SDK Emulator

• Screen resolutions support • 320x320 Gear 1, Gear 2, Gear 2 Neo • 360x480 Gear S

• Control Panel Managers • Device • App

Application Development

• Requirements • Samsung Account (sign up at http://developer.samsung.com) • Tizen SDK for Wearable

• Connect real device to IDE or use Emulator • Create first application (template or sample apps)

Acquiring a certificate

• Sign up or create an account on http://developer.samsung.com • Request certificates for Author and Device

• New certificate • Based on existing certificate • Based on existing Android Certificate

Security Profile

• Get DUID (Device Unique Identifier)

Apply certificate to Security Profile

SAP requirements add privilege in config.xml

• Wearable / Gear device

• Mobile / Android

<tizen:privilege name="http://developer.samsung.com/privilege/accessoryprotocol"/>

<tizen:privilege name="http://developer.samsung.com/tizen/privilege/accessoryprotocol"/>

Consumer and Provider roles accessoryservices.xml

• Define roles

• Link service profile

<resources> <application name = "myApplication"> <serviceProfile role = "consumer" name = "myApplication" id = "/system/myApp" version = "2.0" serviceLimit = "ONE_PEERAGENT" serviceTimeout = "30"> <supportedTransports> <transport type = "TRANSPORT_BT"/> </supportedTransports> <serviceChannel id = "100" dataRate = "high" priority = "low" reliability = "enable"/> </serviceProfile> </application> </resources>

Time API

var date = tizen.time.getCurrentDateTime(); // instead of new Date() var hours = date.getHours(); var minutes = date.getMinutes(); var seconds = date.getSeconds(); console.log(hours + ":" + minutes + ":" + seconds); var changeCallback = function() { var currentDateTime = tizen.time.getCurrentDateTime(); console.log(currentDateTime.toLocalString()); }; tizen.time.setDateTimeChangeListener(changedCallback); // tizen.time.unsetDateTimeChangeListener();

Power API

Resource State

MEMORY

tizen.systeminfo.getPropertyValue(property, successCallback, errorCallback); var listenerId = tizen.systeminfo.addPropertyValueChangeListener(property, successCallback, options); tizen.systeminfo.removePropertyValueChangeListener(listenerId);

Application API

// all installed applications tizen.application.getAppsInfo(onSuccess, onError); // details about Calendar application var appInfo = tizen.application.getAppInfo("com.samsung.w-calendar2"); // all running applications tizen.application.getAppsContext(onSuccess, onError); // current application context var appContext = tizen.application.getAppContext(null);

Application API

// launch an application tizen.application.launch("com.samsung.w-calendar2", onSuccess, onError); // run an application to choose image files var onAppReply = { onsuccess: function(data) { for (var i = 0; i < data.length; i++) { if (data[i].key === "http://tizen.org/appcontrol/data/selected") { console.log("Selected image: " + data[i].value[0]); } } }, onfailure: function() { console.log("The launch application control failed"); }, } var appControl = new tizen.ApplicationControl( "http://tizen.org/appcontrol/operation/pick", // operation null, // URI "image/jpeg", // mime null); // category ); tizen.application.launchAppControl(appControl, null, onSuccess, onError, onAutoReply);

Development on real device

• Connect Android device to PC via Bluetooth • Debugging by Remote (Web) Inspector

Working with SDK Emulator

1. Uninstall Samsung Gear Manager from mobile device 2. Download and unzip Applications_for_Emulator.zip 3. Install the following APKs on mobile device:

• SAaccessoryService_Emul.apk • SAFTCore_Emul.apk • HostManagerForEmul.apk

4. Run an app HostManagerForEmul on mobile device

Connecting Host with SDK Emulator

Requirements 1. ADT, adb and set a path to adb*

export PATH=${PATH}:~/adt-bundle/sdk/platform-tools adb devices

2. Tizen SDK for Wearable 3. Type commands in terminal

adb –d forward tcp:8230 tcp:8230 4. Run an app HostManagerForEmul 5. Run SDK Emulator * Make sure USB debugging mode is turned on

Removing an app from SDK Emulator

• Set a path to sdb, and make sure it’s properly set export PATH=${PATH}:~/tizen-wearable-sdk/tools sdb devices

• Type the following command in terminal sdb uninstall [appid] i.e. VbsgE6bms2
