Android发送本地通知，之前很多方法都收不到通知了，更新完的兼容api26

				Intent intent = new Intent(mContext,TestActivity.class);
                PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);
                final NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                if (Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
                    int importance = NotificationManager.IMPORTANCE_HIGH;
                    @SuppressLint("WrongConstant")
                    NotificationChannel notificationChannel = new NotificationChannel("ID", "NAME", importance);
                    notificationChannel.enableVibration(true);
                    notificationChannel.setShowBadge(true);
                    notificationChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
                    if (notificationManager != null) {
                        notificationManager.createNotificationChannel(notificationChannel);

                }
                NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mContext, "ID");
                mBuilder.setSmallIcon(R.mipmap.ic_launcher);
                mBuilder.setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
                mBuilder.setDefaults(Notification.DEFAULT_ALL);
                mBuilder.setAutoCancel(true);
                mBuilder.setContentTitle("title");

                final Notification notify = mBuilder.build();

                //随机id 1000-2000
                final int notifyId = (int) (Math.random() * 1000 + 1000);
                if (notificationManager != null) {
                    notificationManager.notify(notifyId, notify);
                }
