Toggle between earphone and speakerphone not working, with MediaPlayer and AudioManager - android

I'm using MediaPlayer to play audio via an AsyncTask, and using AudioManager to set the stream. On a specific button press, I call AudioManager's setSpeakerPhoneOn() to toggle, but it doesn't switch to ear speaker. My audio always blasts through the main speaker.
I tried these solutions (as is apparent in the code below), but none worked:
Switching between earpiece and speakerphone on button
press
Audiomanager Speaker not
working
Here's my code for initializing the AudioManager in onViewCreated:
try {
audioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
audioManager.setSpeakerphoneOn(loudOn);
// loudOn is defined globally, and initialized to false
}
This is the audio playing function which uses AsyncTask:
static private void playCall(final Context context, final String[] contactParts)
{
final MediaPlayer mediaPlayer = new MediaPlayer();
new AsyncTask<Void,Void,Boolean>() {
#Override
protected Boolean doInBackground(Void... voids) {
try {
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.reset();
mp.release();
}
});
int audioFile_R_id = //get audio file id
try {
AssetFileDescriptor afd = context.getResources().openRawResourceFd(audioFile_R_id);
if (afd == null) return false;
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mediaPlayer.setAudioAttributes(new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_VOICE_COMMUNICATION)
.setContentType(AudioAttributes.CONTENT_TYPE_SPEECH)
.build());
} else {
//deprecated in API 26
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
mediaPlayer.prepare();
return true;
}
catch (Resources.NotFoundException rnf)
{
rnf.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
return false;
}
#Override
protected void onPostExecute(Boolean prepared) {
if (prepared) {
mediaPlayer.start();
}
}
}.execute();
}
And this is the button code that attempts to toggle:
loudFAB.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
loudOn = !loudOn;
audioManager.setSpeakerphoneOn(loudOn);
}
});

Change the AudioManager
try {
audioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setSpeakerphoneOn(loudOn);
// loudOn is defined globally, and initialized to false
}

Playing sound on the alarm channel on android

I have done a lot of googling but other's solutions are not working for me.
My goal is to play a sound on demand on the alarm channel.
(So the sound volume is adjusted by the alarm volume setting)
from this thread I build the following code
mediaPlayerScan = MediaPlayer.create(getContext(), R.raw.scan_beep);
if (Build.VERSION.SDK_INT >= 21) {
mediaPlayerScan.setAudioAttributes(new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_ALARM)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build());
} else {
mediaPlayerScan.setAudioStreamType(AudioManager.STREAM_ALARM);
}
It still plays on the music channel.
(IE volume is adjusted in music setting not alarm)
My intuition is that i'm missing a permission or something, but I haven't found such a permission.
I'm testing on a Google Pixel 1
Thanks,
Nathan
Edit:
Thanks to #jeffery-blattman the following code works for me
mediaPlayerScan = new MediaPlayer();
try {
mediaPlayerScan.setDataSource(getContext(),
Uri.parse(getString(R.string.res_path) + R.raw.scan_beep));
if (Build.VERSION.SDK_INT >= 21) {
mediaPlayerScan.setAudioAttributes(new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_ALARM)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build());
} else {
mediaPlayerScan.setAudioStreamType(AudioManager.STREAM_ALARM);
}
mediaPlayerScan.prepare();
} catch (IOException e) {
e.printStackTrace();
}
The problem is that create() puts the MediaPlayer in a state where it won't accept the attributes (it calls prepare() for you). You need to use the more verbose mechanism of creating the player.
final MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(...);
AudioAttributes attrs = new AudioAttributes.Builder().setUsage(usage).build();
mediaPlayer.setAudioAttributes(attrs);
new AsyncTask<Void,Void,Boolean>() {
#Override
protected Boolean doInBackground(Void... voids) {
try {
mediaPlayer.prepare();
return true;
} catch (IOException e) {
e.printStackTrace();
}
return false;
}
#Override
protected void onPostExecute(Boolean prepared) {
if (prepared) {
mediaPlayer.start();
}
}
}.execute();
I upvoted Jeffrey Blattman's answer above, but here is the full code that shows how to use setDataSource with an audio file that you put into your app resources (raw). Also a couple of other things I picked up in my travels...
static public void playAlarmSound () {
final MediaPlayer mediaPlayer = new MediaPlayer();
new AsyncTask<Void, Void, Boolean>() {
#Override
protected Boolean doInBackground(Void... voids) {
try {
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mediaPlayer.reset();
mediaPlayer.release();
}
});
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}
});
AssetFileDescriptor afd = getContext().getResources().openRawResourceFd(R.raw.nameofyourresource);
if (afd == null) return false;
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
afd.close();
if (Build.VERSION.SDK_INT >= 21) {
mediaPlayer.setAudioAttributes(new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_ALARM)
.setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
.build());
} else {
mediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
}
mediaPlayer.setVolume(1.0f, 1.0f);
mediaPlayer.prepare();
return true;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
}.execute();
}

