How can i replay a .mp3 in my app? I can't replay the mp3 using the start method
Here is the code segment :
mMediaPlayer = MediaPlayer.create(MainActivity.this, R.raw.splashsound);
mMediaPlayer.setLooping(true);
Button myButtonOne = (Button) findViewById(R.id.songon);
myButtonOne.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mMediaPlayer.start();
}
});
Button myButtonTwo = (Button) findViewById(R.id.songoff);
myButtonTwo.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(mMediaPlayer.isPlaying()){
//mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
}
});
Can anyone please tell me what i am doing wrong here?
If you want to replay the mp3 why do release and set to null your media player?
I guess that is your problem!
Just stop and start it again without releasing your media player instance.
To replay mp3 track try this:
private void playSong(int songIndex) {
// Play song
try {
mp.reset();
mp.setDataSource(songsList.get(songIndex).get("songPath"));
mp.prepare();
mp.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Or without calling reset():
mediaPlayer.setLooping(true);
I am making an app that uses sound effects. I would like to know how i can detect when a sound has finished playing and trigger an event .
i tried this :
player = new MediaPlayer();
if (player != null) {
player.reset();
player.release();
}
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
sonar.setBackgroundResource(R.drawable.sonar_off);
stopPlay();
}
});
if(state==1){
player = MediaPlayer.create(this, R.raw.sonar_slow);
}else if(state==2){
player = MediaPlayer.create(this, R.raw.sonar_medium);
}else if(state==3){
player = MediaPlayer.create(this, R.raw.sonar_fast);
}
try{
player.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
player.start();
You can set an OnCompleteListener() to the player object. The code for it is:
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp)
{
"your code comes here"
}
});
Here the mPlayer is the object of the MediaPlayer which is currently running.
There are multiple ways to play sounds, assuming you use the MediaPlayer class you could register a MediaPlayer.OnCompletionListener
So I have mediaplayer which plays audio files from the phone. To play them i use this code for the Play button
try {
if (mp2.isPlaying()) {
mp2.reset();
}
mp2.setDataSource(s1); //using path here
mp2.prepare();
mp2.start();
mp2.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method
mp.reset();
}
});
} catch (Exception e) {
}
I want to pause the song and continue to play it with the same code, I tried mp2.pause();
but if i click on play button nothing will happen. I dont wanna to remove if (mp2.isPlaying()) {
mp2.reset();
}
I am currently trying to design a simple app that streams an internet radio station. I have the URL for the station and am setting up the Media Player like
MediaPlayer mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(URL);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mediaPlayer.start();
The program isn't crashing when emulated, but nothing is playing and I am get the following error:
start called in state 0
and right below it is
Error (-38,0)
Does anyone know what this means?
I've read a little about these state errors, but couldn't find anything that applies to my project.
You need to call mediaPlayer.start() in the onPrepared method by using a listener.
You are getting this error because you are calling mediaPlayer.start() before it has reached the prepared state.
Here is how you can do it :
mp.setDataSource(url);
mp.setOnPreparedListener(this);
mp.prepareAsync();
public void onPrepared(MediaPlayer player) {
player.start();
}
It seems like Error -38 means a state-exception (as the error-message indicates). For example if you call start(), before the song was ready, or when you call pause(), even if the song isn't playing at all.
To fix this issue check the state of the mediaPlayer before calling the methods. For example:
if(mediaPlayer.isPlaying()) {
mediaPlayer.pause();
}
Additionally, the MediaPlayer is sending event-messages. Even if you do not need the prepared-event (although it would be a good idea to not start the playback before this event was fired) you must set a callback-listener. This also holds true for the OnErrorListener, OnCompletionListener, OnPreparedListener and OnSeekCompletedListener (if you call the seek method).
Listeners can be attached simply by
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
// Do something. For example: playButton.setEnabled(true);
}
});
I got this error when I was trying to get the current position (MediaPlayer.getCurrentPosition()) of media player when it wasn't in the prepared stated. I got around this by Keeping track of its state and only calling the getCurrentPosition() method after onPreparedListener is called.
This is my code,tested and working fine:
package com.example.com.mak.mediaplayer;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.app.Activity;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final MediaPlayer mpp = MediaPlayer.create(this, R.raw.red); //mp3 file in res/raw folder
Button btnplay = (Button) findViewById(R.id.btnplay); //Play
btnplay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View vone) {
mpp.start();
}
});
Button btnpause = (Button) findViewById(R.id.btnpause); //Pause
btnpause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View vtwo) {
if (mpp.isPlaying()) {
mpp.pause();
mpp.seekTo(0);
}
}
});
}
}
I encountered the same issue few days ago. My audio MediaPlayer works fine on devices with high processing power, but for slow devices, the media player just did not play some time and from LogCat it had many complain about called in wrong state. So I resolved it by calling putting the call to start(), pause(),... in onPrepared() method of OnPreparedListener() as below:
mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
........
mediaPlayer.start();
....
songControlBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
} else {
mediaPlayer.start();
}
}
});
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
............
