Android play video in surfaceview NullPointerException

Android play video in surfaceview NullPointerException - android

I try to play video in surfaceview. I use Fragment (extends Fragment) and I have NullPointerException. I have no idea what am I doing wrong. First time I used Activity and in Activity project worked perfect but I use Fragment and I have error
This is a my source

Error log

It seems that onSurfaceCreated is called before playVideo(). Initialize your mMediaPlayer (and handler too by the way) in Fragment's onCreate().
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
handler = new Handler();
playVideo();
}
private void playVideo() {
mcontroller = new MediaController(getActivity());
mcontroller.setVisibility(View.INVISIBLE);
mMediaPlayer = MediaPlayer.create(getActivity(), Uri.parse(video));
// implement a fallback mechanism if it fails, for example if no internet or 404
if (mMediaPlayer == null) {
Log.w("Layout1", "Faileded to create MediaPlayer");
return;
}
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setScreenOnWhilePlaying(true);
mMediaPlayer.setOnVideoSizeChangedListener(this);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_layout1, null);
SurfaceView v = (SurfaceView) view
.findViewById(R.id.screen_tutorial_video_surface);
v.getHolder().addCallback(this);
return view;
}
#Override
public void surfaceCreated(SurfaceHolder arg0) {
if (mMediaPlayer == null) {
// implement a fallback mechanism if it fails, for example if no internet or 404
Log.w("Layout1", "MediaPlayer was not created");
return;
}
// the holder reference is already passed as arg0 here
mMediaPlayer.setDisplay(arg0);
try {
// progressDialog.dismiss();
mMediaPlayer.start();
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
After you removed catch (Exception e) in playVideo()
If you looked closely in logs you could have seen
Permission failure: android.permission.INTERNET from uid=10052 pid=1129
Request requires android.permission.INTERNET
Unable to create media player
create failed:
java.io.IOException: setDataSource failed.: status=0x80000000
Thus you also need to add permission
<uses-permission android:name="android.permission.INTERNET"/>
If it wasn't for the project you've attached we would never knew.

Android MediaPlayer with SurfaceView Fails on Prepare() Method

I am trying to build a video player using surface view and media player. My data source is an online video and I have enabled internet permission in manifest.
However, the video does not pay but throws a warning about prepare method without any hint at what the problem is like below:
W/System.err: at android.media.MediaPlayer._prepare(Native Method)

private static final String TAG = MainActivity.class.getSimpleName();
private SurfaceView surfaceView;
private ImageView playIV, backIV;
private TextView videoNameTV;

private SurfaceHolder holder;

}
Can anyone help me to figure this out? Thanks.

Use mediaplayer object which is being defined globally.
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}

How about this?
#Override
public void surfaceCreated(SurfaceHolder holder) {
mediaPlayer.setDisplay(holder);
try {
mediaPlayer.setDataSource(VIDEO_URL);
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.prepareAsync();
} catch (IOException e) {
e.printStackTrace();

How do i setMediaPlayer inside of a fragment?

I have a fragment where i am using media player and using my own custom controller class. I am not being able to set controller.setMediaPlayer inside fragment. I have implemented VideoControllerView.MediaPlayerControl class in fragment.
My fragment class is :

private Context context;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_home, container, false);
ButterKnife.bind(this, v);
player = new MediaPlayer();
controller = new VideoControllerView(getActivity());
SurfaceHolder videoHolder = videoSurface.getHolder();
videoHolder.addCallback(this);
progressBar.setVisibility(View.VISIBLE);
playVideo("http://202.166.200.170:8081/otv/aastha.stream/playlist.m3u8");
relativeLayout.setOnClickListener(new View.OnClickListener() {

if you see inside playVideo method inside setOnpreparedListener i am getting error in controller.setMediaPlayer() because i am not being able to pass the context here.
what can be done here to solve the error?

This is how we can use controller.setMediaPlayer()
// Implement MediaPlayer.OnPreparedListener
#Override
public void onPrepared(MediaPlayer mp) {
controller.setMediaPlayer(this);
controller.setAnchorView((FrameLayout)
findViewById(R.id.videoSurfaceContainer));
player.start();
}
// End MediaPlayer.OnPreparedListener
This is example to use costume controller

If you want, you could get the context from there using HomeFragment.this.getContext(), like:
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
controller.setMediaPlayer(HomeFragment.this.getContext());
controller.setAnchorView((FrameLayout) getActivity().findViewById(R.id.videoSurfaceContainer));
player.start();
progressBar.setVisibility(View.GONE);
if (relativeLayout.isShown())
relativeLayout.setVisibility(View.GONE);
}
});

I just moved controller.setMediaPlayer(this); to onCreateView and it worked.

Play/Pause Media Player in Texture View Surface Texture Listener

I've implemented a recycler view and each item will play video. My problem is that I need to pause/play the video when it scrolls on/off the screen.
I've implemented that when the user scrolls the video keeps playing.
I have had an issue trying to keep track of the media player when the view scrolls off screen.
I have come up with a solution and I'm hoping I can get some advice to see if may be any issues with the solution.
So I'm using a texture view to display the media player in the recycler view as videoviews aren't compatible when looking to use a recycler or customise the controller.
So in the surface texture destroyed (signalling that the view has left the screen) I pause the media player and when the surfacetexture is available (signalling the view is on screen) I check if the media player is null (as it will be when the screen first loads) if not I start the media player. Below is my video player class in where you can see my implementation.

