Overview
A device resource package, which is presented in .zip format, contains image resources, text
resources, a device capability profile, and a device presentation profile. It is used to configure
the capabilities and presentation of a smart home device. Each smart home device has only
one resource package, which is identified by the manufacturer ID and model of the device.
Related Concepts

App default template
The App default template is a template to be used by Huawei HiHo App by default, and
defines the default layout of device details. The default layout includes a title bar, a
secondary area, a master area, an event area, and a command area from top to bottom.
Templates are available for all of the master area, secondary area, and command area.
Developers can customize the properties and commands of corresponding areas based on
the templates. A template is a customization of properties or commands.

Master area
This area displays the properties of master services. It may include multiple pages.

Secondary area
This area displays the properties of secondary services on only one page on which at
most six properties can be displayed.

Event area
This area displays historical events. It, however, displays only the last historical event.
You can click the event area to check all historical events of the current device in a
device event list.

Command area
This area displays commands. It may include multiple pages.
Development Process
For details on steps (1) to (5), see the five sections in chapter "Developing the Device
Resource Package."

device resource package is ContactSensor_0001_0002-0003.zip, where ContactSensor
indicates the device type (devicetype), 0001 indicates the manufacturer ID (manufacturerId),
and 0002-0003 indicates the device model (model).
Root directory of resource files, such as /data/data/{appPackageName}
└res_{manufacturerId} Manufacturer resource directory, such as res_0001

It is recommended that the technical engineer should write the device capability profile and
the service capability profile with reference to Huawei IoT Device Capability Profile
Development Guide.docx.

For details on the contents of the device capability profile and service capability profile, see chapter
"Sample Device Resource Package" and Huawei IoT Device Capability Profile Development
Guide.docx.

The developer shall determine whether to add a device type or service type with reference to Huawei
IoT Device Capability Profile Development Guide.docx.
3.2 Compiling the Device Presentation Profile and Service
Presentation Profile
The presentation profiles, which serve as primary customization of device presentation, will
be used in Huawei HiHo App to make presentation based on Huawei HiHo App default
template.
Device Presentation Profile
Currently, the device presentation profile is not involved; therefore, the developer can simply use a blank
file and does not need to modify it.

3.3 Developing Image Resources
The UCD designer makes image slices according to specifications (such as size and format)
for each image resource.
The UCD designer needs to pay attention to the size of each image file. After all image
resources and files are compressed into the device resource package, the size of the device
resource package cannot be greater than 4 MB.
Issue 01 (2016-09-22)

For details on required image resources, see section "Device Resource Package Structure" and
chapter "Sample Device Resource Package."

For details on the image specifications, see section "Specifications."

3.4 Compiling Text Description Files
Text description files (in .txt format) are involved only in device addition and deletion
processes.
It is recommended that the UCD designer should give text descriptions according to the
maximum number of words in a text description and according to the steps for adding or
deleting the smart home device to be integrated. The text descriptions shall be saved in UTF-8
format. The content of each text description file must correspond to the content of the image
in each step.

For details on the text specifications, see section "Specifications."
3.5 Summarizing and Packaging Resources
After making the resource files as described in the preceding scenario, place the resource files
into the corresponding directory. Use the following method to package the resource files:
1.
Select and right-click all folders in the root directory of the resource package. A shortcut
menu is displayed. Choose Add to archive …from the shortcut menu, as shown in the
following figure.
2.
Select ZIP below Archive format, enter the name of the .zip package (Device
type_Manufacturer ID_Device model.zip), and then click OK. Ensure that the device
type, manufacturer ID, and device model are consistent with the actual situation, with an
underline in between.

3 Developing the Device Resource Package
The developer may read chapter 6 "Common Sensor Ecological Development Guide" in
Huawei IoT Agent Integration Development Guide.docx to determine the device type,
manufacturer ID, and device model.
After making the device resource package, the developer sends it in an email to
[email protected]. The email title shall indicate the information [Device resource
package review] Whether a new device type and service type are added, such as [Device
resource package review] Properties are added to an existing service or [Device resource
package review] New device type and service type are added. Huawei technical support
personnel will complete the review and return feedback information within one working day.

Sample Device Resource Package
Name of the sample device resource package: App Resource Package Demo.zip
Archive path: Demo\ App Resource Package Demo.zip

The device resource package must be in .zip format. In this sample, a contact sensor
(whose device type is ContactSensor) is used as an example. The developer needs to
change the device resource package according to the actual product.

For details on the profiles, image files and text description files involved in the device
resource package and the specifications of images and text, see sections "Device Resource
Package Structure" and "Specifications."

Ensure that the fields manufacturerId, model, and deviceType defined in the
devicetype-capability.json file in the profile\ directory are consistent with the data
reported by the device, and consistent with the devicetype, manufacturerId, and model
in the resource package name {devicetype}_{manufacturerId}_{model}.zip; otherwise, the
App will be unable to search resource files such as the profiles and images according to
the information, the device list and the device details page will fail to display the images
or text descriptions of the resource package, and certain functions of the device will fail.

For details on the service types currently supported, see Huawei IoT Device Capability
Profile Development Guide.docx.

After modifying a profile, the developer can use the online JSON compiler to check
whether the format of the profile is correct. The developer needs to ensure the correctness
of the format of each profile.
