- In some places, we weren't nulling out references to destroyed objects. This
fixes that.
- (These were all discovered via LeakCanary instrumentation, and the fixes are
hopefully rather straightforward-looking.)
- When the `viewHolder.messageBody` `TextView` created by a `MessageAdapter` is
set to selectable, it leaks an `android.widget.Editor` (because that editor
registers a view observer that never gets unregistered).
- This memory leak is really quite problematic, as the message adapter is used
a lot!
- Having the text be selectable is useless anyway, though; there isn't any way
to select it (because long pressing just opens the context menu anyway).
- It looks like the ListSelectionManager was meant to track selections across
multiple messages. However, I'm not sure this feature ever gets used.
- Accordingly, this commit removes the entire feature, thus fixing the memory
leak (since no `Editor` objects are ever created).
- It should also reduce memory usage in general, since we aren't attaching an
`Editor` to every single textview we create.
- A `TextView` only allocates an `Editor` if you ask it to do certain things,
like make the text selectable or register custom selection callbacks.
we don’t want 'manage accounts' and 'settings' to show up when within a conversation.
we also move out disable notifications and add to favorites into an overflow overflow
to make the menu shorter (after adding 'Search messages' it became very crowded)
Currently Conversations lacks any keyboard shortcut to send a message if enter_is_send is disabled.
KeyboardListener has been extended to include the original KeyEvent as an argument.
fixes#3829
on some phones the onBackendConnected finishes prior to the onActivityResult()
leading to the pending photo uri being cleared before processing the result.
this leads to 'Take photo' not working.
but we probably don’t need to clear the photo uri if there is to activiyResult
to clear as well
