I have successfully recorded the sound from microphone and can draw recorded sound in wav form. What I need is to draw graph dynamically when I record the sound (Like heart beat monitoring graph). Below is my code to record sound

MediaRecorder mediaRecorder;
private MediaPlayer mPlayer = null;
private static final String LOG_TAG = "AudioRecordTest";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_record);
buttonRecord = (Button) findViewById(R.id.buttonRecord);
buttonPlay = (Button) findViewById(R.id.buttonPlay);
buttonRecord.setOnClickListener(new View.OnClickListener() {
boolean mStartRecording = true;
#Override
public void onClick(View v) {
onRecord(mStartRecording);
if (mStartRecording) {
buttonRecord.setText("Stop");
} else {
buttonRecord.setText("Start");
}
mStartRecording = !mStartRecording;
}
});
buttonPlay.setOnClickListener(new View.OnClickListener() {

#Override
public void onClick(View v) {
onPlay(mStartPlaying);
if (mStartPlaying) {
buttonPlay.setText("Stop playing");
} else {
buttonPlay.setText("Start playing");
}
mStartPlaying = !mStartPlaying;
}
});
}
private void onRecord(boolean start) {
if (start) {
startRecording();
} else {
stopRecording();
}
}
private void onPlay(boolean start) {
if (start) {
startPlaying();
} else {
stopPlaying();
}
}
private void startRecording() {
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mediaRecorder.setOutputFile(mFileName);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
try {
mediaRecorder.prepare();
} catch (IOException e) {
e.printStackTrace();
}
mediaRecorder.start();
}

you could use getMaxAmplitude as explained in link

I am trying study how to use Android record and playback function.
Through Google Android record example(https://developer.android.com/guide/topics/media/mediarecorder.html), I want change the Layout and button.
But after I reset all of them, programing is not working, I do not know what is happen.
Please advise.

I have a simple class to record voice and playing it after record play file:

startPlaying();
} else {
//stopPlaying();
pausePlaying();
}
}
private void startPlaying() {
mPlayer = new MediaPlayer();
try {
mPlayer.setDataSource(mFileName);
mPlayer.prepare();
mPlayer.start();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
}
private void stopPlaying() {
mPlayer.release();
mPlayer = null;
}
private void pausePlaying(){
mPlayer.stop();
}
private void startRecording() {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
try {
mRecorder.prepare();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}

}
private void stopRecording() {
mRecorder.stop();
mRecorder.release();
mRecorder = null;
}
public MainActivity() {
mFileName = Environment.getExternalStorageDirectory().getAbsolutePath();
mFileName += "/audiorecordtest.3gp";
}

startRecord = (Button) findViewById(R.id.buttonStartRecord);
startRecord.setOnClickListener(new OnClickListener() {
boolean mStartRecording = true;
#Override
public void onClick(View v) {
onRecord(mStartRecording);
if (mStartRecording) {
startRecord.setText("Stop recording");
} else {
startRecord.setText("Start recording");
}
mStartRecording = !mStartRecording;
}
});
startPlaying.setOnClickListener(new OnClickListener() {
#Override

}
});
stopPlaying.setOnClickListener(new OnClickListener() {

if (mRecorder != null) {
mRecorder.release();
mRecorder = null;
}
if (mPlayer != null) {
mPlayer.release();
mPlayer = null;
}
}
}
I know how can I pause, but I don't know how can I run file again but from moment where I pause my file. Any ideas?
Change this :
private void pausePlaying(){
mPlayer.stop();
}
To:
private void pausePlaying(){
if(mPlayer.isPlaying()){
mPlayer.pause();
} else {
mPlayer.start();
}
}
Don't use .stop() to pause. In the MediaPlayer API you can see that .pause() would be the best option. If you reorganized
mPlayer.setDataSource(mFileName);
mPlayer.prepare();
To happen in your onCreate method you can avoid it resetting every time.

I am trying to get the maxAmplitude of a recorded piece of sound.
I made a soundrecorder which is working great, but when i use getMaxAmplitude to get the amplitude it always returns 0.
I looked all over the internet but couldnt find an working solution, so i hope someone can help me because im stuck atm.
Please keep in mind i'm a beginner ;)

You don't call your run() method anywhere. You shuld rather create a thread with this method:
private Thread thread = new Thread() {
#Override
public void run() {//...
}
}
};
And start this thread in a method of your choice, for examplre, startRecording(). Don't forget to interupt() it. And also, you'd better add a check a flag in you infinite while loop.
I am recording audio using AudioRecord class.I want to record audio into a particular file in my asset folder or resource folder.I think there is no problem in recording.but while reading buffer it is showing some problem(it is throwing NullPointerException).Can anyone suggest what may be the problem?
You can not save file inside Asset folder. Assets folder is read only instead of it you will have to save it in the internal or external storage of your device
Below there is a core to record the media file.

This is the example you can record audio as well as play audio
You can store recorded file in following places
1) File directory of your app
2) External directory(SD card)
3) Network
