Android Question [ SOLVED] Target SDK 31 widget crash

[Cebuvi]

Hello,

I am upgrading a widget-enabled app to targetSDK 31.
When I install the widget, it does not load and I get an error.

java.lang.RuntimeException: Unable to start receiver com.tempusumbra.solarwidget.solarw4x2$solarw4x2_BR: android.app.ForegroundServiceStartNotAllowedException: startForegroundService() not allowed due to mAllowStartForeground false: service com.tempusumbra.solarwidget/.solarw4x2

Can anyone help me with a solution?

Thanks

As I still can't find a solution, I have tried to start with something simple and from the beginning. With the example of Erel's HomeWidgets.
If I set targetSDK=31, I get this error.

** Activity (main) Resume **
** Activity (main) Pause, UserClosed = true **

If I keep the line Service.StopAutomaticForeground, the same error occurs as I indicated in the previous post.

Has anyone else tried the widgets in targetSDK=31 and is having problems?

 

[agraham]

Why are you targeting SDK 31. The 'official' SDK from the B4A product page is SDK 30. Does your widget work when you target SDK 30?

 

[Cebuvi]

I have received an email from Google with information about new app requirements and among them is a reference to API versions. And as you can see in the attached image, to update an app from November you have to have targetSDK=31 and I have started testing.

 

[agraham]

But does it work targeting SDK 30? If it does it looks, from the error, that Erel may need to adjust some compilation settings and/or update the SDK download to SDK 31.

 

[Cebuvi]

With SDK 30 everything works correctly. I simply changed the manifest to TargetSDK=31 and the errors appeared.

As the app uses StartServiceAtExact, I first added AddPermission(android.permission.SCHEDULE_EXACT_ALARM), because otherwise I got an error telling me that I had to add the instruction.

Thanks

As I indicated above it's a breaking change when targeting SDK 31 that needs Erel's attention

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.

ConfigureHomeWidgets isn't an actual method in core.jar, it looks like a placeholder for the compiler to replace with a call to RemoteViewsWrapper.createRemoteViews.

I think loadLayoutHelper in RemoteViewsWrapper needs modifying to at least set a required flag in its PendingIntent when targeting SDK31 and maybe other changes too.

There is no way to hack this without Erel's involvement.

 

[Cebuvi]

Thank you very much for the reply and the information. It is not an issue that is in a hurry but Erel will be able to solve it.

 

[ilpesce]

Greetings unfortunately the problem has become very urgent ... it is no longer possible to publish sdk30 apps I can't publish an app that contains widgets.

 

[Erel]

Please try the attached update - 11.81.

Make sure to copy to the internal libraries folder.

 

[ilpesce]

thank you very much
Welcome back erel, we hope this SDK31 does not bring us many surprises ...

 

[ilpesce]

Unfortunately the sdk31 + widget problems are not over

[Erel]

This is a different issue.

Try to set the automatic foreground mode to NEVER:

Sub Service_Create
    Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER
End Sub

 

[Cebuvi]

I have tried updating my app and now everything seems to work perfectly. The app doesn't stop, it allows me to add the widgets and they work as with SDK 30.

I think that's solved. Thank you very much Erel for your great work.

 

[ilpesce]

thanks, but it doesn't improve
it seems that the widget can no longer digest
Service.StopAutomaticForeground ecc. it is necessary to delete them all and leave the management completely to the operating system and suffer the relative notification that seems to no longer go away...(maybe?‍)

 

[Erel]

There shouldn't be any notification without a foreground service.

nd leave the management completely to the operating system

This is a behavioral change in Android 12.
