Why Does Agora.io v4 web sdk have an echo? - agora.io

I just installed the v4 web sdk, and when run the meeting i hear an echo. Its not an issue when i use headphones, which is okay. But when i dint use one, i hear an echo which is persistent. I have used other platforms like Google, Zoom, Web-ex, Blue jeans. etc. But I never had this issue. What am i doing wrong?
I looked into the Agora FAQ, but that was not helpful. I have contacted support, but haven't heard anything yet other than the headphone use.
I have tried everything in this section - https://docs.agora.io/en/All/faq/audio_noaudio
Best,
Vig

To remove noise/echo you can use these properties AEC, ANS. It helps you in improving audio.
await AgoraRTC.createMicrophoneAudioTrack({
AEC: true, ANS: true
});

Android - All users have to install Google Play Services?

For devleopment I have to do this:
If not installed yet, you have to install the following packages :
Extras / Google Play services
Extras / Google Repository
Android 6.0 (API 23) / Google APIs Intel x86 Atom System Image Rev. 19
Android SDK Build-tools 23.0.3
Is this for development only? Or do all my users of the app have to also download Google Play Services etc?
Yes I know this isn't really a question for stackoverflow, but where else can I ask this question? They are not letting me ask this in the github issues either.
I also can't test this, because react-native-maps isn't working for me, it keeps crashing. I wash hoping to learn if its worth the effort to fix the crash. If users have to install a bunch of stuff to use this, then its not worth.
If you are using services provided by Google Play Services like Maps, or push messages, location services or in-app payments then yes, your users must have it installed too. If you are not using Google Play Services, then it's not required.
But if required, they have to install Google Play Services app from Play Store, not development stuff like you listed:
https://play.google.com/store/apps/details?id=com.google.android.gms&hl=en
EDIT
How come Google doesnt defalt install this?
Google Play Services or apps like Calendar, GMail etc are NOT part of Android. These are Google applications and may or may not come preinstalled, depending on licenses phone/tablet manufacturer purchased from Google. As Android can perfectly live w/o these apps, some devices does not include it or come with alternatives (i.e. using other providers than Google).
I don't know even know where the proper place to tell them would be
Your app should check if Google Play Services exists usually on start before it start using it. See this documentation which discuss this.
Weird, I just clicked on "Google Maps" on my Android Simulator and it made my react-native-maps start working.
There was a licence agreement when I clicked Google Maps on the phone, so as soon as I accepted it, react-native-maps started working.

Symbian S60v3 3rd Edition FP2 SDK Emulator Unlock

I've been playing around with the SDKs of Symbian OS and I've encountered an issue that I couldn't bypass.
Specifically I've been using S60v3 3rd Edition Feature Pack 2 SDK's Emulator.
I want to test some .sis/.sisx application and maybe develop/fix some of them (also nostalgia from some old games that I used to play that can no longer be emulated any other way).
The issue is that all the application that I want to install on the emulator have the signature error, and since it's no longer possible to sign them I tried using one of those apps (HelloOX v2) that will remove the signature check.
Sadly those don't seem to work at all on the Emulator for some reason. Even though I checked the options in application settings to accept all software installation and disabled certificate check.
Is there a way to somehow unlock/hack the emulated OS from the SDKs?
I know this is dead technology which makes it even harder to find a solution for this.
Thanks in advance for your help if someone actually knows.

How to detect a docked device in cocoa

I've been searching all over the web and have found solutions to mounted device detection from within a Cocoa App using the NSWorkspace notification system. However this notification doesn't seem to be triggered when an Apple device is docked.
I specifically want my OSX App to detect docked iPads/iPhones, be able asses whether the iOS version of my App is installed and then synchronise files. I realise that the easiest way to do this is using iCloud, but I do not as yet have a developer membership with Apple and would like the option to be able to synchronise files without the internet.
An iTunes like system would be ideal. Any ideas.
Thanks in advance.
Apple don't provide any official APIs for doing what you ask.
Unofficially, you can try the stuff here: https://bitbucket.org/tristero/ipodaccessframework
You can definitely use it to determine whether a particular app is installed (by looking for a match for its bundle-id) and you can read/write files to/fro a particular apps document directory.
Disclaimer: this one is mine. There are definitely other libraries around that achieve similar results.

Does Titanium have method for "didReceiveRemoteNotification" of Objective-C?

I would like to receive remote push notification when the app is on the foreground. I think I can use "didReceiveRemoteNotification" in Objective-C, but how about in Titanium? I've been searching solutions but can't find anything. Does anybody help me out?
Titanium currently only supports local notifications (by default) I believe. You might want to take a look at AppCelerator as a solution.
Sorry, i was wrong last time. It's very hard to find but Titanium supports a way of interacting with PushNotifications.
Please take a look at Ti.Network.registerForPushNotifications. It provides a callback that is executed when you receive a Push Notification.
The other posted solutions below may provide a better integration for titanium so it's up to you what you want to use. But this should answer your original question.
Unfortunately Titanium only supports local notifications on iOS. If
you want to support remote notifications you can use
Urban Airship
ACS (Appcelerator Cloud Services) or
you write your own module that provides "didReceiveRemoteNotifcation" as an app event to your app
As far as i know you can only listen on local notifications by
default but you can try this method if it reacts on remote
notifications..

Safari can't get HEROKU's cookie

I am sorry that I am not able to provide much info because I totally have no idea about this weird problem.
I have a fb canvas app which is written by rails 3.2.2 .
There is not any problem on my local machine (Mac OS X 10.7.4).
When I deploy it to heroku, it is fine with chrome and firefox. However, when I use Safari to browse it, Safari can't get any cookie from heroku. (it shows "This site has no cookies" in developer tool, but it works well on my local machine.)
I have googled this problem, and I get something like this and this, but I don't think these are the case of mine.
any suggestion?
If you need any specific info about my code to solve this problem, please let me know.
I will appreciate it very very much!!
I finally found out that it's a problem of safari's security setting.
As fb canvas gets heroku's content through iframe, there may be security issues. If we donwgrade the 'Block cookies' of safari's privacy settings from 'From third parties and advertisers'(default) to 'Never', everything works well!
However, I don't think asking users to downgrade their security settings is a good idea. I am wondering whether there is a solution to avoid this restriction in safari.
please let me know if you have any idea. many thanks :)
