功能使用率对比
二、环境准备
2.1 开通AGC分析服务
登录AGC控制台
进入项目 > 选择应用 > 选择"分析服务"
点击"立即开通"
2.2 添加DevEco Studio依赖
// build.gradle 配置
dependencies {
implementation 'com.huawei.agconnect:agconnect-analytics-harmony:1.8.0.300'
implementation 'com.huawei.agconnect:agconnect-crash-harmony:1.8.0.300'
}
三、设备信息采集
3.1 基础设备信息上报
// DeviceAnalytics.ts - 设备分析服务
import agconnect from '@agconnect/api-harmony';
import '@agconnect/analytics-harmony';
import device from '@ohos.deviceInfo';
export default class DeviceAnalytics {
private static instance: DeviceAnalytics;
private analytics: any;
private constructor() {
this.analytics = agconnect.analytics();
}
public static getInstance(): DeviceAnalytics {
if (!DeviceAnalytics.instance) {
DeviceAnalytics.instance = new DeviceAnalytics();
}
return DeviceAnalytics.instance;
}
// 上报设备信息
public async reportDeviceInfo() {
const deviceInfo = {
deviceType: device.deviceType,
screenWidth: window.width,
screenHeight: window.height,
dpi: window.screenDpi,
osVersion: device.osFullName,
ramSize: device.memorySize
};
this.analytics.setUserProfile('device_profile', deviceInfo);
// 自定义事件：设备激活
this.analytics.onEvent('device_activation', {
device_type: device.deviceType,
screen_resolution: `${window.width}x${window.height}`
});
}
// 上报屏幕切换事件
public reportScreenChange(newSize: { width: number, height: number }) {
this.analytics.onEvent('screen_resize', {
old_size: `${window.width}x${window.height}`,
new_size: `${newSize.width}x${newSize.height}`,
orientation: newSize.width > newSize.height ? 'landscape' : 'portrait'
});
}
}
3.2 鸿蒙5设备能力检测
// DeviceCapabilityDetector.java - 设备能力检测
import ohos.app.Context;
import ohos.system.device.DeviceInfo;
public class DeviceCapabilityDetector {
public static String getDeviceType(Context context) {
DeviceInfo deviceInfo = DeviceInfo.get(context);
switch (deviceInfo.getDeviceType()) {
case DeviceInfo.DEVICE_TYPE_TV:
return "TV";
case DeviceInfo.DEVICE_TYPE_TABLET:
return "Tablet";
case DeviceInfo.DEVICE_TYPE_CAR:
return "Car";
case DeviceInfo.DEVICE_TYPE_WEARABLE:
return "Wearable";
default:
return "Phone";
}
}
public static boolean isLargeScreen(Context context) {
DisplayAttributes attributes = context.getResourceManager()
.getDeviceCapability()
.getDisplayAttributes();
return attributes.width >= 600; // dp
}
public static void reportCapabilities(Context context) {
AGConnectAnalytics.getInstance(context)
.setUserProfile("device_capabilities", getCapabilitiesJson(context));
}
private static String getCapabilitiesJson(Context context) {
JSONObject capabilities = new JSONObject();
try {
capabilities.put("isLargeScreen", isLargeScreen(context));
capabilities.put("touchSupport", hasTouchScreen(context));
capabilities.put("multiWindow", supportMultiWindow(context));
} catch (JSONException e) {
e.printStackTrace();
}
return capabilities.toString();
}
}
四、响应式布局实现
4.1 资源限定词配置
// resources/base/element/device_types.json
{
"screen": {
"phone": {
"maxWidth": 599
},
"tablet": {
"minWidth": 600,
"maxWidth": 839
},
"largeTablet": {
"minWidth": 840
}
}
}
4.2 动态布局适配
// ResponsiveLayout.js - 响应式布局组件
import { BreakpointSystem } from '@ohos/breakpointsystem';
export default class ResponsiveLayout {
static breakpoints = {
phone: 0,
tablet: 600,
desktop: 1024
};
static getCurrentLayout(width) {
if (width >= this.breakpoints.desktop) {
return 'desktop';
} else if (width >= this.breakpoints.tablet) {
return 'tablet';
} else {
return 'phone';
}
}
static applyLayoutStrategy(component, width) {
const layoutType = this.getCurrentLayout(width);
// 上报布局切换事件
DeviceAnalytics.getInstance().reportLayoutChange(layoutType);
switch (layoutType) {
case 'desktop':
return this.applyDesktopLayout(component);
case 'tablet':
return this.applyTabletLayout(component);
default:
return this.applyPhoneLayout(component);
}
}
static trackLayoutPerformance(layoutType, loadTime) {
// 上报布局加载性能
DeviceAnalytics.getInstance().analytics.onEvent('layout_performance', {
layout_type: layoutType,
load_time: loadTime,
device_type: device.deviceType
});
}
}
五、用户行为分析
