Android Question errors on sdk 31 - b4A ver 12 - Unable to start receiver

[alon]

Hi ,

Since upgrading to sdk 31 I am having a few problems and the app crash.

I read all the posts about the new sdk problems.

And I did the following:

I start using StartServiceAtExact

add to manifest: <uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM"/>

add Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER to the Service_Create (of the firebase service)

Sub Service_Create



fm.Initialize("fm")

Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER '05-12-2022



End Sub

But still have problems.

I am using B4A ver 12

You must sent messages with high priority. Use the updated B4J code to send the messages.

Hi Erel,

Thanks for you help.

But I am not sure I understand.

I am sending the messages with http request from sql server of my client.



If you mean that I should pop up the messages with high priority from b4a, then I will try to send it like this:

Dim n As Notification

n.Initialize2(n.IMPORTANCE_HIGH) 

n.Vibrate = True

n.Icon = "notifyicon"

n.AutoCancel = True

Can you please show me how to send from updated B4J.



Thanks In Advance

Can you please show me how to send from updated B4J.

Hi Erel,
According to your answer and the b4j code,
I understand that your first answer was that I should post the message with "priority" : 10 .

Am I correct?

 

[DonManfred]

yes

 

[alon]

yes

thanks donmanfred,
I will try that.
