[英]How to implement FCM push notification in unity for android devices that works even when game is killed
[英]How to send push notification to android devices even when app is killed?
当应用程序处于前台和后台时,我可以发送通知。 但是当应用程序被杀死时无法发送它,即应用程序不在后台运行。 我手机中的其他应用程序即使在后台运行时也能向我发送通知。 我正在使用奥利奥版本。
我也用“数据”替换了“通知”,这并没有什么不同。 我已经在 onMessageReceived 方法上添加了自定义通知,“通知”和“数据”都在前台和后台提供通知。 唯一的区别是“数据”也在后台运行 onMessageReceived 方法。 但是在两者上,当应用程序被杀死时都没有收到通知。我尝试过在 php 上执行以下代码。 我究竟做错了什么?
function sendPushNotification($token) {
$url = "https://fcm.googleapis.com/fcm/send";
$serverKey = 'AAAA.....theKey';
$title = "My App";
$body = "hello there!!";
$notification = array('title' =>$title , 'body' => $body, 'sound' => 'default', 'badge' => '1');
$arrayToSend = array('to' => $token, 'notification' => $notification,'priority'=>'high');
$json = json_encode($arrayToSend);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: key='. $serverKey;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
//Send the request
$response = curl_exec($ch);
//Close request
/* if ($response === FALSE) {
die('FCM Send Error: ' . curl_error($ch));
}*/
curl_close($ch);
// echo "<br>";
return $response;
}
在 onMessageReceived 方法中:
对于“通知”:
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d("apkflow","onMessageReceived Started");
if (remoteMessage.getNotification() != null) {
title = remoteMessage.getNotification().getTitle();
body = remoteMessage.getNotification().getBody();
Log.d("apkflow","title = " + title);
Log.d("apkflow","body = " + body);
}
}
对于“数据”:
title = remoteMessage.getData().get("title");
body = remoteMessage.getData().get("body");
更新::我现在得到了解决方案!! 这是由于移动最近更新。 在vivo、oppo、xiomi等手机中,当app清空后,强制停止app,强制停止所有服务。 因此,FCM 服务也将停止,并且在移动设备上不会收到任何通知。 因此,要获得通知,用户必须允许应用程序在后台运行“允许在后台运行”必须被选中。 这解决了问题。 如果您还有问题,请发表评论!!
在后台接收时具有通知和数据负载的消息。
更改notification
类型data
$arrayToSend = array('to' => $token, 'data' => $notification,'priority'=>'high');
请阅读以下文档https://firebase.google.com/docs/cloud-messaging/android/receive
您必须创建自定义通知。
private void setNotification(RemoteMessage content) {
Log.d(TAG, "custom notification: ");
Intent intent = new Intent(this, NotificationActivity.class);
if (!content.getData().get("url").isEmpty())
intent.putExtra("url", content.getData().get("url"));
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setAction(Long.toString(System.currentTimeMillis()));
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
RemoteViews remoteViews = new RemoteViews(getPackageName(),
R.layout.custome_notification);
remoteViews.setTextViewText(R.id.tvTime, currentDate());
remoteViews.setTextViewText(R.id.text, content.getData().get("text"));
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, getPackageName())
.setSmallIcon(R.drawable.ic_alert)
.setContent(remoteViews)
.setAutoCancel(true)
.setSound(defaultSoundUri);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// To avoid replacing old notification by new one. To set new id for every new Notification following notifications.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel(getPackageName(), "AppName", importance);
notificationManager.createNotificationChannel(mChannel);
}
int notifyId = (int) System.currentTimeMillis();
notificationManager.notify(notifyId, notificationBuilder.build());
}
