Android Question Firebase push notification

uniplan · Mar 13, 2017

Hi, i followed this example to sent a notification push.

https://www.b4x.com/android/forum/t...-messages-firebase-cloud-messaging-fcm.67716/

I'm not included the last part where you can send the message to topic.
I'm interested only on the part where you can sent the message from firebase to all devices.

I test it and i receive the notification push, but the title and body are null.
you can help me about this problem?
Thank you for your help

Are you using the B4J code to send the message?

KMatle · Mar 13, 2017

The firebase console is just a little helper and not ment to be to send messages generally. Use The B4J example to send the messages.

To the null values: Check the content of "Message.GetData" (just log it and see what is sent)

Firstly i used the firebase console and i receive the push notification, but it's null.
Now i'm testing the B4J example but receive this message in console:

Waiting for debugger to connect...
Program started.
<HTML>
<HEAD>
<TITLE>Unauthorized</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Unauthorized</H1>
<H2>Error 401</H2>
</BODY>
</HTML>

, password=, errormessage=Unauthorized, target=class b4j.example.main

, httputils2service=null]
Program terminated (StartMessageLoop was not called).

Message.GetData is empty....
in console:
Message data: {}

Maybe you haven't created succesfully your Firebase Project at FB console developer ; have you follow the https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/ steps ??

I follow correctly this steps...only part that i not added is this:

'************ Firebase Ads ************AddApplicationText(
<activity
android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
android:theme="@android:style/Theme.Translucent" />
<activity android:name="com.google.android.gms.ads.purchase.InAppPurchaseActivity"
android:theme="@style/Theme.IAPTheme"/>
)'************ Firebase Ads (end) ************

Becouse i receive this error
AndroidManifest.xml:155: error: Error: No resource found that matches the given name (at 'theme' with value '@style/Theme.IAPTheme').

Now i added the FirebaseAdMob library and i haven't this error message...but already push is null

The strange behaviour is the B4J program...that display this message in console:
<HTML>
<HEAD>
<TITLE>Unauthorized</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Unauthorized</H1>
<H2>Error 401</H2>
</BODY>
</HTML>
[jobname=fcm, success=false, username=
, password=, errormessage=Unauthorized, target=class b4j.example.main
, taskid=1, req=anywheresoftware.b4h.okhttp.OkHttpClientWrapper$OkHttpRequest@70177ecd, tag=java.lang.Object@1e80bfe8
, httputils2service=null]
Program terminated (StartMessageLoop was not called).

I solved it!
I found this post ....
https://www.b4x.com/android/forum/threads/setting-up-firebase-messaging-in-5-minutes.73569/
i changed tha API KEY in the B4J program.
I used the token and not server key.

uniplan · Mar 13, 2017

Only one question:

Hi, i used this Tutorial :
https://www.b4x.com/android/forum/threads/setting-up-firebase-messaging-in-5-minutes.73569/
and B4J example work fine in the "SendMessageToTopic", but in
SendMessageToSingleDevice i received the null data (like as firebase console), you can know why?
Thank you

No sorry, I don't know; I've only tested sending to topic

Please post the complete OkHttp-Job (remove your key

) plus the content of "Message.GetData" when the message arrives).
