MediaRecorder not getting initialized properly "start failed -19 which means "NO_INIT"" and "E/MediaRecorder: stop called in an invalid state: 0"

Question

i want to record a video (with audio) from this app

but as soon as i press start recording it gives "E/MediaRecorder: start failed: -19"

i referred to this link ---> Android MediaRecorder - "start failed: -19" and according to them i set the supported videoSize but again i failed

and i have set the method calls according to the state diagram given on ---> "developer.android.com/reference/android/media/MediaRecorder.html" website

and i have set audio and video parameters as given on ---> "developer.android.com/guide/appendix/media-formats.html" website

but nothing seems to work :(

i am testing this on my phone Mi Redmi 2 running MIUI

this is how UI looks like ---> Cam UI

this is my code below:-

/*to Start recording*/
  public void startRecording() {
    Log.e(tag, "Begin StartRecording");
    if (mRecorder != null) {
        mRecorder.stop();
        mRecorder.release();
    }
    mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mRecorder.setAudioChannels(1);
    mRecorder.setAudioSamplingRate(24);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
    mRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
    mRecorder.setAudioEncodingBitRate(24);
    mRecorder.setVideoEncodingBitRate(56);
    final List<Camera.Size> mSupportedVideoSizes = getSupportedVideoSizes(camera);
    for (Camera.Size str : mSupportedVideoSizes)
        Log.e(tag, "mSupportedVideoSizes "+str.width + ":" + str.height + " ... "
                + ((float) str.width / str.height));

    File dir = Environment.getExternalStorageDirectory();
    try {
        audiofile = File.createTempFile("sound", ".mp4", dir);
    } catch (IOException e) {
        Log.e(tag, "external storage access error");
        return;
    }
    mRecorder.setOutputFile(audiofile.getAbsolutePath());
    mRecorder.setVideoSize(176, 144);
    mRecorder.setVideoFrameRate(12);
    mRecorder.setMaxDuration(20000);
    mRecorder.setPreviewDisplay(surfaceHolder.getSurface());

    try {
        mRecorder.prepare();
    } catch (IllegalStateException | IOException e) {
        e.printStackTrace();
        Log.w(tag, e);
    }
    try {
        mRecorder.start();
        Toast.makeText(this, "Recording....", Toast.LENGTH_SHORT).show();

    } catch (Throwable t) {
        t.printStackTrace();
        Log.w(tag, t);

    }

}


 /*To stop recording*/
public void stopRecording() {
    Log.e("", "Begin StopChange");
    if (mRecorder != null)
        try {
            mRecorder.stop();
            Toast.makeText(this, "Recording STOPPED .. ", Toast.LENGTH_SHORT).show();
        } catch (RuntimeException e) {
            e.printStackTrace();
        } finally {
            mRecorder.reset();
            mRecorder.release();

            mRecorder = null;
        }
}

here is the Android Manifest permissions :---

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

yes ... i have 4 buttons here 1) start preview 2) stop preview 3) start recording 4) stop recording — Vibhore Agg, Feb 24 '16 at 06:55
See standard example here as it is hard to debug your problem http://developer.android.com/reference/android/media/MediaRecorder.html — , Feb 24 '16 at 07:06
yes i started this by refering to this page only but dont know why i am getting 0 byte file — Vibhore Agg, Feb 24 '16 at 07:09
should i post only the main piece of code rather than posting it as a whole ? — Vibhore Agg, Feb 24 '16 at 07:09
No. I think your configuration for the recording is invalid combination. Please follow the example exactly. After that you can modify it. — , Feb 24 '16 at 07:11
i did as in that link .. but now getting "E/MediaRecorder: stop called in an invalid state: 0" in logcat — Vibhore Agg, Feb 24 '16 at 07:33

i referred to "http://stackoverflow.com/questions/10496969/android-mediarecorder-start-failed-19" this link .... and set the supported videosize but still getting this start failed -19 error — Vibhore Agg, Feb 24 '16 at 08:44
What I was meaning by the question is that you did something wrong with recorder. I expect you called `release()` and after that attempted to start it. Please FOLLOW the example from the standard docs EXACTLY. — , Feb 25 '16 at 06:38
I am doing exactly what is shown in the Standard Docs .... now i have posted only the start and stop recording methods code , so u can refer that to see — Vibhore Agg, Feb 25 '16 at 10:10
Please make only two buttons: start record, stop record. Click start record then click stop recording. See what is the result — , Feb 25 '16 at 10:24
when i click start record after Start failed -19 error logcat shows "I/Choreographer: Skipped 37 frames! The application may be doing too much work on its main thread." — Vibhore Agg, Feb 25 '16 at 11:14

Try to set mRecorder.setVideoFrameRate(30); before mRecorder.setVideoSize(320, 240);

Hope this helps.
