play mp3 file in resource folder not working

I want to play an mp3 file in my res/raw folder.
But i get error as "error (1, -2147483648)" and IOException on mp.prepare()
My code
try {
MediaPlayer mPlayer = MediaPlayer.create(NavigationHome.this, R.raw.notfy);
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
I also tried with
try {
mp.setDataSource(NavigationHome.this, Uri.parse("android.resource://com.hipay_uae/res/raw/notfy"));
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
Another solution that I tried
AssetFileDescriptor afd = getAssets().openFd("AudioFile.mp3");
MediaPlayer player = new MediaPlayer();
player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
player.prepare();
player.start();
These too didn't work for me.

It will help more if you can post the StackTrace in your question.
But, as per the information in your question, the below code should work for playing the media file from the raw resource folder.
If you use the create() method, prepare() gets called internally and you don't need to explicitly call it.
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.notify);
mediaPlayer.start();
But, the point to consider is that prepare() generally throws an IllegalStateException, and in your case, you are getting an IOException. So it would be worth checking if the file is in fact present in raw folder and/or the file is corrupt.

Try to initialize your media player before preparing it or setting data source to it
Play From external directory
String filePath = Environment.getExternalStorageDirectory()+"/folderName/yourfile.mp3";
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();
mediaPlayer.start()
From raw folder
MediaPlayer mediaPlayer = MediaPlayer.create(MainActivity.this,R.raw.song);
mediaPlayer.start();

Try this
String fname="your_filename";
int resID=getResources().getIdentifier(fname, "raw", getPackageName());
MediaPlayer mediaPlayer=MediaPlayer.create(this,resID);
mediaPlayer.start();

playing android audio from a specified time

I have a prerecorded audio and i want to play it from a specific time to a specific time.
I have tried seekTo function in MediaPlayer but it doesnt seem to work.
mPlayer = new MediaPlayer();
try{
mPlayer.setDataSource(PATH_FILE + selectedAudio);

Android MediaPlayer won't play music from URL

I have a server side webapp which provides file upload and download functionality and an Android app which uploads music files onto the web site and then requests uploaded files by some URL.
My URL is structured like: http://mywebsite:8080/api/v1/files/fileById?fileId=<file_id>
When I'm trying to get a file from a web browser, it works fine; the browser downloads file and the OS can play it. But when I'm trying to put URL described before into MediaPlayer as a datasource, I'm getting java.io.IOException: setDataSource failed.
The code of MediaPlayer usage:
private void startPlaying(Uri fileUri) {
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(this, fileUri);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(preparedPlayer -> preparedPlayer.start());
}
catch (IOException e) {
LogUtil.loge(LOG_TAG, e);
stopPlaying();
return;
}
mediaPlayer.setOnCompletionListener(mp -> stopPlaying());
}
private void stopPlaying() {
if (mediaPlayer == null) { return; }
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
UPD: maybe I have to implement direct links to the files on a server side. all the samples for playing music from URL are requesting direct URL to the file.
Any suggestions?

If you want to play music from a URL, you have to input a String parameter.
Change to:
private void startPlaying(String url) {
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(url);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(preparedPlayer -> preparedPlayer.start());
}
catch (IOException e) {
LogUtil.loge(LOG_TAG, e);
stopPlaying();
return;
}
mediaPlayer.setOnCompletionListener(mp -> stopPlaying());
}

I think I can close this question because I've checked my code correctness by using URL for an external service which works fine. I found that this problem is a problem in my server side app. Android app code is correct.

background sound during call in android

I want to play a sound automatically when I call to somebody
but I don't know the way for this.
It is possible because we have some application that play some noise (traffic and ...) to background of call but I could not find a code or something for this
example of sound play in background
this is a code to play music
MediaPlayer player;
AssetFileDescriptor afd;
try {
// Read the music file from the asset folder
afd = getAssets().openFd(“home.mp3″);
// Creation of new media player;
player = new MediaPlayer();
// Set the player music source.
player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(),afd.getLength());
// Set the looping and play the music.
player.setLooping(true);
player.prepare();
player.start();
} catch (IOException e) {
e.printStackTrace();
}
but can we use this during call?
