DISTRIBUTION OF TIZEN-BASED WATCH APPS HAS BEEN DISCONTINUED
Use the Samsung Accessory Protocol (SAP) API
To use the SAP API, change some configurations in your application project:
-
Add the Accessory Service Profile.
Communicating with an Android application requires a declaration of descriptions about the Accessory Service Profile. The profile is declared in a separate XML file in the
/res/xml
folder of the application project. The actual path of the XML file can be described with ‘meta data’ in theconfig.xml
file.A. Add the
accessoryservices.xml
file in the/res/xml
folder.For an example file, see the following sample Accessory Service Profile. You can modify the id value of the
serviceProfile
element to define your application. The id value must be unique globally and it is also used in the Android side application to identify the service profile.Note :The service profile ID must start with ‘/’, followed by [0-9], [a-z], ‘_’, and ‘/’ (as delimiter). The maximum length is 30 characters. For more information about the XML file, see this.
```xml
<resources>
<application name="MyApplication">
<serviceProfile id="/org/example/myapp/my_message" name="MyMessage"
role="consumer" version="1.0">
<supportedTransports>
<transport type="TRANSPORT_BT"/>
<transport type="TRANSPORT_WIFI"/>
</supportedTransports>
<serviceChannel id="110" dataRate="low" priority="low"
reliability="enable">
</serviceChannel>
</serviceProfile>
</application>
</resources>
```
B. Add meta data to define the Accessory Service Profile XML file location.
Open the `config.xml` file in the Web application configuration editor, select the **Tizen** tab. In the Meta data section, click **Add**, define the key as **AccessoryServicesLocation** and the value as **/res/xml/accessoryservices.xml**, and click **OK**.

config.xml
file.Open the
config.xml
file in the Web application configuration editor, select the Privileges tab, and click Add.Add the privilege and click OK.
