waveinapp's Issues

Cannot initialise visualizer engine, error -3

First of all thanks for providing this library, it looks great.

Only thing is, I’m having a problem where I run into the following error:

java.lang.RuntimeException: Cannot initialize Visualizer engine, error: -3

The error is triggered at the following line:

VisualizerDbmHandler vizualizerHandler
= DbmHandler.Factory
.newVisualizerHandler(
PlayActivity.this,
state.getExtras().getInt(StreamingService.AUDIO_SESSION_ID)
);

The AUDIO_SESSION_ID is provided by an ExoPlayer instance in a background service, though it seems the value it is returning is 0, which I read is deprecated? I have also made sure to request runtime RECORD_AUDIO permission before attempting to initialise the visualiser.

Marshmallow permissions

I have included the Manifest.permission.RECORD_AUDIO and Manifest.permission.MODIFY_AUDIO_SETTINGS but still I'm getting "Cannot initialize Visualizer engine, error: -3" on Marshmallow Devices.

i cant open in android studio

i am getting error
Error:org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection
Possible causes for this unexpected error include:

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

It does not work neither on a virtual device targeting Android 10 nor a physical Samsung Note 8 targeting Android 9

It does not work, compiling with Android studio this exact project. It does not show any errors on console by the way.
Emulator: API 30 Target Android 10+0 x86
Physical device: Samsung Note 8 Model SM-N950F Android 9.

It only shows the first static colored bars.

Thanks:!

Workaround file consumes 1mb (while for many unnecessary)

This is not so much an issue as a request. The workaround file (https://github.com/Cleveroad/WaveInApp/tree/master/library/src/main/res/raw) is even when compressed 1MB in size, thus making up 20% of my final app size. This audio file is a multiple of the size of all code and other resources of this library combined.

Because I use a familiar stream, and because I play it with ExoPlayer, a valid audioSessionId is always present and therefore I do not use the workaround.

It would be amazing if you could either:

Switch to a workaround that is based on a algorithm or randomiser, rather than playing a fallback media file.
Let users include the fallback file theirselves, and then let them optionally pass the fallback file resource ID to the library when initialising the library. (Example)
Provide the fallback file option as an add in:
'com.cleveroad:audiovisualization-fallbackhack:1.0.0'
If the above is not possible, the use of a smaller audio file (shorter and looped for example).

How can i use it with android MediaRecorder?

I am using MediaRecorder to record audio. How can i link this library with my recorder. Here's my recorder:

public void MediaRecorderReady(int recTime) {
    mediaRecorder = new MediaRecorder();
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mediaRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
    mediaRecorder.setMaxDuration(recTime);
    mediaRecorder.setOutputFile(AudioSavePathInDevice);
}

Crash when implementing library via XML

I just simply copy paste what you had been posted on github:The xml code to include the library int my project,but your greatest library giving such exception

Thank you for great work...This crash i think you have to know what does it means

How can I dynamically modify WavesFooterHeight

getting runtime exception first time when app is started

java.lang.RuntimeException: Unable to start activity ComponentInfo{purvil12c.musicplayer/purvil12c.musicplayer.MainActivity}: java.lang.RuntimeException: Cannot initialize Visualizer engine, error: -3

I've included all permissions in menifest

Junk file automatically gets included in the res folder.

The file named "av_workaround_1min.mp3" automatically gets included in the final apk. It takes around 938kb which is 28% of my app.

Visualizer Defect

The Visualizer doesn't seem to work on nexus 5x when there was song played on background, the same problem was seen on samsung devices. Also i saw E/Audio record -38 on logcat.

Nexus 5X

Hi guys, I ve been playing with your lib for a while now, and it works perfectly on my LG G3. But when I run the sample on a Nexus 5X , no wave are moving..Permissions are OK and it seems to go into "ondatareceived".

Any idea ? Maybe problems of compatibility with this device??

Anyway, thanks for the lib !

Layer frequency

Hey. Firstly, thanks for this great and useful library. I have created test app on myself and works like charm!

But when I test only two layer, I saw it's really cool movement. Is there any api to set frequency to layer for seeing more exhilaration?

Thank. Best regards.

I have called the music player from MusicService.java

AudioVisualizationFragment.java

audioVisualization = (AudioVisualization) view;
        audioVisualization.linkTo(DbmHandler.Factory.newVisualizerHandler(getContext(), MusicService.mPlayer));

MainActivity.java

private void openFragment() {
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.audio_player_lyt, AudioVisualizationFragment.newInstance())
                .commit();

    }

How could I solve this error?

Xamarin Android

hi, glad to see a library like this one.

Can you please make this library available for Xamarin.android too?

waves not work when I paly audio

waves not work no matter with MediaPlayer or 3rd Players, it just calme down and nothing happened! even I run your WaveInApp example, still not work. i think you should check and update your code in the project.

