hello, how I can create visualizer for a media player running in service,
I went to add visualizer to my main activity and get media player from service to run the visualizer
thanks

i have used this in my build.gradle(:app) , but getting above error,pls help where i am wrong below is my build.gradle(:app) file

}

replace with

if (visualizer != null) {
    visualizer.release();
}

to prevent NullPointerException in case setPlayer is not called

i am creating a audio player using recycler view. Now i this app i am inserting two songs by myself
I am using circlebar visiualizer in sliding up panel.

So i am using com.chibde.visualizer.LineBarVisualizer for some visual effect to songs playing in MediaPlayer. But the thing is when i change activity and come back to the activity where song was playing with visualiser the visualiser is gone. I am aware that LineBarVisualizer uses audiosessionid fr effect to show up. I am even trying to save the audiosessionid in savedinstance and restoring on restoresavedinstance but it responds only to orientation change, not to activity change

`public int getAudioId() {
if (mBound) {
if (mediaPlayer != null) {
audioId = mService.getAudioId();
}
}
return audioId;
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("savedAudioID", getAudioId());

}

@Override
protected void onRestoreInstanceState(Bundle superState) {
    super.onRestoreInstanceState(superState);

    lineBarVisualizer.setPlayer(superState.getInt("savedAudioID"));

}

`

I want to set the player to 0 so whenever the music is played, the visualizer animation occurs. But it's not happening, my app is crashing.

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

Need the solution ASAP !!

Thankyou so much, looking forward to reply's

public class MonitorSoundFragment extends Fragment {

    private static final String TAG = "MonitorSoundFragment.class";

    private BarVisualizer envirnment_bar;

    public static MonitorSoundFragment newIntance() {
        return new MonitorSoundFragment();
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_monitor_sound, null);
        findViews(view);
        return view;
    }

    private void findViews(View view) {
        envirnment_bar = view.findViewById(R.id.environment_shower);
        envirnment_bar.setDensity(70);
        envirnment_bar.setColor(R.color.colorAccent);
        //获取AudioManager
        AudioManager audioManager = (AudioManager) getActivity().getSystemService(Context.AUDIO_SERVICE);
        envirnment_bar.setPlayer(audioManager.generateAudioSessionId());
        int volume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        Log.i(TAG, "current volume" + volume);
    }
}

this is my code, I find the parameter is int audioSessionId,So I used this method of audiomanager, but it doesn't seem feasible

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

hi thanks for making this but how can i customize the visualizers?
for example i want to change the max/min height of circle bar visualizer.

When I set media player id, goes back activity. It comes error

<Fatal signal 6 (SIGABRT), code -6 (SI_TKILL) in tid 26624 (Visualizer), pid 25990>

& crash the application

#50 (comment)

i am setting the density to minimize the width of the bar , but it also increases the speed of the visualizer
but i want slow speed of visualizer with the lower bar width

Is it possible to use the visualizer with Android text-to-speech?

My app uses Android text-to-speech to read paragraphs, and I'd like to add an audio visualizer so to have an animation according to the speech.

I find this audio visualizer very interesting, but I don't know how to use it with tts.

In the page examples it says you have to instantiate Media player, and shows this example:

mediaPlayer = MediaPlayer.create(this, R.raw.you_music);

But the fact is I'm not using MediaPlayer, but TTS for the audio. The library requires an audiosessionid to be passed to the player this way:

lineVisualizer.setPlayer(mediaPlayer.getAudioSessionId());

But I'm not finding any way to get the audiosessionid from tts, and inspected all the properties of the TextToSpeech instance, but no getAudioSessionId() or similar is present.

private lateinit var ttobj: TextToSpeech
    
    ttobj = TextToSpeech(this, this)
    ttobj.setLanguage(Locale.US)
    
    ttobj.setOnUtteranceProgressListener(object : UtteranceProgressListener() {
        override fun onStart(utteranceId: String) {
            //Here I would call setPlayer and pass an audiosessonid to start the visualizer.
        }
    
        override fun onDone(utteranceId: String) {
            runOnUiThread {
                ttsSpeechFinished()
            }
        }
    
        override fun onError(utteranceId: String) {
            Log.i("TextToSpeech", "On Error")
        }
    })
    
    fun doSpeech(){
        if (ttsStatus == TextToSpeech.SUCCESS){
            ttobj.speak("I'm going to read a paragraph for testing, right?", TextToSpeech.QUEUE_FLUSH, null,"")
        }
    }

The speech is working great, but I don't know how to "attach" the audio visualizer to the current tts audio sinthesys.

I've tried using AudioManager, that has a generateAudioSessionId() method:

var mAudioManager = activity?.getSystemService(AUDIO_SERVICE) as AudioManager
    val audioSessionId = mAudioManager.generateAudioSessionId()

But this audioSessionId is not working, and I'm obviously not sure I'm in the right direction.

