Android media sound Recorder Start failed

My application got crashed whenever i press start button. Logcat says its because of start method failed. I google the error but i didn't find anything. It is giving exception at the native method Start(v);
Here is my logcat :

You save the temporary file as type, m4a:
outputFile = File.createTempFile("sound", ".m4a", sampleDir);
but you have the wrong output format (3gp):
myRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
Solution:
If you'd like to save the recorded file as a 3gp format, you'd have to save the file as:
outputFile = File.createTempFile("sound", ".3gp", sampleDir);
else, If you'd like to save as an m4a format, you'd have to change the output format as follows:
myRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
Here's a list of the available formats

I had the same problem. Because I also have MediaPlayer, I solve this problem by the code:
mediaPlayer.setAudioStreamType(AudioManager.ADJUST_LOWER);
this solve my problem.

FileOutputStream out = new FileOutputStream(temp);
byte buf[] = new byte[2000];

out.write(buf, 0, numread);
} while (true);
mediaPlayer.setDataSource(tempPath);
try {
stream.close();
} catch (IOException ex) {
Log.e(TAG, "error: " + ex.getMessage(), ex);
}
}
}
How can I used to stream files from another application program?
When I play video from main activity it plays and when I quit and go to file explorer and chose my player from custom dialog box and open I have that problem with uriString...

When navigating through your files you can set a clicklistener on a thumbnail. I use this code to fire up a full-screen video editor:
thumbNail.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (pathType.equals("image")) {
<snip>
}
else {
// music file
}
else {
// must be video
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(cmsURL + pathListFull,"video/mp4");
PackageManager packageManager = getActivity().getPackageManager();
List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);
boolean isIntentSafe = activities.size() > 0;
if (isIntentSafe) {
startActivity(intent);
}
else {
Log.d("SHOWFILE", "no intents available");
}
}
}
});

The problem might be with the video encoding. Android Froyo and Gingerbread doesn't support H264 formats other than "Baseline" H264. So if your video is Mp4 & H264 encoded make sure its "AVC baseline" encoded. Use some tools like "Media info" in windows/Linux and check your video encoding. Convert the video to Baseline if possible.
An alternative workaround is to skip the Videoview and use a video play intent and redirect the playback to an app. User will be prompted to pick a player to handle the playback. Obviously if the video view cant play the file, the default player also wont be able to handle the file. you can choose some other installed player like Mx-Player which will stream the file perfectly.
Hope that solved your issue.

Try correct video url with protocol: http://www.ooklnet.com/files/368/368007/video.mp4

When I press the record button, Is starts recording. When I press the play button, It starting playing. When I again press the play button, I stops playing. The important issue which I am facing is the sound is not heared..? Please do me a needful. I am new to android..

Why you are resetting the recorder object immediately after recording .
