My app needs to implement audio capture function .
i have followed several tutorials and google guides . so i have made the code below.
it works fine until the second attempt. when i capture my voice once, it 's able to reply what i have said.
in the second attempt, when i think it had to over write the file created, the app crashes. probably i ignore some methods.
could you help me ?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inizializzaView();
Media();
SetListner();
}
public void inizializzaView(){

Ascolta.setOnClickListener(new View.OnClickListener() {

public void Media(){

i've solved !!!.
the code needs to be implemented .
public void start(View view){
try {
Media();// this creates a new object whenever you capture new voice.
media.prepare();
media.start();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Registra.setEnabled(false);
Stop.setEnabled(true);
Toast.makeText(getApplicationContext(), "Stai registrando Burlone !!!", Toast.LENGTH_LONG).show();
}
public void stop(View view){
media.stop();
media.release();
media = null;
Stop.setEnabled(false);
Registra.setEnabled(true);
Toast.makeText(getApplicationContext(), "Registrazione Terminata",
Toast.LENGTH_LONG).show();

I'm in the process of building a prototype for a project. I want to be able to stream music from my website to the app.
Here is what I have so far. Trying it with an m3u because I honestly have no idea what else to use for this.
Button buttonPlay;
Button buttonStop;
MediaPlayer mPlayer;
String url = "http://www.*******.com/*****/files.m3u";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonPlay = (Button) findViewById(R.id.play);
buttonPlay.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Argument", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Security ", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Statement", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
try {
mPlayer.prepare();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare Illegal State", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare IO", Toast.LENGTH_LONG).show();
}
mPlayer.start();
}
});
buttonStop = (Button) findViewById(R.id.stop);
buttonStop.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
if(mPlayer!=null && mPlayer.isPlaying()){
mPlayer.stop();
}
}
});
Them problem is it throws IOexception after prepare. Now I read somewhere you have to download m3u files and then read them line by line. If that is the case, is there a better way? I'm attempting to make sort of a radio app for testing purposes that will play songs at random, not in order, so I don't want to hard code them MP3 files,
you cant just prepare a stream because it needs to download asynchronously. you will need to do this
Button buttonPlay;
Button buttonStop;
MediaPlayer mPlayer;
String url = "http://www.*******.com/*****/files.m3u";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonPlay = (Button) findViewById(R.id.play);
buttonPlay.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Argument", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Security ", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Illegal Statement", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
try {
mPlayer.prepareAsync();
mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mPlayer.start();
}
};);
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare Illegal State", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly! Prepare IO", Toast.LENGTH_LONG).show();
}
}
});
buttonStop = (Button) findViewById(R.id.stop);
buttonStop.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub

I've tried a lot of code but did not receive an answer,
This code reads the file from the memory, but it is not the case for seekbar

I need help/pointer to doc/sample code on how to load multiple audio files from a specific folder on the SD card and have it play a random file back(i think i can figure out the last step if i could just figure out how to load multiple files).

Memory is extremely limited on mobile devices, so you wouldn't want to load songs you're not going to play. So what you should do is find all of the audio files in that folder, and then choose one and THEN load and play it.
You just need to stop the current player and create a new instance.
MediaPlayer player = MediaPlayer.create(this, Uri.parse("Path/To/Media"));
player.start();
// change track
player.stop();
player = MediaPlayer.create(this, Uri.parse("New/Path/To/Media"));
player.start();
