hello health data the following sections give you fundamentals for developing the samsung health's partner app. check first the development environment for samsung health's partner apps. importing library add the following library to the “libs” folder in your created application project. samsung-health-data-a.b.c.aar health data store connection add a <queries> element in your app manifest. <manifest . . . > <queries> <package android:name="com.sec.android.app.shealth" /> </queries> </manifest> connect to the health data store with healthdatastore. public class mainactivity extends activity { public static final string app_tag = "simplehealth"; private static mainactivity minstance = null; private healthdatastore mstore; private healthconnectionerrorresult mconnerror; private set<permissionkey> mkeyset; @override public void oncreate(bundle savedinstancestate) { // ... minstance = this; mkeyset = new hashset<permissionkey>(); mkeyset.add(new permissionkey(healthconstants.stepcount.health_data_type, permissiontype.read)); // create a healthdatastore instance and set its listener mstore = new healthdatastore(this, mconnectionlistener); // request the connection to the health data store mstore.connectservice(); } you can end the health data store connection when the activity is destroyed. @override public void ondestroy() { mstore.disconnectservice(); super.ondestroy(); } the connection result is sent to healthdatastore.connectionlistener. if it succeeds, acquiring data permission or querying data will be available. private final healthdatastore.connectionlistener mconnectionlistener = new healthdatastore.connectionlistener() { @override public void onconnected() { log.d(app_tag, "health data service is connected."); healthpermissionmanager pmsmanager = new healthpermissionmanager(mstore); try { // check whether the permissions that this application needs are acquired // request the permission for reading step counts if it is not acquired // get the current step count and display it if data permission is required // ... } catch (exception e) { log.e(app_tag, e.getclass().getname() + " - " + e.getmessage()); log.e(app_tag, "permission setting fails."); } } @override public void onconnectionfailed(healthconnectionerrorresult error) { log.d(app_tag, "health data service is not available."); showconnectionfailuredialog(error); } @override public void ondisconnected() { log.d(app_tag, "health data service is disconnected."); } }; the connection to the health data store can fail and you can check its error result through onconnectionfailed(). if there is an error, an application checks whether the health framework provides a solution with hasresolution() and calls resolve(). if the health framework provides its solution, resolve() makes an application move to one of the following page without a dialog message: app market's samsung health page to install or update it device's settings page to make samsung health available samsung health user's agreement page an application needs to show a proper message for each error case and call resolve(). private void showconnectionfailuredialog(healthconnectionerrorresult error) { alertdialog.builder alert = new alertdialog.builder(this); mconnerror = error; string message = "connection with samsung health is not available"; if (mconnerror.hasresolution()) { switch(error.geterrorcode()) { case healthconnectionerrorresult.platform_not_installed: message = "please install samsung health"; break; case healthconnectionerrorresult.old_version_platform: message = "please upgrade samsung health"; break; case healthconnectionerrorresult.platform_disabled: message = "please enable samsung health"; break; case healthconnectionerrorresult.user_agreement_needed: message = "please agree with samsung health policy"; break; default: message = "please make samsung health available"; break; } } alert.setmessage(message); alert.setpositivebutton("ok", new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int id) { if (mconnerror.hasresolution()) { mconnerror.resolve(minstance); } } }); if (error.hasresolution()) { alert.setnegativebutton("cancel", null); } alert.show(); } see the health data store for more information. permission request the meta-data element for the required data permission value in manifest works with the permission request api. if you want to request data permission for reading the step count, write its value in your application project's manifest as the following example. see privacy check flow in privacy. <application <meta-data android:name="com.samsung.android.health.permission.read" android:value="com.samsung.health.step_count" /> </application> create a permission key set and add a permission key for reading the step count. public class mainactivity extends activity { private set<permissionkey> mkeyset; @override public void oncreate(bundle savedinstancestate) { // ... mkeyset = new hashset<permissionkey>(); mkeyset.add(new permissionkey(healthconstants.stepcount.health_data_type, permissiontype.read)); // connect to health data store } and call healthpermissionmanager.requestpermissions() with its listener. private final healthdatastore.connectionlistener mconnectionlistener = new healthdatastore.connectionlistener() { @override public void onconnected() { log.d(app_tag, "health data service is connected."); healthpermissionmanager pmsmanager = new healthpermissionmanager(mstore); try { // check whether the permissions that this application needs are acquired map<permissionkey, boolean> resultmap = pmsmanager.ispermissionacquired(mkeyset); if (resultmap.containsvalue(boolean.false)) { // request the permission for reading step counts if it is not acquired pmsmanager.requestpermissions(mkeyset, mainactivity.this).setresultlistener(mpermissionlistener); } else { // get the current step count and display it // ... } } catch (exception e) { log.e(app_tag, e.getclass().getname() + " - " + e.getmessage()); log.e(app_tag, "permission setting fails."); } } // ... }; if requestpermissions() is called successfully, the permission ui is popped up to the user. the user's permission information is saved by selecting "done" after the user allows each data permission. and it is received through healthresultholder.resultlistener. private final healthresultholder.resultlistener<permissionresult> mpermissionlistener = new healthresultholder.resultlistener<permissionresult>() { @override public void onresult(permissionresult result) { log.d(app_tag, "permission callback is received."); map<permissionkey, boolean> resultmap = result.getresultmap(); if (resultmap.containsvalue(boolean.false)) { // requesting permission fails } else { // get the current step count and display it } } }; } see the health permission manager for more information.

