The Audio interface allows to set its volume, but apps usually use the Media or Notifications volumes on Android. In a Gluon Mobile app, pressing the volume keys does nothing, while in other apps the device's volume changes.
Tested on Android 8 and 12 using Attach version 4.0.15.
Is there a way to play audio using the device's volume settings and allow the user to adjust the volume from within the device?
There seems to be no proper way to do this. Using the VideoService it's possible to change the volume of the device, but only while audio is playing, which requires the user to be ready to do so for short audio clips.
The VideoService also does not support playing a single file out of a playlist. The only solution I found was switching the playlist to a single audio clip whenever it's required to be played and isn't played already:
class MobileNotifier {
private static final String SMALL_BEEP_PATH = "/sounds/SmallBeep.wav";
private static final String BIG_BEEP_PATH = "/sounds/BigBeep.wav";
VideoService service;
private MobileNotifier(VideoService service) {
this.service = service;
service.getPlaylist().add(SHORT_BEEP_PATH);
}
public void play(Alert alert) {
switch (alert) {
case SMALL -> {
if (service.statusProperty().get() != Status.PLAYING || !SMALL_BEEP_PATH.equals(service.getPlaylist().get(0))) {
service.stop();
service.getPlaylist().set(0, SMALL_BEEP_PATH);
service.play();
}
}
case BIG -> {
if (service.statusProperty().get() != Status.PLAYING || !BIG_BEEP_PATH.equals(service.getPlaylist().get(0))) {
service.stop();
service.getPlaylist().set(0, LONG_BEEP_PATH);
service.play();
}
}
};
}
}

I'm looking to do a very simple piece of code that plays a sound effect. So far I have this code:
SoundManager snd;
int combo;
private void soundSetup() {
// Create an instance of the sound manger
snd = new SoundManager(getApplicationContext());
// Set volume rocker mode to media volume
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
// Load the samples from res/raw
combo = snd.load(R.raw.combo);
}
private void playSound() {
soundSetup();
snd.play(combo);
}
However, for some reason when I use the playSound() method, nothing happens. The audio file is in the correct location.
Is there a specific reason you are using SoundManager? I would use MediaPlayer instead, here is a link to the Android Docs
http://developer.android.com/reference/android/media/MediaPlayer.html
then it's as simple as
MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.combo);
mp.start();
Make a directory called "raw/" under the "res/" directory. Drag wav or mp3 files into the raw/ directory. Play them from anywhere as above.
i have also attempted using the top answer, yet it resulted in NullPointerExceptions from the MediaPlayer when i tried playing a sound many times in a row, so I extended the code a bit.
FXPlayer is my global MediaPlayer.
public void playSound(int _id)
{
if(FXPlayer != null)
{
FXPlayer.stop();
FXPlayer.release();
}
FXPlayer = MediaPlayer.create(this, _id);
if(FXPlayer != null)
FXPlayer.start();
}
I developed a simple application to turn ON/OFF flashlight. But I couldn't find a way to turn on front flashlight of a device(if available).
Code for availability check :
boolean hasCameraFlash = getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH);
My code for turn ON is :
#RequiresApi(api = Build.VERSION_CODES.M)
private void flashLightOn() {
try {
String cameraId = cameraManager.getCameraIdList()[0];
cameraManager.setTorchMode(cameraId, true);
} catch (CameraAccessException ignored) {
}
}
Is it possible to turn on front flashlight of device without turning on camera.
Any help will be appreciated.
(Please note that I'm a newcomer to android development)
I am customizing Jitsi to play a Wav file when a call is in progress.
I am facing trouble doing it, and would appreciate if you can help me out.
I can switch the data source before the call starts, by using a custom AudioFileMediaDevice and switching it on in CallPeerMediaHandler.
But I am having problems in replacing the datasource when the call is in progress.
=============================================================
I've tried the following but couldn't make it work.
1) I tried getting the device's output datasource and added a URLDatasource of the wav file using addInDataSource method. Didn't work.
DataSource dataSource = device.createOutputDataSource();
DataSource fileDataSource = Manager.createDataSource(new URL("file://resources/sounds/Sample.wav"));
((AudioMixingPushBufferDataSource)dataSource).addInDataSource(fileDataSource);
2) I tried adding a custom Capture device and switch it, but its not working too:
CaptureDeviceInfo2 fileDevice =
new CaptureDeviceInfo2("Recorded Audio 1",
fileDataSource.getLocator(), null, null, null, null);
((MediaServiceImpl) LibJitsi.getMediaService())
.getDeviceConfiguration().getAudioSystem().setDevice(AudioSystem.DataFlow.CAPTURE, fileDevice, false);
This is working for playback though, not as a capture device.
3) I even tried adding a new Audio system with the playback device as the file data source, but thats not working too.
=============================================================
I am new to libjitsi, so I'm having tough time trying to decode what is happening.
Any directions on how to resolve this would be great.
I made playback sound in call with this code:
public void startPlaying(CallPeer callPeer, DataSource soundDataSource) throws OperationFailedException {
assert callPeer instanceof CallPeerSipImpl;
CallPeerSipImpl cp = (CallPeerSipImpl) callPeer;
AudioMediaStreamImpl audioMediaStream = (AudioMediaStreamImpl) cp.getMediaHandler().getStream(MediaType.AUDIO);
AudioMediaDeviceSession deviceSession = audioMediaStream.getDeviceSession();
assert deviceSession != null;
assert deviceSession.getDevice() instanceof AudioMixerMediaDevice;
AudioMixerMediaDevice dev = (AudioMixerMediaDevice) deviceSession.getDevice();
dev.getAudioMixer().addInDataSource(soundDataSource);
}
Note that AudioMixerMediaDevice.getAudioMixer() has private access in libjitsi, so I made it public and recompiled.
I needed to play an audio file during a call, but only on the remote side of the call. So I played around a little bit with stokitos example and modified it for my needs. In case somebody ever needs it, here is what I did:
private void playAudioFromDataSource(final CallPeerSipImpl callPeer, final DataSource audioDataSource, final MediaDirection direction) {
final CallPeerMediaHandlerSipImpl mediaHandler = callPeer.getMediaHandler();
final AudioMediaStreamImpl audioMediaStream = (AudioMediaStreamImpl) mediaHandler.getStream(AUDIO);
final AudioMediaDeviceSession deviceSession = audioMediaStream.getDeviceSession();
if (null != deviceSession) {
if (RECVONLY == direction) {
// plays audio local only:
deviceSession.addPlaybackDataSource(audioDataSource);
} else {
final AudioMixerMediaDevice mediaDevice = (AudioMixerMediaDevice) deviceSession.getDevice();
final AudioMixer audioMixer = getAudioMixer(mediaDevice);
if (null != audioMixer) {
if (SENDONLY == direction) {
// plays audio remote only:
audioMixer.getLocalOutDataSource().addInDataSource(audioDataSource);
} else if (SENDRECV == direction) {
// plays audio on both sides of call (local and remote):
audioMixer.addInDataSource(audioDataSource);
}
}
}
}
}
private AudioMixer getAudioMixer(final AudioMixerMediaDevice device) {
try {
final Method privateGetAudioMixerMethod = device.getClass().getDeclaredMethod("getAudioMixer");
privateGetAudioMixerMethod.setAccessible(true);
final Object audioMixerObject = privateGetAudioMixerMethod.invoke(device, (Object[]) null);
return (AudioMixer) audioMixerObject;
} catch (final Exception e) {
log.error("Could not get AudioMixer", e);
}
return null;
}
NOTE: I sued reflection to get the private AudioMixer object. I admit it's not the cleanest approach, but it works. :)
What i want to do in my project is to play audio songs which are inside my Box account for that i am using box api . As i know we can not provide direct audio streaming for audio files in Box api for that i am trying to implement progressive download and playing audio file from sd card . i know i can play song inside on complete method of download but this is taking more time to download and than playing file . for that what i did i wrote my code for playing audio inside on progress method of downloading file but this method is getting called so many times because of that same song is playing multiple time at a time.
So is there any way to write code for progressive audio playing in Box api .if yes where should i write that ?
* Download a file and put it into the SD card. In your app, you can put the file wherever you have access to.

