Hi in my android application I am using videoview for streaming my videos. I face very unwanted behaviour from my videoview. The scenario is like this. I have activity A and activity B. Activity A has one simple button and on click of that button I am starting activity B which contains videoview and starts playing video as soon as it start my activity. So my observation is like this: Once I start Activity B it will call setVideoURI and start(). there are few callback methods one of them is setOnPreparedListener. when I call start() after some time It is executing setOnPreparedListener and after that it will start playing video. But in between before executing setOnPreparedListener if I come back to Activity A it will block that activity UI for some time. But if I wait till setOnPreparedListener get executes and then come back to Activity A then its working properly. This is not happening with all devices only with google devices like moto g and nexus. But I tried with htc or intel device it is working properly. My code looks like :
VideoView mVideoView =(VideoView)findViewById(R.id.myVideo);
//Creating MediaController
MediaController mediaController= new MediaController(this);
mediaController.setAnchorView(mVideoView);
//specify the location of media file
Uri uri=Uri.parse("http://abcExample.com/playlist.m3u8");
//Setting MediaController and URI, then starting the videoView
mVideoView.setMediaController(mediaController);
mVideoView.setVideoURI(uri);
mVideoView.requestFocus();
mVideoView.start();
mVideoView.setOnErrorListener(new OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
Log.i("this is video view sample ... ", "this is video view sample ... this is on error listener ");
return true;
}
});
mVideoView.setOnPreparedListener(new OnPreparedListener()
{
#Override
public void onPrepared(MediaPlayer mp)
{
Log.i("this is video view sample ... ", "this is video view sample ... this is on prepared listener ");
}
});
mVideoView.setOnCompletionListener(new OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
Log.i("this is video view sample ... ", "this is video view sample ... this is on complete listener ");
}
});
Am I missing something or doing something wrong? Need some help. Thank you.
I'm having the same behaviour with videoview. I was looking for a solution but i didn't find anything. Maybe, It's possible that making a new task fix that issue. I'll try it

I'm using VideoView to loop a small video, all works fine on the emulators, but when I deploy that to TV, after the first loop video turns black, but sound keeps going. This is the code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
VideoView videoview = (VideoView) findViewById(R.id.videoview1);
Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.video);
videoview.setVideoURI(uri);
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
videoview.start();
}
});
}
The Emulator is using Android 6.0, the TV is Sony Bravia with Android 6.0.1.
I tested using SurfaceView, instead of VideoView - the same thing happens.
Any idea how to get rid of that black screen?
PS: There is a workaround that works - make OnCompletionListener and do videoview.start() there - this way it loops, but there's an ugly gap between the loops.
Just use this mVideoView.setZOrderOnTop(true); It will not show the black screen as the view appears.
Try to set your VideoView using handler like this.
videoview.setBackgroundColor(Color.WHITE); //color what you want as background
videoview.postDelayed(new Runnable() {
#Override
public void run() {
videoview.setVideoURI(videoUri);
}
}, 100);
videoview.postDelayed(new Runnable() {
#Override
public void run() {
vv.setBackgroundColor(Color.TRANSPARENT);
}
}, 300);
videoview.requestFocus();
videoview.start();
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { #Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});
I have looked into the source code of VideoView and the first thing that I would like to point out is that inside the setVideoURI() method the MediaPlayer object will be created, and the OnPreparedListener will be set.
Your mistake is that you set the OnPreparedListener after the MediaPlayer may already have prepared the video, thus never call the onPrepared in the listener you have set after that, which means the setLooping(true) was maybe never set on the MediaPlayer.
TL;DR:
Put videoview.setVideoURI(uri); after videoview.setOnPreparedListener().
videoview.start() should be after setVideoURI(). On finish it should start again without additional input because this time mp.setLooping(true); was correctly set and will be executed. No videoview.start() is necessary after the initial one.
I actually ended up using ExoPlayer instead of the default one.
It's a bit harder to set up, but this problem didn't show up there.
Good afternoon/morning! Hoping someone could help me out with a small problem I'm having. I'm playing a remote .mp3 file using a VideoView and a custom MediaController.
My MediaController looks like this:
public class MyMediaController extends MediaController {
public MyMediaController(Context context) {
super(context);
}
// Do nothing on the overridden hide method so the playback controls will never go away.
#Override
public void hide() {
}
// Override the dispatchKeyEvent function to capture the back KeyEvent and tell the activity to finish.
#Override
public boolean dispatchKeyEvent(KeyEvent event)
{
if (event.getKeyCode() == KeyEvent.KEYCODE_BACK)
{
((Activity) getContext()).finish();
}
return super.dispatchKeyEvent(event);
}
}
And my code to attach it to my VideoView looks like this:
VideoView videoView = (VideoView) findViewById(R.id.VideoView);
// Use our own media controller, which inherits from the standard one. Do this to keep
// playback controls from disappearing.
mediaController = new MyMediaController(this);
mediaController.setAnchorView(videoView);
Uri video = Uri.parse(URL);
videoView.setMediaController(mediaController);
videoView.setVideoURI(video);
// Set a handler that will show the playback controls as soon as audio starts.
videoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer arg0) {
mediaController.show();
}
});
videoView.start();
The problem I'm having is that when the .mp3 file starts playing, the control bar at the bottom has the "Play" button showing (i.e. triangle) instead of the "Pause" button (two parallel bars) even though the audio is already playing. Anyone know how to fix this?
