[Christian García S.]

Hello, I have an app with a service #StartAtBoot, this services add Geofence when you restart phone, the same APP has a other services that are active when the APP is running.

One services works with Service.StartForeground.

Sometimes is not always, APP crash, I checked info in play console and I got this message:

Start with posting the FULL ERROR MESSAGE
Or upload a sample project which shows the issue.

I can´t help on the half error

Hi, thanks for your response.

It happens that the application crashes after a few hours, I can not find a way to reproduce the error.

The application is already in production and this error I have obtained from the google developers console (19 crashes reports and 19 with the same error), I can not get more information from there.

Can I find some internal log inside my phone where I can find more details about that error ???

Thanks in advance.

Are you able to reproduce it locally?

The error is related to a CallSubDelayed call where the target sub is missing.

Note that in the next version of B4A an exception will not be thrown in that case.

Hi Erel,

I can not able reproduce locally, how I said this happens in differents hour in day, I have this error code because I saw in google developer console.

I checked code and I have some CallSubDelayed:

Maybe with these CallSubDelayed, you can deduce something.

Thanks a lot.

Hi,

I have an update, you get the notification that you entered the geofence, then a minute later the application crash.

The APP is not open.

I used this tutorial to do that part in the application:

Enable USB debug mode and check the logs after it crashes.
