1) I want when I click on back button on the phone to close current
activity and get back to menu and stop Media Player
1) What do you mean by menu? I mean application menu or device menu or notification bar etc.
2) But I get error: Unfortunately Weapons has stopped! upon clicking on

I am trying to get the Image Button to play a sound each time it's clicked. For example, if the sound is playing for few seconds and I press the button again it should start from the beginning. I managed to get the sound working but it's not repeating it. How can I get it to start over?
ImageButton bt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bt = (ImageButton) findViewById(R.id.clickme);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.bird);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();
}
});
}
Try this:
#Override
public void onClick(View v) {
try {
if (mp.isPlaying()) {
mp.stop();
mp.release();
mp = MediaPlayer.create(context, R.raw.bird);
}
mp.start();
} catch(Exception e) {
e.printStackTrace();
}
}
Use MediaPlayer.seekto() to seek to the start of the audio file.
ImageButton bt;
private MediaPlayer mp = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bt = (ImageButton) findViewById(R.id.clickme);
mp = MediaPlayer.create(this, R.raw.bird);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp.isPlaying()) {
mp.seekTo(0);
} else {
mp.start();
}
}
});
}
I used these codes from this reference. They want to click on button to play music and then click again to stop playing. (in their comment they said it was worked for them but hanging for me)
It is work just for first time. I mean for first click the music is playing. for second click the music is stop but for third click the phone emulator show this error:
unfortunately your program has stopped.
This is my code:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
else {
mp.start();
}
}
});
}
In onCreate initialize mp as :
mp = new MediaPlayer();
The error is you are releasing the media player object mp, which destroys the object, call reset method instead of release.
if (mp.isPlaying())
{
mp.stop();
mp.reset();
}
else {
mp = MediaPlayer.create(LegalActivity.this, R.raw.free1);
mp.start();
}
use this below code for play and pause the music:
public MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.btnRain);
//mp = MediaPlayer.create(this, R.raw.rain);
mp = MediaPlayer.create(MainActivity.this, R.raw.rain);
btn.setOnClickListener(new View.OnClickListener() {
#Override
//MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.soundFileName);
// mp.start();
public void onClick(View v) {
if (mp.isPlaying()) {
mp.pause();
}
else {
mp.start();
}
}
});
}
This is an AUDIO activity that works fine and it allows you to upload songs with a spinner.

When i launch app and lock the screen without clicking(playing audio) button and after when i unlock the screen and press the play button i am getting Exception.
public class DemoActivity extends Activity {
MediaPlayer mp;
Button btn;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
mp = MediaPlayer.create(DemoActivity.this,R.raw.mus);
btn = (Button) findViewById(R.id.btnOk);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (btn.getText().toString().equalsIgnoreCase("play")) {
mp.start();
btn.setText("Pause");
} else if (btn.getText().toString().equalsIgnoreCase("pause")) {
mp.pause();
btn.setText("Play");
}
}
});
#Override
public void onPause() {
super.onPause();
if (mp.isPlaying()) {
mp.start();
} else {
mp.release();
}
}
#Override
protected void onRestart() {
try {
if (mp.isPlaying() && mp!=null) {
mp.start();
} else {
mp.release();
}
} catch (IllegalStateException e) {
e.printStackTrace();
}
super.onRestart();
}
#Override

super.onDestroy();
mp.release();
}
}
Here is my code please try to give me a solution.
Thanks in advance
please try call mp.prepare() before every mp.start(). You are getting the error because the mp is not yet ready for your use, and calling start() on that will cause IllegalStateException.

whenever i click back or click home the sound is stop.. how to make the sound is still playing even when i click home or back button.. sorry for my english..
There is a Google sample project about playing music across different Android platforms, like Phone, Pad, Watch, Auto... It can keep music playing even app is exited. Take a deep look at here , and I think you will be inspired a lot.
I have a stop button and a play button. When I click the play button, the audio plays fine and when I press stop, the audio stops. However, if I accidently hit the stop button twice in a row, an IllegalStateException gets thrown and force closes. How can I keep this force close from happening. Essentially what I want is that if someone accidently hits the stop button twice, the program does nothing. Here is the code:
private MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.alphabet);
Button play = (Button) findViewById(R.id.button1);
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
mp = MediaPlayer.create(getBaseContext(), R.raw.e_1100);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
}
});
Button stop = (Button) findViewById(R.id.button2);
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (mp != null && mp.isPlaying()) {
mp.stop();
mp.release();
}
else if (mp.isPlaying() == false) {
// What do I put here???
}
}
});
}
}
try this
if (mediaPlayer != null) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
