I am trying to play a sound file on the click of a button. The sound is just 1 sec long. It plays well the first few times I click the button, but after a while it gives a NullPointerException. Here's the code:
button[i].setOnClickListener(new OnClickListener() {
public void onClick(View view) {
mp = MediaPlayer.create(Test.this, R.raw.mysound);
mp.start();
}
});
And here's the exception:
07-29 23:07:27.690: ERROR/AndroidRuntime(10542): Uncaught handler: thread main exiting due to uncaught exception
07-29 23:07:27.710: ERROR/AndroidRuntime(10542): java.lang.NullPointerException
07-29 23:07:27.710: ERROR/AndroidRuntime(10542): at com.example.mypackage.Test$3.onClick(Test.java:270)
Thanks Chris

Thanks you for your answers! Appreciate it!
ReplyDeleteHere's how I finally managed to get it work:
button[i].setOnClickListener(new OnClickListener() {
public void onClick(View view) {
mp = MediaPlayer.create(Test.this, R.raw.mysound);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.release();
}
});
}
});
It might solve your problem,
ReplyDeletebutton[i].setOnClickListener(new OnClickListener() {
public void onClick(View view) {
new Thread(){
public void run(){
mp = MediaPlayer.create(Test.this, R.raw.mysound);
mp.start();
}
}.start();
}
});
If still your issue not solved then try this as it help me.
ReplyDeletepublic void playSound(int resources){
try{
boolean mStartPlaying = true;
MediaPlayer mPlayer=null;
if (mStartPlaying==true){
mPlayer = new MediaPlayer();
Uri uri = Uri.parse("android.resource://YOUR_PACKAGENAME/" + resources);
mPlayer.setDataSource(getApplicationContext(),uri);
mPlayer.prepare();
mPlayer.start();
}
else{
mPlayer.release();
mPlayer = null;
}
mStartPlaying = !mStartPlaying;
}
catch (IOException e){
Log.e(LOG_TAG, "prepare() failed");
}
// MediaPlayer mp = MediaPlayer.create(SpyMainActivity.this, resources);
// mp.start();
}
Enjoy. :)
