As Google Cast SDK calls GCKSessionManager.suspendSessionWithReason
when the app goes to background, one solution is to replace this method with a different implementation that checks if the reason is .AppBackgrounded
and then actually ignores the call.
Then SDK doesn't kill the the session immediately when app goes to background but it will still suspend the session at a later point. The session can however be restarted from background mode – it however takes significant time and that delay is negatively perceived from the user perspective. Furthermore the session regularly suspends again after a few seconds of not "talking to it".
Any better solution is still very much appreciated.
extension GCKSessionManager {
static func ignoreAppBackgroundModeChange() {
let oldMethod = class_getInstanceMethod(GCKSessionManager.self, #selector(GCKSessionManager.suspendSessionWithReason))
let newMethod = class_getInstanceMethod(GCKSessionManager.self, #selector(GCKSessionManager.suspendSessionWithReasonIgnoringAppBackgrounded))
method_exchangeImplementations(oldMethod, newMethod)
}
func suspendSessionWithReasonIgnoringAppBackgrounded(reason: GCKConnectionSuspendReason) -> Bool {
guard reason != .AppBackgrounded else { return false }
return suspendSessionWithReason(reason)
}
}
All we need to do now is to call GCKSessionManager.ignoreAppBackgroundModeChange()
.
Edit:
As of latest Google Cast SDK, it has a new option to keep sessions alive in background.
