I'm a Beginner in android programming and I want to programming mp3 app to call some mp3 files from URL, so when I show "Media Player" in android developer I put the URL in the setDataSource and it's work fine, but the problem is the Activity take a lot of time to display it and in the sometimes app will be crashed. This is the part of my code :
file_url = Mp3_Linkes[num];
//Set Source
try {
mp.setDataSource(file_url);
} catch (Exception e) {
Toast.makeText(this, "Source Error !!", Toast.LENGTH_LONG).show();
}
//Prepare
try {
mp.prepare();
}catch(Exception e)
{
Toast.makeText(this, "Prepare Error !!", Toast.LENGTH_LONG).show();
}
//Start
mp.start();
Your activity is blocking because you are calling prepare on your Main Thread (UI thread)
Instead You can use prepareAsynch and OnPreparedListener to start specially when loading from remote source:
code :
try {
mp.setDataSource(file_url);
mp.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer player) {
player.start();
}
});
mp.prepareAsync();

I am making a voice recording android app. The problem is that when I want to pause and continue the record it does not work and the app crashes. This is code :
buttonPause.setOnClickListener(new View.OnClickListener() {
#TargetApi(Build.VERSION_CODES.N)
#Override
public void onClick(View view) {
try {
recording=false;
mediaRecorder.pause();
recording=false;
buttonRecord.setBackgroundResource(R.drawable.record);
Toast.makeText(getActivity(), "Recording pause",
Toast.LENGTH_LONG).show();
}catch (Exception e){
}
and this appears on log
enter image description here
Please add the log of the Error, or it's impossible to help you.
The MediaRecorder can be paused ("pause()") and resumed ("resume()"). The only case when Pause() throws an Exception is when it is called before a "start()" or after a "stop()".
I'm totally new to Android Development and to Android devices in general, so I don't know how things are working here.
I want to make an app that will stream music from my url and still playing the song after I minimize the application.
I searched my question but a lot of answers were for mp3 songs or other types, but my url is from a live radio so it isn't one song only.
One of the answers that I found and were good for my problem was this and uses this code:
Uri myUri = Uri.parse("your url here");
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(myUri, "audio/*");
startActivity(intent);
This prompt me to choose a music player.
Is there any way to just press my "play" button and hear the music?
In my iOS app I use this code and I can start and stop the streaming music whenever I want without an external player:
func prepareToPlay() {
let url = URL(string: "myUrl")
playerItem = AVPlayerItem(url: url!)
player = AVPlayer(playerItem: playerItem)
player?.play()
}
Thanks in advance
EDIT
After suggested in comments and answer I tried to play it with MPlayer, I made a function and I called it when I tapped my button like this:
public void playM() {
String url = "http://android.programmerguru.com/wp-content/uploads/2013/04/hosannatelugu.mp3";
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
try {
mPlayer.prepare();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
}
mPlayer.start();
}
But I get an error (the fourth message) and I saw in the logs this:
Unable to create media player
prepareAsync called in state 1, mPlayer(0x0)
start called in state 1, mPlayer(0x0)
error (-38, 0)
Intent with ACTION flag is intended to open another app in most cases. Since you don't need it. You want your own custom player. So Android has a Media Player class for such scenarios.
Create instance of it and pass your stream-URL. Now, set the data-source and call prepare() after that in onBtnClickListener() start the music by calling mp.start()
Uri myUri = ....; // initialize Uri here
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(getApplicationContext(), myUri);
mediaPlayer.prepare();
mediaPlayer.start();
P.S: Catch all the exceptions and make sure the PERMISSIONS in manifest file
Intent is using only for sending some data between activities/services and system. It won't play the music. It don't do anything except saying to some activity what to do. You need the mechanism which will play your multimedia stream. You should use MediaPlayer class for playing multimedia inside your application.
Here's some tutorial, how to play music from stream: http://programmerguru.com/android-tutorial/android-mediaplayer-example-play-from-internet/
I am using the mediaplayer feature on Android. I basically have songs in the raw folder and I would just like to change to a new track but it fails. One music file plays and then I press a button after or during the music playing to skip to a random track but it fails.
Current code
mediaplayer.stop();
try {
mediaplayer.prepareAysn();
mediaPlayer.selectTrack(randomtrack_num - 1);
}
catch(Exception e){}
mediaplayer.start();
The error that I receive:
MediaPlayer: start called in state 64
MediaPlayer: error (-38, 0)
MediaPlayer: Error (-38,0)
I tried this without mediaplayer.stop() and still included mediaplayer.start() at the end and it would just replay the same track again.
