# DeviceInfo - Device ID 和 GAID 使用示例
## 概述
DeviceInfo 类现在提供了完整的设备标识符获取功能,包括 Android ID (Device ID) 和 Google Advertising ID (GAID)。
## 新增功能
### 1. Android ID (Device ID)
- `getAndroidId()` - 获取 Android ID
### 2. Google Advertising ID (GAID)
- `getAdvertisingId()` - 协程方式获取 GAID推荐
- `getAdvertisingIdSync()` - 同步方式获取 GAID不推荐
- `getDeviceIdentifiers()` - 获取所有标识符
### 3. 数据类
- `AdvertisingIdInfo` - GAID 信息
- `DeviceIdentifiers` - 设备标识符集合
## 使用方法
### 1. 初始化
```kotlin
import com.xyzshell.andinfo.AndInfo
// 在 Application 或 Activity 中初始化
AndInfo.init(applicationContext)
// 获取 DeviceInfo 实例
val deviceInfo = AndInfo.instance.device
```
### 2. 获取 Android ID (Device ID)
#### 基本使用
```kotlin
// 获取 Android ID
val androidId = deviceInfo.getAndroidId()
println("Android ID: $androidId")
// 输出示例: "Android ID: 9774d56d682e549c"
```
#### Android ID 特点
- **格式**: 64位十六进制字符串
- **生成时机**: 设备首次启动时随机生成
- **持久性**:
- 出厂重置后会改变
- 清除应用数据不会改变
- **作用域**:
- Android 8.0+ 后,每个应用和用户组合都会获得不同的 Android ID
- Android 8.0 之前,所有应用获得相同的 Android ID
- **权限**: 不需要特殊权限
#### 适用场景
```kotlin
// 1. 应用级设备标识
fun getDeviceTag(): String {
val deviceInfo = AndInfo.instance.device
return "device_${deviceInfo.getAndroidId()}"
}
// 2. 用户设备绑定
fun bindDeviceToUser(userId: String) {
val deviceInfo = AndInfo.instance.device
val androidId = deviceInfo.getAndroidId()
// 将 androidId 与 userId 关联存储
saveBinding(userId, androidId)
}
// 3. 设备唯一性校验
fun isNewDevice(): Boolean {
val deviceInfo = AndInfo.instance.device
val androidId = deviceInfo.getAndroidId()
return !isDeviceRegistered(androidId)
}
```
### 3. 获取 GAID (Google Advertising ID)
#### 协程方式(推荐)
```kotlin
import androidx.lifecycle.lifecycleScope
import kotlinx.coroutines.launch
// 在 Activity 或 Fragment 中
lifecycleScope.launch {
val deviceInfo = AndInfo.instance.device
val gaidInfo = deviceInfo.getAdvertisingId()
if (gaidInfo != null) {
println("GAID: ${gaidInfo.id}")
println("是否限制追踪: ${gaidInfo.isLimitAdTrackingEnabled}")
// 根据追踪限制状态决定是否使用
if (!gaidInfo.isLimitAdTrackingEnabled) {
// 用户允许广告追踪,可以使用 GAID
sendToAnalytics(gaidInfo.id)
} else {
// 用户限制了广告追踪,应该尊重用户选择
println("用户已限制广告追踪")
}
} else {
// Google Play Services 不可用
println("无法获取 GAID设备可能没有 Google Play Services")
}
}
```
#### 在 ViewModel 中使用
```kotlin
class MainViewModel : ViewModel() {
fun loadAdvertisingId() {
viewModelScope.launch {
val deviceInfo = AndInfo.instance.device
val gaidInfo = deviceInfo.getAdvertisingId()
gaidInfo?.let { info ->
_advertisingId.value = info.id
_isTrackingLimited.value = info.isLimitAdTrackingEnabled
}
}
}
}
```
#### 同步方式(不推荐)
```kotlin
// ⚠️ 警告:会阻塞当前线程,不要在主线程调用
Thread {
val deviceInfo = AndInfo.instance.device
val gaidInfo = deviceInfo.getAdvertisingIdSync()
gaidInfo?.let { info ->
println("GAID: ${info.id}")
}
}.start()
```
#### GAID 特点
- **格式**: UUID 格式的字符串
- **示例**: "38400000-8cf0-11bd-b23e-10b96e40000d"
- **依赖**: 需要 Google Play Services
- **用户控制**:
- 用户可以在设置中重置 GAID
- 用户可以选择限制广告追踪
- **权限**: 不需要特殊权限,但需要 Google Play Services
