I am trying to play an audio file from the internal storage.
The code I used is..
package com.abhi.firstapp.firstapp;
import android.content.Context;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;

import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
import java.io.File;
import java.io.IOException;
import java.net.URI;
public class MainActivity extends AppCompatActivity {
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
File f= new File("/sdcard/a.mp3");
if(f.exists())
{
Toast toast= Toast.makeText(this, "file exists", Toast.LENGTH_LONG);
toast.show();
Log.d("uri","1");
Uri uri= Uri.fromFile(f);
Log.d("uri", "2");
mp= new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
Log.d("uri", "3");
try {
mp.setDataSource("/sdcard/a.mp3");
} catch (IOException e) {
e.printStackTrace();
}
//mp.setDataSource(getBaseContext(), uri);
Log.d("uri", "4");
try {
mp.prepare();
} catch (IOException e) {
e.printStackTrace();
Log.d("uri", "IOException");
}
mp.start();
}
else {
Toast toast1 = Toast.makeText(this, "file does not exist", Toast.LENGTH_LONG);
toast1.show();
}
//MediaPlayer mp= MediaPlayer.create(getBaseContext(), uri);
//mp.start();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
By using the log, I can determine that this code is running till the mp.prepare(mediaplayer prepare). And on this step, it gives the error Illegal State Exception
Caused by: java.lang.IllegalStateException
at android.media.MediaPlayer.prepare(Native Method)
Please Help!
There are a couple of things you might want to change.
First: mp.prepare() will block your main thread, which is forbidden and will result in an exception where Android will close your app. To prevent this, mp.prepareAsync was designed. Use that method instead and implement both an onPreparedListener and an onErrorListener.
Second: you should provide a datasource before you call prepare().
You could do this for example this way:
public class MainActivity extends AppCompatActivity implements MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
MediaPlayer mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(streamURL);
} catch (IOException e) {
// Error, do something
}
mp.prepareAsync();
...
}
#Override
public void onPrepared(MediaPlayer player) {
mediaPlayer.start();
}
...
}
I had the same problem. It can be raised because MediaPlayer is already prepared. When you create a new MediaPlayer by MediaPlayer mp = MediaPlayer.create(getContext(),someUri); mp prepares automatically so you should not prepare it by yourself.

I'm following an Udemy class on making a MP3 player like Spotify. I'm new to Android studio, and know/understand very little. The class is a bit older, and uses an older version of Android Studio from 2 years ago, so this might be part of the problem. I can hear the MP3 when I first start debugging, and the button will also change from play to pause, however, it is unresponsive to any clicking. I hear the sound it's been clicked, but it never changes status or pauses the audio. Thank you for the assistance, it's greatly appreciated!

I believe this is exactly what happens after you click the button, namely - nothing. You should put something inside that function. You override the onClick function and leave it empty, so anything you would want to happen after clicking, you should put inside it.
Your "togglePlayer()" is never used, perhaps that's what you should put in the listener.
I just have only basic knowledge about android. today i developed one audio recording application, but the problem is user can record audio and it can play the audio, when it runs the second time(or user press the record button again) the newly recorded file replaces withe the old file from the storage, i want create new file for each and every recording operations , how to do that ?
this is my main activity

On your record button click use this line
outputfile= Environment.getExternalStorageDirectory().getAbsolutePath()+"/recording_"+System.currentTimeMillis()+".mp3";
If you give same file name, the file will be override the old one.
Use Calendar.getInstance().getTimeInMillis() to create unique files name for each recording.
outputfile=Environment.getExternalStorageDirectory().getAbsolutePath()+"/recording_"+ Calendar.getInstance().getTimeInMillis()+".mp3";
Also create one function to create new audio file and initialise recorder with new file reference.
private void prepareNewRecording() {
outputfile=Environment.getExternalStorageDirectory().getAbsolutePath()+"/recording_"+ Calendar.getInstance().getTimeInMillis()+".mp3";
myAudioRecorder=newMediaRecorder();
myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
myAudioRecorder.setOutputFile(outputfile);
}
Now call above function from start recording
prepareNewRecording();
myAudioRecorder.prepare();
myAudioRecorder.start();
I am playing an audio (.mp3) from the server url using the following Android code. But, it is not playing the audio, simply does nothing, no errors. I have set Android min 11 to 22. I am testing on 5.0.2 Android phone. Could someone help what could be the reason not playing, please?
UPDATED:
I have solved it now. I converted google drive url to google drive download url using the help this link, and able to play the audio well.

Look at these two tutorials, In these the .mp3 files are playing through web url,
Example of streaming mp3 mediafile from URL with Android MediaPlayer class
Play Mp3 file from a Url
Also if you want to play .mp3 file in background I think you have to use Service and AIDL for it,
Look at basic Android-Music Player demo MusicDroid - Audio Player Part II it describe how to use Service and AIDl for your Audio Player.

I have retrieved the songs present on my phone and when I click on the list item it switches to the next activity and plays the song.

I'm stuck with this problem since two days. Please help.
My advice: use a Service to host the MediaPlayer and have your Activities communicate with the Service to play and stop songs. Don't forget to call release on the MediaPlayer when you are done (if you use a new player for the next song).
Edit:
The Activity is not going to be the same instance each time it opens, and you create a new MediaPlayer each time an instance of the Activity is created. Underneath the hood, there is a native object actually playing the music that is not intrinsically tied to the life cycle of the Activity, and you aren't calling stop or pause anywhere that would get called when Activities are changed. You could potentially stop and release the MediaPlayer in an appropriate callback (onPause or onDestroy), but that will prevent you from playing music continuously. If you insist on using an Activity to host the MediaPlayer, then music playback has to be completely integrated into the life cycle of the Activity. When the Activity is changed, you need to stop and release its resources explicitly. If you put it in a Service, you won't have that limitation. You can manage one or more MediaPlayers (note the setNextMediaPlayer method) without them being tied to any particular Activity.
it will keep playing. You need to free your media player object when you press back button. In onPause(), release your media player object otherwise it will keep playing.
To implement music player, you can refer open source code. Refer VLC player source code.
before start playing song every time mMediaPlayer.reset() from that you can play new song every time or check if mediaplayer is playing or not if playing stop it
I'm new to android and I need it for a project I'm working on. I need it to play a sound by clicking a button. I followed online tutorials but my code does not play sounds at all and I'm getting an error on MediaPlayer Error(-19,0). I've tried a lot of the fixes I saw here and I can't seem to make it work. Any help? Here's the code

AudioManager audioManager = (AudioManager) getSystemService(MainActivity.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);
Button buttonHello = (Button) findViewById(R.id.button1);
buttonHello.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MediaPlayer mp = Medi aPlayer.create(MainActivity.this, R.raw.button);
mp.start();
mp.setOnCompletionListener(new OnCompletion Listener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
};
});
}
});
} catch (Exception e) {
System.out.println("Error!");
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
This links http://marakana.com/forums/android/examples/59.html has the great example to use MediaPlayer class to play song from raw folder.
To play song from files in the memory you can use the following code.
MediaPlayer mp = new MediaPlayer();
mp.reset();
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, filename.getAbsolutePath());
Uri selectedImage=RingtoneDownload.this.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
try {
mp.setDataSource(RingtoneDownload.this,selectedImage);
mp.prepare();
mp.start();
}catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
This code is working for me while set the source from file.
