I have some pretty simple Soundboard applications on the Android Market that work flawless on an LG Ally, the Motorola Droid, and the Nexus One, but I recently received an e-mail from a user with the Motorola DroidX claiming that most of the sounds do not work. I've exchanged a few e-mails with him. He claims the Soundboard is the only application running, and he's double checked to make sure that the Media Volume wasn't set to minimum. I really don't have access to one either to play around with. The application isn't doing anything cosmic to play the sounds. Below is a code snippet. Any insights into what might be causing the hang up are greatly appreciated.
public void play(Sample sample) {
Log.v(TAG, "Playing: " + getString(sample.getButtonTextResId()) + " (" + sample.getSoundResId() + ")");
if (mPlayer != null) { mPlayer.stop(); mPlayer.release();
} MediaPlayer player = MediaPlayer.create(this, sample.getSoundResId());
mPlayer = player; if (player != null) { player.setVolume(1.0f, 1.0f);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override public void onCompletion(MediaPlayer mp) { mp.release();
mPlayer = null; } } ); player.start(); } }
I just started with creating my own media player application by looking at the code samples given in Android SDK. While I am trying to play a local media file (m.3gp), I am getting IOException error :: error(1,-4).

View 2 Replies View RelatedI have an Activity that plays a brief OGG "pop" sound effect when bubbles pop. To keep it fast and to ensure I can play several pops, I create four MediaPlayer instances. I synchronize access to a pool of instances, so I can play up to four pops at once. Once a sound completes, I call seekTo(0) and return the MediaPlayer instance to my pool.
Here is a rough sketch of the code:
// when the activity resumes... for (int i=0; i<4; i++) {
MediaPlayer mp = MediaPlayer.create(context, R.raw.pop);
mp.setOnCompletionListener(this);
mp.setVolume(1f, 1f); players.add(mp); // put into a pool of available players }
I'm trying to play a playlist I get using the MediaStore provider. However, when I try playing a playlist nothing happens. Can a MediaPlayer play a playlist (m3u file) and do I need to set the first track to play? This is my test code in the onCreate() method:
Uri uri = MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI;
if(uri == null) { Log.e("Uri = null");
} String[] projection = new String[] { MediaStore.Audio.Playlists._ID,
MediaStore.Audio.Playlists.NAME, MediaStore.Audio.Playlists.DATA };
Cursor c = managedQuery(uri, projection, null, null, null);
if(c == null) { Toast.makeText(getApplicationContext(),
R.string.alarm_tone_picker_error, Toast.LENGTH_LONG).show();
return; } if(!c.moveToFirst()) { c.close();
Toast.makeText(getApplicationContext(), R.string.alarm_tone_picker_no_music,
Toast.LENGTH_LONG).show(); return; } c.moveToFirst(); try {
MediaPlayer player = new MediaPlayer(); player.setDataSource(c.getString(2));
player.start(); } catch(Exception e) { e.printStackTrace(); }
I have turned on every volume stream.
I have an application that I developed using the Android 1.1 SDK that I am trying to port to Android 1.5. In my application, I record a sound through the microphone and then do various things with it, including playing it back using a MediaPlayer object. My code works fine when I use the 1.1 target, but when I use a 1.5 target I get this error when setting up the player:
Command PLAYER_SET_DATA_SOURCE completed with an error or info PVMFErrNotSupported error (1, -4) Couldn't setup MediaPlayer java.io.IOException: Prepare failed.: status=0x1 at android.media.MediaPlayer.prepare(Native Method) at org.byu.chum.AudioUtils.AudioRecording.stopRecording (AudioRecording.java:92) at org.byu.chum.SoundRecorder.Recorder$StopListener.onClick (Recorder.java:198)...
It seems like Android isn't liking the format of my media, but I don't know why, since I just recorded that very format on the Android device. Here's the code that is throwing the error:
player = new MediaPlayer();
try { player.setDataSource(recordFile.toString());
player.prepare(); } catch (IOException e) { Log.e("playRecording", "Couldn't setup MediaPlayer", e); }
I am unable to use the following to code to play multiple sounds/beeps simultaneously. In my onclicklistener I have added
... public void onClick(View v) { mSoundManager.playSound(1);
mSoundManager.playSound(2); } ...
But this plays only one sound at a time, sound with index 1 followed by sound with index 2. How can I play atleast 2 sounds simultaneously using this code whenever there is an onClick() event?
public class SoundManager {
private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;
public SoundManager() {
} public void initSounds(Context theContext) {
mContext = theContext; mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
} public void addSound(int Index,int SoundID)
{ mSoundPoolMap.put(1, mSoundPool.load(mContext, SoundID, 1));
} public void playSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
} public void playLoopedSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f);
} }
Shown are a few lines of code. If I play a single sound, it runs fine. Adding a second sound causes it to crash.
private SoundManager mSoundManager;
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.sos);
mSoundManager = new SoundManager(); mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1,R.raw.dit); mSoundManager.addSound(1,R.raw.dah);
Button SoundButton = (Button)findViewById(R.id.SoundButton);
SoundButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) { mSoundManager.playSound(1);
mSoundManager.playSound(2); } } ); }

In my android game I want to have a rhythm Mediaplayer object and a lead Mediaplayer object playing in sync. However at the moment the rhythm is a slight bit behind the playback of the lead Mediaplayer object. Is there a way I can make it so that both are started at the same time, for instance using Runnables etc?!It's quite crucial that they play in sync with each other as you can imagine!

View 8 Replies View RelatedI am new to using Android. I am wondering if there is any video (MP4) player that would continue playing the video even when I use the home button to switch to other apps (e.g. check my email etc.) I have a few documentaries/discussions to watch and sometimes minimize the video player to check other information on my phone and the video stops.
Any Video players that continue playing when minimized. I know that the Meridian Player continues playing when the screen is switched off, but it stops if you press the home button.
(I use a Galaxy Nexus with Jelly Bean.)
How do you block Android game files from adding themselves to your media players? For example, if you're using Moboplayer to view the pics and vids you've shot with your camera, and you have a game like Dragon's Lair that has hundreds of mini 3 mB vid clips on your device to play the game, when I try to view my personal videos, I have to filter through the 800 some odd game vid clips just to look at my home videos. To add insult to injury, if you use a backup like Verizon that backs up only your newest movies and pics, it also downloads these hundreds of vid clips as well as photos of the uniforms on a game like Home Run Battle.

View 3 Replies View RelatedI'm playing some MediaPlayer instances at the same time (4 or 5) but sometimes when I try to start a new media player it doesn't work and an error is shown on the log:
E/AudioFlinger( 1073): no more track names availlable E/AudioTrack( 1073): AudioFlinger could not create track, status: -12 E/AudioSink( 1073): Unable to create audio track E/VorbisPlayer( 1073): mAudioSink open failed
It also happens when there're only 3 or 2 MediaPlayer playing at the same time. What does it mean this error? How can I workaround with it? Actually checking the isPlaying() after the start() call does not seem very helpful as every call returns true. I've to say that every MediaPlayer is created once via MediaPlayer.create.
I noticed that you can't adjust media volume without first playing media. Like you have to, for example, press the play button before pressing rocker volume in order to adjust media volume or else you'll just be adjusting ringer volume. This is unfortunate since games also use media volume. So if you wonna start up a quick game in a quiet setting, your in trouble if you were listening music before and never turned down/off the media volume. Unless I'm missing something and there is in fact a way to do it?
