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.
Android Studio won't build the app otherwise. Since the gradle plugin 3.0 beta7,
the minimum supported build tools version is 26.0.2, so set it to that. Also
bump compileSdkVersion to 26 since they need to match (in the major number, that
is).
The target API is still 25. Android Oreo (26) brought some changes in overlay
permissions which I haven't figured out yet.
* 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.
* Regardless of whether the SDK client/consumer employs
JitsiMeetActivity or JitsiMeetView, default to finishing the
associated Activity upon invoking the back button (which is what
Activity#onBackPressed() is documented to do).
* Do not break the public API of JitsiMeetView and, thus, Jitsi Meet SDK
for Android.
Don't require autofocus because that prevents the app from appearing in
Google Play Store for some devices.
Don't require camera for the same reason but also because camera/video
is not a mandatory feature of the app, it's merely likely very
desirable.
[RN] Increase the coverage of JitsiMeetViewListener
JitsiMeetViewListener is an integral part of the public API of Jitsi
Meet SDK for Android. Utilize it in the Debug configuration of the Jitsi
Meet app for Android in order to increase (1) awareness of API breakages
and (2) API coverage.
The same goes for JitsiMeetViewDelegate in Jitsi Meet SDK and app for
iOS.
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.
[Android] Don't mute the microphone under any circumstance
It's a global action, and if we do that other applications won't be able to use
it. I experienced this with the system camera. We do, however, make sure to
enable it when we need to.
Note that enabling it doesn't mean we are *using* it. It just means we *can*,
and that we will get actual audio when we do.
[RN] Cache avatars and provide a default in case load fails
Avatars are cached to the filesystem and loaded from there when requested again.
The cache is cleaned after a conference ends and on application startup
(defensive move).
In addition, implement a fully local avatar system, which is used as a fallback
when loading a remote avatar fails. It can also be forced using a prop.
The fully local avatars use a user icon as a mask and apply a background color
qhich is picked by hashing the URI passed to the avatar. If no URI is passed a
random color is chosen.
A grace period of 1 second is also implemented so a default local avatar will be
rendered if an Avatar component is mounted but has no URI. If a URI is specified
later on, it will be loaded and displayed. In case loading the remote avatar
fails, the locally generated one will be used.
[Android] Fix resource leak when JitsiMeetView is destroyed
In iOS this is automagically done in the view destructor, bunt we don't have
that luxury in Java we have to do it manually.
The new disponse() method MUST be called when the Activity holding the view is
going to be destroyed, typically in the onDestroy() handler.
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.
This was already an implicit requirement, as it's the only version implemented
in libwebrtc.
The reason to add this is to (defensively) try to filter old devices which may
not implement it.
WebRTC's own Android demo app defines this.
