OnClick Button Sound link with an ImageView

I'm trying to learn to program a simple app in (Android Studio), in this app I have 10 images which I programmed them with ImageSwitcher to go next or previous, Now I want to have a button which plays my 10 audios according to each image. Example when the Image I1 is shown and user presses PLAY button then Audio A1 plays, and the same for the rest I2=A2, I3=A3 and ...
Any help would be great and is appreciated.
with best regards

First you need to add your audio files in the raw folder. Then create an array with reference of image array put names of audio accordingly
public class MainActivity extends AppCompatActivity {
Context context = this;
MediaPlayer mp;
int audioList[] = [R.raw.audio1, R.raw.audio2........]
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
Button b = (Button) findViewById(R.id.Button);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp = MediaPlayer.create(context, audioList[currentIndex]);
try {
if (mp.isPlaying()) {
mp.stop();
mp.release();
mp = MediaPlayer.create(context, audioList[currentIndex]);
} mp.start();
} catch(Exception e) { e.printStackTrace(); }
}
});
}
}
Hope this works for you.
Happy Coding

Android Studio- Media Player doesn't play sound On Genymotion?

I am trying to build a small app which plays a sound when we click on the button. But I am not able to play the sound. Don't know what the problem is. Please help me on this. Below is the code.
public class MainActivity extends AppCompatActivity {
private Button button;
private MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(getApplicationContext(),R.raw.song);
button = (Button)findViewById(R.id.mediaButtonId);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer.start();
}
});
}
}
Note:-Sorry guys,I thought that the problem is with my code but the app is running perfectly fine on my phone,so its the problem with my genymotion emulator.Can anyone please suggest me the solution for this.By the way,I am using Mac OSX.

The MediaPlayer has its own lifecycle. You can't just create the instance and then start to play. First you have to prepare it and then play it.
You can prepare your mediaplayer either sync or asynchronously.
Something along the lines of:
MediaPlayer mediaPlayer= new MediaPlayer();
mediaPlayer=MediaPlayer.create(getApplicationContext(),R.raw.song);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();
Or, if you want to do it synchronously
MediaPlayer mediaPlayer= new MediaPlayer();
mediaPlayer=MediaPlayer.create(getApplicationContext(),R.raw.song);
try {
mediaPlayer.prepare();
} catch (IOException e){
}
mediaPlayer.start();
Just make sure you prepare it before you play it.
Media Player lifecycle: https://developer.android.com/reference/android/media/MediaPlayer.html

You need to make sure the media player is ready before you can play it, so you set the onPreparedListener to handle this for you, like so:
MediaPlayer mp = new MediaPlayer();
mp = MediaPlayer.create(getApplicationContext(),R.raw.song);
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mp.start();
}
});
button = (Button)findViewById(R.id.mediaButtonId);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.prepareAsync();
}
});
There will be a slight delay from when you press the button to the sound playing this way. Another way to do it could be to disable the button until the media player has prepared and then in the onclick of the button you could just call mp.start(); when the button has been enabled.

Media Player start stop start

I am making a new android sound application. I made a clickable button to play sound when I click on it. But I also want it to stop playing sound when I click for the second time. That part works fine now here is the problem, when I click again on button to play sound again, it doesn't play it, Media player is completely stopped. I was looking on forums but I can't seem to find an answer that could help me.
Here is my Activity:
MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.prvi);
final MediaPlayer mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
final MediaPlayer mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);
Button dugme = (Button) findViewById(R.id.dugme);
dugme.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
mpButtonClick1.reset();
}
else {
mpButtonClick1.start();
}
}
});
When I try to write mpButtonClick1.prepare(); I get error Unhandled Exception Type IOE exception

Try to use pause instead of stop.
Reason: if you pause the MediaPlayer, then you can resume it later. However, if you use stop, almost any other method won't work and you will have to prepare the MediaPlayer again (or create a new one).
More info: here and here
PS: don't forget to release the memory when you finish using the resources.

Try this:
You should use only one mediaplayer object
public class PlayaudioActivity extends Activity {
private MediaPlayer mp;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
Button b2 = (Button) findViewById(R.id.button2);
final TextView t = (TextView) findViewById(R.id.textView1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
mp.start();
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
mp.start();
}
});
}
private void stopPlaying() {
if (mp != null) {
mp.stop();
mp.release();
mp = null;
}
}
}

Change your class with below code:
remove reset();.
init well all components:
MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.prvi);
mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);
Button dugme = (Button) findViewById(R.id.dugme);
dugme.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
}
else {
mpButtonClick1.start();
}
}
});

You're calling mpButtonClick1.reset() after mpButtonClick1.stop() - don't do that:
if (mpButtonClick1.isPlaying()) {
mpButtonClick1.stop();
mpButtonClick1.reset(); //<--------- calling reset(), remove this line
}
The docs for reset() say:
Resets the MediaPlayer to its uninitialized state. After calling this method, you will have to initialize it again by setting the data source and calling prepare().
Remove mpButtonClick1.reset() and it should work.
Keep in mind that MediaPlayer works as a state machine, which means that if you call methods in the wrong order, you'll get problems. Please read about MediaPlayer here and here.

