Android 11 上未收到 RECEIVE_BOOT_COMPLETED

Question

我正在重新启动手机，希望看到一条日志消息。我已在

BroadcastReceiver

中注册了

Androidmanifest

，但没有收到任何消息。我错过了什么？

androidmanifest：

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


    <!-- Receives an event when the device has completed a reboot -->
    <receiver
        android:name=".BootReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <category android:name="android.intent.category.DEFAULT"/>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
            <action android:name="android.intent.action.BOOT" />
            <action android:name="android.intent.action.LOCKED_BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        </intent-filter>
    </receiver>

启动接收器：

class BootReceiver : BroadcastReceiver() {
    override fun onReceive(p0: Context, p1: Intent) {
        Log.i("BootReceiver", "Boot event received")
    }
}

当我过滤“启动”日志记录时，我看到其他几个应用程序正在记录该事件，但不是我自己的应用程序：

I/NU.LockBootCompleteReceiver: onReceive : Intent { act=android.intent.action.LOCKED_BOOT_COMPLETED flg=0x89000010 cmp=com.samsung.android.app.telephonyui/.netsettings.ui.receiver.LockBootCompleteReceiver (has extras) }

Answer 1

删除：

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

类别通常仅用于活动，而不用于广播。

Answer 2

Android3.1之后，为了加强安全控制，系统在应用程序安装后或在（设置）应用程序管理中强制关闭。该状态下，除非广播带有 FLAG_INCLUDE_STOPPED_PACKAGES 标志，否则无法接收到广播，并且默认情况下所有系统广播都是 FLAG_EXCLUDE_STOPPED_PACKAGES，所以无法通过系统广播自启动。

因此，安装应用程序后，必须先自行启动应用程序，使其不处于停止状态，才可以接收广播。

Answer 3

每次重新启动设备时我都能看到日志。 尝试更换您的设备并进行测试。

检查清单。