- **线程**: 必须在后台线程调用
### 4. 获取所有设备标识符
```kotlin
// 一次性获取所有标识符
lifecycleScope.launch {
val deviceInfo = AndInfo.instance.device
val identifiers = deviceInfo.getDeviceIdentifiers()
println("=== 设备标识符 ===")
println("Android ID: ${identifiers.androidId}")
identifiers.advertisingId?.let { gaid ->
println("GAID: ${gaid.id}")
println("限制追踪: ${gaid.isLimitAdTrackingEnabled}")
} ?: run {
println("GAID: 不可用")
}
}
```
### 5. 完整示例:设备信息收集
```kotlin
class DeviceInfoActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
lifecycleScope.launch {
collectDeviceInfo()
}
}
private suspend fun collectDeviceInfo() {
val deviceInfo = AndInfo.instance.device
// 基本设备信息
val brand = deviceInfo.brand
val model = deviceInfo.model
val manufacturer = deviceInfo.manufacturer
// 设备标识符
val androidId = deviceInfo.getAndroidId()
val gaidInfo = deviceInfo.getAdvertisingId()
// 显示信息
val info = buildString {
appendLine("=== 设备信息 ===")
appendLine("品牌: $brand")
appendLine("型号: $model")
appendLine("制造商: $manufacturer")
appendLine()
appendLine("=== 设备标识符 ===")
appendLine("Android ID: $androidId")
if (gaidInfo != null) {
appendLine("GAID: ${gaidInfo.id}")
appendLine("限制追踪: ${if (gaidInfo.isLimitAdTrackingEnabled) "是" else "否"}")
} else {
appendLine("GAID: 不可用(可能没有 Google Play Services")
}
}
println(info)
// 或显示在 UI 上
// textView.text = info
}
}
```
## 数据结构
### AdvertisingIdInfo
```kotlin
/**
* 广告标识符信息数据类
*/
data class AdvertisingIdInfo(
val id: String, // GAID
val isLimitAdTrackingEnabled: Boolean // 是否限制广告追踪
)
```
### DeviceIdentifiers
```kotlin
/**
* 设备标识符集合数据类
*/
data class DeviceIdentifiers(
val androidId: String, // Android ID
val advertisingId: AdvertisingIdInfo? // GAID可能为 null
)
```
## Android ID vs GAID 对比
| 特性 | Android ID | GAID |
|------|-----------|------|
| **格式** | 64位十六进制 | UUID |
| **示例** | 9774d56d682e549c | 38400000-8cf0-11bd-b23e-10b96e40000d |
| **依赖** | 无 | Google Play Services |
| **权限** | 无需权限 | 无需权限 |
| **重置** | 出厂重置后改变 | 用户可随时重置 |
| **作用域** | Android 8.0+ 按应用区分 | 全局统一 |
| **用户控制** | 不可控制 | 可限制追踪 |
| **适用场景** | 应用内标识、设备绑定 | 广告追踪、分析 |
| **隐私友好** | 中等 | 高(用户可控) |
## 典型应用场景
### 1. 广告归因
```kotlin
suspend fun trackAdConversion(campaignId: String) {
val deviceInfo = AndInfo.instance.device
val gaidInfo = deviceInfo.getAdvertisingId()
if (gaidInfo != null && !gaidInfo.isLimitAdTrackingEnabled) {
// 用户允许追踪,上报转化数据
analyticsService.trackConversion(
gaid = gaidInfo.id,
campaignId = campaignId
)
} else {
// 使用匿名方式或不追踪
analyticsService.trackAnonymousConversion(campaignId)
}
}
```
### 2. 用户设备管理
```kotlin
suspend fun registerDevice() {
val deviceInfo = AndInfo.instance.device
val identifiers = deviceInfo.getDeviceIdentifiers()
// 注册设备信息
val deviceProfile = DeviceProfile(
androidId = identifiers.androidId,
brand = deviceInfo.brand,
model = deviceInfo.model,
timestamp = System.currentTimeMillis()
)
saveDeviceProfile(deviceProfile)
}
```
### 3. 防作弊检测
```kotlin
suspend fun checkDeviceFraud(): Boolean {
val deviceInfo = AndInfo.instance.device
