a medium that fuels up digital currency transactions by its ease-of-use and security. to support various businesses, samsung has developed the samsung pay sdk which allows you to use samsung wallet’s features effortlessly. the samsung pay android sdk consists of android-based apis to perform transactions using samsung wallet. it helps to implement simple payment solutions, which boost your businesses' growth to the next level. to understand the business and possibilities, visit the samsung pay sdk portal for more information. what is push provisioning? push provisioning is one of the major features of the samsung pay sdk. it allows an issuer bank to push the payment experience to a digital wallet. it simplifies the process of adding a payment card as it can be done with a single tap of a finger. the normal process is time consuming since it involves multiple steps, and the user needs to enter their card information. with push provisioning, the process is easier as it can be done with a single tap, and it's also secure because the process is performed from the issuer application. this tutorial demonstrates how to implement the push provisioning feature in an issuer application with the samsung pay sdk. figure 1: samsung pay push provisioning concept prerequisite to use the samsung pay sdk, you must be an official samsung partner. for information about the partnership process, see the samsung pay member guide. as a samsung pay sdk partner, you can utilize this tutorial while implementing push provisioning. sdk integration to download the samsung pay sdk, go to samsung developers portal > samsung pay > download . when the download is complete, a .jar file called “samsungpaysdk_x.xx.xx_release.jar” can be found under the libs folder. add the samsung pay sdk .jar file to the libs folder of your android project using android studio or file explorer. navigate to the build.gradle file of your application module and enter the following dependency to the dependencies block: implementation files('libs/samsungpaysdk_x.xx.xx_release.jar') if the target sdk version is 30 or higher (android 11 or r-os), include the following <queries> element in androidmanifest.xml. for more information, see declare package visibility needs. <queries> <package android:name="com.samsung.android.spay" /> </queries> since we are using the latest sdk, set the api level to 2.18. we recommend using the updated version of the samsung pay sdk for a better user experience. implement the following code in the <application> element of androidmanifest.xml: <meta-data android:name="spay_sdk_api_level" android:value="2.18" /><!-- most recent sdk version is recommended to leverage the latest apis--> configure the debug or release mode for your project as follows: for testing and qa, set the debug mode value to y. this mode requires the allowed samsung account(s) list to test. for market release to end users, set the debug mode value to n. <meta-data android:name="debug_mode" android:value="n" /><!--set to y if debug mode--> let’s get started since the main functionalities in this tutorial are based on push provisioning, we need to initialize the samsungpay and cardmanager classes first. these two classes take the same parameters to construct, which are context and an instance of the partnerinfo class. the partnerinfo object contains information about partners, which is to validate the request from the issuer application. private val partnerinfo = partnerinfoholder.getinstance(context).partnerinfo private val samsungpay= samsungpay(context,partnerinfo) private val cardmanager = cardmanager(context, partnerinfo) check if samsung wallet is ready since the samsung pay sdk depends on samsung wallet, you need to ensure that samsung wallet is prepared for transactions. check the samsung wallet status before the sdk api call using the getsamsungpaystatus() method. if you get the "spay_ready" status, you can proceed further to call any api. for more details, see the programming guide. samsungpay.getsamsungpaystatus(object : statuslistener { override fun onsuccess(status: int, bundle: bundle?) { if(status == spaysdk.spay_ready){ //enable samsung pay sdk functionalities } else{ //disable samsung pay sdk functionalities } } override fun onfail(status: int, bundle: bundle?) { //disable samsung pay sdk functionalities } }) check if the card is added during development, you may need to know whether the card is already added to samsung wallet or not. to get a list of cards that have already been added to the wallet, use the getallcards() method. for card-related operations, such as getting cards from samsung wallet, the cardmanager class is the responsible one to perform. this means that the getallcards() method is a property of the cardmanager class. this method takes a bundle and an interface as parameters, so it returns the result based on the operation. notethe getsamsungpaystatus() method must be called before the getallcards() method. the getallcards() method cannot return a card list if the getsamsungpaystatus() method responds with a code other than spay_ready. tipone of the most common issues during development is that the getallcards() method returns empty data even though a card has been added. the main reason for this issue is that the card issuer name and issuer name on the samsung pay portal are not the same. for more information, see the faq & troubleshooting page. val getcardlistener: getcardlistener = object : getcardlistener { override fun