health data store the sdk provides the health data store to access the health data with a user’s consent. the data in the health data store can be shared with other partner apps also. preparing data access an application needs to connect the health data store, and acquire data permission to access the data in the health data store. the following figure shows a basic flow for working with samsung health. in case of connection failure, all exceptions should be handled clearly with a proper message to the user. it helps to prevent unexpected operations on your application. for detailed code, see: app manifest health data connection snippet acquiring data permission snippet health data query healthdataresolver helps to access the data with apis of the following figure. all queries except inserting data can be requested through a filter to set the target range for a query. a data query is sent asynchronously or synchronously. asynchronous query is used usually and you can select one of the methods for your need. see the following examples for more information. asynchronous data query synchronous data query the query result is retrieved as the following table. request result insert()update()delete() baseresult read() readresult aggregate() aggregateresult see data query snippets in api reference. filter healthdataresolver.filter is very useful to clear the data range for reading, updating, and aggregating health data. multiple filters can be combined with: and() or() see more descriptions in api reference. data normalization the health data is stored based on the normalized unit as defined in international system of unit (si) in the following table. item unit height cm weight kg temperature celsius blood glucose mmol/l blood pressure mmhg hba1c % spo2 % calorie kcal speed m/s distance meter time millisecond water intake ml caffeine intake mg data normalization enables your application to read health data without the specific unit. it means that you should be careful to unify the data units when inserting health data to the health data store. healthdataunit helps to convert data value between different units. converting unit

design inspiration is all around us; however, tapping into it is another story. fortunately, there are members of the samsung developers community who’ve cracked the code and defeated ‘designer’s block.’ we connected with several watch faces/themes designers and are excited to share their advice, creative processes, and sources of design inspiration in this blog series. this week, we’re featuring pedro machado from health face. a designer from spain, pedro focuses on creating sport watch faces designed for daily use. read on to learn about how he got into designing watch faces and how he finds inspiration for his stylish and functional designs. when and why did you start designing watch faces? in 2017, i read a news story from samsung promoting the design of watch faces and that explained some features of the galaxy watch studio program (formerly galaxy watch designer). afterwards, i was curious to try designing my own personalized watch face, since a few months prior my parents gave me a samsung smartwatch. i found watch face design interesting and started research on how i could start creating designs for others to enjoy on their devices. what does your design process look like? do you have a strict protocol or is it more free flowing? i like to use my free time as a chance to get inspired and come up with ideas that i can later transform into a design. once i have several ideas in mind, i put them on paper to see the possible combinations and shapes they can take on a watch. when the idea is clear or almost ready, i start preparing the design on my computer. once i have all the elements created, i mount my design in gws and test it on 4-5 devices to check that everything works correctly. how has your design approach evolved over time? in the beginning, i created varied designs of all styles, from formal and minimalist to fun with many patterns. however, after a year of experience and analyzing statistics, i concluded that sport designs that take advantage of watch characteristics are received well by users. that’s when i decided to create health face, focused on sports and daily life that many users can identify with and use to get the information they need. what was the inspiration for your most successful watch face and how did you make it a reality? i remember being inspired to create one of my most successful watch faces at the sdc19 conference in san josé, california. there was a prototype car with some very striking speed markers that gave me the idea to design a watch face with similar markers – i also thought it would contrast well with smart devices. health face nº58 how do you strike a balance between the vision you have for a watch face and its functionality? is this the most challenging part of the design process? i agree that this part is the most challenging, since sometimes an idea is difficult to translate to the screen. plus, there’s the added consideration of the user. if they have vision problems, they might need larger letters and numbers, and this can pose a challenge to your original idea. to achieve a good balance between the initial idea and the final product, it’s important from the beginning to think about all the possible errors or obstacles you may encounter with your design. that way, if any problem arises, they will likely be small and easy to solve. how do you navigate guidelines without compromising the integrity of your design? when you’re starting out, it’s impossible to know all the restrictions. you must be patient with yourself and learn from your experiences. eventually you’ll learn how to navigate those guidelines and create great designs. what’s the one piece of advice you’d give a designer who is stuck in a creative rut? my advice to a designer who can’t think of a new design is to not get overwhelmed by the lack of inspiration. i recommend disconnecting for an afternoon. go outside, play a sport, relax and clear your mind to help free space for new ideas. the world around us is constantly sending signals and clues to make new designs, so take advantage of it! thanks to pedro for sharing helpful advice on the design process, staying creative and finding inspiration for galaxy watch face designs. you can connect with pedro and health face on instagram, twitter, and facebook. designers, are you ready to take the next step and sell your work on samsung devices? submit your galaxy watch faces or themes portfolio before the submission window closes on february 23rd. stay tuned for the final installment in our ‘prime time design’ series featuring ramon campos from friss in motion and follow us on twitter at @samsung_dev for our latest updates.
