This is the most important part in the code provided in the original post    Button one    Button  this findViewById R id button1   final MediaPlayer mp   MediaPlayer create this  R raw soho   one setOnClickListener new OnClickListener         public void onClick View v            mp start                To explain it step by step   Button one    Button  this findViewById R id button1     First is the initialization of the button to be used in playing the sound  We use the Activity s findViewById  passing the Id we assigned to it  in this example s case  R id button1   to get the button that we need  We cast it as a Button so that it is easy to assign it to the variable one that we are initializing  Explaining more of how this works is out of scope for this answer  This gives a brief insight on how it works   final MediaPlayer mp   MediaPlayer create this  R raw soho     This is how to initialize a MediaPlayer  The MediaPlayer follows the Static Factory Method Design Pattern  To get an instance  we call its create   method and pass it the context and the resource Id of the sound we want to play  in this case R raw soho  We declare it as final  Jon Skeet provided a great explanation on why we do so here    one setOnClickListener new OnClickListener         public void onClick View v              code             Finally  we set what our previously initialized button will do  Play a sound on button click  To do this  we set the OnClickListener of our button one  Inside is only one method  onClick   which contains what instructions the button should do on click   public void onClick View v        mp start        To play the sound  we call MediaPlayer s start   method  This method starts the playback of the sound   There  you can now play a sound on button click in Android     Bonus part   As noted in the comment belowThanks Langusten Gustel   and as recommended in the Android Developer Reference  it is important to call the release   method to free up resources that will no longer be used  Usually  this is done once the sound to be played has completed playing  To do so  we add an OnCompletionListener to our mp like so   mp setOnCompletionListener new MediaPlayer OnCompletionListener         public void onCompletion MediaPlayer mp              code             Inside the onCompletion method  we release it like so   public void onCompletion MediaPlayer mp        mp release        There are obviously better ways of implementing this  For example  you can make the MediaPlayer a class variable and handle its lifecycle along with the lifecycle of the Fragment or Activity that uses it  However  this is a topic for another question  To keep the scope of this answer small  I wrote it just to illustrate how to play a sound on button click in Android     Original Post  First  You should put your statements inside a block  and in this case the onCreate method   Second  You initialized the button as variable one  then you used a variable zero and set its onClickListener to an incomplete onClickListener  Use the variable one for the setOnClickListener   Third  put the logic to play the sound inside the onClick   In summary   import android app Activity  import android media MediaPlayer  import android os Bundle  import android view Menu  import android view View  import android view View OnClickListener  import android widget Button   public class BasicScreenActivity extends Activity        Override     protected void onCreate Bundle savedInstanceState                    super onCreate savedInstanceState           setContentView R layout activity basic screen            Button one    Button this findViewById R id button1           final MediaPlayer mp   MediaPlayer create this  R raw soho           one setOnClickListener new OnClickListener                 public void onClick View v                    mp start

The audio must be placed in the raw folder  if it doesn t exists  create one  The raw folder must be inside the res folder The name mustn t have any - or special characters in it    On your activity  you need to have a object MediaPlayer  inside the onCreate method or the onclick method  you have to initialize the MediaPlayer  like MediaPlayer create this  R raw name of your audio file   then your audio file ir ready to be played with the call for start    in your case  since you want it to be placed in a button  you ll have to put it inside the onClick method   Example   private Button myButton  private MediaPlayer mp   Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout myactivity           mp   MediaPlayer create this  R raw gunshot            myButton setOnClickListener new View OnClickListener                  Override             public void onClick View v                    mp start

An edge case   Above every answer is almost correct but I was stuck in an edge case  If any user randomly clicks the button multiple times within a few seconds then after playing some sound it doesn t respond anymore  Reason  Initialize Mediaplayer object is very expensive  It also deals with resources  audio file  so it takes some time for it  When users randomly initialize and calling a method of MediaPlayer s methods like start    stop    release    etc can cause IllegalStateException which I faced  Solution  Thanks caw for his suggestion in the comment about Android-Audio  It has just a simple two java classes  MusicManager java  SoundManager java   You can use MusicManager java if you want to play one-off sound files - MusicManager getInstance   play MyActivity this  R raw my sound    You can use SoundManager java if you want to play multiple sounds frequently and fast - class MyActivity extends Activity        private SoundManager mSoundManager        Override     protected void onResume             super onResume             int maxSimultaneousStreams   3          mSoundManager   new SoundManager this  maxSimultaneousStreams           mSoundManager start            mSoundManager load R raw my sound 1           mSoundManager load R raw my sound 2           mSoundManager load R raw my sound 3              private void playSomeSound             if  mSoundManager    null                mSoundManager play R raw my sound 2                         Override     protected void onPause             super onPause             if  mSoundManager    null                mSoundManager cancel                mSoundManager   null

The best way to do this is here i found after searching for one issue after other in the LogCat  MediaPlayer mp  mp   MediaPlayer create context  R raw sound one   mp setOnCompletionListener new OnCompletionListener          Override     public void onCompletion MediaPlayer mp               TODO Auto-generated method stub         mp reset            mp release            mp null            mp start      Not releasing the Media player gives you this error in LogCat      Android  MediaPlayer finalized without being released   Not resetting the Media player gives you this error in LogCat      Android  mediaplayer went away with unhandled events   So play safe and simple code to use media player   To play more than one sounds in same Activity Fragment simply change the resID while creating new Media player like  mp   MediaPlayer create context  R raw sound two     and play it    Have fun

All these solutions  sound  nice and reasonable but there is one big downside  What happens if your customer downloads your application and repeatedly presses your button   Your MediaPlayer will sometimes fail to play your sound if you click the button to many times   I ran into this performance problem with the MediaPlayer class a few days ago   Is the MediaPlayer class save to use  Not always  If you have short sounds it is better to use the SoundPool class   A save and efficient solution is the SoundPool class which offers great features and increases the performance of you application   SoundPool is not as easy to use as the MediaPlayer class but has some great benefits when it comes to performance and reliability   Follow this link and learn how to use the SoundPool class in you application   https   developer android com reference android media SoundPool  Youtube  Save Solution
