问题
i have problem to reproduce a video with videoView.setVideoPath();
in fact video doesn't reproduce..i don't know why. Video's path is correct.
This is my code:
public class MainActivity extends AppCompatActivity {
private VideoView videoView;
private int position = 0;
private MediaController mediaController;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videoView = (VideoView) findViewById(R.id.videoView);
// Set the media controller buttons
if (mediaController == null) {
mediaController = new MediaController(MainActivity.this);
// Set the videoView that acts as the anchor for the MediaController.
mediaController.setAnchorView(videoView);
// Set MediaController for VideoView
videoView.setMediaController(mediaController);
}
try {
// ID of video file.
String videoUrl="https://www.youtube.com/watch?v=JHdmkP-nfsA";
videoView.setVideoPath(videoUrl);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoView.requestFocus();
// When the video file ready for playback.
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mediaPlayer) {
videoView.seekTo(position);
if (position == 0) {
videoView.start();
}
// When video Screen change size.
mediaPlayer.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
// Re-Set the videoView that acts as the anchor for the MediaController
mediaController.setAnchorView(videoView);
}
});
}
});
}
}
Who can help me?

You can not play a YouTube video directly to the VideoView or ExoPlayer, for that, first you have to download the video then set the locale path of that video to the method VideoView.setVideoPath("path")
If you want to play only YouTube videos then use YouTube Android Player API, and if you only want to play other remote videos (.mp4, .ogg, .3gp etc.) then use the method VideoView.setVideoURI("uri").
Example-
String videoUrl = "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4";
try {
// Start the MediaController
MediaController mediacontroller = new MediaController(this);
mediacontroller.setAnchorView(videoview);
// Get the URL from String videoUrl
Uri video = Uri.parse(videoUrl);
videoview.setMediaController(mediacontroller);
videoview.setVideoURI(video);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoview.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
videoview.start();
}
});

VideoView.setVideoPath requires a local path on the device. You should try setVideoURI instead if you want to play a remote MP4 or something else. VideoView Documentation
If you want to embed YouTube videos in your app, consider using the YouTube Android Player API or using something like a WebView

I had same issue but it was because of corporate proxy server. I used same app over my mobile internet and it started working. Hope it save someone's time
回答4:
I recommend using ExoPlayer instead of VideoView:
app gradle:
implementation 'com.google.android.exoplayer:exoplayer:2.10.8'
layout xml:
<com.google.android.exoplayer2.ui.PlayerView
android:id="@+id/video_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true" />
java code:
PlayerView videoView = findViewById(R.id.video_view);
SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(this);
videoView.setPlayer(player);
// Produces DataSource instances through which media data is loaded.
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "yourApplicationName"));
// This is the MediaSource representing the media to be played.
MediaSource videoSource = new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(fileEntity.getPath()));
// Prepare the player with the source.
player.prepare(videoSource);
player.setPlayWhenReady(true);
回答5:
You are using VideoView which
Displays a video file. The VideoView class can load images from various sources (such as resources or content providers).
You might want to try setVideoURI
Or : ExoPlayer if min SDK > 16
Or use SurfaceView :
SurfaceView surfaceView = (SurfaceView)findViewById(R.id.surfaceView);
SurfaceHolder surfaceHolder = surfaceView.getHolder();
surfaceHolder.addCallback(new SurfaceHolder.Callback() {
@Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
mediaPlayer.setDataSource(STREAM_URL);
mediaPlayer.setDisplay(surfaceHolder);
mediaPlayer.start();
}
