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 ..)

There is no reason for that. Create a B4XPages and run it. It should work. If not then something is misconfigured.

I Did it. I Created a new project -> b4xpages. Compiled and run ... blank screen
In this empty project if I remove de Start service it run normal : the click button apears ok.

I Did a Factory reset in this tablet and same result : Blank screen

Post the project so we could test it.

There is no Project !
Just : File -> new -> b4xpages
With this 'empty' project just press F5 (Compile and run)

Sorry, I do not understand.
When you create a new project with nothing, what do you expect ?

When this hapens (no click button apears) the back key do not respond either. I Press the back key and the app do not close.

Make sure to have a complete and correct clean install of ALL what is needed to run B4A:
- the IDE
- Java
- Android SDK + Resources
Follow exactly and carefully the steps illustrated here:
B4A Installation
Download all the needed files from the links provided in the steps.
Do not use other external sources.

Ok.
I Formated My PC. Windows 10. None installed.
Installed exactly as in b4a instalation. All works Ok : B4A working good, but ...
Same result. With Starter service appear a blank screen with 'B4A Example' in top of screen and nothing more. The back key do not respond.
If I remove the Starter Service and recompile the example : start ok and Show 'MainPage' in top off screen and the Click button, and the back key close the app as expected.
If I do : Project -> Add new Module -> Service Module and name it Starter .. recompile ... the problem reapears.
I Removed (again) de starter Service, recompile and all ok ...

It could be something related to the tablet/device software.
Not easy to diagnose.

I thing it so ...
My Tablet do not like the starter service ?

Good! Me too (now, with B4XPages) ?

Maybe Erel will understand something in that long log!

teddybear · Apr 26, 2022

I also encountered the similar issue, App is on backgroud after I click BACK-KEY, then I restart it, the screen is a blank ,the title is B4A Example not MainPage. perhaps B4xpages is not compatible with some tablets/TVsets, I will provide some logs for debugging.

1.It is a normal log for operatiing on phone

B4X:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
** Activity (main) Resume **
** Activity (main) Pause event (activity is not paused). **  'Here I clicked Back KEY'
** Activity (main) Resume **    'I restart the APP'

2.Unnormal log , Activity (main) Resume is not called

B4X:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
** Activity (main) Resume **
** Activity (main) Pause event (activity is not paused). ** 'Here Click BACK KEY'
*** Service (starter) Create ***  'Restart APP'

3. I added B4XPage_CloseRequest event (null sub), after clicked BACK-KEY, an exception was thrown

B4X:

*** Service (starter) Create ***
** Service (starter) Start **,
** Activity (main) Create, isFirst = true **
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
** Activity (main) Resume **

Hope it is a clue for solving the issue

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 ?

B4XPages have nothing to do with the Starter.

jerry07 · Apr 26, 2022

This is why I said:

1. Not that I'm expert in B4X
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.
