I have a minimalistic working example at playground.timmyrs.de/rip

Works on Android 6, too. However, not on iPhone, as they don't seem to have that notification.

We should throttle the frequency of notification update. Otherwise System UI is refreshing all the time causing this failure.

1. It could be something Issue 346215?
2. Second I think we should just sanitize the title (and other fields we use in the notification) somewhere so we don't allocate too much ram to store it?

Throttling notification updates sounds like just delaying the OOM issue and also something I haven't heard of any other app/browser doing?

Chrome is slowed down heavily just by 10 notification updates per seconds, even if they do not occupy as much RAM, so I think limiting the notification updates would be the best to prevent chrome from crashing.

Could be similar, but this time it's Android who didn't GC the memory properly

It is actually limited to 4096 but we can sanitize a second time. Also I don't think long title is the real cause, it should be related to GC'ing RemoteViews.

I think ideally this should be fixed by the Android framework, but throttling on our side makes sense as it also reduces the UI jankiness. Updating the notification in such a frequency already makes the System UI unusable.

Also, when the notification is updated so frequently, the media buttons is unclickable on some Android versions

[Media>UI] Apply throttling if the notification is updated too frequently

There's a issue where the notification is updated too frequently
(especially when the media metadata or fallback media metadata changes),
which can cause the system UI to be very janky or even a system crash.
This CL throttles the notification update if the notification has been
updated during the previous 500ms.
