Android 15下ACTION_BOOT_COMPLETED失效，如何可靠检测真实开机？

背景 #

在Android 14及之前版本中，使用ACTION_BOOT_COMPLETED可正常检测系统开机并执行相关操作，示例实现如下：

BootReceiver.kt #

class BootReceiver : BroadcastReceiver() {

    @SuppressLint("UnsafeProtectedBroadcastReceiver")
    @UiThread
    override fun onReceive(context: Context, intent: Intent) {
             ...

清单文件配置 #

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

...

<receiver
    android:name=".receivers.BootReceiver" android:enabled="false" android:exported="false">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

问题 #

在Android 15中，该Intent会在多种非开机场景下触发，例如Android Studio调试、强制停止应用后从应用信息页启动等。

已尝试方案 #

计划使用API 34（Android 14及以上支持）的addApplicationStartInfoCompletionListener，通过ApplicationStartInfo.getReason()判断启动原因，若返回值为START_REASON_BOOT_COMPLETE则判定为真实开机，示例代码如下：

inline fun <reified T : Any> Context.getSystemServiceCompat(): T =
        ContextCompat.getSystemService(applicationContext, T::class.java)!!

...

val activityManager: ActivityManager = context.getSystemServiceCompat()
activityManager.addApplicationStartInfoCompletionListener(ExecutorEx.diskIO) { applicationStartInfo ->
            val reasonStr = when (val reason = applicationStartInfo.reason) {
                ApplicationStartInfo.START_REASON_ALARM -> "START_REASON_ALARM"
                ApplicationStartInfo.START_REASON_BACKUP -> "START_REASON_BACKUP"
                ApplicationStartInfo.START_REASON_BOOT_COMPLETE -> "START_REASON_BOOT_COMPLETE"
                ApplicationStartInfo.START_REASON_BROADCAST -> "START_REASON_BROADCAST"
                ApplicationStartInfo.START_REASON_CONTENT_PROVIDER -> "START_REASON_CONTENT_PROVIDER"
                ApplicationStartInfo.START_REASON_JOB -> "START_REASON_JOB"
                ApplicationStartInfo.START_REASON_LAUNCHER -> "START_REASON_LAUNCHER"
                ApplicationStartInfo.START_REASON_LAUNCHER_RECENTS -> "START_REASON_LAUNCHER_RECENTS"
                ApplicationStartInfo.START_REASON_OTHER -> "START_REASON_OTHER"
                ApplicationStartInfo.START_REASON_PUSH -> "START_REASON_PUSH"
                ApplicationStartInfo.START_REASON_SERVICE -> "START_REASON_SERVICE"
                ApplicationStartInfo.START_REASON_START_ACTIVITY -> "START_REASON_START_ACTIVITY"
                else -> {
                    logException("unknown applicationStartInfo reason:$reason")
                    "Unknown:$reason"
                }
            }
            Log.d("AppLog", "reasonStr:$reasonStr")

但实际开机时返回的是START_REASON_BROADCAST，且该方法为回调形式，无法直接在BootReceiver的onReceive方法中使用。

同时发现真实开机与非开机场景（假开机）的Intent Flag不同：

• 非开机场景（仅启动应用）：Flag为0x9000030
• 真实开机：Flag为0x89000010

疑问 #

1. 在Android 15中，是否存在可靠方法可在已创建的BootReceiver类中检测真实开机？
2. 通过检测Intent Flag的方式是否属于可靠的检测方案？
