Android Question [Solved] "Failed to allocate memory" error

[Branksey]

My app has been working perfectly for months, and I wanted to modify it slightly. I added two lines of code to a service module (comms) and I get a "failed to allocate memory" error message immediately after the app has loaded.
If I comment out those two lines of code, I don't get the error.
If I set a breakpoint on the two lines of code, the breakpoint is not hit.
The two lines of code are not in the "starter" service where the error is reportedly happening at line 107.
I don't expect anyone to solve the issue from these brief details, but perhaps someone can help me understand what the error log is saying, and suggest possible solutions.
Many thanks.

: Failed to allocate a 184560016 byte allocation with 6291456 free bytes and 58MB until OOM

What is the reason to try to allocate 184560016 bytes? What are you doing here? That´s 184 MB...

 

[Branksey]

Thank you for your reply.
Yes, I know. I'm not doing anything that requires such a huge amount of memory. I'm simply receiving a text string of formatted data and displaying it in a table. It feels like a memory leak, but I can't see any possible reason for that. The fact that I can make it go away by commenting out two lines of code, and yet those lines of code are never executed is the most puzzling thing for me.

 

[DonManfred]

I can not further help with this less infos you provided.

Upload a small project showing the problem.

 

[Branksey]

I'm trying to isolate it into a small project, but it's very difficult. Thank you your help.

 

[Branksey]

I have managed to reproduce the OOM problem with a tiny project. I have put comments against the lines that will prevent the crash if they are removed. None of this makes any sense to me, so I'm hoping that it makes sense to someone.
Many thanks for any help.

 

[agraham]

That project does not throw any error on load for me.

 

[Branksey]

I am running it on an Android 10 tablet via a USB cable, in debug mode, if that makes a difference. I am using B4A 12.20 (64 bit).

Here is the error log:

UPDATE:
It also crashes on an Android 9 phone and on an Android 6 phone.
I installed B4A on another computer, and it also crashes when using that one, so it doesn't seem to be related to my computer or target device.

 

[William Lancee]

I tested this. Like @agraham I did not have any problems. I saw some missing subs, but adding them did not change things.
I added logs. ???

 

[Branksey]

Thank you for your reply. Running your project in Release mode via a USB cable I do not get the OOM error:

---

*** Service (starter) Create ***
Here 3
Here 4
** Service (starter) Start **
** Activity (main) Create (first time) **
Here 9
** Activity (main) Resume **
*** Service (comms) Create ***
** Service (comms) Start **

---

However, running it in Debug mode via a USB cable I still get the error. There is a 5 second delay after the "Here 4" before the OOM error occurs:

[William Lancee]

@Branksey , yes that gives me the same error as you.

If it only happens in debug mode, it could be a timing problem.
Perhaps Comms does not yet fully exist after Here 4, which restarts Starter and we have an infinite loop.

 

[Branksey]

@WiL, that's certainly a possible explanation. If I set a break point and step through the code the error doesn't happen, which supports your theory. I'm just surprised that I've never encountered this type of error before. Many thanks for your time and help, it's greatly appreciated.