EDIT 1:
I'd also be interested in any other solutions for playing a remote .mp3. The only requirements I have are that the user can pause/play the audio and also see what the name of the audio file (title) is.
Thank you!
Try This : It solved the Issue For Me.
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
mMediaController.show();
}
});
Simply:
#Override
public void onPrepared(MediaPlayer arg0) {
if (mediaController.isShowing==false) {mediaController.show();}
}
I'm playing video from raw folder. Generally once its completed it remains in same activity. how to return back to previous activity automatically without pressing back button?
Are you using a VideoView to play the video in your 2nd activity? If so, you can use the OnCompletion event to call finish() on the activity, which will return you to the 1st activity.
Something like this should work:
VideoView videoView = (VideoView) findViewById(R.id.videoView);
videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer player) {
Log.i("VideoView", "onCompletion()");
finish();
}
});
Just be sure to replace R.id.videoView with the actual id in your layout file.
Hope that helps!
Use MediaPlayer.OnCompletionListener to Listen when Video Playing in finished in Activity 2 and start Previous activity on onCompletion as :
videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
//start Previous Activity here
Current_Activity.this.finish();
}
}); // video finish listener
After playing a video onCompletion() method is invoked, in that just call finish() method in it.
I have used MediaController in my activity its working fine but when I play video for first time then there should b pause button visible but instead there is play and when I press that button then the video is paused correctly and state remains the same and after that its working properly. And same thing happens when Video Completed.
Is this a bug or I am doing any thing wrong?
videoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaController = new MediaController(VideoPlayerActivity.this){
public void hide(){
}
public void show(){
if(isPlayingAd){
super.hide();
}else{
super.show();
}
}
};
videoView.setMediaController(mediaController);
mediaController.setMediaPlayer(videoView);
mediaController.show();
}
});
I've been having the same issue. I was not calling MediaController.setVideoView as you were, as I thought VideoView.setMediaController was sufficient for wiring things up. I tried adding that, then moving the call to show within onPrepared, and now it is working.
I wish I had a better understanding; my best guess is that perhaps everything needs to be wired up properly before the media is prepared, and before calling show. In any case, here is what I have:
mMediaController = new MediaController(VideoPlayerActivity.this, false);
mVideoView.setOnPreparedListener( new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer pMp) {
mMediaController.show();
}
});
mVideoView.setMediaController(mMediaController);
mMediaController.setMediaPlayer(mVideoView);
mVideoView.setVideoPath(uri); // may not be applicable in your case
mVideoView.requestFocus();
mVideoView.start();
As Oneworld mentioned on the other answer, I had same issue with old Samsung devices. Even though MediaController wired with VideoView properly, play button loses its sync until pause and play again with MediaController.
This thing seems only happens on old Samsung devices(KitKat and below i guess).
The only solution I found was play video programmically by videoview.start() before showing controller by mc.show().
I have the following code to take a video as a raw resource, start the video and loop it but I need the video to loop seamlessly as of now when it comes to an end of the clip and starts the clip again the transition between causes a flicker for a split second, which I really can't have for my app.
public class Example extends Activity {
VideoView vv;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
vv = (VideoView)findViewById(R.id.VideoView01);
//Video Loop
vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
vv.start(); //need to make transition seamless.
}
});
Uri uri = Uri.parse("android.resource://com.example/"
+ R.raw.video);
vv.setVideoURI(uri);
vv.requestFocus();
vv.start();
}
}
The clip is only 22 seconds long but was created to be seamless so it is possible to work without the delay.
Try this it will work 100%
VideoView videoView;<---write this in outside of method or else declare it as final variable.
videoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});
In Kotlin simply use
videoView.setOnPreparedListener { it.isLooping = true }
Not sure if this helps years later, but I used
vv.start();
vv.setOnCompletionListener ( new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
vv.start();
}
});
and it has a seamless loop
The pause is for the underlying MediaPlayer to refresh its buffers. How long that will take will depend on a number of factors, many of which are outside your control (e.g., speed of CPU, speed of on-board flash storage).
One you can control is to get your video out of the resource and into the filesystem. Resources are stored in the APK, which is a ZIP file, so extracting the video this way probably takes extra time.
You may need to switch away from VideoView and use a SurfaceView with two MediaPlayers, alternating between them -- one is playing while the next is preparing, so when the playing one ends you can switch to the new player. I have not tried this, and so I do not know what the ramifications might be. However, I know that this technique is frequently used for audio playback to transition from one clip to another.
Little late, but any reason that you can't use the following?
MediaPlayer.setLooping(true);
If you are using Kotlin
videoView.setOnPreparedListener(object : MediaPlayer.OnPreparedListener {
override fun onPrepared(mp: MediaPlayer?) {
//Start Playback
videoView.start()
//Loop Video
mp!!.isLooping = true;
Log.i(TAG, "Video Started");
}
});
Using Arrow Expression short form
videoView.setOnPreparedListener { mp ->
//Start Playback
videoView.start()
//Loop Video
mp!!.isLooping = true;
Log.i(TAG, "Video Started");
};
Answer to this is to remove the audio from the video and convert that to a .ogg file which can be looped seamlessly and then use the video without audio to loop round and this works.
Here is answer friends, you must use vv.resume in setOnCompletionListener class