val androidId = deviceInfo.getAndroidId()
// 检查设备是否被标记为作弊
return fraudDetectionService.isDeviceFlagged(androidId)
}
```
### 4. A/B 测试分组
```kotlin
suspend fun getExperimentGroup(): String {
val deviceInfo = AndInfo.instance.device
val gaidInfo = deviceInfo.getAdvertisingId()
// 使用 GAID 的哈希值进行分组
val deviceId = gaidInfo?.id ?: deviceInfo.getAndroidId()
val hash = deviceId.hashCode()
return if (hash % 2 == 0) "GroupA" else "GroupB"
}
```
### 5. 隐私合规检查
```kotlin
suspend fun checkPrivacyCompliance(): PrivacyStatus {
val deviceInfo = AndInfo.instance.device
val gaidInfo = deviceInfo.getAdvertisingId()
return PrivacyStatus(
hasGooglePlayServices = gaidInfo != null,
isTrackingLimited = gaidInfo?.isLimitAdTrackingEnabled ?: true,
canUsePersonalizedAds = gaidInfo?.let { !it.isLimitAdTrackingEnabled } ?: false
)
}
```
## 依赖配置
要使用 GAID 功能,需要在 `build.gradle` 中添加依赖:
```gradle
dependencies {
// Google Play Services - Advertising ID
implementation 'com.google.android.gms:play-services-ads-identifier:18.0.1'
// Kotlin Coroutines如果项目中还没有
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.7.3'
}
```
## 注意事项
### 1. Android ID
- ⚠️ Android 8.0+ 后,每个应用获得的 Android ID 不同
- ⚠️ 出厂重置后会改变
- ⚠️ 不应用于跨应用追踪
- ✅ 适合应用内设备标识
### 2. GAID
- ⚠️ 需要 Google Play Services国内设备可能不可用
- ⚠️ 必须尊重用户的"限制广告追踪"设置
- ⚠️ 必须在后台线程调用
- ⚠️ 用户可以随时重置
- ✅ 适合广告归因和分析
- ✅ 符合 Google Play 政策
### 3. 隐私合规
- 📋 遵守 GDPR、CCPA 等隐私法规
- 📋 在隐私政策中说明标识符用途
- 📋 尊重用户的追踪限制选择
- 📋 提供用户删除数据的选项
### 4. 最佳实践
```kotlin
suspend fun getDeviceIdentifierForAnalytics(): String? {
val deviceInfo = AndInfo.instance.device
// 1. 优先使用 GAID如果可用且用户允许
val gaidInfo = deviceInfo.getAdvertisingId()
if (gaidInfo != null && !gaidInfo.isLimitAdTrackingEnabled) {
return gaidInfo.id
}
// 2. 用户限制了追踪,不应该使用任何标识符
if (gaidInfo?.isLimitAdTrackingEnabled == true) {
return null // 返回 null 表示不追踪
}
// 3. GAID 不可用(可能是国内设备),使用 Android ID
// 注意:这种情况下应该获得用户明确同意
return if (hasUserConsent()) {
deviceInfo.getAndroidId()
} else {
null
}
}
```
## 示例输出

println("提示:系统无法直接读取内存类型,基于设备信息估算")
}

}
```
### 4. 内存性能评估
```kotlin
val memoryInfo = memInfo.getMemoryInfo()
// 评估内存性能等级
val performanceLevel = when {
memoryInfo.memType.contains("LPDDR5X") -> "旗舰级"
memoryInfo.memType.contains("LPDDR5") -> "高端"
memoryInfo.memType.contains("LPDDR4X") -> "中高端"
memoryInfo.memType.contains("LPDDR4") -> "中端"
else -> "入门"
}
println("内存性能等级: $performanceLevel")
println("理论带宽估算:")
when {
memoryInfo.memType.contains("LPDDR5X") -> {
val bandwidth = 8533 * memoryInfo.channels // LPDDR5X-8533
println(" 约 ${bandwidth} MB/s (${memoryInfo.channels}通道)")
}
memoryInfo.memType.contains("LPDDR5") -> {
val bandwidth = 6400 * memoryInfo.channels // LPDDR5-6400
println(" 约 ${bandwidth} MB/s (${memoryInfo.channels}通道)")
}
memoryInfo.memType.contains("LPDDR4X") -> {
val bandwidth = 4266 * memoryInfo.channels // LPDDR4X-4266
println(" 约 ${bandwidth} MB/s (${memoryInfo.channels}通道)")
}
}
```
### 5. 内存使用情况分析
```kotlin
val memoryInfo = memInfo.getMemoryInfo()