onsuccess(cards: list<card>) { //show cards } override fun onfail(errorcode: int, errordata: bundle) { //show error } } cardmanager.getallcards(null, getcardlistener) configure your payload the getwalletinfo() method is designed to request wallet information from the samsung wallet application prior to performing the add card operation. wallet information can be mandatory or optional for token providers for payload configuration. for visa, wallet information is mandatory, and you have to use it while building the payload. val keys = arraylist<string>() keys.add(samsungpay.wallet_dm_id) keys.add(samsungpay.device_id) keys.add(samsungpay.wallet_user_id) val statuslistener: statuslistener = object : statuslistener { override fun onsuccess(status: int, walletdata: bundle) { val deviceid: string? = walletdata.getstring(samsungpay.device_id) val walletaccountid: string? = walletdata.getstring(samsungpay.wallet_user_id) //build payload } override fun onfail(errorcode: int, errordata: bundle) { //show error } } samsungpay.getwalletinfo(keys, statuslistener) complete the push provisioning the last command to execute the push provisioning operation in our tutorial is the addcard() method, which is required to perform the push provisioning in samsung wallet. the payload we have created must be delivered with the addcard() method as a parameter. the payload is a tricky part where partners can sometimes get confused or misguided. to be clear, samsung does not provide the payload for push provisioning. the payload is defined between the issuer and the token provider, and it varies based on different issuers and token providers. samsung only delivers the payload to the token provider without consuming anything. the addcard() method also takes a callback as a parameter to return the result based on the operation. tipfor push provisioning of a payment card, samsung pay does not store any card information nor provide any payload for adding cards. so, the issuer needs to provide the payload in a format that is defined in the token provider specification. the issuer and the token provider have their own agreement of data sharing, payload, and encryption. samsung pay is only a medium for this process. val tokenizationprovider = addcardinfo.provider_abcd val carddetail = bundle() carddetail.putstring(extra_provision_payload, payload) var cardtype = card.card_type_credit_debit val addcardinfo = addcardinfo(cardtype, tokenizationprovider, carddetail) val addcardlistener: addcardlistener = object : addcardlistener { override fun onsuccess(status: int, card: card) { //show successful message } override fun onfail(errorcode: int, errordata: bundle) { //show error } override fun onprogress(currentcount: int, totalcount: int, bundledata: bundle) { //extra event for operation count } } cardmanager.addcard(addcardinfo, addcardlistener) summary push provisioning is the powerful experience of sharing information to a digital wallet, and digital wallets transform this experience to the next level by facilitating transactions within seconds. samsung wallet handles these operations and helps the digital payment system to its next step. for more information about the samsung pay sdk, visit the samsung pay developers portal. if you face any issues during sdk implementation, contact the developer support team.

Hello World in C

hello world in c importantdue to nacl deprecation by the chromium project, tizen tv will continue its support for nacl only until 2021-year products meanwhile, tizen tv will start focusing on high-performance, cross-browser webassembly from 2020-year products this topic describes the "hello world in c" sample application implementation samples hello world in c this tutorial describes how to implement a simple "hello world" native client nacl application in c the nacl module waits for a message from the javascript component, creates a reply message by appending the received string to a predefined string, and sends it as a reply back to the javascript component, which displays the message on the screen the following figure shows the sample application when the nacl module has loaded, the "status" field text changes to "loaded" in the "nacl messages" section, the message "echo from nacl hello world from js" appears for information on how to access the sample application cheat sheet and run the application, see sample-based tutorials to implement the "hello world" nacl application in c initialize the module a nacl module in c must implement the following 2 functions the ppp_initializemodule function is an entry point for the nacl plugin and is called when the module is loaded on the web page you must initialize interfaces and resources in this function, including the following mandatory interfaces the ppb_messaging interface implements the postmessage function, which allows the nacl plugin to send messages to the javascript component this interface is used to send the reply message to the javascript component the ppb_var interface creates and manages pp_var objects, which are wrappers for javascript variables in c code this interface is used to convert c-style strings to javascript variables, which can be sent to the javascript component using the ppb_messaging interface /* global pointers to selected browser interfaces */ const ppb_messaging* g_messaging_interface; const ppb_var* g_var_interface; /** * entry point to the nacl module, called while the module is being initialized * this function is obligatory; initialize