In the Android SDK, the setServerURL option is erroneously
ignored. The meeting's serverURL always defaults to
https://meet.jit.si because the serverURL is not parceled.
It's the source of uncountable problems for which we don't have a good
solution, since they are caused by buggy implementations of self-managed
connection services by manufacturers.
In 49e3b03885 we turned on SW encoders / decoders
on account of some devices having broken HW *encoders* and also our desire for
using simulcast.
Well, the astute reader may have noticed that only *encoding* was mentioned.
Indeed, we should be able to keep using the HW decoder just fine.
This shouldn't be needed, as ConnectionService should take care of it, but we
suspect some devices don't do it since we got reports of people not hearing
users, and the problem went away when CS was disabled.
Fallback to the non-ConnectionService case for any error. Also, handle errors
when registering the phone account; Pixel C devices throw UnsupportedException.
Some Samsung devices will fail to fully engage ConnectionService if no SIM card
was ever installed on the device. We could check for it, but it would require
the CALL_PHONE permission, which is not something we want to do, so fallback to
not using ConnectionService.
Some devices seem to have a bug in their Android versions and startCall fails
with SecurityError because the CALL_PHONE permissions is not granted. This is
not a requirement for self-managed connection services as per the official
documentation though:
https://developer.android.com/guide/topics/connectivity/telecom/selfManaged
Alas, connection services takes over audio device management too, so let's
handle the error and disable CS if we get SecurityError.
Samsung devices (of course) seem to stick with the earpiece if we first select
Bluetooth but then set speaker to false. Reverse the order to make everyone
happy.
This only applies to the generic and legacy handlers.
When ConnectionService is used (the default) we were attaching the handlers too
early, and since attaching them requires that the RNConnectionService module is
loaded, it silently failed. Instead, use the initialize() method, which gets
called after all the Catalyst (aka native) modules have been loaded.
Separate each implementation (3 as of this writing) into each own "handler"
class.
This should make the code easier to understand, maintain and extend.
We are downloading code off the Internet and executing it on the user's device,
so run it sandboxed to avoid potential bad actors.
Since it's impossible to eval() safely in JS and React Native doesn't offer
something akin to Node's vm module, here we are rolling our own.
On Android it uses the Duktape JavaScript engine and on iOS the builtin
JavaScriptCore engine. The extra JS engine is *only* used for evaluating the
downloaded code and returning a JSON string which is then passed back to RN.