// 计算使用率
val usagePercentage = (memoryInfo.usedRam.toDouble() / memoryInfo.totalRam * 100).toInt()
println("=== 内存使用情况 ===")
println("总内存: ${memInfo.formatBytes(memoryInfo.totalRam)}")
println("已使用: ${memInfo.formatBytes(memoryInfo.usedRam)} (${usagePercentage}%)")
println("可用: ${memInfo.formatBytes(memoryInfo.availableRam)}")
// 使用状态
when {
usagePercentage >= 90 -> println("⚠️ 内存严重不足")
usagePercentage >= 75 -> println("⚠️ 内存偏紧")
usagePercentage >= 50 -> println("✓ 内存使用正常")
else -> println("✓ 内存充裕")
}
// ZRAM 情况
if (memoryInfo.zramTotal > 0) {
val zramUsagePercent = (memoryInfo.zramUsed.toDouble() / memoryInfo.zramTotal * 100).toInt()
println("\n=== ZRAM (压缩内存) ===")
println("ZRAM 大小: ${memInfo.formatBytes(memoryInfo.zramTotal)}")
println("ZRAM 已使用: ${memInfo.formatBytes(memoryInfo.zramUsed)} (${zramUsagePercent}%)")
}
```
### 6. 完整示例
```kotlin
class MemoryInfoActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
displayMemoryInfo()
}
private fun displayMemoryInfo() {
val memInfo = AndInfo.instance.mem
val memoryInfo = memInfo.getMemoryInfo()
val info = buildString {
appendLine("╔════════════════════════════════╗")
appendLine("║ 设备内存信息报告 ║")
appendLine("╚════════════════════════════════╝")
appendLine()
// 内存容量
appendLine("【内存容量】")
appendLine(" 总内存:${memInfo.formatBytes(memoryInfo.totalRam)}")
appendLine(" 可用:${memInfo.formatBytes(memoryInfo.availableRam)}")
appendLine(" 已使用:${memInfo.formatBytes(memoryInfo.usedRam)}")
val usagePercent = (memoryInfo.usedRam.toDouble() / memoryInfo.totalRam * 100).toInt()
appendLine(" 使用率:${usagePercent}%")
appendLine()
// 内存类型
appendLine("【内存规格】")
appendLine(" 类型:${memoryInfo.memType}")
appendLine(" 通道:${memoryInfo.channels} 通道")
// 性能评级
val perfLevel = when {

memoryInfo.memType.contains("LPDDR5") -> "⭐⭐⭐⭐ 高端"
memoryInfo.memType.contains("LPDDR4X") -> "⭐⭐⭐ 中高端"
memoryInfo.memType.contains("LPDDR4") -> "⭐⭐ 中端"
else -> "⭐ 入门"
}
appendLine(" 性能等级:$perfLevel")
appendLine()
// ZRAM 信息
if (memoryInfo.zramTotal > 0) {
appendLine("【ZRAM 压缩内存】")
appendLine(" 总大小:${memInfo.formatBytes(memoryInfo.zramTotal)}")
appendLine(" 已使用:${memInfo.formatBytes(memoryInfo.zramUsed)}")
val zramPercent = (memoryInfo.zramUsed.toDouble() / memoryInfo.zramTotal * 100).toInt()
appendLine(" 使用率:${zramPercent}%")
}
}
println(info)
// 或者显示在 TextView 中
// textView.text = info
}
}
```
## 检测原理说明
### 1. 系统属性检测
```kotlin
// 尝试读取系统属性
getprop ro.boot.ddr_type
// 可能返回: "LPDDR5", "4", "5" 等
```
### 2. Sysfs 文件检测
```kotlin
// Qualcomm 设备
/sys/class/devfreq/soc:qcom,cpu-cpu-llcc-bw/device/type
// MediaTek 设备
/sys/kernel/debug/emi_mbw/dram_type
// Samsung Exynos 设备
/sys/class/devfreq/17000010.devfreq_mif/device/type
```
### 3. 设备树检测
```kotlin
// 设备树路径
/proc/device-tree/memory/ddr-type
/sys/firmware/devicetree/base/memory/ddr-type
```
### 4. 内核日志检测
```bash
# 搜索内核日志
dmesg | grep -iE 'ddr|lpddr|memory.*type'
# 可能输出: "LPDDR5 detected", "DDR Type: 5" 等
```
### 5. 智能推测规则
| Android 版本 | 发布年份 | 估算类型 |
