stop() called on an uninitialized AudioRecord. about omrecorder

[dbof10]

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

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 ?

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().
