Since doing the recent SDK update in Processing for Android:

| google usb\_driver | 11.0.0 | |
| --- | --- | --- |
| Android SDK Build-Tools | 26.0.2 | |
| Google APIs Intel x86 Atom System Image | 14 | |
| Android SDK Platform 26 | 2 | |
| Android SDK Build-Tools | 26.0.3 | |
| Android SDK Tools | 26.1.1 | |
| Android SDK Platform-Tools | 29.0.0 | |

The Sound Library is no longer functioning. I get this error:

java.lang.UnsupportedOperationException: Cannot create AudioRecord  
at android.media.AudioRecord$Builder.build(AudioRecord.java:626)  
at processing.sound.JSynAndroidAudioDeviceManager$AndroidAudioInputStream.start(Unknown Source:66)  
at com.jsyn.engine.SynthesisEngine$EngineThread.run(Unknown Source:29)  
I installed Processing 3 on a new PC and received the same error.  
Anyone have any ideas

Please provide a code snippet or any links that you are following. I am interested to know if you are referring to the Sound Library offered in Java or are you using any other resource.

I have set the audio record permissions, but my app doesn’t record. It only plays a couple of .wav files. The app was working. The audio play back was working for the several months I’d been coding and testing it. Since the update I mentioned, using processing.sound.\*, does not seem to be functioning in Android mode. I tried it on 2 different windows 10 PCs

Ok, please provide snippet including the recording part and I could try to repro as I have a Win 10 machine as well.

As a test I tried the “SimplePlayback” Processing 3 Sound example.  
It worked in JAVA mode; giving this INFO:  
Jun 11, 2019 12:32:42 PM com.jsyn.devices.javasound.JavaSoundAudioDevice   
INFO: JSyn: default output latency set to 80 msec for Windows 10

But in Android mode gave the error I mentioned at the beginning of this topic.

Here is the sketch, slightly modified:  
import processing.sound.\*;  
SoundFile soundfile;  
void setup() {  
//fullScreen();  
size(640, 360);  
background(255);  
soundfile = new SoundFile(this, “vibraphon.aiff”);  
println(“SFSampleRate= " + soundfile.sampleRate() + " Hz”);  
println(“SFSamples= " + soundfile.frames() + " samples”);  
println(“SFDuration= " + soundfile.duration() + " seconds”);  
soundfile.loop();  
}  
void draw() {  
float playbackSpeed = map(mouseY, 0, width, 0.25, 4.0);  
soundfile.rate(playbackSpeed);  
float panning = map(mouseX, 0, width, -1.0, 1.0);  
soundfile.pan(panning);  
}  
void mouseDragged(){  
float amplitude = map(mouseY, 0, height, 0.2, 1.0);  
soundfile.amp(amplitude);  
}  
I should mention that other than no sound, in Android mode, the apps work fine

My app does not record audio. Only playback sounds. Not coded to record.  
It’s quite odd the error refers to audio recording

Hello, I discovered the library Cassette which works very well to play sound file. It can be downloaded in the processing editor.
