Android :: How To Implement An Audio Player - Using MediaPlayer And MediaController
Feb 8, 2010
I want to create an Android application that is a client for an Internet radio station. And I want it look native to Android? But im confused with Android API logic and documentation. What i've got is that I need MediaPlayer and MediaController classes. Am I right, and is there any good example of AUDIO player for Android?
Especially, I'm very interested how to use MediaPlayer and MediaController classes together.
UPD:
Finally I've got the code, that does exactly what I want:

The seek bar of Mediacontroller is not been updating according to de audio player. Only when the trackball is shifted, or the play/pause button is clicked, the seek bar tracks the audio player. Could anybody give me any clue?

I am using MediaPlayer to build a Video player for playing local video files. However, I don't know how to enable MediaController for my player. I want the media control buttons that pop up when you touch the video surface.

I've been trying to stream mp3's over http using Android's built in MediaPlayer class. The documentation would suggest to me that this should be as easy as :
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(URL_OF_FILE);
mp.prepare();
mp.start();
However I am getting the following repeatedly. I have tried different URLs as well. Please don't tell me that streaming doesn't work on mp3's.
E/PlayerDriver( 31): Command PLAYER_SET_DATA_SOURCE completed with an error or info PVMFErrNotSupported
W/PlayerDriver( 31): PVMFInfoErrorHandlingComplete

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.

Some audio files return 0 from MediaPlayer.getDuration(), even though they're perfectly valid files that play ok and that players on Windows can find the duration of. There seem to be two different cases here: certain file types such as .wma and .wav always return 0 duration, and others only do so sometimes. I haven't been able to find any pattern in the latter case, but it does seem consistent per file. The music player displays 0:00 duration for these, so it's not just my code.

I am having the following problem: I am using Android's MediaPlayer to play an mp3 through an HTTP connection. The audio is played correctly, but the MediaPlayer returns an incorrect duration (calling mediaPlayer.getDuration() ). Depending on the mp3 the duration is either shorter or longer. The code that plays the audio is the following:
mediaPlayer = new MediaPlayer(); mediaPlayer.setOnCompletionListener(this); mediaPlayer.setOnErrorListener(this); mediaPlayer.setOnPreparedListener(this); mediaPlayer.setOnBufferingUpdateListener(this); mediaPlayer.setDataSource("a valid URL"); mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); mediaPlayer.prepareAsync();............................

* Support for OpenMAX encoders* Support for additional audio codecs in AuthorEngine* Improved buffering model supports shared buffers allocated in the decoder. but dont know how!

I have a activity which is called from another activity as an intent... This activity loads and starts playing a audio file. All is good - that much works. The activity also has a "stop" button and that stops the audio from playing - that is also fine.
But how do I stop the file from playing if the user uses the back button to leave the activity without clicking on the "Stop" button?

I've implemented "Audio Capture Setup and Start" example (http:// developer.android.com/guide/topics/media/index.html) with small modification - the output format is MPEG_4 not THREE_GPP.
The result - records with extremely poor audio quality.
Could you help me to understand where is error and how is possible to do really good audio records with Android?
I've done an experiment with Camcorder - standard Android application. Sound quality of the video is same poor. The audio signal is extremely low (quite).
Is it "by design" or may be some hardware problem (T-Mobile G1)?
I've found description similar problem here - http://osdir.com/ml/AndroidDevelopers/2009-06/msg00752.html - "Microphone audio capture with emulator is of very poor quality". In my case this problem reproduces on the real device. Unfortunately I have not found answer. I read about some "custom" encoders.. but have not found any example how implement them.

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:

Every time someone leaves me a voicemail on my home phone number, VOIP home phone voice mail box sends me the voicemail as a .wav file attachment. When I try to play this .wav file the phone refuses, saying "Sorry, the player does not support this type of audio file".
So, I take it the .wav files cannot be played on Android phones. Has anyone found a workable and simple workaround to this yet?

I am looking for an Android Audio Player that is based on a "now playing" playlist, like Amarok, Winamp or WMP. In relation with that playlist, I want buttons to add a song as the next song, or to add the song to the end of the playlist. Like the Rockbox firmware does it. Is there any app out there that works like this? I don't need any advanced features like lyrics, covers, etc, I just want to listen to music. In case there's nothing around, I'll even consider developing my own. Who needs synched lyrics if there's not even an "add next" option?

I'm using Meridian to listen to audio books, but I would sure love to find a player that let's me choose when to start listening. Meridian remembers where I left off in a book, but one slight bump and it goes back to zero. Sure would be nice to have it start at "minute 210" or wherever.

I am writing a music player for esoteric music formats, and have defined mime types for them in my Manifest.
However, the standard music player is always started even though it can't handle the format. Looking at logcat I see;
: D/MediaScannerService( 688): IMediaScannerService.scanFile: / sdcard/download/Cybernoid.sid mimeType: audio/prs.sid : I/ActivityManager( 578): Stopping service: com.android.providers.media/.MediaScannerService : I/ActivityManager( 578): Starting activity: Intent { action=android.intent.action.VIEW data=file:///sdcard/download/ Cybernoid.sid type=audio/prs.sid flags=0x4000000 comp={com.android.music/com.android.music.MediaPlaybackActivity} }
.. so it seems the component is explicitly set to the music player ? Is there any way around this ?

The dev guide suggests this
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(this, Uri.parse("http://wamu-1.streamguys.com:80"));
mp.prepare(); mp.start();
I can't seem to get it working though.
I'm getting "java.io.IOException: Prepare failed.: status=0x1"

As mentioned audio stops after some random number of times when played from either Music/Video player. After some debugging, I found that the problem is:
In "android_audio_output.cpp"->audout_thread_func() there is a call to wait(iAudioThreadSem->Wait()) just before the while(1) and it is waiting indefinitely for something.
Can anybody tell me what is it waiting for and why is it not able to come out? From what I can understand, it is waiting for a signal (semaphore) but where is it expecting a signal from?
