I'm developing a video application. After 1st video playback done, in the "OnCopletion" I'm trying to start a new one. But it just stops (not crashes) and do nothing. In the log:
10-19 09:44:49.056: ERROR/MediaPlayer(4654): setDataSource called in state 128 10-19 09:44:49.056: WARN/System.err(4654): java.lang.IllegalStateException 10-19 09:44:49.056: WARN/System.err(4654): at android.media.MediaPlayer.setDataSource(Native Method) 10-19 09:44:49.056: WARN/System.err(4654): at ru.osiris.BusAdvertising.BusAdvertisingActivity.onCompletion(BusAdvertisingActivity.java:1255) 10-19 09:44:49.056: WARN/System.err(4654): at android.media.MediaPlayer$EventHandler.handleMessage(MediaPlayer.java:1304) 10-19 09:44:49.056: WARN/System.err(4654): at android.os.Handler.dispatchMessage(Handler.java:99) 10-19 09:44:49.056: WARN/System.err(4654): at android.os.Looper.loop(Looper.java:123) 10-19 09:44:49.056: WARN/System.err(4654): at android.app.ActivityThread.main(ActivityThread.java:4627) 10-19 09:44:49.056: WARN/System.err(4654): at java.lang.reflect.Method.invokeNative(Native Method) 10-19 09:44:49.056: WARN/System.err(4654): at java.lang.reflect.Method.invoke(Method.java:521) 10-19 09:44:49.056: WARN/System.err(4654): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 10-19 09:44:49.056: WARN/System.err(4654): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 10-19 09:44:49.056: WARN/System.err(4654): at dalvik.system.NativeStart.main(Native Method) what does it mean? How can I fix it? there is my code:
public class BusAdvertisingActivity extends Activity implements LocationListener, OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener, OnVideoSizeChangedListener, SurfaceHolder.Callback { ... private MediaPlayer mMediaPlayer; private SurfaceView mPreview; private SurfaceHolder holder; private String path; private Bundle extras; @Override public void onCreate(Bundle icicle) { mPreview = (SurfaceView) findViewById(R.id.surface); holder = mPreview.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); extras = getIntent().getExtras(); } public void surfaceCreated(SurfaceHolder holder) { Log.d(TAG, "surfaceCreated called"); playVideo(); } private void playVideo(Integer Media) { Log.d(TAG, "playVideo called"); doCleanUp(); try { File clip=new File(Environment.getExternalStorageDirectory(), playList[FLcurrentVideo].substring(2, playList[FLcurrentVideo].length()-1)+".mp4"); path = clip.getAbsolutePath(); mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(path); mMediaPlayer.setDisplay(holder); mMediaPlayer.prepare(); mMediaPlayer.setOnBufferingUpdateListener(this); mMediaPlayer.setOnCompletionListener(this); mMediaPlayer.setOnPreparedListener(this); mMediaPlayer.setOnVideoSizeChangedListener(this); mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); } catch (Exception e) { Log.e(TAG, "error: " + e.getMessage(), e); } } public void onCompletion(MediaPlayer arg0) { Log.d(TAG, "onCompletion called"); FLcurrentVideo++; File clip=new File(Environment.getExternalStorageDirectory(), playList[FLcurrentVideo].substring(2, playList[FLcurrentVideo].length()-1)+".mp4"); path = clip.getAbsolutePath(); try { Log.d ("111", path); arg0.setDataSource(clip.getAbsolutePath()); //I got exception here arg0.setDisplay(holder); arg0.prepare(); arg0.setOnBufferingUpdateListener(this); arg0.setOnCompletionListener(this); arg0.setOnPreparedListener(this); arg0.setOnVideoSizeChangedListener(this); arg0.setAudioStreamType(AudioManager.STREAM_MUSIC); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IllegalStateException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } Please, help me.
