I want to play video in VideoView. When I try to do that I got the following error:

Here is my source code:

package com.video.listitem; import android.app.Activity; import android.content.pm.ActivityInfo; import android.media.MediaPlayer; import android.Uri; import android.os.Bundle; import android.view.Window; import android.view.WindowManager; import android.widget.MediaController; import android.widget.VideoView; public class PlayVideo extends Activity { VideoView mVideoView; MediaController mc; String videourl; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.videoplay); try { mVideoView = (VideoView) findViewById(R.id.videoview); String videourl = "rtsp://v7.cache4.c.youtube/CiILENy73wIaGQl25yDUbxNXTRMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp"; mc = new MediaController(this); mVideoView.setMediaController(mc); mVideoView.requestFocus(); mVideoView.setVideoURI(Uri.parse(videourl)); mc.show(); mVideoView.start(); } catch (Exception e) { //TODO: handle exception } } }

Here is my XML File:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="schemas.android/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scrollbars="none" android:gravity="center"> <VideoView android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/videoview" /> </LinearLayout>

解决方案
