    <p>I am having trouble over streaming of wav audio files with androids MediaPlayer.</p> <p>The URL for wave files are verified and downloaded separately on device successfully. Those downloaded files plays with no issue, but when same file is streamed to the player, it won't play at all and gives error.</p> <pre><code>01-18 09:25:00.963: E/MediaPlayer(8825): error (1, -4) 01-18 09:25:00.963: W/System.err(8825): java.io.IOException: Prepare failed.: status=0x1 01-18 09:25:00.963: W/System.err(8825): at android.media.MediaPlayer.prepare(Native Method) 01-18 09:25:00.963: W/System.err(8825): at com.movivation.wavetrial.AudioPlayer.playMedia(AudioPlayer.java:174) 01-18 09:25:00.963: W/System.err(8825): at com.movivation.wavetrial.AudioPlayer.onCreate(AudioPlayer.java:92) 01-18 09:25:00.963: W/System.err(8825): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 01-18 09:25:00.963: W/System.err(8825): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2633) 01-18 09:25:00.963: W/System.err(8825): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2685) 01-18 09:25:00.963: W/System.err(8825): at android.app.ActivityThread.access$2300(ActivityThread.java:126) 01-18 09:25:00.963: W/System.err(8825): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2038) 01-18 09:25:00.963: W/System.err(8825): at android.os.Handler.dispatchMessage(Handler.java:99) 01-18 09:25:00.963: W/System.err(8825): at android.os.Looper.loop(Looper.java:123) 01-18 09:25:00.963: W/System.err(8825): at android.app.ActivityThread.main(ActivityThread.java:4633) 01-18 09:25:00.963: W/System.err(8825): at java.lang.reflect.Method.invokeNative(Native Method) 01-18 09:25:00.973: W/System.err(8825): at java.lang.reflect.Method.invoke(Method.java:521) 01-18 09:25:00.973: W/System.err(8825): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) 01-18 09:25:00.973: W/System.err(8825): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) 01-18 09:25:00.973: W/System.err(8825): at dalvik.system.NativeStart.main(Native Method) 01-18 09:25:00.973: I/MediaPlayer(8825): Info (1,26) </code></pre> <p>My code to play the file:</p> <pre><code>private void playMedia(boolean isWebUrl) { mPlayer = new MediaPlayer(); mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); mPlayer.setOnCompletionListener(new OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { Log.d(tag, "Ending thread"); isPlaying = false; if (pd != null) { pd.dismiss(); } } }); mPlayer.setOnPreparedListener(new OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { Log.d(tag, "starting"); mPlayer.start(); mSeekbar.setProgress(0); mSeekbar.setMax(mPlayer.getDuration()); Log.d(tag, "seek started"); new PlayAsync().execute(); } }); mSeekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { @Override public void onStopTrackingTouch(SeekBar seekBar) { } @Override public void onStartTrackingTouch(SeekBar seekBar) { } @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { if (fromUser) { mPlayer.seekTo(progress); mSeekbar.setProgress(progress); } } }); try { if (isWebUrl) { Log.d(tag, "playing tmp file"); mPlayer.setDataSource(url); } else { File f = new File(fileurl); FileInputStream fis = new FileInputStream(f); mPlayer.setDataSource(fis.getFD()); } Log.d(tag, "calling prepare"); mPlayer.prepare(); //originally i use prepareAsync() } catch (IllegalArgumentException e) { e.printStackTrace(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } </code></pre> <p>The file I am trying to play is actually a wave file, and I have not found any concrete statement about the error mentioned above.</p> <p>Any pointer regarding streaming of wave or the error itself would be highly appreciated.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
