Is there a code example for b4a? or only for b4J?

You should read the tutorial..
Example attacched is for b4a. Is also attacched a b4j code to send the message. Code is the same of b4a

Ok, I trying the example to first post but I have the error compiling in this part of code:

Sub Service_Start (StartingIntent As Intent)
    If StartingIntent.IsInitialized And fm.HandleIntent(StartingIntent) Then ReturnAnd
End Sub

the error is :

Error description: Undeclared variable 'returnand' is used before it was assigned any value.
Error occurred on line: 46 (Main)
If StartingIntent.IsInitialized And fm.HandleIntent(StartingIntent) Then ReturnAnd

I included FirebaseNotifications and Core Library.

if you use copy and paste: DO IT RIGHT!!

Sub Service_Start (StartingIntent As Intent)
   If StartingIntent.IsInitialized AND fm.HandleIntent(StartingIntent) Then Return
End Sub

 

[Walter Scafati]

Ops .. Sorry!

Then, I compiled the App but not receive the msg.
I did all these steps:

1. created a new project in firebase
2. used the same name of Android Packet in the App Project
3. Add the manifest snippets to the manifest editor
4. put the json file in the b4a folder
   
5. sent the msg from firebase console

what I forgot?

 

[Walter Scafati]

Found the problem, I've forgot a part in the manifest.
Now I receiving the push msg with "Null" text and "Null" label when the app is showed but with correct message when the app is in background. Why?

1. If you see an example here, please use it strictly "as it is" first to prevent unnecessary mistakes like typos
2. Please send the messages from B4J (as the example provides)
3. Why via B4J? So you can manage what you send and you can see/check what the Google api returns (like "successful", "fail" and a reason)
4. Learn what a map is (take a search)
5. As you will see, the line

 n.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"), Main)

is trying to get "title" and "body". I assume that what you send via console does not contain a map with these keys. So it's NULL.

6. If you get errors or you have questions, please post your code AND logs together. You could have posted the output of these line (from the example)

Log($"Message data: ${Message.GetData}"$)

It contains the map of the message which was sent. If you take a look at it, you will not find "title" and "body". The next logical step is to change the map which was sent or the code of the receiver.

Hi,
I don't know B4J and I never used it. However, I downloded and installed it. I compiled the FCMPush project and made the .jar file. Then I downloaded the B4J Package project and compiled it. Then when I tryed to buid the FCMPush.jar I receive the "Error parsing manifest file".
What can be the error?

 

[Erel]

Just run the project from the B4J. Don't compile it to a library.

 

[Walter Scafati]

Yes, without to compile it works. Thanks Erel!
But is possible make the app for to send the push notifications or must I realize a PHP page for to perform this?

 

[Erel]

or must I realize a PHP page for to perform this?

You never ever need to use PHP if you use B4A and B4J.

Go over the very simple code, understand it and implement it in your B4A program if you like.

 

[Walter Scafati]

Thank Erel,
Yes is true. I moved the code in b4a and it works fine.