Any help?

Will there be any demo for Xamarin Android?

Hi I don't know if it is the correct way but I have the "line visualizer" working with a service. It does leave a line where the visualizer is located on the MainActivity when service is stopped. The line remains when a new animation starts. I will post the fix for that when I get it sorted.

1. Create new java class
   public class Delegate { static MainActivity theMainActivity; }
   Then add this to your main activity in onCreate
   Delegate.theMainActivity = this;
   Finally add the visualizer code to your service
   ` public int onStartCommand(Intent intent, int flags, int startId) {

    ///////////
    LineVisualizer lineVisualizer = Delegate.theMainActivity.findViewById(R.id.visualizer);
    lineVisualizer.clearAnimation();
    lineVisualizer.setColor(ContextCompat.getColor(this, R.color.green));
    lineVisualizer.setStrokeWidth(1);
    lineVisualizer.clearAnimation();
    ///////////////
   
    String stUrl = intent.getStringExtra("URL");
    Uri uri =  Uri.parse( stUrl );
   
    player = MediaPlayer.create(this, uri);
    player.start();
    
    /////
    lineVisualizer.setPlayer(player);
    /////
    return Service.START_STICKY;
   

   }`

in API level 16 i receive this exception
Fatal Exception: java.lang.ArrayIndexOutOfBoundsException: length=49; index=49 at com.chibde.visualizer.BarVisualizer.onDraw + 85(BarVisualizer.java:85) at android.view.View.draw + 13458(View.java:13458) at android.view.View.getDisplayList + 12409(View.java:12409) at android.view.View.getDisplayList + 12453(View.java:12453) at android.view.ViewGroup.dispatchGetDisplayList + 2911(ViewGroup.java:2911) at android.view.View.getDisplayList + 12345(View.java:12345) at android.view.View.getDisplayList + 12453(View.java:12453)

i use CircleBarVisualizer in my music app and when i use setPlayer(AudioSession) method the app crashes
for fix this problem in BaseVisualizer.java$setPlayer(int audioSessionId) method after make a new visualizer add this line:

visualizer.setEnabled(false);

and the bug fixed :)

When audio pause or stop then the there is only show a simple line. If audio stop or pause then there should be show visualizer in Line Bar Visualizer.

Dear All,

I am doing music app, it is working fine when music play first time & linearbarvisualizer set media sessionid. I switch to another activity, music play in background & come to main activity linearbarvisualizer not showing. And i set media sessionid which is stored in sharedpreference, the error comes

Application crash & get error

<Caused by java.lang.IllegalStateException: setCaptureSize() called in wrong state: 2>

I have set linearbarvisualize enabled false but still get issue.

I have implemented this visualizer in my media player app, sometimes I am getting error like this.
Fatal Exception: java.lang.RuntimeException
Cannot initialize Visualizer engine, error: -3
Can you please let me know reason for this error and how to resolve it?

Could we have support for exoplayer?

My Scenario is that I have two fragment
1st Fragment Show All Audios
2nd Fragment Show Recently Played Audios

Visualizer Show on Both Fragments of the recycler view Position of the currently playing item

` public void enableVisulizer(BarVisualizer barVisualizer) {

    barVisualizer.setVisibility(View.VISIBLE);
    barVisualizer.setColor(context.getResources().getColor(R.color.equalizerAnimatedColor));
    barVisualizer.setDensity(20);
    barVisualizer.setPlayer(PlayerService.exoPlayerSessionID);
}` 

This method is called the first time, then starts the visualizer, while calling from another fragment to start the visualizer at that position, then the visualizer gets stuck at the first position (stops playback).

<com.chibde.visualizer.LineBarVisualizer android:id="@+id/visualizer" android:layout_width="match_parent" android:layout_height="250dp"/>

For the Line Visualizer
Usage
<com.chibde.visualizer.LineVisualizer android:id="@+id/visualizer" android:layout_width="match_parent" android:layout_height="250dp"/>

However the final SquareBar Visualizer has the correct usage case.

Multiple instances doesn't work. Only one will work

Hi,

I followed the Wiki, but I still got this error.

Caused by: java.lang.RuntimeException: Cannot initialize Visualizer engine, error: -3 at android.media.audiofx.Visualizer.<init>(Visualizer.java:218)

It would be nice to have a method to clear artifacts from the Visualizer.
This might be used in stations where you might use the android-audio-visualizer layout again in the same activity

i want to visualizer effect while recording audio is it possible or any other method that allow set dummy animation like that if any possibly then let me know thanks in advance

instead of com.chibde.audiovisulaizer.visualizer.LineBarVisualizer

          It's unfortunate i got the same error, has anyone solved this anyway... i got <br>
