Why will the out of memory error occured when the peak memory isn't reached

I was trying to get a qrcode bitmap from the storage use

Storage.getValue("wimg")

, but to get an error

Out Of Memory Error Details: Failed invoking <symbol> Stack: - onUpdate() at /Users/kent/AwesomeJumpingRope/source/ui/PayQrCodeView.mc:80 0x100004dd

When checking the memory, I found the peak was not reached

I think the size of the qrcode is less than 8kb. Is there anyway to check the size of the bitmap?

I couldn't find the object size of my bitmap from the internet in the memory inspector

In memory viewer you can see only this peaks that were already allocated

Yep. But the image was fetched from the internet and stored as a bitmap in Storage. Why cann't I view the memory allocation? I don't understand it. THX

You haven't shown code so I can only guess...

0. is fetched but probably in background and it has his own memory

1. error is in onUpdate - it's not good to read something in onUpdate - it costs a lot of battery

2. you can't view memory for object not loaded into memory yet

3. try it

- make member mBitmaptest

--next assign mBitmaptest =Storage.getValue("wimg")

- run app for nother device with more memory (venusq has only 92kb when WF) e.g. f6p and than go to monitor and find mBitmaptest and you will see memory ocupation
