android - 应用关闭时收到通知

Question

我使用 onesignal 向我的应用程序发送通知。当我发送通知并打开时，该应用程序运行良好。不幸的是，即使我设置了广播接收器，该应用程序在关闭时也没有收到通知。

<receiver
        android:name="com.onesignal.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="${applicationId}" />
        </intent-filter>
    </receiver>
 <receiver android:name="com.onesignal.BootUpReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        </intent-filter>
    </receiver>
<service android:name="com.onesignal.GcmIntentService" />
    <service
        android:name="com.onesignal.SyncService"
        android:stopWithTask="false" />

只需让接收器类扩展 WakefulBroadcastReceiver 并在您的 list 中添加以下行:

<receiver android:name=".YOUR_RECEIVER_CLASS"
       android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
    <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
    <action android:name="com.google.android.c2dm.intent.REGISTRATION"/> 
    <category android:name="com.example.gcm"/>
</intent-filter>
</receiver>
