重新启动后未收到Android启动完成通知 [英] Android boot completed notification not received after reboot

问题描述

我在应用程序清单中注册了一个广播接收器，以接收BOOT_COMPLETED通知.重新启动移动设备后，我没有收到任何通知.但是，当我打开我的应用程序时，确实会收到通知.请协助.

I have a broadcast receiver registered in the application manifest to receive the BOOT_COMPLETED notification. After restarting the mobile device I receive no notification. However, I do receive the notification when I open my application. Please assist.

从清单中接收启动完成的权限:

Receive boot completed permission from my manifest:

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

我的清单中的收件人:

    <receiver android:name=".BootCompletedReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

BootCompletedReceiver类:

BootCompletedReceiver class:

public class BootCompletedReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Toast.makeText(context, "Boot Completed Received", Toast.LENGTH_LONG).show();
    }

推荐答案

在线上有一些建议，除了BOOT_COMPLETED操作外，您还需要某些设备支持的QUICKBOOT_POWERON. 您可以查看问题/答案以了解详细信息.

There as some suggestions online that except the BOOT_COMPLETED action you also need the QUICKBOOT_POWERON that is supported by some devices. You can check this Q/A for details.

要实现此目的，我还必须添加android:enabled="false"，然后在用户选择时按需添加，我以编程方式将其更改为android:enabled="true"，但是尝试起来有点复杂.

Tring to implement this I also had to add the android:enabled="false" and then on demand when the user select it I programmatically changed this to android:enabled="true" but this a bit more complicated to try.

您可以首先通过更改代码来查看它是否有效.

You can start by changing your code with this to see if it works.

<receiver android:name=".BootCompletedReceiver" 
    android:enabled="true">
    <intent-filter>
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

如果您想尝试禁用逻辑，然后以编程方式启用此功能，请使用以下代码:

In case you like to try the disable logic and then enable this programmatically to do it use this code:

private static void changeBootStateReceiver(Context context, boolean enable) {
    ComponentName receiver = new ComponentName(context, BootCompletedReceiver.class);
    PackageManager pm = context.getPackageManager();

    pm.setComponentEnabledSetting(receiver,
            enable ? PackageManager.COMPONENT_ENABLED_STATE_ENABLED
                    : PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
            PackageManager.DONT_KILL_APP);
}

我也想在不再需要该功能时将其禁用.

I also like to disable the feature when I no longer need it.

特殊情况:

根据设备制造商的不同，在启动时会有一些有关不同广播的报告:

Depending on device manufacturer there are some reports for different broadcasts upon boot:

• Xiaomi MIUI 使用:android.intent.action.REBOOT
• HTC 使用:com.htc.action.QUICKBOOT_POWERON

• Xiaomi MIUI use: android.intent.action.REBOOT
• HTC use: com.htc.action.QUICKBOOT_POWERON
