API 低于 26 的 Android 上会收到 Android fcm 通知，但 API 26(Oreo 8.0) 不会收到，这会导致应用程序崩溃

最佳答案
我认为您使代码变得不必要的复杂。
尝试下面的代码
private void createNotification(String title, String message) {
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// only create notification channel if SDK >= 26
if (android.os.Build.VERSION.SDK_INT >= 26) {
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);
channel.enableLights(false);
channel.enableVibration(true);
channel.setDescription(CHANNEL_DESC);
manager.createNotificationChannel(channel);
}
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(android.R.drawable.stat_notify_more)
.setContentTitle(title)
.setSmallIcon(R.mipmap.ic_launcher)
.setSound(defaultSoundUri)
.setColor(ContextCompat.getColor(this, R.color.colorAccent))
.setContentText(message);
manager.notify(new Random().nextInt(), builder.build());
}
关于java - fcm 通知崩溃仅适用于 api 26，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58958162/
