android play one sound at a time

I am stumped on this and I have referenced so many other posts. I'm not asking for anyone to complete my code but simply to point out where I'm going wrong and steer me into the right direction. I want to play an audio file when I click a image button but have it stop when another image button is clicked. The problem I'm having is if I press all the image buttons they will all play audio at the same time.

update: now the problem is the pinkaudiotest is always the first audio file to play no matter what image button I click. I have to click a second time to hear the correct audio file.

You are creating a new MediaPlayer instance every click. Simply use a single one.
if (media.isPlaying()) {
media.stop();
media.release();
media= MediaPlayer.create(context, R.raw.purpleaudiotest);
} media.start();

how to play sound in android

I want to play music in my app when application starts. I tried many codes but nothing is working for me and i'm not getting any error.Can somebody please help me regarding this issue.Thanks in advance.
public class Login extends Activity {
EditText edName, edPassword;
String userName,password;
MediaPlayer mp;
#SuppressLint("NewApi")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
mp = MediaPlayer.create(getApplicationContext(), R.raw.startsound);
ActionBar actionBar = getActionBar();
actionBar.hide();
edName = (EditText) findViewById(R.id.editText1);
edPassword = (EditText) findViewById(R.id.editText2);
mp.start();
}
public void SignInClick(View V) {
userName = edName.getText().toString();
password = edPassword.getText().toString();
if (userName.equals("")) {
Toast.makeText(Login.this, "Username is empty", Toast.LENGTH_LONG).show();}
else if (password.equals("")) {
Toast.makeText(Login.this, "Password is empty", Toast.LENGTH_LONG).show();
}
else {
Intent intent=new Intent(Login.this,Home.class);
startActivity(intent);

Android media player progress bar rest to "0" when stop music

I put one song into an app (tabhost) and I have progress bar, play button, stop button, loop button.
The function I want is:
when user plays the music, the progress bar starts to run from "0"
when user presses stop, the progress bar stops at where it was, waits for the user to press play again, and then continues where it left off
I might change the button name to "pause" later, but this is the function I need right now.
Right now, 2 issues:
When stop is pressed, the progress bar returns to "0", but the music resumes playing from where it left off (music not playing from very beginning)
The progress bar runs faster than desired; it runs to the end before the music ending.
Here is my code, hope someone could help thank you so much:

Correct method to use MediaPlayer in android app

sorry my english, but I'm from Brazil and I used the google translator.
Well, I'm struggling in this application where I am trying to make a streaming an online radio, works fine in version 2.2, but version 4.0 does not work. No error occurs, simply does not work. Below is my code.
I appreciate any help.

setContentView(R.layout.activity_main);
play();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void stop(){

if(player.isPlaying()){
player.stop();
}
}
public void play(){
if(player.isPlaying()){

} else {
Toast.makeText(getApplicationContext(), "Preparando...", Toast.LENGTH_SHORT).show();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
try {
player.setDataSource(url);
} catch (IllegalArgumentException e) {
e.printStackTrace();

}

}
public void onClick(View v) {

play();

}
}
}
Hello, excuse my insistence but I still have not found the solution to my problem and do not know how to solve, I have once again asking for your help to solve this problem.
The application runs in versions 2.x and 3.x but not in version 4.x. Below is a link to download the project, to which you can take a look and help me.
http://nsi.inf.br/RadioMiriam.rar (removed)

i downloaded your project and it actually returns error Code:
E/MediaPlayer( 1976): error (-38, 0)
It is caused by starting mediaplayer before it is prepared.
I have made few changes and it started to work. You should :
Set onPrepared listener on MediaPlayer (i.e. in onCreate)
player.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
Remove player.start() from your play() method
Set datasource in this way (in your play() method)
player.setDataSource(this, Uri.parse("http://69.64.48.96:9880/"));
It works on my HTC Sensation with Android 4.0.3
If you need any assistance please let me know.
EDIT: i forgot, i also removed
player.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
It is redundant

The prepare() call is probably blocking the UI thread (which android 4.0 hates it when you do that)
You will need to this work in a background thread like an asynctask. Here is a anonymous version of implementing AsyncTask to run play() in the background.
public void onClick(View v) {
final int id = v.getId();
switch (id) {
case R.id.btnPlay:
new AsyncTask<Void, Void, Void>(){
#Override
protected Void doInBackground(Void... voids) {
play();
return null;
}
}.execute();
break;
case R.id.btnStop:
stop();
break;
}
}
You will need to read up a bit about MediaPlayer's states (playing, preparing, stopped, etc) to learn why calling prepare will block the UI thread (
for more info on AsyncTasks

You haven't set any link between buttons in your .xml file and your code. onClick method is never called even though you are pressing the buttons.
Replace your onCreate method with this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button playButton = (Button) findViewById(R.id.btnPlay);
playButton.setOnClickListener(this);
Button stopButton = (Button) findViewById(R.id.btnStop);
stopButton.setOnClickListener(this);
play();
}

It is always better in android to do any IO work on a background thread.
And that includes MediaPlayer . but in MediaPlayer case you already have prepareAsync() method to prepare the MediaPlayer in the background for you.
A good way to do that is like this:
package com.radiomiriam;
import java.io.IOException;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Toast;
public class Main extends Activity implements OnPreparedListener{
public String url = "http://69.64.48.96:9880";
public MediaPlayer player = new MediaPlayer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void stop(){
Toast.makeText(getApplicationContext(), "Finalizando...", Toast.LENGTH_SHORT).show();
if(player.isPlaying()){
player.stop();
}
}
public void play(){
if(player.isPlaying()){
Toast.makeText(getApplicationContext(), "J? est? em execuç?o!", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Preparando...", Toast.LENGTH_SHORT).show();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
try {
player.setDataSource(url);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
player.setOnPreparedListener(this);
player.prepareAsync();
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
}
#Override
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.start();
}
public void onClick(View v) {
final int id = v.getId();
switch (id) {
case R.id.btnPlay:
play();
break;
case R.id.btnStop:
stop();
break;
}
}
}
Also it is always a good practice to read the documentations, so here is a link to MediaPlayer API : MediaPlayer

MediaPlayer Android

I want to use MediaPlayer android, using this code, but I get an error, there's a way to fix this code, or can anyone bring me a better example for this?
try {

player.setDataSource("/LFP/res/raw/Allen.mp3");
player.prepare();
player.start();

This worked fine for me.Hope it works for you also.

use
mediaplayer.prepareAsync()
and
mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
instead it

Here I am keeping my audio file in asset. Following code works,
MediaPlayer mp= new MediaPlayer();
AssetFileDescriptor afd = null;
try {
afd =getActivity().getBaseContext().getAssets().openFd("myAudio.mp3");
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
mp.prepare();
mp.start();
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
} catch (IOException e) {
e.printStackTrace();
}
