java - Playing Online Videos one by one -

i have xml file videoview:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"    android:background="@drawable/back"     android:orientation="vertical"      android:screenorientation="landscape">   <videoview             android:id="@+id/videoview_concept"             android:layout_width="match_parent"             android:layout_height="match_parent" /> </linearlayout> 

and java part is:

public class playvideos extends activity implements oncompletionlistener{     public integer index_val=0;     @override     public void oncompletion(mediaplayer mediaplayer) {         index_val++;         videoview videoview= (videoview)findviewbyid(r.id.videoview_concept);         checkdbconn();         videoview.setvideouri(uri.parse(prepare.txtlecturefilename[index_val]));         videoview.setmediacontroller(new mediacontroller(this));         videoview.requestfocus();         videoview.start();       }     public void playvideo(view view){             setcontentview(r.layout.playvid);             videoview videoview= (videoview)findviewbyid(r.id.videoview_concept);             log.i("video url",videourl_array[index_val]);             checkdbconn();             videoview.setvideouri(uri.parse(videourl_array[index_val]));             videoview.setmediacontroller(new mediacontroller(this));             videoview.requestfocus();             checkdbconn();             videoview.start();          } 

the above code button click event. works well. if 1 first video finished, should automatically play second video. want play videos in array continuously. how achieve this? please me out:)

public class mainactivity extends activity implements oncompletionlistener{      @override     public void oncompletion(mediaplayer mediaplayer) {          // play next video      } }
