在Android上,推送通知音丢失的问题可能涉及到应用在后台时无法播放声音的限制。为了解决这个问题,可以尝试以下方法:
...
// 在应用启动的时候创建通知通道
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("channel_id", "Channel Name", NotificationManager.IMPORTANCE_HIGH);
channel.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION), new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build());
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
// 创建通知的构建器
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Notification Title")
.setContentText("Notification Content")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setAutoCancel(true);
// 发送通知
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, builder.build());
通过以上步骤,应用在Android上收到推送通知时应该能够正常播放声音。请注意,具体的实现方式可能会根据你使用的推送服务(如Firebase Cloud Messaging)和通知库(如NotificationCompat)而有所不同。
