我只是在应用程序处于后台时收到推送通知,我无法找到当我的应用程序接收推送时确切触发的内容。我只想更改通知正文,例如,如果通知消息是" hi"我想向用户" hi user&#34 ;.
public class MyFcmListenerService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage message) {
//nothing triggered here when app is in background
}
}

$fields = array(
'registration_ids' => $reg_id ,
'priority' => "high",
'data' => array(******));
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
我遇到了同样的问题。从我的PHP firebase服务中删除了通知键值。我的问题得到了解决。我只是使用registration_ids
,
priority
,data

你可以,你只需要知道firebase推送通知在android中是如何工作的。
你需要覆盖
handleIntent函数。
此功能在后台处理Firebase通知。因此,在其内部,您将通过推送消息发送所有数据进行推送通知。别忘了从邮件中提取信息。您可以使用标题或正文等默认空格,也可以发送一些自定义数据。
接下来,我将附上示例代码的工作原理。
注意:如果您没有这种方法,那么您需要将firebase版本升级到10.0.1以上
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}
@Override
public void handleIntent(Intent intent) {
//super.handleIntent(intent);
Log.d(TAG,"Handling Intent");
Bundle mBundle = intent.getExtras();
String img = mBundle.getString("imgURL");
String title = mBundle.getString("gcm.notification.title");
String body = mBundle.getString("gcm.notification.body");
mBundle.putInt("promoId",Integer.valueOf(mBundle.getString("promoId")));
Integer id = mBundle.getInt("promoId");
sendNotification(mBundle);
}
private void sendNotification(Bundle mBundle) {
// Create an explicit content Intent that starts the main Activity.
Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
notificationIntent.putExtras(mBundle);
// Construct a task stack.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Add the main Activity to the task stack as the parent.
stackBuilder.addParentStack(MainActivity.class);
// Push the content Intent onto the stack.
stackBuilder.addNextIntent(notificationIntent);
// Get a PendingIntent containing the entire back stack.
PendingIntent notificationPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Get a notification builder that's compatible with platform versions >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
String title = mBundle.getString("gcm.notification.title");
String body = mBundle.getString("gcm.notification.body");
// Define the notification settings.
builder.setSmallIcon(R.mipmap.ic_launcher)
// In a real app, you may want to use a library like Volley
// to decode the Bitmap.
.setLargeIcon(BitmapFactory.decodeResource(getResources(),
R.mipmap.ic_launcher))
.setColor(Color.RED)
.setContentTitle(title)
.setContentText(body)
.setContentIntent(notificationPendingIntent);
// Dismiss notification once the user touches it.
builder.setAutoCancel(true);
// Get an instance of the Notification manager
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Issue the notification
mNotificationManager.notify(0, builder.build());
}
}
