Android SoundBoard Crash when Activity resumed - android

Hi there I have built a soundboard for a character of mine called Aussie Bloke - the soundboard contains 30 buttons and 30 mediaplayers. I originally used one mediaplayer for all buttons but eventually the sounds would stop playing after about 20 random presses. So I decided on using seperate mediaplayer objects for each sound as used in the original soundboard template I used. This worked fine you could press buttons all day and get sounds working properly ..but the problem I have is that when the activity is sent to the background and brought back again even after a few seconds the app crashes when you press a button..I tried creating an onResume method to prepare all the players but this just made the app crash right from the start..sorry I am very new to coding and app building so there may be an obvious solution I have overlooked or been completely unaware of.

You need to implement onResume() method in your activity and recreate there your mediaplayer objects:
public void onResume() {
super.onResume();
// ...
beer1 = MediaPlayer.create(this, R.raw.beer1);
beer2 = MediaPlayer.create(this, R.raw.beer2);
beer3 = MediaPlayer.create(this, R.raw.beer3);
// ...
}

AudioRecorder App crashes when I record a second time

My app breaks down when I attempt to record a second a time when I hit the stop button. I went through this code several times. I can't find the problem. I'm not sure if its my MediaRecorder or my MediaPlayer. It works the first time around. But not the second time. can anyone find the problem.

Streaming audio from website to app

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
if(mPlayer!=null && mPlayer.isPlaying()){
mPlayer.stop();

Above is all code in class PlayMusicActivity of me... And thanks for helping me
Call the prepareAsync() method from the playsong method, as it will starting buffering the audio immediately. When enough audio has buffered the onPrepared method will be called and audio will play
private void playSong(String urlData) {
btnPlay = (ImageButton) findViewById(R.id.btnPlay);
seekBar = (SeekBar) findViewById(R.id.seekBar);
btnPlay.setOnClickListener(this);
seekBar.setMax(99);
seekBar.setOnTouchListener(this);
mPlay = new MediaPlayer();
mPlay.setAudioStreamType(AudioManager.STREAM_MUSIC);
mPlay.setOnBufferingUpdateListener(this);
mPlay.setOnCompletionListener(this);
try {
mPlay.setDataSource(urlData);
mPlay.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

MediaPlayer error android

I have an activity which has a series of buttons which when pressed should play an audio file. I have been trying to implement this using MediaPlayer however I cant get it to work.
Here is the code I have been trying:
final MediaPlayer mp = new MediaPlayer();
Button ger1play = (Button) findViewById(R.id.ger1play);ger1play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.setDataSource(this, R.raw.greet_1);
mp.prepare();
mp.start();
}
});
The setDateSource method doesnt seem to work, can anyone tell me where I am going wrong?
I would like to then set the mediaPlayer to the relevant audio file based on which button is pressed, is this possible?
Updated
final MediaPlayer mp = new MediaPlayer();
Button ger1play = (Button) findViewById(R.id.ger1play);ger1play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
Uri myUri = Uri.parse(R.raw.greet_1);
mp.setDataSource(GreetingsLesson.this, R.raw.greet_1);
mp.prepare();
mp.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
try this:
final MediaPlayer mp = new MediaPlayer();
Button ger1play = (Button) findViewById(R.id.ger1play);ger1play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
mp.setDataSource(CurrentActivity.this, R.raw.greet_1);
mp.prepare();
mp.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
Ifyou want to send the media player object with one of the files fromapplication raw resources or from application assets files you can dothat as follows:
try {
AssetFileDescriptor fd = getResources().openRawResouceFd(R.raw.greet_1);
mp.setDataSource(fd.getFileDescriptor(), fd.getStartOffset(), fd.getLength());
mp.start();
fd.close();
} catch (IllegalArgumentException e) {
// handle exception
} catch (IllegalStateException e) {
// handle exception
} catch (IOException e) {
// handle exception
}
Why not just use
mp = MediaPlayer.create(this, R.raw.greet_1);
Then you don't need the prepare or start.
Are you running this in an emulator? If so check your AVD manager has under hardware, the property "Audio playback support | yes" added