|-------------|---------|---------|
| 14+ | 2023+ | LPDDR5X |
| 13 | 2022-2023 | LPDDR5 |
| 12 | 2021-2022 | LPDDR5 |
| 11 | 2020-2021 | LPDDR4X |
| 10 | 2019-2020 | LPDDR4X |
| 9 | 2018-2019 | LPDDR4 |
| ≤8 | ≤2017 | LPDDR3 |
## 典型设备示例

```
## 注意事项
1. **权限要求**
- 无需特殊权限
- 某些检测路径可能需要 root 权限才能访问
2. **检测准确性**
- 优先级:系统属性 > Sysfs > 设备树 > 内核日志 > 估算
- 带 "(estimated)" 标记表示是推测值
3. **设备差异**
- 不同厂商的设备,内存信息存储位置可能不同
- 某些定制 ROM 可能修改了相关路径
4. **性能差异**
- 相同类型的内存,不同频率性能也不同
- 通道数会显著影响实际带宽
## 完成度

# 设备信息收集和上传使用指南
## 概述
本功能提供了完整的设备信息收集、序列化、加密和上传功能。所有信息收集都是异步并发执行,性能优化且不会阻塞主线程。
## 功能特性
### 1. 信息收集模块
自动收集以下 24 类设备信息:
- CPU 信息
- GPU 信息
- 屏幕信息
- 内存信息
- 磁盘信息
- 网络信息
- 电池信息
- 设备信息
- 应用信息
- 系统信息
- 定位信息
- 相机信息
- 传感器信息
- 系统属性
- 蓝牙信息
- WiFi 信息
- NFC 信息
- USB 信息
- 构建信息
- DRM 信息
- 输入设备信息
- Device ID
- GAID
### 2. 数据处理流程
1. **异步收集** - 并发收集所有信息,提高性能
2. **JSON 序列化** - 将所有信息转换为 JSON 格式
3. **AES 加密** - 使用 AES 加密保护数据
4. **HTTP POST** - 发送加密数据到服务器
5. **响应处理** - 解析服务器响应
## 使用方法
### 1. 基本使用
```kotlin
import androidx.lifecycle.lifecycleScope
import com.xyzshell.andinfo.AndInfo
import com.xyzshell.andinfo.collector.DeviceInfoCollector
import kotlinx.coroutines.launch
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// 初始化 AndInfo
AndInfo.init(applicationContext)
// 收集并上传设备信息
uploadDeviceInfo()
}
private fun uploadDeviceInfo() {
lifecycleScope.launch {
val collector = DeviceInfoCollector(applicationContext)
collector.collectAndUpload { message, error ->
if (error != null) {
// 上传失败
runOnUiThread {
Toast.makeText(
this@MainActivity,
"上传失败: ${error.message}",
Toast.LENGTH_LONG
).show()
}
} else {
// 上传成功
runOnUiThread {
Toast.makeText(
this@MainActivity,
"上传成功: $message",
Toast.LENGTH_SHORT
).show()
}
}
}
}
}
}
```
### 2. 仅收集信息(不上传)
```kotlin
lifecycleScope.launch {
val collector = DeviceInfoCollector(applicationContext)
// 仅收集信息,不上传
val deviceInfo = collector.collectAllInfo()
// 转换为 JSON 查看
val json = collector.gson.toJson(deviceInfo)
println("设备信息: $json")
}
```
### 3. 在 ViewModel 中使用
```kotlin
class DeviceInfoViewModel : ViewModel() {
private val _uploadStatus = MutableLiveData<UploadStatus>()
val uploadStatus: LiveData<UploadStatus> = _uploadStatus
fun uploadDeviceInfo(context: Context) {
viewModelScope.launch {
_uploadStatus.value = UploadStatus.Loading
val collector = DeviceInfoCollector(context)
collector.collectAndUpload { message, error ->
if (error != null) {
_uploadStatus.postValue(UploadStatus.Error(error.message ?: "上传失败"))
} else {
_uploadStatus.postValue(UploadStatus.Success(message ?: "上传成功"))
}
}
}
}
}
sealed class UploadStatus {
object Loading : UploadStatus()
data class Success(val message: String) : UploadStatus()
data class Error(val message: String) : UploadStatus()
}
```
### 4. 带进度显示的上传
```kotlin
class UploadActivity : AppCompatActivity() {
private lateinit var progressDialog: ProgressDialog
private fun uploadWithProgress() {
// 显示进度对话框
progressDialog = ProgressDialog(this).apply {
setMessage("正在收集设备信息...")
