I am new here. I was asked by my professor to play other audio while the same video is being played(for example a person doesn't understand English and wants the the app to play french ). I have used video view. One possible method was to mute the present audio and play the french audio stored in my sdcard. but video view supports no muting( i couldn't find one). I read that i have to go for media player instead of video view.
Please help...!! what should i do... Thanks in advance.

if you want to get access to the MediaPlayer of a VideoView you have to call MediaPlayer.OnPreparedListener and MediaPlayer.OnCompletionListener, then you can call setVolume(0f, 0f); function to set the volume to 0.
Do this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
VideoView videoView = (VideoView)this.findViewById(R.id.VVSimpleVideo);
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
videoView.setMediaController(mc);
String _path = "/mnt/sdcard/Movies/video5.mp4";
videoView.setVideoPath(_path);
videoView.setOnPreparedListener(PreparedListener);
videoView.requestFocus();
//Dont start your video here
//videoView.start();
}
MediaPlayer.OnPreparedListener PreparedListener = new MediaPlayer.OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer m) {
try {
if (m.isPlaying()) {
m.stop();
m.release();
m = new MediaPlayer();
}
m.setVolume(0f, 0f);
m.setLooping(false);
m.start();
} catch (Exception e) {
e.printStackTrace();
}
}
};

How can I used to stream files from another application program?
When I play video from main activity it plays and when I quit and go to file explorer and chose my player from custom dialog box and open I have that problem with uriString...

When navigating through your files you can set a clicklistener on a thumbnail. I use this code to fire up a full-screen video editor:
thumbNail.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (pathType.equals("image")) {
<snip>
}
else {
// music file
}
else {
// must be video
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(cmsURL + pathListFull,"video/mp4");
PackageManager packageManager = getActivity().getPackageManager();
List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);
boolean isIntentSafe = activities.size() > 0;
if (isIntentSafe) {
startActivity(intent);
}
else {
Log.d("SHOWFILE", "no intents available");
}
}
}
});

Android playing audio and recordning audio at the same time

How to record audio and playing sound at the same time. Which process is better to implement in background and what to use Thread or AsyncTask? I haved tried playing sound in new thread and recordning on main thread but i have problem that on some devices i get error that the main thread is overload.
Is it better to use native rocordning, because i also need recorded buffer?
Does anybody have any example how to use native recording?

You can use following custom class:-

mp = new MediaPlayer();
System.out.println("2222222222");
} catch (Exception e) {
// TODO: handle exception
System.out.println("exception in audia player====" + e.toString());
}
}
public void onPrepared(MediaPlayer player) {
mp.start();
}
boolean WORKING = true;
public void mediaPlayStart(final Context m_Context) {
try {
mp = new MediaPlayer();
mp.setDataSource(m_Context, Uri.parse(Contants.audioURL_OR_PATH));
mp.prepare();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setLooping(true);
} catch (Exception e) {
// TODO: handle exception
Toast.makeText(m_Context, "Service unavailable this time. Please try again!", Toast.LENGTH_LONG).show();
System.out.println("#####THE EXCEPTION IN THE MEDIA PLAYER PLAY==="+e.getMessage());
}
}
public void mediaPlayStop() {
try {
if (mp.isPlaying()) {
mp.stop();
}
} catch (Exception e) {
// TODO: handle exception
}
}
private static String getSoundPath(int countPositiong) {
// TODO Auto-generated method stub
String aa = "";
try {
if (countPositiong < 10) {
aa = "sounds/00" + countPositiong + ".mp4";
} else if (countPositiong < 100) {

You can use MediaPlayer.onCompletionListener to listen to the event when a track ends, so that you can play the next one
UPDATE
player.setDataSource(path);
player.prepare();
player.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer player) {
player.stop();
// play next audio file
}
});
player.start();
UPDATE 2
Your code in the comment won't work, this could be a solution:
int i = 0;
//somewhere in your activity you start playing your first file
playAudio("/sdcard/MyAudio/RecAudio"+i+".3gp");
public void playAudio(path) {
player.setDataSource(path);
player.prepare();
player.setOnCompletionListener(new OnCompletionListener() {
#Override public void onCompletion(MediaPlayer mp) {
player.stop();
if(i < numberOfFiles) {
i++;
playAudio("/sdcard/MyAudio/RecAudio"+i+".3gp");
} else i = 0;
}
});
player.start();
}

Yes this code will work fine but i have implemented differently and this will work more fine as given code
because if you play next file inside setOnCompletionListener method then it will call only single time i.e when playing first file it will call completion method and play another file but this time it will not call so you need to create new instance . dont worry just forget use
this
mc = new CountDownTimer(cownDownTime, 1000) {
public void onFinish() {
Log.i("call data hrer","aao bhai");
//initlize();
//updateText();
//startPlayProgressUpdater();
}
i.e play next file inside the Countdown timer finish() method it will run efficiently

Playing audio files one after another in android

I use the following code to record audio files and play. I have a resume function which starts recording again. The audio files are stored in sdcard. My problem is, the files get stored in the sdcard but the file alone play. I need to play all the recorded files one after another. Give suggestions. I am running out of time...