ConcurrentModificationException

First Thanks a lot for your lib, it works pretty well.
Unfortunately, I got some crashs that happens .

  java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:806)

 at java.util.AbstractCollection.addAll(AbstractCollection.java:76)
at com.cleveroad.audiovisualization.GLWaveLayer.update(GLWaveLayer.java:92)

It comes from this part :

/**
     * Update waves and bubbles positions.
     * @param dt time elapsed from last calculations
     * @param dAngle delta angle
     * @param ratioY aspect ratio for Y coordinates
     */
    public void update(long dt, float dAngle, float ratioY) {
        float d = dt * dAngle;
        isCalmedDown = true;
        for (GLWave wave : waves) {
            wave.update(d);
            isCalmedDown &= wave.isCalmedDown();
        }
        usedBubbles.addAll(producedBubbles);
        producedBubbles.clear();
        Iterator<GLBubble> iterator = usedBubbles.iterator();
        while (iterator.hasNext()){
            GLBubble bubble = iterator.next();
            bubble.update(dt, ratioY);
            if (bubble.isOffScreen()) {
                unusedBubbles.add(bubble);
                iterator.remove();
            }
        }
    }

My app uses the Android spotify SDKs

Any idea how I could avoid the crash ?

Sound wave visualization during MediaRecording?

Is this library capable of showing some kind of visualization when a MediaRecorder is recording sound from the MIC of the phone?

If so, is there an example of it?

Throws exception if RECORD_AUDIO permission is removed

Why i need to add record audio permission even if i am not recording any thing.

Here is my code:

   @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        audioVisualization = (AudioVisualization) view;
        initMediaPlayer();
        audioVisualization.linkTo(DbmHandler.Factory.newVisualizerHandler(getContext(), mediaPlayer));
        play();
    }

Add SpeechRecognizer support

Hi,

This is more a feature request instead of an issue. Would it be possible to add integration for the SpeechRecognizer. A good integration would maybe be to use the RecognitionListeners onRmsChanged method in order to change the wave's height.

Looking forward for your feedback!

Can we use this Inside Recyclerview while Playing Audio in Recyclerview TextureView

Crash with speech recognizer and Audio record

Hi,

I tried to run this code on my Galaxy S4 but it crashes with the error below:

How to use this library?

Hello , first of all , this visualizer looks awesome . Would be really nice to use it. But as I am a new developer , I can't figure out how to use it :( . I tried some stuff but didn't really work out. My intention is having this visualizer while playing an audio stream from network.

This is what I tried :

` audioVisualizationView = new GLAudioVisualizationView.Builder(this)
.setBubblesSize(R.dimen.bubble_size)
.setBubblesRandomizeSize(true)
.setWavesHeight(R.dimen.wave_height)
.setWavesFooterHeight(R.dimen.footer_height)
.setWavesCount(7)
.setLayersCount(4)
.setBackgroundColorRes(R.color.av_color_bg)
.setLayerColors(R.array.av_colors)
.setBubblesPerLayer(16)
.build();
layout.addView(audioVisualizationView);

    audioVisualization=(AudioVisualization)audioVisualizationView;
    audioVisualization.linkTo(DbmHandler.Factory.newVisualizerHandler(this, 0));`

And there is a mediaplayer set up for audio playback. How do I link two together?

VisualizerDbmHandler not work in version 1.0.0

i use below method:

// set audio visualization handler. This will REPLACE previously set speech recognizer handler
VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);
audioVisualization.linkTo(vizualizerHandler);

i use both :
VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);

and

VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), mediaplayer);

both method does not work

How can I know whether waves are being shown correctly?

When I run my app on Genymotion emulator, just black screen is shown instead of waves (GLAudioVisualizationView). I would like to hide the GLAudioVisualizationView if that happens. How can I detect whether waves are being displayed correctly or not?

UPDATE:
I just noticed If I rotate the device that black screen is gone and waves are showing up. But, what is the workaround here?

How can i save file when recording is finished?

I want to save file in device when recording is finished.

this is awesome

Playing View Can't find

Hey guys, I can't find the page where implement playing view over the wave visualization.

please help me.

Can't handle Audio Focus event after attach MediaPlayer to the VisualizerDbmHandler.

Hi everyone, after attach a MediaPlayer's instance to the VisualizerDbmHandler via the code:

musicHandler = VisualizerDbmHandler.Factory.newVisualizerHandler(this.getApplicationContext(), mediaPlayer);

my AudioFocus Listener doesn't work anymore. Has the VisualizerDbmHandler class subscribe other Listeners?

my project: https://github.com/MinhDang685/MediaPlayerApp/

Visualizer not working when initialize VisualizerDbmHandler with the parameter audioSessionId=0

@Iojjj , I have found your comment in issue 36 https://github.com/Cleveroad/WaveInApp/issues/36 that you said

Pass "0" as audioSessionId to capture mix output of device.

but when I initialize the VisualDbmHandler by the code below and play media with a MediaPlayer instance in the same app, the wave aren't showing. The visualizer only work with audio play from another app (I've try to play a song from my phone music app and It work)
VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);
How can I fix that?
Thanks

Customizing threshold/inertia on waves?

Really cool lib!

Is there a way to adjust the minimum audio threshold, it seems to me that each way from the top to bottom have a increasing threshold, meaning given the same volume of input, the top wave moves the most and the bottom the least.

Is there a way to customize this threshold?

How can i Animate wave without play or record
