- Eliminate the explicit spongycastle dependency. All access to
primitives is done through the JCE interfaces now, which allows
us to use a secure native-backed provider like conscrypt.
- Use conscrypt for our default security provider. This gives us
fast TLS 1.2 and 1.3 support on all devices, even before they
had platform support (like 4.4).
- Update minSdk to 18. Unfortunately the JCE interfaces for GCM
primitives are JDK 7+ (!) only, which became supported by Android
at 18.
Update our media send flow to allow users to send multiple images/videos
at once. This change includes:
- New in-app media picker flow.
- Ability to caption images and videos.
- Image editing tools are made more prominent in the flow.
- Some fixes to the image editing tools.
This is to guard against behavior WorkManager has where it may
re-enqueue a job that has already been completed (if, for instance, it
was preempted).
Fixes#8268
Because SMS sending is split over two jobs, there's no max retry limit
respected if we find out about the failure in SmsSentJob -- it's
requeued as a new job with a fresh attempt counter.
This commit carries a retry count between the two jobs. It also verifies
that we have service before attempting to send a message at all.
Relates to #8268
Due to an Android P bug, we basically need to stop calling
startService() in onResume()/onPause(). That means I had to turn
MessageRetrieval service into a singlton instead of a service. I also
moved the offending KeyCachingService calls into static methods that
didn't have to start the service.
Occasionally a job may be run when the app is in a network-restricted
mode, like a form of doze. When this happens, jobs can timeout due to
lack of network access, causing a cascade of job delays. This is
particularly bad in the case of message retrieval.
To prevent this, if a job that normally requires network detects that no
network is available when running, then we start a foreground
notification.
Keep the single-use behavior, but allow the creation of multi-use memory
blobs that can be deleted when we're done with them. Will help out with
having URI's for temporary images during the camera capture flow.
This also fixes the situation where we block group-leave messages,
preventing blocked contacts from leaving groups.
Fixes#7970
Also, this forced us to upgrade libsignal-service, which fixes the
websocket timeout issues. Thanks to @dpapavas!
Fixes#6644
