startForeground fails with Bad notification for startForeground

android.app.RemoteServiceException: Bad notification for startForeground

@Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        String message = intent.getStringExtra("message");
        int id = intent.getIntExtra("ID", 1);

        Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);

        Intent firstActivityIntent = new Intent(this, FirstActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        stackBuilder.addParentStack(FirstActivity.class);
        stackBuilder.addNextIntent(firstActivityIntent);

        Intent notificationUpdateIntent = new Intent(this, UpdateNotificationActivity.class);
        notificationUpdateIntent.putExtra("ID", id);
        stackBuilder.addNextIntent(notificationUpdateIntent);


        PendingIntent pendingIntent = stackBuilder.getPendingIntent(id, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification notification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
                .setContentTitle("Reminder")
                .setContentText(message)
                .setSmallIcon(R.drawable.noteappicon)
                .setStyle(new NotificationCompat.BigTextStyle())
                .setAutoCancel(true)
                .setContentIntent(pendingIntent)
                .build();

        startForeground(1, notification);

我在 Android 11 中遇到的错误

at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2005)
        at android.os.Handler.dispatchMessage(Handler.java:106)
        at android.os.Looper.loop(Looper.java:223)

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:947)

这是10中的错误

android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=channel1 pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x50 color=0x00000000 vis=PRIVATE)

android.app.RemoteServiceException：startForeground 的错误通知已添加到帖子
好吧抱歉
这就是我在日志中的全部内容

【解决方案1】：

我的频道 ID 错误需要创建一些频道 ID，就像我过去的问题一样

我为 Channel id 创建了另一个类

如果 (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { NotificationChannel 通道 1 = 新 NotificationChannel( CHANNEL_1_ID， "频道 1", NotificationManager.IMPORTANCE_HIGH ); channel1.setDescription("这是频道 1");

    NotificationChannel channel2 = new NotificationChannel(
            CHANNEL_2_ID,
            "Channel 2",
            NotificationManager.IMPORTANCE_LOW
    );
    channel2.setDescription("This is channel 2");

    NotificationManager manager = getSystemService(NotificationManager.class);
    manager.createNotificationChannel(channel1);
    manager.createNotificationChannel(channel2);
}

}

【解决方案2】：

        PendingIntent pendingIntent = PendingIntent.GetActivity(context , startId ,intent, PendingIntentFlags.UpdateCurrent);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(AndroidApp.Context, channelId)
           .SetContentIntent(pendingIntent)
           .SetContentTitle(title)
           .SetContentText(Message)
           .SetLargeIcon(BitmapFactory.DecodeResource(AndroidApp.Context.Resources, Resource.Drawable.common_google_signin_btn_icon_dark_normal))
           .SetSmallIcon(Resource.Drawable.common_google_signin_btn_icon_dark_normal)
           .SetDefaults((int)NotificationDefaults.Sound | (int)NotificationDefaults.Vibrate);

        Notification notification = builder.Build();