Play mp3 files one after the other with little delay with more elegant code?

I need to play multiple (correct :2 ) mp3 files loaded from my assets when a button is clicked. If the button is again clicked 2 new songs should be played and the old ones should be stopped immidiatelly.The process is on going...
At the moment I have achieved this by stupidly creating 2 mediaPlayer instances in 2 separate methods that basically have the same body .
The caller is an onTouch method and ,within it, first I call method 1 ,then sleep for 2 secs ,then call method 2. I m sure there must be a way for this to be more elegant code? For example I have implemented some listeners that are just sitting there (Actually tried to make this work but totally screwed up with Illegal States all over the place ). Ideally I would like to use 1 MediaPlayer and one method for playing every sound in my app.
int carouzelIndex = 0
#Override
public boolean onTouch(MotionEvent e, int scaledX, int scaledY) {
...
if (e.getAction() == MotionEvent.ACTION_UP) {
carouzelIndex++;
Assets.playMusic1("music1.ogg",false);
Thread thread = new Thread(){
public void run(){
try {
Thread.sleep(1500);
} catch (InterruptedException e) {
e.printStackTrace();
}
Assets.playMusic2("music2.ogg",false);
}
}
}
}
Now my player methods 1 and 2 (playMusic1() and playMusic2() )are the same. Both are instansiating different MediaPlayers and for the shake of simplicity I write just one copy in the post
Public class Assets
MediaPlayer mediaPlayer;
public static void playMusic(String filename, boolean looping) {
AssetFileDescriptor afd = null;
Log.d("Assets", "playing music");
if (mediaPlayer == null) {
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setLooping(looping);
}
try {
if (mediaPlayer != null) {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setLooping(looping);
}
afd = GameMainActivity.assets.openFd(filename);
mediaPlayer.setDataSource(afd.getFileDescriptor(),
afd.getStartOffset(), afd.getLength());
afd.close();
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
if (!mp.isPlaying())
mp.start();
}
});
mediaPlayer.setOnErrorListener(new OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
return false;
}
});
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mediaPlayerIsFinished = true;
mp.reset();
}
});
mediaPlayer.setOnInfoListener(new OnInfoListener() {
#Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
// TODO Auto-generated method stub
return false;
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
For immediate playback you need two MediaPlayer set up and chained together via OnCompletionListener
You can do it like this:
Note that I also deleted some unnecessary overrides, you might add them again if you need them.
Public class Assets{
MediaPlayer mediaPlayer;
MediaPlayer mediaPlayer2;
boolean mediaplayer2prepared = false;
boolean mediaplayer1finished = false;
public static void playMusic(String filename, boolean looping, String filename2, boolean looping2) {
AssetFileDescriptor afd = null;
Log.d("Assets", "playing music");
if (mediaPlayer == null) {
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setLooping(looping);
mediaplayer1finished = false;
}
if (mediaPlayer2 == null) {
mediaPlayer2 = new MediaPlayer();
mediaPlayer2.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer2.setLooping(looping);
mediaplayer2prepared = false;
}
try {
if (mediaPlayer != null) {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setLooping(looping);
mediaplayer1finished = false;
}
if (mediaPlayer2 != null) {
mediaPlayer2.stop();
mediaPlayer2.release();
mediaPlayer2 = new MediaPlayer();
mediaplayer2prepared = false;
mediaPlayer2.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer2.setLooping(looping);
}
afd = GameMainActivity.assets.openFd(filename);
mediaPlayer.setDataSource(afd.getFileDescriptor(),
afd.getStartOffset(), afd.getLength());
afd.close();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
if (!mp.isPlaying())
mp.start();
}
});
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mediaPlayerIsFinished = true;
mp.reset();
if(mediaplayer2prepared)
mediaplayer2.start();
mediaplayer1finished = true;
}
});
mediaPlayer.prepareAsync();
afd2 = GameMainActivity.assets.openFd(filename2);
mediaPlayer2.setDataSource(afd2.getFileDescriptor(),
afd2.getStartOffset(), afd2.getLength());
afd2.close();
mediaPlayer2.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayerIsFinished = true;
mp.reset();
mediaplayer2prepared = true;
if(mediaplayer1finished && !mp.isPlaying()){
mp.start();
}
}
});
mediaPlayer2.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mediaPlayerIsFinished = true;
mp.reset();
}
});
mediaPlayer2.prepareAsync();
} catch (Exception e) {
e.printStackTrace();
}
}
}
To start both mediaplayers in succession simply do Assets.playMusic("music1.ogg",false, "music2.ogg",false);
You can try something like this. Use a single mediaplayer in a single thread. It is an asynchronous operation so it will go on also if the thread is paused. I think it would work.
private Thread t = null;
private MediaPlayer mediaPlayer;
...
Button b=findViewById(R.id.yourButtonId);
b.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
//if button had previously clicked stop audio reproduction
if(mediaPlayer.isPlaying()) mediaPlayer.stop();
if(t.isAlive()) t.stop();
String[] files;
//Here you have to set your filenames in the array
...
...
//Now play that audio
playMusic(files, false);
}
});
...
protected static void playMusic(String[] files, boolean looping){
AssetFileDescriptor afd = null;
Log.e("Assets", "Playing music");
t=new Thread(){
#Override
public void run(){
//Initialize mediaPlayer
for(String filename:files){
mediaPlayer=new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setLooping(looping);
afd = GameMainAcivity.assets.openFd(filename);
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(),afd.getLength());
afd.close();
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer mp){
if(!mp.isPlaying()) mp.start();
}
});
//while audio is playing wait in this position
while(mediaPlayer.isPlaying()){
this.wait(100);
}
//now loop can restart with the other filename that has
//to be reproduced
}
}
};
t.start();
}