Hey please use following
for stop -> media player
mp.seekTo(0);
mp.pause();
again for start just call
mp.start();

In my experience when I need to play multiple times and I may need to stop one play to start another play, (like in the case of multiple buttons), I just create another player, making sure that I release the resources for the previous one. To stop just use
mediaPlayer.stop();
But for play use something like this (adapt the logging to your specific needs) to create/recreate your player:
private boolean createMediaPlayer()
{
if (mediaPlayer!=null)
{
if(mediaPlayer.isPlaying())
{
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer=null;
}
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setVolume(1f, 1f);
try
{
mediaPlayer.setAudioStreamType(Interop.PRIMARY_STREAM);
mediaPlayer.setDataSource(m_soundFile);
mediaPlayer.prepare();
return true;
// Interop.logDebug(TAG + "-loadAudio: SUCCESS" + m_soundFile);
} catch (Exception e)
{
Interop.logError(TAG + "-LoadAudio for Clic Sound: audioPlayer prepare failed for current file: " + m_soundFile);
Interop.logError(TAG + "-Exception: " , e);
return false;
}
}
and than use
if (createMediaPlayer())
mediaPlayer.start();
this will ensure proper release of the resources used by the media player.

A simple solution is to Use pause instead of stop and the seek to the beginning of the song.

I know that this question is quite old but recently while learning Android, I also got stuck at this point and found a very simple solution which I'd like to share with everyone.
Instead of trying to stop or reset the media, you can just seek back to the starting position.
mediaPlayer.seekTo(0);
For reference, I am also posting my code below:
public class MainActivity extends AppCompatActivity {
MediaPlayer mp;
public void play(View view) {
mp.start();
}
public void pause(View view) {
mp.pause();
}
public void stop(View view) {
// this seeks to the beginning of the file
mp.seekTo(0);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(this, R.raw.sample_audio);
}
}

Stop audio playback

I am new to Android programming and i have a problem that i can not solve without your help...Please, give me a hand... ;-)
When i start playing my audio file, i can not stop it. Instead, I am quitting the application.
I play audio file with this code:
public class Word1Audio extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.word1video);
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.lige);
mediaPlayer.start();
}
}
HOWEVER, when i try to stop it when the back button is pressed by this piece of code
#Override
public void onBackPressed() {
// do something on back.
return;
}
my applications closes down and audio continues to play...
Do you have an idea why the application closes down? And how can i just stop the music and go back to the previous page...??
Thank you for your time and help... :-)

you could try
MediaPlayer mediaPlayer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.word1video);
mediaPlayer = MediaPlayer.create(this, R.raw.lige);
mediaPlayer.start();
}
#Override
public void onBackPressed() {
if( mediaPlayer.isPlaying() ) {
mediaPlayer.stop();
}
super.onBackPressed();
}

MediaPlayer with looped audio not stopping on app onPause

I've written an app which has some looped audio playing in the background (via MediaPlayer).
When the app is ended (e.g. via use hitting back button) I call onPause and try to close the mediaplayer:-
#Override
public void onPause(){
super.onPause();
if (mp != null) {
mp.stop();
mp.release();
mp = null;
}
However, it seems that by the time onPause is called the mediaplayer (mp) object is always null, even though the looped audio is still being played. So it can't be stopped.
The mediaplayer is declared at the top of the class and initiated in onCreate:-
public MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MediaPlayer mp = MediaPlayer.create(this, R.raw.longstream);
mp.setVolume(0.2f, 0.2f);
mp.setLooping(true);
mp.start();
}
So, am I declaring the mediaplayer incorrectly? Or how do I get it to persist to be closed properly? And how come it is still playing if the object is null?
Any ideas gratefully received...

When you declare the MediaPlayer in your onCreate, it shadows the member mp, so all of the methods are performed on the object declared in onCreate, not on the class member:
MediaPlayer mp = MediaPlayer.create(this, R.raw.longstream);
Change it to
public MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mp = MediaPlayer.create(this, R.raw.longstream);
mp.setVolume(0.2f, 0.2f);
mp.setLooping(true);
mp.start();
}

This is your code modified, it should work this way: the problem came from the fact that you declare mp as an attribute of your class, but you then instantiate it locally in your onCreate method.
public MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mp = MediaPlayer.create(this, R.raw.longstream);
mp.setVolume(0.2f, 0.2f);
mp.setLooping(true);
mp.start();
}
