问题
This is an example of a video I want to show in my app.
http://www.dailymotion.com/embed/video/x1ade3x
1.In Manifest I use permission like this
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
2.In Layout I use VideoView like this
<VideoView
android:id="@+id/vdo_ContentVideo"
android:layout_width="match_parent"
android:layout_height="360dp"/>
3.In onCreate I use this code
vdo_ContentVideo = (VideoView)findViewById(R.id.vdo_ContentVideo);
if(vdo_ContentVideo != null){
String path1="http://www.dailymotion.com/embed/video/x1ade3x";
Uri uri=Uri.parse(path1);
MediaController mc = new MediaController(this);
mc.setAnchorView(vdo_ContentVideo);
mc.setMediaPlayer(vdo_ContentVideo);
vdo_ContentVideo.setMediaController(mc);
vdo_ContentVideo.setVideoURI(uri);
vdo_ContentVideo.start();
}
4.when I run my app it's show "Can't play this video" Why?
5.How can i display video from URL?
EDIT
I can solve my problem. It's work with above url ("http://www.dailymotion.com/embed/video/x1ade3x")
I try this
1.In Layout I use WebView like this
<WebView
android:id="@+id/webView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
2.In MainActivity
public class MainActivityextends Activity{
String url = "http://www.dailymotion.com/embed/video/x1ade3x";
WebView mWebView = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
weatherInfo = getIntent().getExtras().getParcelable("weatherdata");
setContentView(R.layout.activity_main2);
initwebView(rootView);
}
private void initwebView(View root) {
mWebView = (WebView) root.findViewById(R.id.webView);
/** unfortunately, we have to check sdk version ***/
if (Build.VERSION.SDK_INT < 8) {
//mWebView.getSettings().setPluginsEnabled(true);
} else {
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
}
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.loadUrl(url);
}
}
It's work very well and work with youtube embed
but not work with url is contain file type like this "http://www.w3schools.com/html/mov_bbb.mp4"
Thank you every people. My problem was solve. ;)

First convert your video file as .MP4 or .3GP.Here is the code which work for me to display video from Url.
public class VideoViewDemo extends Activity {
private static final String TAG = "VideoViewDemo";
private VideoView mVideoView;
private EditText mPath;
private ImageButton mPlay;
private ImageButton mPause;
private ImageButton mReset;
private ImageButton mStop;
private String current;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
mVideoView = (VideoView) findViewById(R.id.surface_view);
mPath = (EditText) findViewById(R.id.path);
mPath.setText("http://daily3gp.com/vids/747.3gp");
mPlay = (ImageButton) findViewById(R.id.play);
mPause = (ImageButton) findViewById(R.id.pause);
mReset = (ImageButton) findViewById(R.id.reset);
mStop = (ImageButton) findViewById(R.id.stop);
mPlay.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
playVideo();
}
});
mPause.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mVideoView != null) {
mVideoView.pause();
}
}
});
mReset.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mVideoView != null) {
mVideoView.seekTo(0);
}
}
});
mStop.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mVideoView != null) {
current = null;
mVideoView.stopPlayback();
}
}
});
runOnUiThread(new Runnable() {
public void run() {
playVideo();
}
});
}
private void playVideo() {
try {
final String path = mPath.getText().toString();
Log.v(TAG, "path: " + path);
if (path == null || path.length() == 0) {
Toast.makeText(VideoViewDemo.this, "File URL/path is empty",
Toast.LENGTH_LONG).show();
} else {
// If the path has not changed, just start the media player
if (path.equals(current) && mVideoView != null) {
mVideoView.start();
mVideoView.requestFocus();
return;
}
current = path;
mVideoView.setVideoPath(getDataSource(path));
mVideoView.start();
mVideoView.requestFocus();
}
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
if (mVideoView != null) {
mVideoView.stopPlayback();
}
}
}
private String getDataSource(String path) throws IOException {
if (!URLUtil.isNetworkUrl(path)) {
return path;
} else {
URL url = new URL(path);
URLConnection cn = url.openConnection();
cn.connect();
InputStream stream = cn.getInputStream();
if (stream == null)
throw new RuntimeException("stream is null");
File temp = File.createTempFile("mediaplayertmp", "dat");
temp.deleteOnExit();
String tempPath = temp.getAbsolutePath();
FileOutputStream out = new FileOutputStream(temp);
byte buf[] = new byte[128];
do {
int numread = stream.read(buf);
if (numread <= 0)
break;
out.write(buf, 0, numread);
} while (true);
try {
stream.close();
} catch (IOException ex) {
Log.e(TAG, "error: " + ex.getMessage(), ex);
}
return tempPath;
}
}
}
回答2:
are you sure you want to call it in onCreate? Activity is not yet visible. Try something like this:
VideoView videoView;
videoView.post(new Runnable() {
@Override
public void run() {
MediaController mc = new MediaController(this);
mc.setAnchorView(vdo_ContentVideo);
mc.setMediaPlayer(vdo_ContentVideo);
vdo_ContentVideo.setMediaController(mc);
vdo_ContentVideo.setVideoURI(uri);
vdo_ContentVideo.start();
}
});

Hi First you need to convert your video file as .MP4 or .3GP mobile resolution supported. after that follow below code
VideoView video_player_view;
DisplayMetrics dm;
MediaController media_Controller;
String path1="http://www.dailymotion.com/embed/video/x1ade3x";
Uri uri=Uri.parse(path1);
video_player_view = (VideoView) findViewById(R.id.video);
dm = new DisplayMetrics();
this.getWindowManager().getDefaultDisplay().getMetrics(dm);
int height = dm.heightPixels;
int width = dm.widthPixels;
video_player_view.setMinimumWidth(width);
video_player_view.setMinimumHeight(height);
video_player_view
.setVideoPath(uri); //here you put your url
video_player_view.start();
