I am building an app where there is a person is speaking, kinda like a podcast, and I would like the listener to be able to listen when the screen is off.
I am using Flutter, and the media player is complete, but if i turn the phone screen off, the media stops.
I have no idea how to treat this so when you turn off the screen, the media will still play.
You need to use a background services plugin. I recommend the audio_services plugin available here: https://pub.dev/packages/audio_service#-installing-tab-

I'd like to develop a music visualizer app for tvOS which has the ability to listen to whatever background audio is playing (like Spotify, Pandora, etc.). Does anyone know if this is even possible on iOS/tvOS? In other words, there would have to be some functionality that allows the system audio output to be treated like an audio input.
I imagine that it would be the same functionality as doing a screen recording capture, at least the audio part.
My goal is to be able to do this programatically (Objective-C) so that the user doesn't have to do anything, it just "works" out of the box, so to speak.
Thanks
I'm trying to develop an app which shows lockscreen media controls (MPRemoteCommandCenter and MPNowPlayingInfoCenter).
The tricky part is that I'm not playing a media on the phone but on a remote server (like Google cast).
I managed to do it by playing a silent audio file on the phone which shows the lockscreen controls but it doesn't feel like a good solution (unnecessary battery drain).
Is it possible to show these controls without playing anything on the phone ?
I'm trying to create a web radio application. For now, I'm able to play music from a streaming web radio, even when my application is on background (thanks to Background modes and the AVAudioSession singleton) I would like to know if I would be able, with the AVAudioPlayer class I'm using, to use the device music player to stream my web radio on the device locked screen and control it (see the screenshot I provided as an example) .
Thanks for reading me,

I found an issue to my problem. All I had to do is to use the MPNowPlayingInfoCenter class and to set informations like the song title. The audio controls show themselves automatically when you play sound thanks to the AVAudioSession singleton.
I'm trying to create an HTML5 video player to automatically start streaming video. I searched a lot but I didn't achieve my goal.
Then I found www.filmon.com, where all videos start to play automatically on iPad.
Does anyone know how they did it? I looked at their JS files, but I cannot make mine start automatically.
Apple has specifically disabled every method and workaround to autoplay video on iPads and iPhones (the "autoplay" attribute, and Javascript solutions like triggering hidden link's "onclick" event).
I have yet to find a way to autoplay on iPads and it looks like Apple is continuing to squash all efforts to do it. They state, "In Safari on iPhone OS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, autobuffering and autoplay are disabled. No data is loaded until the user initiates it."
As a quick update I just checked out Filmon.com and the videos there no longer seem to be autoplaying on an iPad. Example: http://demand.filmon.com/distant-roads-173-cnd-ontario-ca-1 autoplays on Chrome, but not on the iPad.
I don't think that iphone or ipad play streams automatically due to high traffic.
Why don't you play it manually using script at document ready?
somewhat like this:
window.onload=function(){
var audio = document.getElementById('audio');
audio.play();
}
I am writing a web app that uses HTML5 audio. I want to make sure that the user can move to a different application while still listening to the audio in the background. This works while the web app is still within Safari itself. However, when the user adds the web app to their homescreen and it has been set to allow for fullscreen access (no Safari toolbars), when they leave the app the audio does not continue to play. Does anyone know of any way to have a web app proceed while in the background?
Thanks.
I observe exactly the same thing. It's really puzzling as to why Safari, webkit on iOS I suppose really, handles it differently in the two cases.
I notice one thing that might be a small clue, when running as a home-screen'ed 'app' when you playback the audio the iOS status bar (at least on my ios4.1/iphone4) does NOT show playback indicator (blue triangle). But when using the site directly via Safari (and the sound stays in the backgroun as expected) it DOES show the playback indicator.
I think the only people who can probably answer your question are apple since it's their webkit implementation. If you haven't already I would urge you to take this up on the apple developer message boards.
For others not familiar the 'full screen access' Dan is referring to is a Safari specific meta tag that enables a bookmarked web page to open in safari 'full screen' without the location and menu bars.
While HTML5 is making progress on supporting device native features through HTML 5 APIs (such as accelerometers, etc) having true background audio seems like it hasn't really been spec'ed out yet. By background I mean when the browser is not the application that the user is currently focused on. It was only more recently that iOS even supported application multitasking which is what making the behavior from safari possible but it's a separate thing together to integrate that tightly with the OS'es native audio control features, which is what would need to happen.
This is not possible, at least not currently. You are playing the audio from the browser and when the browser closes the system kills the app, or freezes it, unless it has multi-tasking support(but that isn't allowed for web apps)
In iOS 5 and Android 4.0.3, putting a browser window to background does not stop playback. I am not sure about other versions prior to them.
You can do so with an iPhone 4. On my website, I posted a song with the simple html5 tag and I went on it with the iPhone 4. Played the song, left the app. Song runs in the background and there is even a play button on the top bar like when you listen to music on the iPod app.
