通知未在三星奥利奥设备中显示
Notification not showing in samsung oreo devices
我今天遇到了一个奇怪的问题,推送通知在装有 oreo 的三星设备上没有显示,但在其他 oreo 设备上工作正常。这是我正在使用的代码:
private void sendNotification(String messageTitle,String messageBody) {
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder notificationBuilder=null;
try {
Intent intent = new Intent(this, SplashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
String NOTIFICATION_CHANNEL="NB Shop Notification";
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.icon)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.icon))
.setSound(defaultSoundUri)
.setChannelId(NOTIFICATION_CHANNEL)
.setContentIntent(pendingIntent);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
/* Create or update. */
NotificationChannel channel;
channel=new NotificationChannel(NOTIFICATION_CHANNEL,
NOTIFICATION_CHANNEL,
NotificationManager.IMPORTANCE_DEFAULT);
if (notificationManager != null) {
notificationManager.createNotificationChannel(channel);
}
}
notificationManager.notify((int) System.currentTimeMillis(), notificationBuilder.build());
}catch (Exception e)
{
Log.d("sendNotification",e.toString());
}
}
它没有在日志中显示任何错误。
我发现了导致问题的原因,NotificationCompat.Builder 的构造函数 (NotificationCompat.Builder(this)
) 只有一个参数已被弃用,
为了摆脱弃用,我们必须使用构造函数发送通道 ID,所以我更改了代码并将通道 ID 传递给构造函数,如下所示:
NotificationCompat.Builder(this,NOTIFICATION_CHANNEL)
也删除了
.setChannelId(NOTIFICATION_CHANNEL)
现在这段代码也适用于三星设备。
