This only works automatically on Android >= 8. On other platforms / versions, it
relies on the SDK user on implementing a "reduced UI" mode and reacting to the
"request PIP" delegate method.
Story time. Currently the app can be started in 4 ways:
- just tapping on the icon
- via a deep link
- via a universal link
- via the phone's recent calls list
The last 3 options will make the app join the specified room upon launch. React
Native's Linking module implements the necessary bits to handle deep or
universal linking, but CallKit is out of its scope.
In order to blend any type of app startup mode, a new LaunchOptions module (iOS
only) exports a getInitialURL function, akin to the one in the Linking module,
but taking CallKit instents into consideration. This function is then used to
make app startup with a URL consistent across all different modes.
Due to the difference in nature, the iOS and Android implementations are
completely different:
iOS: MPVolumeView is used, which allows us to place a button which will launch a
native route picker provided by iOS itself. This view is different depending on
the iOS version, with the iOS 11 version being more complete.
Android: A completely custom component is used, which displays a bottom sheet
with the device categories, not devices individually. This is akin to the sheet
in the builtin dialer.
Revert "[RN] Remove unnecessary source code" (commit
a3441030a3). But since the project file
needs to explicitly mention the CallKit and Intents framework, do not
use the semantic @import as that's confusing in the case.
* Javadoc introduced @code as a replacement of <code> and <tt> which is
better aligned with other javadoc tags such as @link. Use it in the
Java source code. If we switch to Kotlin, then we'll definitely use
Markdown.
* There are more uses of @code in the JavaScript source code than <tt>
so use @code for the sake of consistency. Eventually, I'd rather we
switch to Markdown because it's easier on my eyes.
* Xcode is plain confused by @code and @link. The Internet says that
Xcode supports the backquote character to denote the beginning and end
of a string of characters which should be formatted for display as
code but it doesn't work for me. <tt> is not rendered at all. So use
the backquote which is rendered itself. Hopefully, if we switch to
Markdown, then it'll be common between JavaScript and Objective-C
source code.
This commit adds initial support for CallKit on supported platforms: iOS >= 10.
Since the call flow in Jitsi Meet is basically making outgoing calls, only
outgoing call support is currently handled via CallKit.
Features:
- "Green bar" when in a call.
- Native CallKit view when tapping on the call label on the lock screen.
- Support for audio muting from the native CallKit view.
- Support for recent calls (audio-only calls logged as Audio calls, others show
as Video calls).
- Call display name is room name.
- Graceful downgrade on systems without CallKit support.
Limitations:
- Native CallKit view cannot be shown for audio-only calls (this is a CallKit
limitaion).
- The video button in the CallKit view will start a new video call to the same
room, and terminate the previous one.
- No support for call hold.
The error is stored in the redux store in base/config so other components can
consult it. It is also broadcasted as a new event in the external API for the
SDK.
JitsiMeetViewListener currently has methods of one and the same pattern
so adding new methods i.e. events i.e. redux action types is a question
of repetition in the Java source code. Speed up the support of new
events by trying to deal with them in a generic way.
The same goes for JitsiMeetViewDelegate.
Deep/universal linking now utilizes loadURL (when possible). But loadURL
is imperative in the native source code while its JavaScript counterpart
i.e. React App Component prop url is declarative. So there's the
following bug: open a URL, leave the conference (by tapping the hangup
button, for example), and then opening the same URL actually leaves you
on the Welcome page (if enabled; otherwise, a black screen).
The implementation has a flow though: opening the same URL twice in a
row without an intervening leave will leave the first opening and join
the new opening. Which can be improved by not leaving and joining if the
conference is joined, joining, an not leaving. But that can be done
separately as an improvement independent of the current implementation
details.
Introduces loadURLObject in JitsiMeetView on Android and iOS which
accepts a Bundle and NSDictionary, respectively, similar in structure to
the JS object accepted by the constructor of Web's ExternalAPI. At this
time, only the property url of the bundle/dictionary is supported.
However, it allows the public API of loadURLObject to be consumed. The
property url will be made optional in the future and other properties
will be supported from which a URL will be constructed.
Initializing a new URL/NSURL instance is a chore especially when one
takes into account that the JavaScript side (1) is loading the URL
asynchronously and (2) is capable of parsing strings that may or may not
be represented as URL/NSURL.
The Android method loadURLString(String) may have been called
loadURL(String) to overload loadURL(URL) but I didn't want to do that
because:
1. It would not be compatible with existing source code such as
loadURL(null) which would have become ambiguous.
2. I wanted to achieve better convergence with the iOS API.
On iOS, if the app is closed the startup options are only passed as the
`launchOptions` dictionary of `applicationDidFinishLaunching`. Thus add a helper
method to be called from there by embedding applications so we can copy that
dictionary.