Am I missing something?
Please let me know.
2nd Approach
After reading the document I realized this can only be done in the prepared state which I assume in my second approach it should work but it is not.
mediaPlayer.stop();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer mp) {
try{
mp.selectTrack(randomtrack_num - 1);
}catch(Exception e){}
mp.start();
}
});
mediaPlayer.prepareAsync();
I get this error:/MediaPlayer: Should have subtitle controller already set
Basically the same track plays again and it does not go to the selected track.
You are calling mediaplayer.start() in wrong state. Firstly read this documentation:
https://developer.android.com/reference/android/media/MediaPlayer.html
You will have a better idea of correct implementation.
EDITED:
String[] url ; // initiliaze your URL array here
MediaPlayer myMediaPlayer = new MediaPlayer();
myMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
myMediaPlayer.setDataSource(url[0]);
myMediaPlayer.prepareAsync(); // might take long! (for buffering, etc)
} catch (IOException e) {
Toast.makeText(this, "mp3 not found", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
//mp3 will be started after completion of preparing...
myMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer player) {
player.start();
}
});
Playing different track after completions
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp)
{
myMediaPlayer.reset();
/* load the new source */
myMediaPlayer.setDataSource(url[position]);//select the path according to your need
/* Prepare the mediaplayer */
myMediaPlayer.prepareAsync();
}
i am using the MediaPlayer class to loop music from youtube. So far no problem, but the MediaPlayer downloads the video every playback again from youtube, which causes a lot of traffic. Is there a way to let the video in the buffer of the MediaPlayer?
I'm using the following code:
try {
MediaPlayer mp = new MediaPlayer();
mp.setDataSource("http://r6---sn-4g57knsy.googlevideo.com/videoplayback?itag=18&key=yt5&ip=123.45.67.89&ipbits=0&ratebypass=yes&ms=au&source=youtube&sver=3&mt=1383664037&id=3fa390e8443132e0&expire=1383690428&sparams=gcr%2Cid%2Cip%2Cipbits%2Citag%2Cratebypass%2Csource%2Cupn%2Cexpire&fexp=935610%2C932206%2C916807%2C941242%2C916623%2C924616%2C907231%2C907240&mv=m&gcr=de&upn=9y98yq_WFEc&signature=98E548B5E368061D425FED483828E6D5AF1BBC2B.8AB359B7BA604F108D85578BC704844308E9B6EB");
mp.setLooping(true);
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
Thanks.
Short answer: no.
Long answer: write a simple proxy server to run on the device and cache it yourself. It's not incredibly hard, but it requires some thought to pull off seemlessly.
im making a music app just for fun. I can read all my music files from sd card but MediaPlayer wont play the sound. I have the path to the file which i pass to the media player with setDataSource but nothing happens and i get no exceptions. Here is the code im using.
Uri songUri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player);
setUpViews();
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(songUri.toString());
mp.prepare();
} catch (IllegalArgumentException e) {
Toast.makeText(this, "ILLEGAL ARGUMENT EXCEPTION", Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (SecurityException e) {
Toast.makeText(this, "SECURITY EXCEPTION", Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (IllegalStateException e) {
Toast.makeText(this, "ILLEGAL STATE EXCEPTION", Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (IOException e) {
Toast.makeText(this, "IO EXCEPTION", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
mp.start();
Log.d("URI AFTER SET UP", songUri.toString());
}
As i said before nothing happens when i open this activity but i still get all the Log.d in the console. Is there any more configurations for the media player to play the music? Thanks in advance.
setDataSource() requires a path argument . You are passing the entire uri as string. Try this :
mp.setDataSource(songUri.getPath());
mp.prepare();
mp.start();
Moreover, if you are trying to access a file with content:// uri, it won't work. You'll have to find the real path to the file, i.e file:// uri.
I think you have to add setAudioStreamType to your MediaPlayer Object. You can add this before mp.setDataSource(your_URI); like below
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
There other types, you can choose AudioManager.STREAM_MUSIC for Music Player
I just solved the problem, and i just dont know why it works. What i did was to put a button to stop the music being played. I dont understand why it works so if someone could explain why it does i'd be thanksfull.
get the path of song by querying MEDIASTORE-EXTERNAL_URI.And this field MEDIASTORE.AUDIO.MEDIA.DATA will give u the path of the song(which is string). U can set it directly to mediaplayer.setDataSource(Your_path_from_mediastore) .It will work fine than.