interfaces in this function */ pp_export int32_t ppp_initializemodule pp_module module_id, ppb_getinterface get_browser_interface { // initialize pointers to used browser interfaces g_messaging_interface = const ppb_messaging* get_browser_interface ppb_messaging_interface ; g_var_interface = const ppb_var* get_browser_interface ppb_var_interface ; return pp_ok; } the ppp_shutdownmodule function is used internally by google chrome™ and must be left empty /** * implementation-specific function for internal use only * this function is obligatory, but leave it empty * @see <code>ppp_shutdownmodule</code> in ppp h file */ pp_export void ppp_shutdownmodule { } for more information on the above functions, see the "include/ppapi/c/ppp h" file in your "nacl_sdk/pepper_xx" directory importantto compile the nacl code successfully, the ppp_initializemodule and ppp_shutdownmodule functions must be implemented with these exact names implement the instance-specific functions when developing a nacl application in c, you must implement all the following functions specific to the ppp_instance interface, even if they are empty in the instance_didcreate function, define the actions to perform when the instance is created, such as its initialization logic the function returns pp_true if the instance creation was successful, or pp_false otherwise in the sample application, no initialization logic is needed, so the function always returns pp_true static pp_bool instance_didcreate pp_instance instance, uint32_t argc, const char* argn[], const char* argv[] { return pp_true; } in the instance_diddestroy function, define the actions to perform when the instance is destroyed, such as releasing any acquired instance-specific resources in the sample application, the instance has nothing to release, so the function is empty static void instance_diddestroy pp_instance instance { } in the instance_didchangeview function, define the actions to perform when the application viewport is created or changed in any way the sample application does not use graphics, so the function is empty static void instance_didchangeview pp_instance pp_instance, pp_resource view { } in the instance_didchangefocus function, define the actions to perform when the embedded nacl module gains or loses focus this functionality is not needed in the sample application, so the function is empty static void instance_didchangefocus pp_instance pp_instance, pp_bool has_focus { } the instance_handledocumentload function is not used in tizen nacl applications, and must return pp_false static pp_bool instance_handledocumentload pp_instance pp_instance, pp_resource pp_url_loader { return pp_false; } for more information on the above functions, see the "include/ppapi/c/ppp_instance h" file in your "nacl_sdk/pepper_xx" directory to receive messages, implement the messaging_handlemessage function of the ppp_messaging interface when the nacl module receives a message from the javascript component extract the message from the pp_var object concatenate the message to the predefined echo string, using the c standard library snprintf function convert the char buffer to a pp_var object using the ppb_var interface send the message to the javascript component using the postmessage function of the ppb_messaging interface const char* kecho = "echo from nacl "; /** * handles messages from js sent by the nacl_module postmessage function */ void messaging_handlemessage pp_instance instance, struct pp_var message { char str_buff[64]; uint32_t len; // extract the char array from the message pp_var structure const char* message_str = g_var_interface->vartoutf8 message, &len ; if message_str == null return; snprintf str_buff, sizeof str_buff , "%s%s\n", kecho, message_str ; // create a pp_var containing the message body struct pp_var var_response = g_var_interface->varfromutf8 str_buff, strlen str_buff ; // post the message to the javascript layer g_messaging_interface->postmessage instance, var_response ; } for more information on the handlemessage function, see the "include/ppapi/c/ppp_messaging h" file in your "nacl_sdk/pepper_xx" directory connect the interfaces to the nacl module to connect the implemented interfaces, you must implement the ppp_getinterface function, which takes a c-style string as a parameter and returns a const void pointer the function is called multiple times during application initialization, checking for ppp interfaces that have been implemented for each implemented interface, return a structure containing pointers to the interface functions /** * this mandatory function retrieves the interface implementations that this module supports */ pp_export const void* ppp_getinterface const char* interface_name { if strcmp interface_name, ppp_instance_interface == 0 { // the module must fill this structure interface in the following order // and return it in this case static ppp_instance instance_interface = { &instance_didcreate, &instance_diddestroy, &instance_didchangeview, &instance_didchangefocus, &instance_handledocumentload }; return &instance_interface; } if strcmp interface_name, ppp_messaging_interface == 0 { // to handle messages, implement the ppp_messaging interface and // return it as a pointer to this structure static ppp_messaging messaging_interface = { &messaging_handlemessage }; return &messaging_interface; } return null; } for more information on the ppp_getinterface function, see the "include/ppapi/c/ppp h" file in your "nacl_sdk/pepper_xx" directory
