Background.exit cause app crash SDK4

Rick over 4 years ago

My app is crashing on Background.exit() in SDK 4.0.7 and 4.0.8. SDK 4.0.6 is ok.

Has anyone come across this problem ?

Not using Eclipse anymore. Uninstalled.

VSCode + SDK 4.1.0Beta1 runs OK. However not using it as I can't replay FIT files.

Tried with 4.0.8 with run without debugging. Crashed the same.

Ok - memory usage is the same between SDK4.0.6 and 4.0.7 and 4.0.8. SDK 4.1.0 Beta is slightly different but it also works correctly.

SDK4.0.8:

Background: Returning background data

Background: Free:45360 Used:16000 Total:61360

Encountered app crash.

SDK 4.0.7:

Background: Returning background data

Background: Free:45360 Used:16000 Total:61360

Encountered app crash.

SDK 4.0.6

Background: Returning background data
Background: Free:45360 Used:16000 Total:61360
onBackgroundData: {XXXXXXXX}
onReceive: false : {XXXXXXXXXX}

SDK 4.1.0 Beta

Background: Returning background data
Background: Free:45336 Used:16000 Total:61336
onBackgroundData: {XXXXXXXXXX}
onReceive: false : {XXXXXXXXXXX}

This is still a problem in SDK4.1.3 on MacOS with VS

How much data are you trying to pass in Background.exit()? Try reducing the amount of data (maybe 1/2 as much) and see if you still get the crash. Maybe even start with something really simple - (like 100 bytes)

Hi Jim, I'm normally returning a date string so around 10 bytes. I've just confirmed that the app crashes in the simulator with

Background.exit(null); or

Background.exit("");

as well, so I don;t think it relates to the data size.

This is only a problem in the simulator. It works ok in the app and I can get it to work in the sim if I drop back to SDK4.0.6.

(Mac OS 12.3.1, VS Code 167.2, SDK > 4.0.6)
