Android : MediaPlayer With Stream Over Network
Feb 17, 2009
I would like to receive an audio stream from an application running on a PC using the 802.11 connection. I tried the following and received Error (-1, 0) from the MediaPlayer:
mp = new MediaPlayer(); mp.setAudioStreamType(AudioManager.STREAM_MUSIC); mp.setDataSource("http://10.1.201.114:11224");
The MediaPlayer does connect to the application and the application starts sending audio but nothing happens on the G1. Is the setDataSource call above correct? If so, how do I set things like sample rate, etc? If not, any help would be great!

I am trying to make a very simple radio player for Android and I cannot get the audio streaming to work. In my latest attempt it plays for about 1 second and stops for some streams and it doesnt work at all for some other streams. Logcat doesn't give much useful information to me. I am testing on HTC Hero (Android 1.5).
If I hook the completion and buffer events I see the audio gets a complete event but it keeps buffering. Is there anything wrong with the code below? Should I be able to stream the the audio streams below? Is there a complete example somewhere of a working radio streaming?................

I'm trying to create a way to adjust volume settings for each of the different streams (media, notification, ringtone, etc) and have a way to preview the output sound level of each stream. I believe I have the correct implementation, but when I set the output stream type, there is no sound that plays.
Here is the code that correctly plays the user's selected alarm sound:
CODE:.................
That commented out line is what is causing me problems. I would like to hear the alarm sound at the volume levels of the different audio streams, but when I include that line for STREAM_ALARM or any other audio stream, no sound at all plays.

I've been using androids MediaPlayer to stream from an http url and have a question about seeking. Currently, our urls expire after they have been used once or a certain time out has expired to dissuade scraping content. Now, this obviously makes progressive streaming past the buffer impossible with the exact same url as you need to open a new http connection with the same mangled key, which we intentionally don't allow.
However, MediaPlayer seems to do this when seeking before the current position (i.e. seeking from 1:00 in the audio to 0:30). As the file has already been downloaded up to the current position I'm confused as to why MediaPlayer is still trying to initate a new http connection in this case? The only thing I can think of is that MediaPlayer is getting rid of audio its already played up to the current position, and hence needs to restart the connection if you try to seek back on the stream. Is this correct, or is there something else going on?

I have an app that worked fine on Android 2.1 (Eclair) but is no longer working in 2.2.1 (Froyo). I think this may have to do with the shift from OpenCore to StageFright for video encoding and decoding, but am unsure.
The debug logs show two things I'm not sure about:
Does this mean H.264 baseline is not supported? WARN/QCvdec(59): Parsing Error unsupported profile or level No idea about: ERROR/PVOMXVidDecNode(59): Ln 1373 OMX_EventError nData1 -2147479542 nData2 0

First, sorry but my English is bad. I'm developing an app for android. I use a function (see below) for transfer a file on the network. removed some code...
Two situation: -S1: in is get from a socket and out is a locale file -S2: in is the local file and out is get from a socket
Well ! S1 and S2 work on the emulator. But, on a real device, S1 make some problem. The file is mixed :/ ! For example i would to transfer this text: "123456789ABCDEF 123456789ABCDEF 123456789ABCDEF 123456789ABCDEF 123456789ABCDEF 123456789ABCDEF 123456789ABCDEF" But i receive this: "123456789ABCDEF 12345678923456789ABCDEF 123456789ABCDEF 123456789ABCDEF 12345678ABCDEF 123456789ABCDEF 123456789ABCDEF 123456789" (not really a real example) The content received have same size as the source. Look at this: "123456789ABCDEF" is send and "12345678ABCDEF" is received.
How does it is possible ? Someone can help me?

Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

There is an online stream that is 512Kb MPEG4 and total size of 312mb online and if I'm correct after looking over docs in order to play the movie I just simply put:
CODE:..................
It is triggered to play after a button press which after a few seconds after pressing the button it plays the audio BUT doesn't show the video, why not? Do I have to use a surface view or something for visual playback of the stream.

I have a requirement to play several sounds many times in my game so instead of creating the MediaPlayer again and again I have called mp.seekTo(0) in onCompletion(mp) so that it will restart. Sometimes the sound is not audible from the device when I call mp.start () after setting mp.seekTo(0); but the player calls onCompletion() without playing any sound, this is observed randomly on most of the sounds
My sounds are of short duration mostly less than a second.
I am using a separate MediaPlayer for each sound (as I need this) -
There are almost 28 sounds in my game so i will be creating 28 MediaPlayers.
Below is the attached code for player
Also If I try to play many sounds one after the other in a short period of time i get an error saying "no more track names available". can u tell Why this is happening...?
check the below code:

I have connected my HTC Desire to a samba share where I have my music, movies, etc, but I cannot make Desire play any of the mp3, movies, and I cannot see any photos either? I am using Astro File Manager.
I get no kind of error messages just a black screen with a little icon (which I don't remember right now.) Anyone got an idea of what could be wrong?

I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

I'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally)

In 1.6 I do the following to stream an mp3 shoutcast stream:
CODE:...........
This works great. However, I have to support phones running 1.5 as well. When I build against the 1.5 libraries and run in a level 3 emulator, I get an exception on the prepare() call with the message: Prepare failed.: status=0x1.
Is this supported in 1.5. Is there some other mechanism I have to use that will work in both?

I have such code:..............
When my sound played for the first time, it's all fine. But when for second, third, etc.. it sounds like cutted, just little part of my "click.wav". If I put there sound in another format like mp3 or ogg - all just fine.
Or if I write like this: mp_click = MediaPlayer.create(CubeTest_Main.Context, R.raw.click); mp_click.start(); All if fine too, but this is a bit slow, becouse this sound is playing very often.

do you know how to get the Home country code, current country code, the Mobile directory number on a cdma network. I see TelephonyManager.getNetworkCountryIso() can get the current country code, but it is not reliable on cdma network.

I am developing a media player application which downloads from internet and plays. so while downloading I want to show a progress bar saying "buffering...", and while playing I want to dismiss the same progress bar. I can display the progress bar while downloading (by implementing the listener onBufferedUpdateListener), how can I get the event for player while it is playing.

I am developing a media player which will download the media content from network (Shoutcast) It works fine. Problem is a small gap between players (2 players) I am using two mediaplayers to play the data while a thread downloads and stores the data and stores in to 100Kb files continuously. on first players oncompletelistener() i started the second player wise versa. I think there is a problem with mp3 frames(header sync byte) while splitting 100kb files. how to resole the gap between players.

I know this question has been asked previously because I have read the other postings over a hundred times but yet I cannot come up with an answer on how to use keep a MediaPlayer object playing over an orientation change. I've read that you can use onRetainNonConfigurationInstance() to pass an object to your future self when the activity is destroyed/recreated, but I can't keep a video playing in this circumstances. Does anybody have an example or an advice/guide on how to do this? or rather what do I pass on onRetainNonConfigurationInstance() to keep the video playing after an orientation change?

What is the best way to use the MediaPlayer when needed multiple times?
Reuse the instantiated MediaPlayer throughout the session? Or constantly stop() release() and instantiate a new MediaPlayer() ?
If I reuse I'm afraid the player could be in a bad state? What about performance wise? what's better? reuse or renew?
This is for using as a music player so one audio be present at one given time...

I want to play a video file sitting in a server by setting local sdp file in the mediaplayer.
How to set the mediaplayer to read the local sdp file and start playing depending on the sdp connect (if it has unicast/multicast, start corresponding session)? I want to test unicast for now.
