AudioStreaming | Cross platform audio streaming library | Audio Utils library

volume is a property on SPTAudioStreamingController object, so to get the current volume you simply need to get a reference to your SPTAudioStreamingController and then read the volume off of that.

Then, to reset the volume, you can use SPTAudioStreamingController's setVolume:callback: function.

And if it works, I suspect that second delegate method you pointed to in your question will fire, but you can also use the callback to detect whether an error happened.

The formatting of the code makes it challenging to see what's going on, but it looks like the function audioStreamingDidLogin(:SPTAudioStreamingController!) is not a class function. Maybe global, because it's declared outside the class where self is available.

You may be able to:

• move it into the class
• pass some instance of ViewController into the method as a parameter

Moving it into the class makes most sense to me.

Edit: Fix code

I am also using libusb library to record from USB microphone on Android.

I was trying to use libusb interface to parse descriptors by for example libusb_get_config_descriptor() but unfortunately it didn't work.

My solution was to do it by myself. Using USB documentation + getRawDescriptors() method in UsbDeviceConnection class:

I'm not sure that this is your entire problem, but I see that you are calling media player.prepare() in the doInBackground method of your AsyncTask, and then calling media player.start() in onPostExecute(),

But you haven't waited for the player to finish initializing after the call to prepare(). You need to use an OnPreparedListener, and wait for that notification before interacting with the player.

UIApplicationDelegate method application:didFinishLaunchingWithOptions: is called first, followed by application:openURL:options:.

That first app delegate method sets self as the delegate for an AudioStreamingController. This is how audioStreamingDidLogin gets called. You're telling the streaming controller, "Tell me (self) when interesting things happen". (See the SPTAudioStreamingControllerDelegate docs for what else it might tell you about).

You probably wouldn't (shouldn't) call this function directly, especially if there's a chance that you might call it before auth is complete. Doing so would likely result in an error on the call to playSpotifyURI. If you're certain that the user is authenticated, then you don't need to call it. Just call what it calls: playSpotifyURI.

it is because apple is not allowing you to load any http contents by default. if you looks closely on debug console you might have got this below error

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

To solve it just add below to your info.plist file

Well there are two things I am seeing here:

Ok, so it has to do with the silent mode switch being on silent. I have never encountered this issue before. Does anyone know if this is a new thing?

I had to add this:
