安卓通知未显示在奇巧上

Question

我试图显示来自火碱消息的通知，它可以在奥利奥及更高版本上运行，但只能在 kitkat 设备上播放声音(我没有其他设备或模拟器进行测试(，我收到一些奇怪的错误日志，例如

Could not find class 'android.app.Notification$Action$Builder', referenced 
from method android.support.v4.app.NotificationCompatBuilder.addAction

我真的很难确定这一点，所以这是代码的主要内容

private void sendNotification(Map<String, String> data) {
String author = data.get("USER_NAME");
String title = data.get("TITLE");
String body = data.get("BODY");
String id = data.get("USER_NUMBER");
String message = data.get("MESSAGE");
String type = data.get("TYPE");
String image = data.get("IMAGE");
String profileImage = data.get("USER_IMAGE");
String shortMessage = "";
Intent intent;
Bitmap bitmap;
Bitmap bitmap2;
intent = new Intent(this, MessageListActivity.class);
if (MessageListActivity.isAppRunning)
intent = new Intent(this, MainActivity.class);
intent.putExtra(Constants.USER_NAME, author);
intent.putExtra(Constants.USER_NUMBER, id);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
/*
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(intent);
*/
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
/*
String replyLabel = getString(R.string.notif_action_reply);
RemoteInput remoteInput = new RemoteInput.Builder(KEY_REPLY)
.setLabel(replyLabel)
.build();
*/
// If the message is longer than the max number of characters we want in our
// notification, truncate it and add the unicode character for ellipsis
if (message.length() > NOTIFICATION_MAX_CHARACTERS) {
shortMessage = message.substring(0, NOTIFICATION_MAX_CHARACTERS) + "u2026";
}
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
if (type.equals("IMAGE")) {
bitmap = getBitmapfromUrl(image);
bitmap2 = getBitmapfromUrl(profileImage);
notificationBuilder
.setLargeIcon(bitmap2)
.setSmallIcon(R.drawable.message_me)
.setContentTitle(String.format(getString(R.string.notification_message), author))
.setStyle(new NotificationCompat.BigPictureStyle()
.setSummaryText(shortMessage)
.bigPicture(bitmap))
.setContentText(message)
.setColor(getResources().getColor(R.color.colorPrimary))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
} else if (type.equals("TEXT")) {
bitmap2 = getBitmapfromUrl(profileImage);
notificationBuilder
.setSmallIcon(R.drawable.message_me)
.setLargeIcon(bitmap2)
.setContentTitle(String.format(getString(R.string.notification_message), author))
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(message))
.setContentText(shortMessage)
.setColor(getResources().getColor(R.color.colorPrimary))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN
&& Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
notificationBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
getManager().notify(0 /* ID of notification */, notificationBuilder.build());
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
notificationBuilder = getChannelNotification(title, body, shortMessage, SINGLE_CHANNEL_ID, pendingIntent, type, image, profileImage);
getManager().notify(0, notificationBuilder.build());
}
}

private NotificationManager getManager() {
if (mManager == null) {
mManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
}
return mManager;
}

所有数据都存在并更正我从中得到的第一个错误是

Could not find class 'android.app.NotificationChannel', referenced from 
method com.sealstudios.aimessage.MyFirebaseMessagingService.createChannels

我的创建通道方法是这个

@RequiresApi(api = Build.VERSION_CODES.O)
public void createChannels() {
// create single channel
NotificationChannel singleChannel = new NotificationChannel(SINGLE_CHANNEL_ID,
SINGLE_CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);
singleChannel.enableLights(true);
singleChannel.enableVibration(true);
singleChannel.setLightColor(R.color.colorPrimary);
singleChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
getManager().createNotificationChannel(singleChannel);
// create group channel
NotificationChannel groupChannel = new NotificationChannel(GROUP_CHANNEL_ID,
GROUP_CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
groupChannel.enableLights(true);
groupChannel.enableVibration(true);
groupChannel.setLightColor(R.color.colorPrimary);
groupChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
getManager().createNotificationChannel(groupChannel);
}

但这只从 onMessageReceived 在 if 括号中调用，如下所示

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Check if message contains a data payload.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
createChannels();
}
if (remoteMessage.getData().size() > 0) {
Map<String, String> data = remoteMessage.getData();
if (data.size() > 0) {
if (!(chatActive && remoteMessage.getData().get("USER_NAME").equals(senderID))) {
//TODO add a mute notifications
sendNotification(data);
}
}
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
}
}

如前所述，我从单独的方法获得完整的通知，而无需担心android Oreo，

这是

@RequiresApi(api = Build.VERSION_CODES.O)
public NotificationCompat.Builder getChannelNotification(String title, 
String body, String smallMessage, String channelId,
PendingIntent pendingIntent, String type, String largeImage,
String smallImage) {

if (type.equals("TEXT")) {
Bitmap smallBitmap = getBitmapfromUrl(smallImage);
return new NotificationCompat.Builder(getApplicationContext())
.setChannelId(channelId)
.setContentTitle(title)
.setStyle(new NotificationCompat.BigTextStyle().bigText(body))
.setContentText(body)
.setColor(getResources().getColor(R.color.colorPrimary))
.setSmallIcon(R.drawable.message_me)
.setLargeIcon(smallBitmap)
.setContentIntent(pendingIntent)
.setAutoCancel(true);
} else if (type.equals("IMAGE")) {
Bitmap smallBitmap = getBitmapfromUrl(smallImage);
Bitmap largeBitmap = getBitmapfromUrl(largeImage);
return new NotificationCompat.Builder(getApplicationContext())
.setChannelId(channelId)
.setContentTitle(title)
.setStyle(new NotificationCompat.BigPictureStyle().setSummaryText(smallMessage).bigPicture(largeBitmap))
.setContentText(body)
.setColor(getResources().getColor(R.color.colorPrimary))
.setSmallIcon(R.drawable.message_me)
.setLargeIcon(smallBitmap)
.setContentIntent(pendingIntent)
.setAutoCancel(true);
}
return new NotificationCompat.Builder(getApplicationContext())
.setChannelId(channelId)
.setContentTitle(title)
.setContentText(body)
.setColor(getResources().getColor(R.color.colorPrimary))
.setSmallIcon(R.drawable.message_me)
.setContentIntent(pendingIntent)
.setAutoCancel(true);
}

但除此之外，我只会收到通知声音，我敢肯定，在我将目标 SDK 提高到 27 之前，它曾经有效，但任何帮助将不胜感激

这看起来像是通过更新 gradle 插件修复的