}
});
}
});
Also try to release any media player that you do not need any more. For example, if you do not want to play the audio or video on background then you should call mediaPlayer.release() in onPause().
i tested below code. working fine
public class test extends Activity implements OnErrorListener, OnPreparedListener {
private MediaPlayer player;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
player.setDataSource("http://www.hubharp.com/web_sound/BachGavotte.mp3");
player.setOnErrorListener(this);
player.setOnPreparedListener(this);
player.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void onDestroy() {
super.onDestroy();
player.release();
player = null;
}
#Override
public void onPrepared(MediaPlayer play) {
play.start();
}
#Override
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
return false;
}
}
Some times file are encoded in a way that Android can't decode. Even some mp4 files can not be played. Please try a different file format (.3gp are played most of the time) and see..
You get this message in the logs, because you do something that is not allowed in the current state of your MediaPlayer instance.
Therefore you should always register an error handler to catch those things (as #tidbeck suggested).
At first, I advice you to take a look at the documentation for the MediaPlayer class and get an understanding of what that with states means. See: http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram
Your mistake here could well be one of the common ones, the others wrote here, but in general, I would take a look at the documentation of what methods are valid to call in what state: http://developer.android.com/reference/android/media/MediaPlayer.html#Valid_and_Invalid_States
In my example it was the method mediaPlayer.CurrentPosition, that I called while the media player was in a state, where it was not allowed to call this property.
above the picture,you can get the right way.
I solved both the errors (-19,0) and (-38,0) , by creating a new object of MediaPlayer every time before playing and releasing it after that.
Before :
void play(int resourceID) {
if (getActivity() != null) {
//Using the same object - Problem persists
player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
After:
void play(int resourceID) {
if (getActivity() != null) {
//Problem Solved
//Creating new MediaPlayer object every time and releasing it after completion
final MediaPlayer player = MediaPlayer.create(getActivity(), resourceID);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.release();
}
});
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
}
if(length>0)
{
mediaPlayer = new MediaPlayer();
Log.d("length",""+length);
try {
mediaPlayer.setDataSource(getApplication(),Uri.parse(uri));
} catch(IOException e) {
e.printStackTrace();
}
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.seekTo(length);
mediaPlayer.start();
}
});
mediaPlayer.prepareAsync();
It was every much frustrated. So, I got solution which works for me.
try {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(file.getAbsolutePath());
mediaPlayer.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer = null;
}
});
}
});
mediaPlayer.prepare();
} catch (Exception e) {
e.printStackTrace();
}
For me this worked
mp.seekTo(0);
mp.start();
I also got this error i tried with onPreparedListener but still got this error. Finally i got the solution that error is my fault because i forgot the internet permission in Android Manifest xml. :)
<uses-permission android:name="android.permission.INTERNET" />
I used sample coding for mediaplayer. I used in StreamService.java
onCreate method
String url = "http://s17.myradiostream.com:11474/";
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(url);
mediaPlayer.prepare();
mp = new MediaPlayer();
AssetFileDescriptor afd = mContext.getAssets().openFd(fileName);
mp.reset();
mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
mp.prepare();
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.prepareAsync();
I have change setAudioStreamType to setAudioAttributes;
mediaPlayer.setAudioAttributes(AudioAttributes.Builder()
.setFlags(AudioAttributes.FLAG_AUDIBILITY_ENFORCED)
.setLegacyStreamType(AudioManager.STREAM_ALARM)
.setUsage(AudioAttributes.USAGE_ALARM)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build());
I am new in android programming and i had same error as this one. so i simply redefined the mp.createmediaPlayer = MediaPlayer.create(getApplicationContext(), Settings.System.DEFAULT_RINGTONE_URI). It may not the true way to do it but it worked fined for me:
try {
mp = MediaPlayer.create(getApplicationContext(), Settings.System.DEFAULT_RINGTONE_URI);
} catch (Exception e) {
e.printStackTrace();
}
mp.start();
I'm a noob trying to work something out and learn from it.
I have two imagebuttons and when i click them I get a kind of "schick" sound rather than the sound files that i have in the /res/raw/ directory.
This is my code:
public void button_clicked1(View v)
{
text1.setText("1"+width);
mp = MediaPlayer.create(GameScreen.this, R.raw.a);
mp.start();
}
public void button_clicked2(View v)
{
text1.setText("2"+height);
mp = MediaPlayer.create(GameScreen.this, R.raw.b);
mp.start();
}
What am I doing wrong?
Thanks!
Ok, changed the above code to this:
public void button_clicked1(View v)
{
text1.setText("1"+width);
mp = MediaPlayer.create(GameScreen.this, R.raw.piano_a);
try {
mp .prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
}
public void button_clicked2(View v)
{
text1.setText("2"+height);
mp = MediaPlayer.create(GameScreen.this, R.raw.piano_b);
try {
mp .prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
}
And it still does not work
EDIT: Try this:
setVolumeControlStream(AudioManager.STREAM_MUSIC);
in your main application code. This will tell the AudioManager that when your application has focus, the volume keys should adjust music volume (found that here).
After that, make sure that your volume is up - it may just be playing the sounds with no volume.
