Stricter synchronization by always using the same "loadedSearchEngines"
variable.
With "loadedSearchEngines" calling "refreshAsync()" we also get the fallback
engines to contain reddit and youtube (which are programatically added) and
also now we properly remember and display the engines added by user.
We have two search engine types:
- one based on MLS reported region,
- one based only on Locale.
There are multiple steps involved in returning the default search engine for
example and though at each step we could verify if a certain operation is
completed we are still exposed to concurrency issues.
Simplest and most effective way to make sure the MLS engines do not mix with
Locale based engines is to use the same type of engines for the entire duration
of the app. At the next cold start we'll verify again which engines to use.
Using the Locale based engines (fallbacks) is expected to only happen once, at
the first run of the application after being installed.
This is functionally equivalent to the code before this patch but should
be slightly more performant in theory because ConstraintLayout is
expensive to inflate.
The elevation and layoutParams set dynamically appeared to have no effect
with the wrapping view but broke the view when used by itself so I had
to remove them. I also updated a few other unnecessary params.
Theoretically this may have some perf benefits but I didn't see anything
outside noise levels after I took the numbers (but I didn't try very
hard).
* for #11830 added new metric for collecting startup method
move all source startup telemetry into its own logic and added an UNKOWN state
* switched back to onNewIntent solution
* renamed the metric
When you remove a search engine from our list, an undo snackbar that outlives the fragment is shown. If you go back to the search fragment and press undo, now the shortcut list gets updated
The observer was moved and is now bound to the activity and its
context. If the activity is re-created we leak the observer and
therefore the activity itself.
With this we make sure to stop the observer and also don't use
the activity context to begin with.
