Android MediaRecorder - IllegalStateException

Question

the part of the code that throws exception:

        recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);

        recorder.setOutputFile("test.3gp");
        recorder.prepare();
        recorder.start();

and i'm getting this exception:

E/MediaRecorder: start failed: -38

the "recorder.start()" is causing this. also when i'm stopping the record, getting this: "stop called in an invalid state: 0" btw - got all the permissions i need in the manifest. thanks!!

EDIT

i added "Thread.sleep(2000);" before "prepare()" & "start()", and now it saved a 3gp file in the correct path, but the exceptions are still there - on start() & on stop(). why is it happening?!

i think you might have problem with file path. use full path ex Envirement.getExternalStorage()+File.seperator+"test.3gp"; also check storage permission. — Imtiyaz Khalani, Feb 15 '17 at 15:06

If you targeting greater then 22 then you must have to implement runtime permissions. See here for how to implement runtime permission in android.

It doesn't seem like this is the problem – Jahrk Feb 15 '17 at 15:16
Please check path of file and also replace default output line. `mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);` – Najeeb Idrees Feb 15 '17 at 15:22
not working, thanks for trying. i edited the question, please read it – Jahrk Feb 15 '17 at 15:27
this problem causing by this Audio source `recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);` not working on your device and android! change that to `recorder.setAudioSource(MediaRecorder.AudioSource.MIC);` – Najeeb Idrees Feb 15 '17 at 15:31
MIC throws the same exception. Also maybe i should added, the error i get when i stop the record: "stop called in an invalid state: 0" – Jahrk Feb 15 '17 at 15:33
