Some apps do not work while watch is connected to phone

@NIKEOW I've actually been keeping an eye on your thread (https://forums.garmin.com/showthread.php?339791-IQ!-Without-any-error-logs-How-to-debug), but have been waiting to see if there's any more information about the circumstances around the crashes you're seeing. There were a few suggestions from other devs that were keeping the conversation moving, but it appears to have stalled out. :)

Using System.println() statements is still the best way to try to trace through the app to get you close to the point of failure. If that gets you nowhere, since there's no CIQ_LOG file, we may be able to help debug the app. I'll contact you privately to follow up.

Thanks for the info Brandon.

I will have some time during the next weekend and will produce a crash dump to send to you guys.


Taking advantage of this contact, I will ask some hard to answer questions that maybe you can foward to CIQ team. :D

I understand memory issues fragmentation, but there is little we devs can do if we don't know were are the traps.

I will ask some direct questions that maybe you can forward to CIQ dev team.
Plase consider that my app now uses 48K when it starts and when its crashs its always on startup

1) When my app starts I immediately start sensors and GPS based on user preferences. Delaying this process some seconds could make it easyer to the VM relase the necessary memory?

2) The number of sensors enabled have significant diference in memory usage during sensor startup? (today I simply start all sensors, should I change this approach)?

3) I talked to Robs_1976 (https://apps.garmin.com/en-US/apps/2e096d91-3e49-492f-9bd1-e5c92a53d1a5) and he told me some of his users reported that started the app indoor, and when they gone outdoor and GPS fixed, the app crashed. This is really a huge problem and it seems like the watch took away the memory available to the app. There is some way to avoid this?

4) I always worked based on the assumption 64K was my limit. I see that this limit is not real. Could you guys provide a guideline of how much memory is safe to use? I believe it should be better to assume a lower limit and not frustrate the users and devs with unreal expectations. Crashing apps are uggly!! :p

5) And finally! It's really important you guys provide us some info on what aproaches (coding techniches) could help us save memory and resources. After all, you better than us know the weaknesses of your compiler and VM. I know you guys understand that to have a greater diversity of apps in the store, we will have to use a lot of creativity and will have to squeeze everything from the devices. All help is welcome!

I don't expect you will have a fast answer for all questions :-D

Thanks again!!

Cheers,

Robinson

AHH! I just noticed the forum post is moderated! I will stop sendind the same message 3 times!

You can ignore this one! Cheers!

Thanks Brandon.. I have responded.

COming back to this.. there are no easy way to reproduce it.. I have managed to get it out of the way most times with a reboot or just going into native app.
I am, like robinsomilani also pushing the app size.. 48kb or such.. and I have also found that more issues happen as I edge up the memory on startup. ( I allocate 10-12kb for the menu system)

From the users, it tycpically happens on startup. it will be like - yesterday is Good.. Then suddenly today it's IQ!
I asked them to reboot or go into native app and then return to the app and sometimes it works, sometimes it doesnt. Sometimes need to reinstall.

I try VERY hard to reduce memory usage.. hence the SDK increase of 3kB or even 1kB is a LOT to me. That's Y i am still staying on 1.2.1

Thanks for the info Brandon.

I'm going to check into a couple of things before responding so I can make sure I'm getting your the correct info. :)

I Generated the memory dump today and sent to Garmin guys.

There was no CIQ error file generated.

@robinsonmilani: Thanks--I have your log files here and will get this information forwarded for investigation. I appreciate you taking the time to collect the logs for me!

Just wondering if there are updates on this?

I have not. It's sparodic for me. Happens 1/50 times or such.
Robinsonmilani sent the log files - didn't that yield anything?

I also sent my source code for my app as well.
