我收到了来自服务器的多个通知。但问题只是最近通知重定向到应用程序。对于所有其他通知，单击通知时，应用程序未打开。这只发生在我的服务器上。如果我从FCM控制台发送多个通知，则所有通知都会重定向到应用程序。为什么这样开心呢？
下面是Json解析代码
private void handleDataMessage(JSONObject json) {
Log.e(TAG, "push json: " + json.toString());
try {
JSONObject data = json.getJSONObject("data");
String title = data.getString("title");
String message = data.getString("message");
boolean isBackground = data.getBoolean("is_background");
String imageUrl = data.getString("image");
String timestamp = data.getString("timestamp");
String payload = data.getString("payload");
Log.e(TAG, "title: " + title);
Log.e(TAG, "message: " + message);
Log.e(TAG, "isBackground: " + isBackground);
Log.e(TAG, "payload: " + payload.toString());
Log.e(TAG, "imageUrl: " + imageUrl);
Log.e(TAG, "timestamp: " + timestamp);
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
// app is in foreground, broadcast the push message
Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
pushNotification.putExtra("message", message);
pushNotification.putExtra("title", title);
LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
// play notification sound
NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
notificationUtils.playNotificationSound();
} else {
// app is in background, show the notification in notification tray
Intent resultIntent = new Intent(getApplicationContext(), MainActivity.class);
resultIntent.putExtra("message", message);
// check for image attachment
if (TextUtils.isEmpty(imageUrl)) {
showNotificationMessage(getApplicationContext(), title, message, timestamp, resultIntent);
} else {
// image is present, show notification with image
showNotificationMessageWithBigImage(getApplicationContext(), title, message, timestamp, resultIntent, imageUrl);
}
}
sendNotification(title, message);
} catch (JSONException e) {
Log.e(TAG, "Json Exception: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
这是通知生成代码
private void sendNotification(String title, String message) {
Intent intent = new Intent(MainMenuPage.this, ComplaintList.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
Notification n = new Notification.Builder(this)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.drawable.icon)
.setContentIntent(pIntent)
.setAutoCancel(true)
.build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, n);
}

使用以下代码发送通知解决此问题
Notification n = new Notification.Builder(this)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.drawable.icon)
.setContentIntent(pIntent)
.setAutoCancel(true)
.build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
int m = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
notificationManager.notify(m, n);
需要始终发送不同的通知ID。

尝试以下代码对您有用：
private void sendNotification(String message, String contentTypeId, String contentId) {
if (notifManager == null) {
notifManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
}
boolean isAppVisible = BaseActivity.count > 0;
boolean isNotificationSound = true;
//TODO: update count if app is open.
if (isAppVisible) {
if (isNotificationSound) {
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
r.play();
} catch (Exception e) {
}
}
sendMessage(message, contentTypeId, contentId);
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_HIGH;
assert notifManager != null;
NotificationChannel mChannel = notifManager.getNotificationChannel(CHANNEL_ID);
if (mChannel == null) {
mChannel = new NotificationChannel(CHANNEL_ID, getString(R.string.app_name), importance);
mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
notifManager.createNotificationChannel(mChannel);
}
builder = new NotificationCompat.Builder(this);
Intent intent = new Intent(this, SplashActivity.class);
intent.setAction(Intent.ACTION_MAIN);
// intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.putExtra(AppConstants.EXTRAS.IS_NOTIFICATION, true);
intent.putExtra(AppConstants.EXTRAS.CONTENT_ID, contentId);
pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentTitle(getString(R.string.app_name)) // required
.setSmallIcon(getNotificationIcon()) // required
.setContentText(message).setWhen(System.currentTimeMillis()) // required
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setContentIntent(pendingIntent)
.setChannelId(CHANNEL_ID)
.setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
} else {
builder = new NotificationCompat.Builder(this);
Intent intent = new Intent(this, SplashActivity.class);
intent.setAction(Intent.ACTION_MAIN);
// intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

.setPriority(Notification.PRIORITY_HIGH);
}
Notification notification = builder.build();
notifManager.notify(Integer.parseInt(contentId), notification);
}
}
private void sendMessage(String message, String contentTypeId, String contentId) {
