stop() called on an uninitialized AudioRecord.

[Ashish Tiwari]

Hi,
I am using this library and when I am recording second time and stopping, I am getting below error. Please suggest.
Thank You.

Error is

java.lang.IllegalStateException: stop() called on an uninitialized AudioRecord.

**Code to start and stop **

`View.OnTouchListener touchListener = new View.OnTouchListener() {
@OverRide
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (permissionToRecordAccepted && permissionToReadExternalStorage && permissionToWriteExternalStorage) {

                //startPulseAnimation();
                timerTextView.setVisibility(View.VISIBLE);
                countDownTimer.start();
                recorder.startRecording();
            }


        } else if (event.getAction() == MotionEvent.ACTION_UP) {

            timerTextView.setVisibility(View.INVISIBLE);
            countDownTimer.cancel();
            try {
                recorder.stopRecording(); // Here I am getting error.
                if (!TextUtils.isEmpty(mVerificationId)) {
                    mPresenter.configureVoice(mVerificationId, Utility.getDeviceId(), file().getPath(), audioBytes);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        return true;
    }
}`

This recorder.stopRecording(); runs before the recorder is actually initialized. Put these try and catch blocks into an if statement that checks if the recorder is not null first. Or simply create a flag isRecording that changes when you start and stop recording

I've got the same issue, i tried with if statement but that don't work, maybe I don't do it correctly. And I don't understand flag ?

[Anton Paliakov]

I use isRecording but I got the same problem.

I think this problem comes if your device don't support the sample rate you define like 44100 Hz, some devices supports and some not.

java.lang.IllegalStateException: stop() called on an uninitialized AudioRecord.
You will get this error only when the AudioRecord object is not properly intialized. It may happen if you use stopRecording() before calling startRecording().

[Daniel Lee]

from AOSP,

after stop is called, mState = STATE_UNINITIALIZED;
from startRecording ,

if (mState != STATE_INITIALIZED) {
           throw new IllegalStateException("startRecording() called on an "
                   + "uninitialized AudioRecord.");
       }

mState only resets from the constructor
=> construct new object for second record