}
else if (status.equals(FileDownloadListener.STATUS_DOWNLOAD_CANCELLED)) {

Use something like these:
http://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/StreamProxy.java?r=41487c03f461942a5747378d197320412fe99442
http://www.java2s.com/Code/Android/File/StreamProxy.htm
Basically for progressive streaming, you proceed with the download as usual (in background) and you run a stream proxy (like a server in background) and push the data to your media player (you can use external media player or write a simple one by yourself, it is only few lines of code with Android media framework)
I have use something very similar with success.
In fact I am using the answer from this post (with minor modification)
MediaPlayer stutters at start of mp3 playback
I need to extract audio from a live stream on red5 and stream it separately. On nginx with rtmp module I'd just retranslate this stream via ffmpeg without videodata, but I have no idea how to do anything like this (with or without ffmpeg) on Red5.
The first link on google gave me this:
just register IStreamListeners on your IClientStreams, and then separate AudioData from VideoData in the RTMPEvents
But this doesn't help much. To be honest, this doesn't help at all. What are these IStreamListeners and how do I register them on IClientStream?
And, what is more misterious, how do I separate AudioData from VideoData in some RTMPEvents?
This is how your extend RTMPClient and capture the Audio or Video events
private class TestClient extends RTMPClient {
private int audioCounter;
private int videoCounter;
public void connect() {
private IEventDispatcher streamEventDispatcher = new IEventDispatcher() {
public void dispatchEvent(IEvent event) {
System.out.println("ClientStream.dispachEvent()" + event.toString());
String evt = event.toString();
if (evt.indexOf("Audio") >= 0) {
audioCounter++;
} else if (evt.indexOf("Video") >= 0) {
videoCounter++;
}
}
};
}
}
This simply counts the a/v events, but it will get you part of the way there. I suggest looking though the unit tests in red5 and there you can learn a lot.
