黑莓10系统：手动及编程查询Build No与固件版本方法

Hey there! Let’s walk through how to find the Build No and firmware version for BlackBerry 10 devices—both manually (for end-users) and programmatically (for developers).

Getting this info manually is straightforward, no extra tools required:

• Open the Settings app (look for the gear icon on your home screen)
• Scroll all the way to the bottom and tap About
• On the About page, you’ll immediately see the OS Version (this is your firmware version)
• Keep scrolling down, and you’ll find the Build Number—it’s usually a string combining numbers and sometimes letters, like 10.3.3.3216.1055

If you’re building an app for BlackBerry 10, here’s how to pull these values programmatically, depending on your development stack:

Native SDK (C++/QML) #

QML Implementation #

Use the built-in bb.system module to access device info directly in your QML UI:

import bb.system 1.0

// Example label displaying the values
Label {
    text: "Firmware Version: " + DeviceInfo.osVersion + "\nBuild No: " + DeviceInfo.buildId
}

C++ Implementation #

Use the bb::system::DeviceInfo class to retrieve the values in your C++ backend:

#include <bb/system/DeviceInfo>

// In your code logic
bb::system::DeviceInfo deviceInfo;
QString firmwareVersion = deviceInfo.osVersion();
QString buildNumber = deviceInfo.buildId();

// Use these strings as needed (e.g., log them, display in UI)

WebWorks (HTML5/JavaScript) #

For web-based apps using BlackBerry WebWorks, leverage the blackberry.system API:

1. First, make sure your config.xml includes the required permission:

<feature id="blackberry.system" required="true" version="1.0.0"/>

2. Then call the API in your JavaScript:

// Get firmware version
const firmwareVersion = blackberry.system.getProperty("osversion");
// Get Build No
const buildNumber = blackberry.system.getProperty("buildnumber");

// Log or display the values
console.log(`Firmware: ${firmwareVersion}, Build No: ${buildNumber}`);
