【问题描述】:
我正在使用 Android O 模拟器并希望从 Firebase 控制台获取通知。它在除 Android O 之外的所有设备上都可以正常工作。我在日志中收到此错误。
W/Notification: Use of stream types is deprecated for operations other than volume control
W/Notification: See the documentation of setSound() for what to use instead with android.media.AudioAttributes to qualify your playback use case
我知道我必须为此指定频道 ID。 所以到目前为止我做了什么
AndroidManifest.xml
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/attach" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/colorAccent" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="my_notification_channel" />
<service android:name=".Helper.FirebaseIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service android:name=".Helper.MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<my all activities...>
我还像这样在 FirebaseMessagingService 中指定了频道 ID
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
private static final int NOTIFICATION_ID = 1;
private static final String NOTIFICATION_CHANNEL_ID = "my_notification_channel";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_DEFAULT);
// Configure the notification channel.
notificationChannel.setDescription("Channel description");
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
notificationChannel.enableVibration(true);
notificationManager.createNotificationChannel(notificationChannel);
}
NotificationCompat.Builder mBuilder;
mBuilder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Title")
.setContentText(remoteMessage.getNotification().getBody())
.setOngoing(true)
.setChannelId(NOTIFICATION_CHANNEL_ID);
notificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
所以在做完这一切之后。我仍然在日志中收到该错误消息,并且无法从控制台接收通知。任何帮助都会很重要。
【问题讨论】:

投反对票有什么原因吗?
-
您是否看到
From:日志消息表明已收到消息? -
当应用程序在前台时,我可以看到。但是在应用程序进入后台后,它会显示错误。@BobSnyder
-
Firebase support for notification channels 是在 10.2.6 版中添加的。您正在使用该版本或更高版本进行构建吗?
-
@Tej 你能帮我解决同样的问题吗.....你是如何解决项目中的问题的?您在项目中的哪里创建了通知通道?
