I hope someone can help me with this.
Here's y problem: I have an icecast server with a couple of channels. I developed an app to listen those stations but when I change from one station to another one the app gets really slow.
Here's the code to change the station:
public static void setAndPlay(MediaPlayer player, String source) {
player.reset();
try {
player.setDataSource(source);
player.prepare();
} catch (IOException e) {
//TODO: handle exception
}
}
And here's when the mediaPlayer starts:
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer player) {
player.start();
}
});

I have an android app with a detail activity, that detail activity has few tabs with underlying fragments. One of these fragments is plain list with a name of audio files when I click each line I'm playing the clicked audio files.
Everything works OK, but I would like to have some means of seeing a progress of the playback and ability to stop a playback, I was trying to add MediaController but even though I'm creating it without errors no media control is visible on a screen.
I'm not sure if I'm doing it in a correct way any help you would be appreciated.
Thanks a lot,
Radek

Please check the below code for your refrence
In your code you have passed the TextView in the mediaController need to pass the SurfaceView instead of TextView and you need to set the MediaPlayer in the MediaController

I have a problem. This is stream player it is playing fine but when I start play, change app and again start player app the stop button is disabled.
If I pressing play again - it start plaing double music and I cannot stop first stream playing.
In short: I need one app and one sound and possibility to stop sound (without double playing)

When the screen is locked your onPause is being called, and you are explicitly stopping the player there.
I'm making two apps - receiver and sender, each of which goes on an Android device. The sender should be able to stream local audio files to the receiver, over Wifi, preferably using UDP or RTP.
I have made the receiver app, it runs fine on Internet radio stations and all, but the trouble now is in making the sender app. I haven't been able to find any reliable resources online.
Some of the resources I referred to and why they haven't helped:
#1
Audiotrack doesn't support mp3, which would be a major disadvantage.
#2
This uses something called a ParcelFileDescriptor. Whether this is the result of reading too many unfamiliar API's or not, I just cannot understand what that line ParcelFileDescriptor socketedFile = ParcelFileDescriptor.fromSocket(socket) is doing. It seems to be creating a new parcelfiledescriptor from socket, but I thought the code was supposed to be sending it to socket.
So can anyone suggest either an alternative, or a modification of the above types of code that would work for my application? For your reference, I'm attaching the source code of the receiver side app.

i use these lines to play some audio file with mediaplayer, both on a service and in an activity, yet there is no sound on my device, what could be the reason? and what should i try to do to understand whats wrong and finally fix that?

Check out the state diagram in the MediaPlayer docs.
After you've created the MediaPlayer it is in the Idle state. As you can see, you need to initialize and prepare it before you call start().
Check the following code, it works fine for me. I hope it will work for you also.....Dont forget to add Audio PlayBack permission in android Manifest File
