Numerous Unknown Android Preview Errors

Bug Reports

Hi Fuse Team Memebers,

Everytime I go about running Fuse Android Preview I get a log of rejections, skipping, blockage …etc. But the app does run, therefore I’m okay. Anyhow, this log does frigthen me and I wonder how my app, built with Fuse is operating internal, as well as performance. Here is the log:

I’m wondering if I’m doing anything wrong that is causing this? Is this normal?

It’s not a comfortable sight to see so many Frames that are “skipped”, “too much work on it’s main thread”, or … “is null”, or … “rejecting”, …etc.

Would be nice to understand this in depth.

Thanks.

Elizabeth

Hi Elizabeth, Sorry to hear about the issues you are having there. Could you give us a little info to aid in the process of finding the issue?

Knowing your device & model and also the OS version would help a lot.

Regards, Chris

My Device Details:

Model = LG-P705g OS Version = Android 4.1.2

Thanks I will ping some of the folks that focus on performance so we can have a look at this. Does this happen when previewing our example apps too?

We take performance very seriously an those skipped frames certainly shouldnt be happening. We render our UI on the android UI thread (making sure to keep that very fast) and JS runs in a seperate thread. So unless there are some operations blocking the UI thread this shouldnt be happening. If this is only happening on your own app then would you mind sending that project to https://www.dropbox.com/request/ZgndLtJQm5eGzG9cicGK?

Thanks for the report

Hi Chris.

I took time out today to do some testing.

Ran Minimum of three times Android App Preview on:

#1. Pull To Refresh = Both First time no errors. Second time errors and square black icons. Third time I uno cleaned, still got errors but icons okay.

#2. Swipe Places and Pages using JS = Errors all three times. Pages Using JS icons black twice, once okay.

*Note: I tried with and without other apps running, as well as uno clean projects … results were the same. It seems the skipped is always there but the very bottom errors are once and a while. :expressionless:

Hope this helps! :smiley:
