Androids MediaPlayer plays the video every second time.

Question

I am writing an application in which one of the actions could play video files. I record a video, but then when I try to start the game. The activity starts and the video plays for the first time. Then I press the "Back" button, return to the previous step, select a video (same or different), and the video will start playing again, all the views (buttons, icon, etc.) are shown, but the video is not displayed. I come back again, select the video, open the video and play the video again. Therefore, he plays every second time. I tried to debug, but could not find what the problem was and any help would be greatly appreciated. The following is the opcode as well as the output of logCat from eclipse.

public class FightPlayerActivity extends Activity implements OnSeekBarChangeListener, SurfaceHolder.Callback, OnPreparedListener { private MediaPlayer mp=null; private SeekBar seekBar; private String filePath; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Toast.makeText(this,"Create ", 2000).show(); setContentView(R.layout.fight_player); filePath=getIntent().getStringExtra("filename"); filePath=Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)+"/FightAll_BJJ_Scoring/"+filePath; Toast.makeText(this,filePath, 2000).show(); // seek bar seekBar=(SeekBar) findViewById(R.id.seek_bar); seekBar.setOnSeekBarChangeListener(this); try { SurfaceView sv=(SurfaceView) findViewById(id.video_preview); SurfaceHolder sh=sv.getHolder(); sh.addCallback(this); sh.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SecurityException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IllegalStateException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { // TODO Auto-generated method stub } public void onStop(View view) { super.onStop(); mp.stop(); mp.reset(); mp.release(); } public void onStart(View view) { super.onStart(); } public void stop(View view) { mp.stop(); } public void pause(View view) { mp.pause(); } public void play(View view) { mp.start(); } public void surfaceCreated(SurfaceHolder holder) { try { mp=new MediaPlayer(); mp.setDataSource(filePath); mp.setDisplay(holder); mp.setOnPreparedListener(this); mp.setAudioStreamType(AudioManager.STREAM_MUSIC); mp.prepare(); } catch (IllegalStateException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public void surfaceDestroyed(SurfaceHolder holder) { // TODO Auto-generated method stub } public void onPrepared(MediaPlayer mediaplayer) { mp.start(); seekBar.setMax(mp.getDuration()); } public void onProgressChanged(SeekBar sb,int progress,boolean fromUser) { //Toast.makeText(this, progress, 2000).show(); mp.seekTo(progress); } public void onStartTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub onProgressChanged(seekBar,seekBar.getProgress(),true); } public void onStopTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } 

and write down below:

Answer 1

Solved .. If I would move the initialization code from onCreate () to onStart () and remove the “View view” from onStart ().