5.1 交互热力图采集
// HeatmapTracker.java - 交互热力图跟踪
import com.huawei.agconnect.analytics.AGConnectAnalytics;
import ohos.agp.components.Component;
import ohos.multimodalinput.event.TouchEvent;
public class HeatmapTracker {
public static void trackComponent(Component component) {
component.setTouchEventListener((component1, touchEvent) -> {
if (touchEvent.getAction() == TouchEvent.PRIMARY_POINT_DOWN) {
// 记录触摸位置
int[] location = new int[2];
component1.getLocationOnScreen(location);
JSONObject heatData = new JSONObject();
try {
heatData.put("x", location[0] + touchEvent.getPointerPosition(0).getX());
heatData.put("y", location[1] + touchEvent.getPointerPosition(0).getY());
heatData.put("component", component1.getId());
heatData.put("timestamp", System.currentTimeMillis());
} catch (JSONException e) {
e.printStackTrace();
}
// 上报热力数据
AGConnectAnalytics.getInstance(component1.getContext())
.onEvent("heatmap_data", heatData);
}
return false;
});
}
public static void trackScreen(String screenName) {
AGConnectAnalytics.getInstance().setCurrentScreen(
screenName,
screenName + "Screen"
);
}
}
5.2 功能使用率分析
// FeatureUsageAnalytics.ts - 功能使用分析
import DeviceAnalytics from './DeviceAnalytics';
export default class FeatureUsageAnalytics {
private static instance: FeatureUsageAnalytics;
private analytics: any;
private constructor() {
this.analytics = DeviceAnalytics.getInstance().analytics;
}
public static getInstance(): FeatureUsageAnalytics {
if (!FeatureUsageAnalytics.instance) {
FeatureUsageAnalytics.instance = new FeatureUsageAnalytics();
}
return FeatureUsageAnalytics.instance;
}
// 记录功能使用事件
public trackFeatureUsage(featureName: string, params?: object) {
const eventParams = {
feature: featureName,
device_type: device.deviceType,
screen_size: `${window.width}x${window.height}`,
...params
};
this.analytics.onEvent('feature_usage', eventParams);
}
// 记录功能耗时
public trackFeatureDuration(featureName: string, duration: number) {
this.analytics.onEvent('feature_duration', {
feature: featureName,
duration_ms: duration,
device_type: device.deviceType
});
}
// 记录功能异常
public trackFeatureError(featureName: string, error: Error) {
this.analytics.onEvent('feature_error', {
feature: featureName,
error_message: error.message,
stack_trace: error.stack,
device_type: device.deviceType
});
}
}
六、AGC数据分析看板
6.1 自定义分析指标配置
在AGC控制台创建自定义事件：
device_activation
screen_resize
layout_performance
feature_usage
设置用户属性：
device_profile
device_capabilities
创建设备分析看板：
// 示例看板配置
{
"widgets": [
{
"type": "pie",
"title": "设备类型分布",
"metric": "device_type",
"filter": "event=device_activation"
},
{
"type": "bar",
"title": "不同设备功能使用率",
"metrics": [
{
"name": "feature_usage",
"dimension": "feature",
"filter": "device_type=TV"
},
{
"name": "feature_usage",
"dimension": "feature",
"filter": "device_type=Tablet"
}
]
}
]
}
6.2 关键性能指标监控
// PerformanceMonitor.java - 性能监控
import com.huawei.agconnect.analytics.AGConnectAnalytics;
import ohos.app.Context;
public class PerformanceMonitor {
private long startTime;
private String screenName;
public PerformanceMonitor(Context context, String screenName) {
this.screenName = screenName;
this.startTime = System.currentTimeMillis();
// 记录屏幕访问
AGConnectAnalytics.getInstance(context)
.onEvent("screen_view", createScreenViewEvent());
}
public void reportScreenLoaded() {
long loadTime = System.currentTimeMillis() - startTime;
JSONObject metrics = new JSONObject();
try {
metrics.put("screen_name", screenName);
metrics.put("load_time", loadTime);
metrics.put("device_type", DeviceCapabilityDetector.getDeviceType());
} catch (JSONException e) {
e.printStackTrace();
}
AGConnectAnalytics.getInstance().onEvent("screen_performance", metrics);
}
public void reportComponentRender(String componentId, long renderTime) {
// 组件级性能监控
}
}
七、大屏优化策略
7.1 基于数据的布局优化
// LayoutOptimizer.js - 布局优化器
import FeatureUsageAnalytics from './FeatureUsageAnalytics';
export default class LayoutOptimizer {
static async optimizeLayout() {
// 从AGC获取分析数据（伪代码）
const analyticsData = await this.fetchLayoutAnalytics();
