message list allows multiple messages
being copied to clipboard at the same time;
if these messages as not just text, a summary is added,
sth. as "Voice Messages" or "Forwarded: Image - this is my family" etc.
this is on purpose and the gist of the action,
renaming the action to 'Copy Text' makes that more clear.
* 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 UI does not check before selection if a message can be resent,
this is subject to change and not worth the effort.
instead, just an error is shown.
for the ID_NEVER_SHOW_AS_ACTION_* - this is a bit ugly,
however, the few alternatives i tried were even more uglier,
Java and Array-primitives are just not great.
as it is not changed often, it is probably not worth the effort to dive deeper.
in the long-tap context menu, on smaller screens,
functions go to the overflow menu from right to left.
this pr gives the "delete" a higher priority than the
only sometimes available "export" function
- delete is always available on smaller screen -
before, the icon was sometimes there and sometimes not,
which is a bit irritating
- export gets a similar priority as copy
- on/off icons are now functions that are used
less frequently