Playing audio file in android

I got stuck with one requirement i need to play a media file in android.I will post the screen shot of the page
Actual requirement is the user wants to play the audio file in his recordings list.The recordings list are shown through list adapter.I want to display the play progress of the audio file on the same page(as like shown in the screen shot).
Iam pasting the code which i have tried.
public class RecordingActivity extends ListActivity implements MediaPlayerControl {
MediaPlayer mMediaPlayer;
MediaController mMediaController;
Handler mHandler;
String OUTPUT_FILE;
RelativeLayout rl;
Context context = null;
Point p;
static final String[] recordings = new String[] {"Example1","Example2",
"Example3","Example4","Example5" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new FirstAdapter(this, recordings));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
showPopup(RecordingActivity.this, p);
// get selected items
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mHandler = new Handler();
mMediaController.setMediaPlayer(RecordingActivity.this);
OUTPUT_FILE = Environment.getExternalStorageDirectory()+"/recorder.mp3";
try{
mMediaPlayer.setDataSource(OUTPUT_FILE);
mMediaPlayer.prepare();
}
catch(Exception e){
}
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mHandler.post(new Runnable() {
public void run() {
mMediaController.show(10000);
mMediaPlayer.start();
mMediaController.setEnabled(true);
}
});
}
});
}
private void showPopup(final Activity context, Point p) {
int popupWidth = 200;
int popupHeight = 150;
// Inflate the popup_layout.xml
RelativeLayout viewGroup = (RelativeLayout) context.findViewById(R.id.reviewlist);
LayoutInflater layoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.activity_play, viewGroup);
// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(popupWidth);
popup.setHeight(popupHeight);
popup.setFocusable(true);
// Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
int OFFSET_X = 30;
int OFFSET_Y = 30;
// Clear the default translucent background
popup.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
popup.showAtLocation(layout, Gravity.NO_GRAVITY,p.x+OFFSET_X,p.y+OFFSET_Y);
// Getting a reference to Close button, and close the popup when clicked.
ImageButton close = (ImageButton) layout.findViewById(R.id.close);

#Override
public void start() {
mMediaPlayer.start();
mMediaController.show();
}
#Override
public boolean onTouchEvent(MotionEvent event) {
mMediaController.show();
return false;
}
}
The problem am facing is i am able to play the audio file ,but it is not showing any popup layout.

Media player
MediaPlayer mp = new MediaPlayer();
// Set data source -
setDataSource("/sdcard/path_to_song");
// Play audio
mp.start();
// Pause audio
mp.pause();
// Reset mediaplayer
mp.reset();
// Get song length duration - in milliseconds
mp.getDuration();
// Get current duration - in milliseconds
mp.getCurrentDuration();
// Move song to particular second - used for Forward or Backward
mp.seekTo(positon); // position in milliseconds
// Check if song is playing or not
mp.isPlaying(); // returns true or false
Hope this will give you some solution. Refer this link. It will solve your problem

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mMediaController.setMediaPlayer(PlayAudioActivity.this);
mMediaController.setAnchorView(findViewById(R.id.audioView));
String audioFile = "" ;
try {
mMediaPlayer.setDataSource(audioFile);
mMediaPlayer.prepare();
} catch (IOException e) {
System.out.println("Error in playing audio");

public void onPrepared(MediaPlayer mp) {
mHandler.post(new Runnable() {
public void run() {
mMediaController.show(10000);
mMediaPlayer.start();
}

if you have done this then.

prepareAsync of MediaPlayer in one Activity, play in another

I am developing an application that, among other things, plays some video files (streaming). I would like to prepare the MediaPlayer in one activity but play the video once it is ready in another activity, so that the user can navigate through the content of the first activity to kill some time. Is this possible?
There is an static MediaPlayer defined in the Application class, like this:
public class EGDF_App extends Application {
private static MediaPlayer mediaPlayer = null;
public static MediaPlayer getMediaPlayer() {
if(mediaPlayer == null)
return new MediaPlayer();
else
return mediaPlayer;
}
}
I have a button with a text (Load video). This text is changed when the video is ready, and when the user clicks on it, it triggers the following activity.
The problem is that I get the following error in LogCat:
09-06 20:43:34.606: D/ChapterPlayer(31999): surfaceCreated called
09-06 20:43:34.684: V/ChapterPlayer(31999): startVideoPlayback

This is the code contained in the first Activity:
public void watchChapter(View view){
Log.i("Button", "Watch chapter button PRESSED");

I would appreciate some help or advice. Thanks!

I don't think you're saving the MediaPlayer in your application, you're just returning a new instance of it. Try changing it as so:
public static MediaPlayer getMediaPlayer() {
if(mediaPlayer == null) {
mediaPlayer = new MediaPlayer();
}
return mediaPlayer;
}