// 根据使用率调整布局优先级
if (analyticsData.tv?.feature_usage?.multi_window > 0.7) {
this.enableMultiWindowLayout();
}
// 根据错误率调整组件位置
if (analyticsData.tablet?.feature_errors?.navigation > 0.1) {
this.adjustNavigationPosition();
}
}
static async fetchLayoutAnalytics() {
// 实际项目中通过AGC API获取数据
return {
tv: {
feature_usage: {
multi_window: 0.82,
split_view: 0.65
},
feature_errors: {
navigation: 0.05
}
},
tablet: {
// ...其他设备数据
}
};
}
}
7.2 设备专属功能开关
// FeatureToggle.java - 功能开关
import com.huawei.agconnect.remoteconfig.AGConnectRemoteConfig;
import ohos.app.Context;
public class FeatureToggle {
private static final String FEATURE_MULTI_WINDOW = "multi_window_enabled";
private static final String FEATURE_SPLIT_VIEW = "split_view_enabled";
public static boolean isMultiWindowEnabled(Context context) {
return getConfigValue(context, FEATURE_MULTI_WINDOW,
DeviceCapabilityDetector.isLargeScreen(context));
}
public static boolean isSplitViewEnabled(Context context) {
return getConfigValue(context, FEATURE_SPLIT_VIEW,
DeviceCapabilityDetector.getDeviceType(context).equals("TV"));
}
private static boolean getConfigValue(Context context, String key, boolean defaultValue) {
return AGConnectRemoteConfig.getInstance(context)
.getValue(key)
.asBoolean(defaultValue);
}
}
八、完整示例：大屏视频播放器
// VideoPlayer.ts - 自适应视频播放器
import DeviceAnalytics from './DeviceAnalytics';
import FeatureUsageAnalytics from './FeatureUsageAnalytics';
import ResponsiveLayout from './ResponsiveLayout';
export default class VideoPlayer {
private player: any;
private currentLayout: string;
constructor(container: HTMLElement) {
this.initPlayer(container);
this.setupAnalytics();
this.setupResponsiveBehavior();
}
private initPlayer(container: HTMLElement) {
// 初始化播放器实例
this.player = new VideoPlayerCore(container);
// 上报播放器初始化事件
DeviceAnalytics.getInstance().reportDeviceInfo();
FeatureUsageAnalytics.getInstance()
.trackFeatureUsage('video_player_init');
}
private setupAnalytics() {
// 播放事件监听
this.player.on('play', () => {
FeatureUsageAnalytics.getInstance()
.trackFeatureUsage('video_play', {
video_id: this.player.currentVideo.id,
resolution: this.player.getResolution()
});
});
// 错误监听
this.player.on('error', (error) => {
FeatureUsageAnalytics.getInstance()
.trackFeatureError('video_playback', error);
});
}
private setupResponsiveBehavior() {
// 初始布局
this.currentLayout = ResponsiveLayout.getCurrentLayout(window.width);
this.applyLayout(this.currentLayout);
// 响应窗口大小变化
window.addEventListener('resize', () => {
const newLayout = ResponsiveLayout.getCurrentLayout(window.width);
if (newLayout !== this.currentLayout) {
this.currentLayout = newLayout;
this.applyLayout(newLayout);
// 上报布局变化
DeviceAnalytics.getInstance()
.reportScreenChange({
width: window.width,
height: window.height
});
}
});
}
private applyLayout(layoutType: string) {
const startTime = Date.now();
switch (layoutType) {
case 'desktop':
this.player.enableAdvancedControls(true);
this.player.setLayout('wide');
break;
case 'tablet':
this.player.enableAdvancedControls(true);
this.player.setLayout('normal');
break;
default: // phone
this.player.enableAdvancedControls(false);
this.player.setLayout('compact');
}
// 上报布局性能
ResponsiveLayout.trackLayoutPerformance(
layoutType,
Date.now() - startTime
);
}
}
九、常见问题解决
数据上报延迟：
// 手动立即上报
AGConnectAnalytics.getInstance(context)
.setAnalyticsEnabled(true)
.setSessionDuration(60000) // 60秒
.setUploadInterval(30000); // 30秒
大屏设备识别错误：
// 增强设备检测
function enhanceDeviceDetection() {
const isLargeScreen = window.width >= 600 ||
device.deviceType === 'TV' ||
device.deviceType === 'Tablet';
return {
...device,
isLargeScreen,
isTouchDevice: 'ontouchstart' in window
};
}
热力图数据过载：
// 采样率控制
public static boolean shouldSampleHeatmap() {
Random random = new Random();
return random.nextFloat() < 0.3; // 30%采样率
}
跨设备数据对比：
/* AGC分析查询示例 */
SELECT
device_type,
AVG(load_time) as avg_load_time
FROM
screen_performance
WHERE
screen_name = 'MainActivity'
GROUP BY
device_type
ORDER BY
avg_load_time DESC
