Mediaplayer is slow, how to overcome this?

Problem:
I've created a single-radio app with MediaPlayer but prepare() method takes too much time (12-15 Seconds) and as a result when user hits the play button he/she waits for so long.
Is there anything I can do about it(I need to make it faster)? I found Exoplayer but little documentation/tutorials were found about it ;/
To be more specific here is what code I've written (Strings[0] is the URL)
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(strings[0]);
mediaPlayer.prepare();
I am open to any new suggestion or ideas

Android: Sound File Not Found

I know there are lots of similar problems to mine, but for some reason the answers to those questions don't seem to work. I am using android and have a sound file named 'backgroundbeat.wav' and I'm trying to import it but instead I get the error:
"failed to open file 'res\raw\backgroundbeat.wav'. (No such file in directory)"
Here is the code where I use the media player:
mp = new MediaPlayer();
try{
mp.setDataSource("res/raw/backgroundbeat.wav");
mp.prepare();
mp.start();
}catch(Exception e){
e.printStackTrace();
}

Use your app package name to define the correct path :
mp.setDataSource("android.resource://<YOURPACKAGE_NAME>/raw/backgroundbeat");
example:
mp.setDataSource("android.resource://com.jorgesys.myapp/raw/backgroundbeat");
or other way to load a media file from /raw folder, if you are inside an activity you could use:
mp = MediaPlayer.create(this, R.raw.backgroundbeat);
or You can use a VideoView to play your file
Videoview on splash screen

Not much experienced in this but you can try to use mediaPlayer.setDataSource(FileDescriptor fd) instead of mediaPlayer.setDataSource(String path). See MediaPlayer setDataSource, better to use path or FileDescriptor? . Apparently if you call prepare() while using string as a parameter to setDataSource, it is causing some issues as per the answers.
You may try something like:
// Use the proper context instead of *context* variable
InputStream in = context.getResources().openRawResource(R.raw.backgroundbeat);
mediaPlayer.setDataSource(in.getFD())
Let me know if it helps.

I cannot change a video using MediaPlayer without reseting

I am working with streaming video and I want to change from one source to another dinamically.
First I set the video uri to the VideoView
view.setVideoURI(myUri);
And I know that I am capable of changing it afterwards by doing (this is in onPrepare method but it could go somewhere else where I have access to the MediaPlayer).
#Override
public void onPrepared(MediaPlayer mp)
{
Uri newUri = getOtherUri();
mp.reset();
mp.setDataSource(getApplicationContext(), newUri);
mp.prepare();
mp.start();
}
The thing is, I want to change the source without reseting the mediaPlayer (I do not want to disturb the user).
I tried to create a new VideoView with the new Uri and then change one object for the other, and likewise with the media player. However, none of that seems to work.
Is it possible to replace a video while it is playing in Android?
Any comments would be appreciated.

There is no option to reset the video without using mediaplayer.stopPlayback() or mediaplayer.reset. The reason is that; the previous object of the mediaplayer has to be released before you can play other video .
I want to change the source without reseting the mediaPlayer (I do not want to disturb the user).
Well, this cannot be achieved as the mediaplayer has to be reset. So there will be lag while changing videos. And to satisfy you, you can see these behavior in any videoplayer app like youtube or mxplayer.
So the only thing you can do is to show progressbar while loading or changing video.
Hope it helps. Cheeers.:)

how can i play mp3 in andengine?

i want to play sound when my condition is matched, but i don't how can i play sound or music in andengine?
help me to find my solution.
your answer will be awarded.

You can obviously use the MediaPlayer in AndEngine too, it works fine as it does in Android, because AndEngine is also a part of Android itself.
You can keep your file in res/raw/anyfile.mp3
MediaPlayer mediaPlayer = MediaPlayer
.create(getApplicationContext(), R.raw.anyfile);
try {
mediaPlayer.start();
mediaPlayer.setLooping(true);
} catch (Exception e) {
e.printStackTrace();
}

though i haven't perform a sound task, but hope this tutorial link will help u,,

How to play online radio in android

I am working on android application in which i have play online radio streaming.
i have gone through the media player classes but i don't think is there any method to online streaming of radio. If any know about this please help me.
Thank You.
Vikram

Vikram,
You should be able to achieve this using the MediaPlayer; however, depending on your format it may be difficult. For example, if you're trying to play an online radio stream that uses .pls, or .m3u, you would have to parse that file, and pull out the true URLs to use.
Beyond that, you should be able to use MediaPlayer's create method with a URL to start streaming playback. Keep in mind that if the streams URL redirects (which it likely does) you may have to resolve the URL. A simple way to do this is use HttpURLConnection to open a connection, then connect(), then getURL(). You'll likely need a string url, so call toExternalForm() on the result from getURL().
Additionally, If things aren't working for you with MediaPlayer via URL, you might have to come up with your own buffering mechanism to get the data from the server. That being the case, you can try this tutorial: http://blog.pocketjourney.com/2008/04/04/tutorial-custom-media-streaming-for-androids-mediaplayer/

From what I've read, you should just be able to do:
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(streamingURL);
mediaPlayer.prepare();
mediaPlayer.start();
to get basic functionality I believe, but I haven't tested it myself.

the easiest way to play a radio channel in android is to use the built in MediaPlayer, however when the datasource is from web the prepare() method takes a long time to execute and you should use prepareAsync() instead to avoid blocking the ui:
player = new MediaPlayer();
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
player.start();
}
}
});
try {
player.setDataSource(currentChannelUrl);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (IOException e) {
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
e.printStackTrace();
return;
}
player.prepareAsync();