adding mutiple audio file in android

i'm adding multiple audio files using
try {
MediaPlayer mp = MediaPlayer.create(context, R.raw.play);
audioArr[0] = mp;
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
and releasing media in a function as
for (MediaPlayer media : audioList) {
if (media != null) {
if(media.isPlaying())
media.stop();
media.release();
media = null;
}
}
stil i'm not able to play multiple audio file in my application,first time playing with audio,so kindly guide
Try this :
void addSongs()
{
File songs = new File(sdPath); //sdPath is the path of your audio files
if(songs.listFiles(new SongFilter()).length > 0)
{
for(File file : songs.listFiles(new SongFilter()))
{
vector.add(file.getName());
}
arrayAdapter.setNotifyOnChange(true); //arrayAdapter Array Adapter
songList.setAdapter(arrayAdapter); //songList is a ListView
}
}
SongFilter Class like this :
class SongFilter implements FilenameFilter
{
public boolean accept(File dir, String filename)
{
return (filename.endsWith(".mp3"));
}
}
buttonSound.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// play another sound here.do your stuff whatever you want to do
mp.stop();
}
});
public class AudioActivity extends Activity implements MediaPlayer.OnCompletionListener {
int [] songs;
MediaPlayer mediaPlayer;
int current_index = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {##}
private void start(){
songs= new int[] {R.raw.s1,R.raw.s2,R.raw.s3,R.raw.s4};
mediaPlayer = MediaPlayer.create(this, songs[0]);
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.start();
}
#Override
public void onCompletion(MediaPlayer mp) {
**// This is the completion listener registered with mediaplayer instance.**
playNextSong();
}
private void playNextSong()
{
current_index = (current_index +1)% songs.length;
AssetFileDescriptor afd = this.getResources().openRawResourceFd(songs[current_index]);
if(current_index!=0){
try
{
mediaPlayer.reset();
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
mediaPlayer.prepare();
mediaPlayer.start();
afd.close();
}
catch (IllegalArgumentException e){}
catch (IllegalStateException e){}

How to correctly change MediaPlayer audio stream type?

