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 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

you could use getMaxAmplitude as explained in link
I use android.media.AudioRecord.
/*initialize AudioRecord*/
long time = System.currentTimeMillis();
audioRecord.startRecording();
When I start audioRecord with method startRecording(), I want to get real time of device start recording. My time is not real...
Please, help me!
Thank you!
Check out this example
long time = System.currentTimeMillis();
Date date = new Date(time);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss z"); // the format of your date
sdf.setTimeZone(TimeZone.getTimeZone("GMT-4")); // give a timezone reference for formating (see comment at the bottom
String formattedDate = sdf.format(date);
System.out.println(formattedDate);
I think MediaRecorder Will be the better option for recordind Audio and you can record the real time audio.

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.
