Hi Erel

Ok, now we getting somewehere
Seems like the Java error STOPPED, but google now prevent Auth

11/29/2015 16:26:28: Error: (RuntimeException) java.lang.RuntimeException: Error during login: -ERR [AUTH] Web login required: https://support.google.com/mail/answer/78754

Run the command as suggested.
Program still give me an error, and then I received this on my mobile

Someone just try to sign to your Google account xxxx@gmail.com from an app that doesn't meet modern security standards

I've checked, Double check my settings/Password. Everything seems fine

Thanks

HI Erel

Thanks, got the B4J app going (After Less Secure email) , Now the B4A app, when enter a name and register it says
INVALID_SENDER

Thanks
Danie

 

[Erel]

I'm sorry but your question got lost (I think) between the two threads. If the issue in this thread was resolved then you should start a new thread for a new question.

 

[daniedb]

Ok, got basically everything sorted. Program Compiles fine. Android APP (Device) when register detect in B4J APP

Now, when I try to send a message I get the following Error
12/03/2015 20:02:48: Error sending message: Unauthorized

Why wil it be Unaithorized when trying to sedn with the b4J app

Thanks
Danie

 

[Erel]

Where is this message printed? From the Android app?

It probably means that the SMTP password is incorrect.

 

[daniedb]

Hi Erel
Check en recheck password. Also email address
It's printed in the Bj4 Email APP.
The Android APP runs fine and I can register to the B4J Email APP
I can receive messages in the B4J app. But as soon as I try to send a message from the B4j App to selected device/s it fails authetication

Thanks
Danie

 

[Erel]

It is not related to the email password.

The problem is with the Google account configuration. You need to start with this tutorial: https://www.b4x.com/android/forum/t...ion-gcm-framework-and-tutorial.19226/#content
Once it works, switch to the email based solution.

Thanks Erel. Got this sorted. I created the Wong API key in Google, Now Ive got it, aswell as a valid Project ID

Appreciate all the help
