* reword "Webxdc [content]" to "Webxdc Apps"
adding "App" to the term makes things much clearer to the user,
was "Webxdc" is about.
eg. on iOS, we have an app selector meanwhile,
calling that _just_ "Webxdc" in the menu or in the title makes it pretty
unclear to the user what this is about.
same for the tab "Webxdc" on desktop or the default description in the summary.
otoh, calling it _only_ "Apps" (as now), may also raise false expectations
and may be mixed with "normal" apps.
so, "Webxdc App" seems to be a good approach.
there is also the term "Mini App" [^1], we could also go for that,
but this is a broader discussion as this would give up the term "Webxdc" partly.
in any case, if there is few space in the UI,
it seems to be okay to abbreviate with just "App" or "Apps" as needed,
if it is otherwise clear that the thing is a "Webxdc App" or "Mini App".
[^1]: the term "Mini App" is aleady known for similar types of apps
(some "small app" running in a "super app")
cmp. https://www.w3.org/TR/mini-app-white-paper/#what-is-miniapp .
of course, our "Webxdc Apps" are not compatible with other "Mini Apps"
however, this is also not the case between "Mini Apps" of other vendors
which also have different focuses.
so "Mini App" seems to be a broader term and does not imply compatibiliy.
* use term 'Private Apps' for webxdc content
* add some translator hints
* do not set deprecated stock-translations
* mark now unused stock translations as deprecated
* add new system messages to english strings.xml
* add translator comments to new strings
* set new system messages
* simplify contact list
this also disables "fast scrolling" for the contact list;
the "fast scrolling" code is too much bound to the bubbles and a-z
to be preserved without much effort.
however, "fast scrolling" seems to be much less important
with a list sorted by "last seen".
there is also the rough idea to raise minimal-origin of contact list,
this would make the list much smaller
(<https://github.com/deltachat/deltachat-core-rust/pull/2411>),
otoh, not sure if #2411 is a thing for list sorted by "last seen".
also the other lists (chatlist, archive, blocked) may become quite huge as well
and do never have "fast scrolling".
in case it is really needed again,
however, we should go for the implementation available in RecyclerView since some time:
<https://stackoverflow.com/questions/45370246/how-to-use-fastscrollenabled-in-recyclerview>
* less padding as the A-Z decorations do not longer need space
* remove unused contact_selection_recyclerview_header
* add 'Add to Home Screen' menus for webxdc apps
* make adding shortcut basically work
* avoid starting webxdc from foreign accounts
* recreate back stack, if possible
according to
https://developer.android.com/training/notify-user/navigation :
"When you start an activity from a notification,
you must preserve the user's expected navigation experience.
Tapping Back should take the user
back through the app's normal work flow to the Home screen [...]"
same seems to be true for shortcuts using the same class for constructing
the back stack.
the back stack is reconstructed for API 26 (Oreo, 2017) or newer,
for oder API `requestPinShortcut()`
only uses the top-level activity for the shortcut.
working around that is probably possible, but would be quite some effort in an
already complicated area and would result in bugs that are not so easy to see.
also, on these old androids, users are probably used to the no-back-stack
behaviour.
* show a warning if app was deleted
* add 'Add to Home Screen' also to gallery
beside chat- and webxdc-activity,
this is the third place where the webxdc is listed.
as adding may result in dialogs from the launcher,
we allow the option only for a single selected webxdc,
as otherwise a series of dialogs would pop up.
* show 'Done' toast short, this is what we are doing at all the other places when showing 'Done'
the spacing was just a bit too much,
eg. bubble spacing is 6dp atop and abottom.
this was always not-so-good, however, as info-messages are
more in use by webxdc now, it gets more visible.
the new spacing roughly matches the layout on ios.