I have a simple mp service to play, pause, resume audio. All works fine.
But, last night I have decided to add a feature for user to route audio to ear-piece or speaker and have been battling with mp.setAudioStreamType().
Problem is that I can't change it while service connected and mp created. I don't want to terminate service and/or unbind and rebind as it would require a lot of refactoring
How do I supposed to change AudioStreamType while playing an audio?
Here is my code:
Player service:
public class PService extends Service {
private MediaPlayer mp = new MediaPlayer();
public static final String PLAYING_FINISHED_MSG = "1";
#Override
public void onCreate() {
super.onCreate();
}
#Override
public void onDestroy() {
mp.stop();
mp.release();
}
private void playSong(String file) {
try {
mp.reset();
mp.setDataSource(file);
mp.setAudioStreamType(MYAPP.getAudioStreamType());
mp.prepare();
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer arg0) {
Intent i = new Intent();
i.setAction(MDService.PLAYING_FINISHED_MSG);
sendBroadcast(i);
}
});
toggle route button onclick
currentlyPlayingFile = file;
currentlyPlayingPhone = phone;
lastDurationBeforePause = mpInterface.getCurrentPosition();
if(MYAPP.getAudioStreamType() == AudioManager.STREAM_MUSIC)
{
MYAPP.setAudioStreamType(AudioManager.STREAM_VOICE_CALL);
recording_player_route_button.setImageResource(R.drawable.route_off);
}
else{
MYAPP.setAudioStreamType(AudioManager.STREAM_MUSIC);
recording_player_route_button.setImageResource(R.drawable.route_on);
}
try {
mpInterface.playFile(file);
player_seekbar.setProgress(0);
player_seekbar.setMax(mpInterface.getDuration());
//seekto last millisecond after switching from/to sepaker
if(seekTo>0)
{
mpInterface.seekTo(seekTo);
}
isPauseButtonPressed = false;
handleSeekBarUpdate.postDelayed(handleSeekBarUpdateJob, 1);
} catch (RemoteException e) {
e.printStackTrace();
}
The MODIFY_AUDIO_SETTINGS permission is needed in the Manifest for this to work.
AudioManager am=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
am.setMode(AudioManager.MODE_NORMAL);
MediaPlayer mp=new MediaPlayer();
Uri ringtoneUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
try
{
mp.setDataSource(getApplicationContext(), ringtoneUri);
mp.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
mp.prepare();
mp.start();
}
catch(Exception e)
{
//exception caught in the end zone
}

Sound not working in ICS

I am using Media player to play a sound file. It is working well on 2.2 and 2.3 but not working for ICS 4.0.3, I have checked that mobile is not on silent mode. my code is:
private MediaPlayer mediaPlayer;
private void playSound(int soundType) {
try {
mediaPlayer = MediaPlayer.create(this, R.raw.beep);
if (!mediaPlayer.isPlaying()) {
mediaPlayer.start();
}
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
mediaPlayer.release();
}
});
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
Sound in ICS is played like this :
(i copied it from a previous post, so if theres any weird stuff in there i apologize)
AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
int mSoundID = mSoundPool.load(this, R.raw.sound1, 1);
float lActualVolume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
float lMaxVolume = (float) audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
float lVolume = lActualVolume / lMaxVolume;
// Is the sound loaded already?
if (mSoundIsLoaded) {
mSoundPool.play(mSoundID, lVolume, lVolume, 1, 0, 1f);
}
You will have to put the sound file in your assets/raw directory.
edit: I forgot to mention where the mSoundIsLoaded parameter came from. I set it when my sound has been loaded. I do this in my onCreate method. when the sound is loaded I set the boolean field called mSoundIsLoaded. I do this to prevent NullPointerExceptions when playing the sound the loading of the sound looks like this:
mSoundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
mSoundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
#Override
public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
mSoundIsLoaded = true;
}
});
mSoundID = mSoundPool.load(this, R.raw.sound1, 1);
This is the code i use in my app.. It is working fine in ICS
public void playWelcomeAudio() {
Thread t = new Thread()
{
#Override
public void run() {
AssetFileDescriptor afd = getApplicationContext().getResources().openRawResourceFd(R.raw.welcome);
try {
if(afd!=null)
{
UtilLog.d(TAG, "INIT MEDIA PLAYER");
welcomeAudio = new MediaPlayer();
welcomeAudio.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
welcomeAudio.prepare();
welcomeAudio.start();
}
} catch (Exception e) {
UtilLog.e(TAG, "Audio error", e);
}
}
};
t.start();
}
You can remove the thread. It is not necessory.
