I create a simple project with one layout that contains two buttons, and this is my code:
package com.example.tessound;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity implements OnClickListener
{
MediaPlayer player;
Button play,mute;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play = (Button)findViewById(R.id.button1);
play.setOnClickListener(this);
mute = (Button)findViewById(R.id.button2);
mute.setOnClickListener(this);
}
#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;
}
public void onClick(View view)
{
if(view.getId()==R.id.button1)
{
playSound(1);
}
else if(view.getId()==R.id.button2)
{
playSound(2);
}
}
public void playSound(int arg)
{
if (arg == 1)
{
player = MediaPlayer.create(this, R.raw.atur);
}
else if (arg == 2)
{
player = MediaPlayer.create(this, R.raw.back);
}
if(player != null)
{
player.setLooping(false);
player.start();
}
try
{
if(player != null)
{
if (player.isPlaying())
{
player.stop();
player.release();
}
}
}
catch(Exception e)
{
}
}
}
When I tried to click the button the sound doesn't play.
Following the logic for your playSound method with an argument value of 1:
1) arg == 1 so:
player = MediaPlayer.create(this, R.raw.atur);
2) player has been set so is not null, hence:
player.setLooping(false);
player.start();
3) Then it's your try block. player is not null and is playing, hence:
player.stop();
player.release();
So I think you are starting the playback and then immediately stopping it. I imagine you should only execute the try/catch code if the method does not receive a valid argument, i.e. it should be an 'else' of the preceding 'if' statement.
EDIT:
Looking at this again, I think the try/catch code should go at the top of the method. It will then stop the player and release it (if it is in use) before trying to start playing a new sound. Logically that makes sense.
Use Log to trace the control and find the error !
Log.e("AnyTAG","Description of the Log");
your code seems fine!

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 wanna make "Play/Stop" button. When button "Play" is clicked, the song must be played and its text should be converted into "Stop" and when "Stop" is clicked, the button text should be changed into "Play" again and song should start again to play from the beginning.
import android.media.MediaPlayer;

import android.os.Bundle;

#Override

setContentView(R.layout.activity_main);
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("Play Music");
mediaPlayer = MediaPlayer.create(MainActivity.this, R.raw.zara_sa);
btn_playStop = (Button)findViewById(R.id.btn_play_stop);
btn_playStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying() && flag==true){
stopSong();
}
else if (flag == false){
playSong();
}
}
});
}
public void playSong(){
mediaPlayer.start();
btn_playStop.setText("Stop");
flag = true;
}
public void stopSong() {
mediaPlayer.stop();
btn_playStop.setText("Play");
flag = false;
}
}
You must call mediaPlayer.prepare(); if you called mediaPlayer.stop(); so in the first time you can just call mediaPlayer.start(); but in the next times you should call mediaPlayer.prepare(); before mediaPlayer.start();
public void playSong(){
try {
mediaPlayer.prepare();
} catch (IOException e) {
}
mediaPlayer.start();
btn_playStop.setText("Stop");
flag = true;
}
I have songs from json in list view, and a play button in each row , after clicking on play Button my app freezes and App not responding dialog box comes, Sometime media player started after freezing sometimes its crashes. Because of App not responsive. This is my Code :
viewHolder.playButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
selectedPosition = position;
if (selectedPosition != mPlayingPosition) {
try {
mPlayerforplanet.reset();
mPlayerforplanet.setAudioStreamType(AudioManager.STREAM_MUSIC);
mPlayerforplanet.setDataSource(song_urls);
logger.addRecordToLog("MediaPlayer audio session ID: " + mPlayerforplanet.getAudioSessionId());
logger.addRecordToLog("Media Player started " + "Started !");
mPlayerforplanet.prepare();
mPlayerforplanet.start();
} catch (IOException e) {
e.printStackTrace();
}
// playSongs(position);(i also try with method of playsong but no luck)
Toast.makeText(getContext(), "play song" + mPlayingPosition, Toast.LENGTH_SHORT).show();
}}});
Log cat after click on play button

Please use prepareAsync instead of prepare and handle onPrepared and trigger start from there .
mPlayerforplanet.prepareAsync();
public void onPrepared(MediaPlayer mp) {
mPlayerforplanet.start;
}

For seek-bar use a anew runnable :
Starting runnable ,
public void onPrepared(MediaPlayer player) {
mPlayerforplanet.start();
mUpdateSeekBar.run();
}
Code in runnable
private final Runnable mUpdateSeekBar = new Runnable() {
#Override
public void run() {
int elapsedtime = mPlayerforplanet.getCurrentPosition();
/* update UI with getCurrentPosition*/
mHandler.postDelayed(mUpdateSeekBar, 1000);
}
};
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:

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.
Thanks..

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
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
MediaPlayer player;
#Override
protected void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
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.
