Seems to not be possible to do currently in aliendalvik at least not graphically. Maybe there is some config file to do that but I don't know which one.
Update: Version 3.31.4 is out now. This version is now based on the Signal code base as LibreSignal is no more.
Signal now supports WebSockets so it is usable fully without GCM (PlayServices).
So this version introduces several new features:
GIF Support
Voice Messages
Call support should work (though it might not ring on incoming calls)
Attachments now shows the image gallery with images to quickly use as attachment
QuickScroll Up/Down Feature
Overlay showing the Date of chat messages when scrolling up
Timed Messages (Selftimer that destroys message after read and given delay)
Hint showing unread messages in chat window
Video support
Support for website distribution build with auto-updating APK (though this will rename the app from LibreSignal to Signal and won't ship timebomb removal and other patches)
New Base Signal 3.31.4
This new version requires you to reregister after upgrade. Chats and History will be saved on upgrade but it will not allow you to send Signal Messages before reregistering. Reregistering works only by phone so SMS step will be skipped (with the usual error message)
Of course this version comes with the usual Patches for SailfishOS & BlackBerry to skip SMS registration (as it is non working on Android Runtimes) and has the 90 day timebomb removed.
I installed on my Blackberry. Sorry for the likely lame question, but why does the app call itself LibreSignal instead of TextSecure as this thread calls it?
can this be used on tablet without phone number? What about multi device support?
Would be wery niiicecto se a link to general description of these signal / trxt secure features.
Totally fed up to releses like " this is a client/ host to xyz service implementing only subset of features fgh of this but also supports wqrt server but only..."
It needs a phone number. You can register your tablet with one phone number.(So you need a phone for the activation number)
However only one phone number per device. (Exception for the Signal WebApp for Chromium which you can pair with your phone/tablet)
Thanks for your work, it's good to see they've finally grown brains and made their application truly trustworthy. Now hopefully they will adopt a looser position on third party clients so for example Whisperfish will be allowed to continue existing.
