BufferedInputStream, BufferedInputStream available

Good day, I have a problem with BufferedInputStream.
Code:
String url = "some path";
URL feedUrl = new URL(url);
inputStream = feedUrl.openStream();
BufferedInputStream buffer = new BufferedInputStream(inputStream);
Log.v("buffer.available", String.valueOf(buffer.available()));
why I always have a buffer size 2KB ?

It's the default buffer size. Use the constructor that you can specify buffer size if you want something bigger.

I think den_4ik asked about why there is always 2KB, even if there should be e.g. 20KB of data.
public synchronized int available() throws IOException
Returns an estimate of the number of bytes (...)

You can't know how much data is still there - it's stream, you know. If you really need data size, then you could load it into some memory buffer. Also for some streams you could "guess" its size, e.g.: you could check file size for FileInputStream or if you are fetching data through HTTP protocol, then you could read its length from HTTP headers, etc.

increase buffer size
i want to increase the buffer size/time for streaming live audio
is it an app specific setting, ie., on each radio streaming app?
or is it a media player setting?
i know how to mod an apk
i just need to know where in an app, or music.apk for instance, the value would be set for how long or how much a stream will be buffered
i want to increase it enormously, sick of dropping audio while in a moving car
my theory is that if the buffer was bigger/longer, i wouldnt notice the drop out as often
i have searched
i have not found the answer

[Q] Default media player

Hello everyone,
i'm trying to do a podcast software, but i can't find a way to play music througth the default media player.
What should i use?
I use now Mediaplayer() but it has no user interface (no pause, forward ...) which is pretty annoying.
Thank you for your answers!

Have you looked at the MediaController class:
http://developer.android.com/reference/android/widget/MediaController.html

By now, i used another method with Intent.
String path = "/sdcard/feed/"+ title+"/"+fileName + ".mp3";
Intent myIntent =new Intent(android.content.Intent.ACTION_VIEW);
myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
myIntent.setDataAndType(Uri.parse("file://"+ path),"audio/*");
startActivity(myIntent);
Which actually works for mp3s.
I am looking for the basic Android downloader (the one used by the market for example)
Do you know how to use it?
Thank you a lot

So you want to download the file first to the sdcard, then play it by launching the default program for MIME type "audio/*"? seems convoluted. The MediaPlayer object will do all this for you in streaming mode and the MediaController class will give you a nice interface.
Otherwise, I don't know what you mean by "basic Android downloader".

[Q] Hello, I have an issue with the media player on rotation

I have a media file playing in the oncreate, and everytime i switch over to landscape it replays the audio file, i cannot restrict it from turning to land scape because thats the purpose of the app, is there any way i can possible pause the player and start it up again once its on landscape?
i tried
if(alert.isPlaying() == true){
alert.stop;
}else{
alert.start;
}

I just typed this out in this post so i know i made an error, im still new to android programming.
Please and thank you,

Take a look at this.
You could also save if it has already been played in a variable.
Or make an extra class, maybe as activity to play to play the audio file. Use an addiotinaly variable to procted the class from being created twice, because we only want to play it once.
This should keep running in the background and not start again when going landscape mode because it is not part of the activity that is getting recreated when you switch your gui to landscape.

Thank you "Clicks Thanks button" Im going to be testing this out tomorrow morning.

how do i launch music player with a particular song / album?

i thought it may be with an intent but can't find anything, nor can i find anything in the mediaplayer class, but what do i have to do to trigger the stock music player and do i have to pass in a filename as the param?

mhh, something like:
Code:
Uri data = Uri.parse("file://" + mf1.getFilename());
MediaPlayer mp = android.media.MediaPlayer.create(this, data);
mp.start();
will only trigger it as a background process, not switch to it. and an intent view seems to launch a mini player inside the app, so how do i switch to the music player?

Note: TouchWiz has it's own DB for music for Samsung phones, so you know, we hate them (and the second method may/maynot work on TouchWiz phones).

thanks, i need to get my head around querying the content provider now!

[Q] audio recording issue...

Hi all i'm developing an app for audio recording.
So i used the MediaRecorder class to record. Unfortunately this class hasn't got the pause method so i can just start or stop.
How can i pause the recorder?
For example i'd like to do something like this:
press rec button to start recording
press pause button
press rec button to continue recording...
press stop to save and exit.
ps: I'd like to save the output file as amr or 3gp.
Any idea?

it doesnt appear to be possible with the api's provided by the MediaRecorder class. the way you would have to do it with a MediaRecorder is to record multiple files and then merge them into one audio file. i was thinking that you could append to the file using a file descriptor but then i realized that its not just a plain text file. its an audio file with headers and a complex compressed format and just appending another audio file on the end would do nothing. here are some links

this is a tough one.

this one isnt... =)
setOutputFormat(int outPutFormat);
where outPutFormat can be these values:
