在 Android 10 上,当我收到推送通知时,振动仅在应用程序打开时有效。如果它在后台或关闭,振动不起作用(但通知通过并且声音起作用)。这是一个错误吗?但是在 Google 的错误跟踪器中找不到它。
我从我们的服务器发送带有数据负载的推送通知,这确保onMessageReceived()即使应用程序在后台也能被调用。确实如此,我可以调试它。
以下是通知渠道的创建方式:
NotificationChannel mChannelUp = new NotificationChannel(CHANNEL_ID_ALERTS_UP, getApplicationContext().getString(R.string.alerts_up), NotificationManager.IMPORTANCE_HIGH);
mChannelUp.enableLights(true);
mChannelUp.enableVibration(true);
// mChannelUp.setVibrationPattern(new long[]{500, 250, 500, 250}); // doesn't help
mChannelUp.setLightColor(Color.BLUE);
AudioAttributes audioAttributesUp = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION_EVENT)
.build();
mChannelUp.setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/" + R.raw.notif_sound_up), audioAttributesUp);
notificationManager.createNotificationChannel(mChannelUp);

和通知本身:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this, CHANNEL_ID_ALERTS_UP)
.setAutoCancel(true)
.setSmallIcon(R.drawable.ic_notif)
.setColor(ContextCompat.getColor(this, R.color.colorPrimary))
.setLargeIcon(logo)
.setVibrate(new long[]{250, 500, 250, 500})
.setLights(Color.parseColor("#039be5"), 500, 500)
.setContentTitle("some title")
.setContentText("some content")
.setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/" + R.raw.notif_sound_up));
mBuilder.setContentIntent(resultPendingIntent);
Notification notif = mBuilder.build();
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mNotifyMgr.notify(notificationId, notif);

我现在在 Logcat 中注意到了这一点:
忽略传入的振动,因为 uid = 10587 的进程是后台,usage = USAGE_NOTIFICATION_EVENT
要使振动即使在应用程序处于后台时也能工作,您需要使用AudioAttributes.USAGE_NOTIFICATION(USAGE_NOTIFICATION_EVENT不会工作!)并且还在setVibrationPattern频道上使用:
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build();
NotificationChannel mChannelUp = new NotificationChannel(CHANNEL_ID_ALERTS_UP, getApplicationContext().getString(R.string.alerts_up), NotificationManager.IMPORTANCE_HIGH);
mChannelUp.enableLights(true);
mChannelUp.enableVibration(true);
mChannelUp.setVibrationPattern(new long[]{0, 300, 250, 300, 250, 300});
mChannelUp.setLightColor(Color.BLUE);
mChannelUp.setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/" + R.raw.notif_sound_up), audioAttributes);
notificationManager.createNotificationChannel(mChannelUp);

现在,当应用程序在后台运行时,振动也可以工作。
感谢ijigarsolanki 的回答帮助我意识到了这一点。
