Android: app forces close when trying to play video from URI
===

I have written this code to try and stream a video to my Android device. Upon clicking an icon, a popup window should appear with the VideoView inside it. However, whenever I click the image to trigger the popup, it forces closes. The URL I'm using is apparently able to be streamed to a device, I got it from another SO question. This is the code in my class.

		video.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				final Dialog dialog = new Dialog(context);
				dialog.setContentView(R.layout.pop_up);
				dialog.setTitle("Safe Cracker Overview");

				VideoView vv = (VideoView)findViewById(R.id.vv01);
				MediaController mc = new MediaController(context);
				mc.setAnchorView(vv);
				mc.setMediaPlayer(vv);
				vv.setMediaController(mc);
				vv.setVideoURI(Uri.parse("http://hermes.sprc.samsung.pl/widget/tmp/testh.3gp"));
				vv.requestFocus();
				vv.start();
				Button ok = (Button)findViewById(R.id.but01);
				
				ok.setOnClickListener(new View.OnClickListener() {
					
					@Override
					public void onClick(View v) {
						// TODO Auto-generated method stub
						dialog.dismiss();
					}
				});
				
				dialog.show();
			}
		});


And the XML for the popup layout:

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/layout1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
    
        <VideoView
            android:id="@+id/vv01"
            android:layout_width="fill_parent"
            android:layout_height="200dp"
            android:layout_marginTop="20dp"
            android:background="#0000" >
        </VideoView>
    
        <Button
            android:id="@+id/but01"
            android:layout_width="150dp"
            android:layout_height="40dp"
            android:layout_gravity="center"
            android:layout_marginTop="10dp"
            android:background="@drawable/green_button"
            android:text="@string/back"
            android:textColor="@color/white"
            android:textSize="16dp" >
        </Button>
    
    </LinearLayout>

Can anyone see the issue here? Thanks
