几个Android O通知问题:
1)我创建了一个通知通道(见下文),正在使用 .setChannelId() 调用构建器(传入我创建的通道的名称,“wakey”;但是,当我运行应用程序时,我收到一条消息我未能向频道“null”发布通知。可能是什么原因造成的?
2)我怀疑#1的答案可以在它说要检查的“日志”中找到,但我已经检查了logcat并且没有看到任何关于通知或频道的信息。它说要查看的日志在哪里?
这是我用来创建频道的代码:
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence name = context.getString(R.string.app_name);
String description = "yadda yadda"
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL, name, importance);
channel.setDescription(description);
notificationManager.createNotificationChannel(channel);
这是生成通知的代码:
Notification.Builder notificationBuilder;
Intent notificationIntent = new Intent(context, BulbActivity.class);
notificationIntent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND); // Fix for https://code.google.com/p/android/issues/detail?id=53313
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
Intent serviceIntent = new Intent(context, RemoteViewToggleService.class);
serviceIntent.putExtra(WakeyService.KEY_REQUEST_SOURCE, WakeyService.REQUEST_SOURCE_NOTIFICATION);
PendingIntent actionPendingIntent = PendingIntent.getService(context, 0, serviceIntent, PendingIntent.FLAG_CANCEL_CURRENT);
_toggleAction = new Notification.Action(R.drawable.ic_power_settings_new_black_24dp, context.getString(R.string.toggle_wakey), actionPendingIntent);
notificationBuilder= new Notification.Builder(context)
.setContentTitle(context.getString(R.string.app_name))
.setContentIntent(contentIntent)
.addAction(_toggleAction);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
notificationBuilder.setChannelId(NOTIFICATION_CHANNEL);
}
notificationBuilder.setSmallIcon(icon);
notificationBuilder.setContentText(contentText);
_toggleAction.title = actionText;
int priority = getNotificationPriority(context);
notificationBuilder.setPriority(priority);
notificationBuilder.setOngoing(true);
Notification notification = notificationBuilder.build();
notificationManager.notify(NOTIFICATION_ID, notification);