setCancelable(false)
show()
}
lifecycleScope.launch {
val collector = DeviceInfoCollector(applicationContext)
// 更新进度
progressDialog.setMessage("正在上传...")
collector.collectAndUpload { message, error ->
runOnUiThread {
progressDialog.dismiss()
if (error != null) {
AlertDialog.Builder(this@UploadActivity)
.setTitle("上传失败")
.setMessage(error.message)
.setPositiveButton("确定", null)
.show()
} else {
AlertDialog.Builder(this@UploadActivity)
.setTitle("上传成功")
.setMessage(message)
.setPositiveButton("确定", null)
.show()
}
}
}
}
}
}
```
### 5. 定时自动上传
```kotlin
class AutoUploadService : Service() {
private val uploadInterval = 24 * 60 * 60 * 1000L // 24小时
private val handler = Handler(Looper.getMainLooper())
private val uploadRunnable = object : Runnable {
override fun run() {
uploadDeviceInfo()
handler.postDelayed(this, uploadInterval)
}
}
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
handler.post(uploadRunnable)
return START_STICKY
}
private fun uploadDeviceInfo() {
CoroutineScope(Dispatchers.IO).launch {
val collector = DeviceInfoCollector(applicationContext)
collector.collectAndUpload { message, error ->
if (error != null) {
Log.e("AutoUpload", "上传失败: ${error.message}")
} else {
Log.i("AutoUpload", "上传成功: $message")
}
}
}
}
override fun onDestroy() {
handler.removeCallbacks(uploadRunnable)
super.onDestroy()
}
override fun onBind(intent: Intent?): IBinder? = null
}
```

val message: String, // 响应消息
val status: String // 状态: "Success" 或 "Fail"
)
```
## 加密说明
### AES 加密
- **算法**: AES/ECB/PKCS5Padding
- **密钥**: "e67cbcee5e573d1b" (16字节)
- **编码**: Base64 (NO_WRAP)
### 加密示例
```kotlin
val webService = WebService()
val plainText = """{"test": "data"}"""
val encrypted = webService.encrypt(plainText)
println("加密结果: $encrypted")
```
## 权限要求
根据收集的信息类型,可能需要以下权限:
```xml
<!-- 必需权限 -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- 可选权限(用于获取更多信息) -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
```
## 性能优化
### 1. 并发收集
所有信息收集都是并发执行:
```kotlin
// 使用协程并发收集
val cpuInfoDeferred = async { collectCpuInfo() }
val gpuInfoDeferred = async { collectGpuInfo() }
// ... 其他信息并发收集
```
### 2. 异常处理
每个收集方法都有完善的异常处理:
```kotlin
private suspend fun collectCpuInfo(): String = withContext(Dispatchers.Default) {
try {
// 收集逻辑
} catch (e: Exception) {
"{}" // 返回空JSON对象
}
}
```
### 3. 线程调度
- 信息收集:使用 `Dispatchers.Default``Dispatchers.IO`
- 加密操作:使用 `Dispatchers.Default`
- 网络请求:使用 `Dispatchers.IO`
## 错误处理
### 常见错误及解决方案
1. **网络错误**
```kotlin
// 错误: java.net.UnknownHostException
// 解决: 检查网络连接和URL是否正确
```
2. **加密错误**
```kotlin
// 错误: 加密失败
// 解决: 检查密钥长度是否为16/24/32字节
```
3. **序列化错误**
```kotlin
// 错误: JSON解析失败
// 解决: 确保所有收集方法返回有效的JSON字符串
```
## 注意事项
1. **隐私合规**
- 确保用户知情并同意收集设备信息
- 遵守 GDPR、CCPA 等隐私法规
- 在隐私政策中说明数据用途
2. **网络使用**
- 建议在 WiFi 环境下上传
- 可以添加网络类型检测
3. **频率控制**
- 不要频繁上传
- 建议每天或每周上传一次
4. **错误重试**
- 失败时可以实现重试机制
- 保存失败的数据,下次再试
## 完整示例
```kotlin
class DeviceCheckActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_device_check)
// 初始化
AndInfo.init(applicationContext)
// 检查权限后上传
if (checkPermissions()) {
uploadDeviceInfo()
} else {
requestPermissions()
}
}
private fun uploadDeviceInfo() {
lifecycleScope.launch {
try {
val collector = DeviceInfoCollector(applicationContext)
// 显示加载对话框
val dialog = ProgressDialog(this@DeviceCheckActivity)
