问题 I am having a tough time displaying the current track playing from a streaming source. Using MediaMetaDataRetriever class returns a NULL, meaning it failed. I wrote a simple method but now I'm inclining to think this only works on media files like MP3, WMA, AVI, etc. public void metaData(){ mmr.setDataSource(urlStation); String metaD = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ALBUMARTIST); Toast.makeText(MainActivity.this, "Artist = " + metaD, Toast.LENGTH_LONG).show(); Any

问题 I've tried settings the audio stream of the media player in my application using the following code but when I do this I hear no sound in the emulator. If I don't set the stream for the player then the audio plays fine. I'm sure I'm using this wrong but cannot workout how, any help? MediaPlayer player = MediaPlayer.create(getApplicationContext(), R.raw.test_audio); AudioManager audioManager = (AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE); audioManager

问题 I am working on a media player app. I am trying to sync it to a seekbar so that when media is played the seek bar progresses automatically. Here is my source code: public class MusicDroid extends ListActivity implements SeekBar.OnSeekBarChangeListener, Runnable { private int cur_time = 0; private SeekBar seekbar; int song_dur = 0; GroveService gs; public Chronometer timer; int timer_time = 0; @Override public void onCreate(Bundle icicle) { try { super.onCreate(icicle); setContentView(R.layout

问题 I'm building video player with android media player object. i'm able to hear the audio but the video does not appear on surfaceView. here is my code public class PlayerActivity extends Activity implements SurfaceHolder.Callback { String path; private MediaPlayer mp; private SurfaceView mPreview; private SurfaceHolder holder; boolean pausing = false; public static String filepath; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R

问题 I can play the videos fine back to back by implementing the OnCompletionListener to set the data source to a different file. No problems there. I call reset() and prepare() just fine. What I haven't been able to figure out, is how to get rid of the 1-2 second gap screen flicker between the data source change and the new video starting.

问题 I use MediaPlayer for playing a single mp3 song from network. Data source is a HTTP URL. Let's assume we have following playing state. Song duration: 1:00 Current progress: 0:10 Current buffering progress 0:30 Let's say I want to skip some part of a song and seek forward. I do it with MediaPlayer.seekTo() method. If I seek to buffered position (0:20) it is performed correctly. But if I seek to a position which has not been buffered yet (0:40) the MediaPlayer behaves odd. It indicates

问题 I am new to android programming and have found myself stuck I have been researching various ways to stream live video from phone to phone and seem to have it mostly functional, except of course the most important part: playing the stream. It appears to be sending the stream from one phone, but the second phone is not able to play the stream. Here is the code for the playing side public class VideoPlayback extends Activity implements Callback { MediaPlayer mp; private SurfaceView mPreview;
