Android Video View not support on v2.2

i had developed one application to live streaming video, but it does not support android version 2.2 ,2.3 or etc. only play video on android version 4.1 (Samsung Galaxy Grand).
I am using videoview in my project.
So can you tell me the exact reason.
My code is as follow:
mPath.setText("http://iptvshqip.dyndns.tv:8090");
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(MainActivity.this, "File URL/path is empty",
Toast.LENGTH_LONG).show();
}
else {
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;
}
}

Android started HTTP Live Stream(HLS) support from 3.0. Read the following link.
http://www.longtailvideo.com/blog/31646/the-pain-of-live-streaming-on-android/
They have explained with workaround.

As stated, the Android VideoView has existed since API level 1.
Except:
flags STATUS_BAR_HIDDEN and STATUS_BAR_VISIBLE - deprecated in API 14
the function setBackgroundDrawable(Drawable background) deprecated in API 16
the Public Methods - canPause(), canSeekBackward() and canSeekForward() added in API 5
resume() and suspend() added in API 8
onInitializeAccessibilityEvent (AccessibilityEvent event) and onInitializeAccessibilityNodeInfo (AccessibilityNodeInfo info) added in API 14
setOnInfoListener (MediaPlayer.OnInfoListener l) added in API 17
Do you use any of these? Your problem might be elsewhere anyway.
Please paste some code and describe with more details how is this not working.

Do you know why mediaplayer runonuithread doesn't work?

I am trying to run Android's MediaPlayer using runOnUiThread. I did not caught any exception with setDataSource. But after that, nothing happens with MediaPlayer. It should give callback as surface changed and onPrepared.
It seems MediaPlayer doesn't support this way.
If it is true, are there any workarounds ?
I need this kind of logic because I need to get info with network query which is blocked. I need to run onSuccess from that.
What is your suggestion for this? Thanks very much!
onResume()
{
getInfo(xxx);
}
void getInfo(url, new DataListener() {
#Override
public void onDataSuccess(xxx) {
playVideoOnSuccess(xxx);
}
}
public void playVideoOnSuccess(xxx)
{
myBaseActivity.runOnUiThread(new Runnable() {
#Override
public void run() {
try {
mPlayerListener = new VideoPlayerListener(null, content);
// create new mediaplayer
mVideoPlayer = VideoPlayer.getInstance();
mVideoPlayer.setVideoPlayerListener(mPlayerListener);
// setDataSource
mVideoPlayer.consumeContent(content);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

Here is a sample code that i used to play video hope this might help you in some way
public class VideoViewDemo extends Activity {
private static final String TAG = "VideoViewDemo";
private String current;
/**
* TODO: Set the path variable to a streaming video URL or a local media
* file path.
*/
private String path = "http://www.boisestatefootball.com/sites/default/files/videos/original/01%20-%20coach%20pete%20bio_4.mp4";
private VideoView mVideoView;
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.videoview);
mVideoView = (VideoView) findViewById(R.id.surface_view);
runOnUiThread(new Runnable() {
public void run() {
playVideo();
}
});
}
private void playVideo() {
try {
// final String path = path;
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.setMediaController(new MediaController(this));
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;

This work for me

Hi got it solved by below methods on setOnClickListener event get the current postion of videow view and change the video source to HD and use SeekTo method with current position and then start HD video so that HD video cans tart from current postion of previous SD video.

How to convert Youtube URL to RTSP URL?

In my project I want to dowload a Youtube URL and play it in media player but as far I have searched I got an idea that Youtube URLs can be played only if they are converted into a RTSP file. I don't have any idea of how to do that. It would be very helpful if you send me a sample project.
