Android Question Substitute of Starter Service

Rubens Jr. · Apr 25, 2022

Hi !
How can I make a service like the starter service (always runing) as described :

If you are using B4A v8.30+ then the starter service will not be killed until the whole process is killed.
You will see a message such as this one, 60 seconds after the app has moved to the background:
** Service (starter) Destroy (ignored)**

Reason :
My Tablet with Android 11 do not start my app if it has the starter Service !
It shoes a blank screen only.
With an very old other tablet (Android 8.1) This do not happen. My App starts ok every time. (This tablet is a very slow one, about 100 seconds to do a boot)
With another old tablet (Android 9) in 10 times 1 start with a blank screen, 9 ok. This is a not to slow one.
With this brand new ... in 20 times only one starts ok. Even when starts ok, if a touch Home button and start it again : blank screen.
In This same new tablet, an very old App made with B4A version 2.5 the App start ok.

In this new tablet I made a factory reset. Enable usb debug
In B4A (version 11.50) : Start a new project : File -> New -> b4xpages. No modification, just the example.
Compile and run : blank screen.
But, if I remove de Start service and compile and run : Ok ! No problem !! The Click button apears normal.

So .. Is there a way that I make a another service with another name of course than stay running like de start one ?
Thanks

(Sorry by bad english ..)

Not that I'm expert in B4X but from my experience I would try to create simple project not using B4XPages.
I don't expect this project to behave any different versus B4XPages but this is easy way to quickly eliminate question if this is B4XPages related issue ?

Ok. I did it.
File -> new -> Default
Compile and run .. Same result !
Top of screen : B4A Example e no button.
Remove Starter, recompile and works ok. Top of screen : Activity and o button Click.
Add new Service, named it Starter, recompile and again not work.
But The log shows some diferences ! At the end :
Immediately CompilePackage: b4a.example Failed

2. I don't expect this project to behave any different versus B4XPages

But in programing I learned to question everything, just because I been proven wrong many times.
Thank you for pointing out "B4XPages have nothing to do with the Starter." I agree with your statement and point taken.

However why removing Starter Service makes B4XPages appear normally? As we just said B4XPages have nothing to do with Starter.
So this is likely device issue with Starter service. Can we test this?
I think we can? Using simple Default Project with Form and Button, right?

If default project test fails too that will prove what we suspect... but just maybe this is one of these extreme edge cases and starter with default app will work on this guy device? Won't that be worth testing?

BTW
LucaMs, I'm big fan of yours and always read your posts as you are one of the most active members here and I think I learned to pick up your sense of humor in this forum.

Justo to add some information :
I Reboot my tablet and start the same example before (Standart app, not b4xpages) and it works !

With Starter Service sometimes works, sometimes do not work ...

Is this always in debug mode?

I am not expert on this. My guess is the phone is loaded with Custom ROM and kernel which has issue with the mentioned CDM and OEMCrypto L3.

I have the same problem with empty screen showing when i compile a App with Starter-service on a new bought NO-NAME tablet. On phones the app runs perfect, but on the tablet show blank screen and the HOME- Button is not working.
.
The tablet runs Android Go 10 and the connection to the debugger also fails,also when you only start a new project with B4Xpage with no changes. (Hello World- Button does not show up, only blank screen, no HOME-Button working)
Strange thing is, another very big app with many libs runs perfect.
