Android MediaPlayer seekTo() function working incorrect

I have a problem when using MediaPlayer to play video from url.
The follow of program : create an activity to play video -> press Home button -> back to app.
The requirement is video play from start, when press Home button video continuos play(only audio), and when back to app, video must play continuous(combine movie and audio).
The first, I created a MediaPlayer variable to play video. When Home button is pressed, MediaPlayer play continuous. But when back to app, video cannot displayed(black screen). So, I created other MediaPlayer variable to solved this issue. But when I using seekTo() function to seek second MediaPlayer to position of first MediaPlayer, this function is working incorrect.

play Video in VideoView

In my activity I am trying to play a video which is stored in raw folder. below is my activity.
In the first button I am not getting error also like can't play this video, but only black screen appears. while clicking the second button I am getting a message that can't play this video. below is my activity

mc.setAnchorView(vv);
cse.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
vv.setVideoURI(Uri.parse("android.resource://com.example.college/"+R.raw.c));
vv.start();
}
});
it.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
vv.setVideoURI(Uri.parse("android.resource://com.example.college/"+R.raw.k));
vv.start();
}
});
ece.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
vv.setVideoURI(Uri.parse("android.resource://com.example.college/"+R.raw.a));
vv.start();
}
});
eee.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
vv.setVideoURI(Uri.parse("android.resource://com.example.college/"+R.raw.s));
vv.start();
}
});
}
}

The code is correct. All the errors are related to video resolution.
I have replaced video with different resolution , and it is working

Android MediaPlayer - onBackPressed() not working

I have an app which just plays the same video in loop. Everything works as expected, except for one thing:
I want to stop the playback if I press the back button, but I am not able to get it to work. My activity simply ignore that I press it and instead I get an ANR. I thought that using onBackPressed() should handle this case.
Can anyone tell me, what I am doing wrong???

Call super.onBackPressed(); before your code in onBackPressed(..)

#Override
public void onBackPressed() {
super.onBackPressed();
System.out.println("onBackPressed() called");
releaseMediaPlayer();
}
Just call super.onBackPressed before releasing media player.
EDIT:
Also try removing the
mMediaPlayer=null;
statement in your releaseMediaPlayer() method.

I don't think anyone can help you - unless you post your code fully. There are so many things missing...Your OnTouchListener doesn't even check for touch events such as ACTION_DOWN, ACTION_MOVE or anything else.

I would suggest that you take the action when user taps i.e.
public boolean onTouch(View v, MotionEvent event) {
switch(event.getAction())
{
case MotionEvent.ACTION_DOWN:
// Do your firing even
break;
case MotionEvent.ACTION_UP:
//action when user removes finger.
break;
default:
return false;
} // end of switch case
return true;
}
Also, just add a break point in onTouch() and debug to know what is happening and what part is not executing and fix it accordingly.

I changed it this way, but every time the animation starts from 0, there is a way to continue an action and does not stop and start it again?

setBackgroundResource of TextView in listitem

I've got an activity that presents a listview of tracks of songs. When an item is clicked, it streams the appropriate media file. I have a textview in each row that displays the length of the track. When the track is playing, I switch the backgroundresource of the textview in the row to a pause button drawable. In other words, when it's ready to play, it displays a play button and when its currently playing it displays a pause button. Simple enough....
Currently, I'm doing something like this to set the drawable to pause button if the mediaplayer is playing:
if(mp.isPlaying()) {
_player.setBackgroundResource(R.drawable.pausebtn);
_player.setText(" :" + String.valueOf(mp.getDuration()/1000));
I'm doing this in my Runnable which has the mediaplayer callback of onPrepared.
Problem is that I need the drawable to be set in THAT list item, i.e. the one which was clicked and whose track is being played. How can I grab hold of which one was clicked and set ITS textview to the new drawable?
Here's the full code:

As you can see, my inner class AudioCell which extends RelativeLayout is what I'm using for the rows of my ListView....
Any thoughts? Where should I be setting the drawable and how can I make sure it does it only for the row that was clicked (i.e. for the track that's actually being played).

change the TrackClicked method's siggnature. pass both arg1 and arg3 from onItemClick and in the TrackClicked method do this arg1.setBackgroundResource(R.drawable.thebackground);

Inside your TrackClicked method, add this:
getAdapter().getChildAt(arg2).setBackgroundResource(R.drawable.thebackground);
