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 :
08-22 18:44:23.420: E/MediaRecorder(3607): start failed: -2147483648

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.

The issue is it's playing good sometimes and sometimes it's stopping when we press back button or swiping other apps on home screen.I want to show the title track,image on UI.But with this code it's showing wrong images for some songs and for some it's even not showing the image even if the image exists.And after back screen pressed and so when we use other apps and get back to this It's showing simply TextView and normal android image.Is recreation of activity needed?Can we call Activity method from Service?How to solve the issues?Please help me.

You need background music service and communicate with Activity with message or bond activity to service, not call Activity method from service, that will cause cross process problem.
I actually opensource a Music Player with Background service, Lyric, from a business project I have wrote, you check this out:https://github.com/Wangchao0721/MusicPlayer
But I haven't got time to fill Readme for it, just check MediaPlayerActivity.java in activity package, you gonna know how to use this.

How to stop the Background running service in android?

Intent svc=new Intent(BeapSoundActivity.this, BackgroundService.class);
pendingIntent = PendingIntent.getService(BeapSoundActivity.this, 0, svc, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 2);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 10*1000, pendingIntent);
I am using the above code to start my service in mt onCreate(),
I just want to stop this service when I click a Button to change my Activity
I used this line in my Button Click
stopService(new Intent(BeapSoundActivity.this, BackgroundService.class));
But it didnt worked for me
Here is my BackGroundService class

you created an alarm that start your service every 10 seconds. did you canceled it before stopping the service? (if not, use (AlarmManager)getSystemService(Context.ALARM_SERVICE).cancel)

I have created an intent service to start the music for my app in the background.
It is working, but my log-cat is flooded with the messages:

Permissions are needed. Put these in AndroidManifest.xml:
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
I tested it under android emulator 2.2 so my minSdkVersion is 8.
