I have make one application in android in which i take three buttons in xml and in java i set the onclick event,
when play button is clicked song is prepared and play,
when stop button is clicked song is stopped,
when pause button is clicked song is paused.
But my problem is that when I clicked play button song is played after i click on stop button then song is stopped after I clicked on play button, but at this time song is not played,
the code I created for this app. is given below.
package com.mydemo;
import java.io.IOException;
import android.app.Activity;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MydemoActivity extends Activity {
/** Called when the activity is first created. */
Button bPlay,bPause,bStop;
MediaPlayer mp;
int position = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mp = MediaPlayer.create(this, R.raw.fluet);
bPlay = (Button) findViewById(R.id.bPlay);
bPause = (Button)findViewById(R.id.bPause);
bStop = (Button) findViewById(R.id.bStop);
bPause.setVisibility(View.GONE);
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer arg0) {
position = 0;
bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
bPlay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
if(position > 0)
{
mp.seekTo(position);
mp.start();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
bPlay.setVisibility(View.GONE);
bPause.setVisibility(View.VISIBLE);
}
});
bPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
if(mp!=null)
{
mp.pause();
position = mp.getCurrentPosition();
}
bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
bStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
mp.stop();
position = 0;
bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
}
}
see this Updated code:

bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
bPlay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
if(mp.isPlaying() == false)
{
try {
mp.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
}
bPlay.setVisibility(View.GONE);
bPause.setVisibility(View.VISIBLE);
}
});
bPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
if(mp!=null)
{
mp.pause();
position = mp.getCurrentPosition();
}
bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
bStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
mp.stop();
position = 0;
bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
}
}
Edit ::
you need to apply condition in play event like ::
if(mp.isplaying == false)
{
//play the song
}
bStop.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View arg0) {
mp.release();
position = 0;
bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);
}
});
bStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
if(mp.isplaying == false)
{
mp = MediaPlayer.create(this, R.raw.fluet);
}
}
});

I wanna make "Play/Stop" button. When button "Play" is clicked, the song must be played and its text should be converted into "Stop" and when "Stop" is clicked, the button text should be changed into "Play" again and song should start again to play from the beginning.

btn_playStop = (Button)findViewById(R.id.btn_play_stop);
btn_playStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying() && flag==true){
stopSong();
}
else if (flag == false){
playSong();
}
}
});
}
public void playSong(){
mediaPlayer.start();
btn_playStop.setText("Stop");
flag = true;
}
public void stopSong() {
mediaPlayer.stop();
btn_playStop.setText("Play");
flag = false;
}
}
You must call mediaPlayer.prepare(); if you called mediaPlayer.stop(); so in the first time you can just call mediaPlayer.start(); but in the next times you should call mediaPlayer.prepare(); before mediaPlayer.start();
public void playSong(){
try {
mediaPlayer.prepare();
} catch (IOException e) {
}
mediaPlayer.start();
btn_playStop.setText("Stop");
flag = true;
}

When the screen is locked your onPause is being called, and you are explicitly stopping the player there.
I could not resolve this media player error which says "stop called in state 1".my media player actually delays for few seconds before moving on to the next music.can anyone help me.
this might help u...

i've been trying to record and play recorded audio in android . I've used MediaRecorder and MediaPlayer class for the same.
My code contain 3 segments:

playaudio
But there's an error in my code fragement and whenever i execute it ,the startrecording() function implements catch block.

public class Recordplay2Activity extends Activity
{
Button play1,record1,stop1;
TextView status1;
MediaRecorder m1=null;
MediaPlayer m2=null;
String path;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
play1=(Button)findViewById(R.id.play);
record1=(Button)findViewById(R.id.record);
stop1=(Button)findViewById(R.id.stop);
status1=(TextView)findViewById(R.id.status);
OnClickListener recordListener = new OnClickListener()
{
public void onClick(View v)
{
startrecording();
}
};
OnClickListener stopListener = new OnClickListener()
{
public void onClick(View v)
{
stoprecording();
}
};
OnClickListener playListener = new OnClickListener()
{
public void onClick(View v)
{
playaudio();
}
};
record1.setOnClickListener(recordListener);
stop1.setOnClickListener(stopListener);
play1.setOnClickListener(playListener);
}
public void startrecording()
{
status1.setText("GET READY FOR RECORDING");
try
{
m1=new MediaRecorder();
m1.setAudioSource(MediaRecorder.AudioSource.MIC);
m1.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
m1.setOutputFile(path);
m1.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
m1.prepare();
m1.start();
}
catch(Exception e)
{
status1.setText("ERROR IN startrecording FUNCTION ");
}
}
public void stoprecording()
{
try
{
status1.setText("TIME TO STOP MEDIA");
m1.stop();
m1.reset();
m1.release();
}
catch(Exception e)
{
status1.setText("ERROR IN stoprecording FUNCTION");
}
}
public void playaudio()
{
status1.setText("PLAYING RECORDER AUDIO");
try
{
m2=new MediaPlayer();
m2.setDataSource("/sdcard/output.3gp");
m2.prepare();
m2.start();
}
catch(Exception e)
{
System.out.println("ERROR in playaudio FUNCTION");
}
}
}
I solved it. I changed AudioEncoder from:
m1.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB)
to:
m1.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT)
