              private int video_column_index;
              ListView videolist;
              int count;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            gallybutton  = (Button) findViewById(R.id.gally);
            gallybutton.setOnClickListener((OnClickListener) this);

        }
            public void onClick(View v) {


          init_phone_video_grid();
    }
      public void init_phone_video_grid() {
              System.gc();
              String[] proj = { MediaStore.Video.Media._ID,
    MediaStore.Video.Media.DATA,
    MediaStore.Video.Media.DISPLAY_NAME,
    MediaStore.Video.Media.SIZE };
              videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,   proj, null, null, null);
              count = videocursor.getCount();
              videolist = (ListView) findViewById(R.id.PhoneVideoList);
              videolist.setAdapter(new VideoAdapter(getApplicationContext()));
              videolist.setOnItemClickListener(videogridlistener);
        }

        public OnItemClickListener videogridlistener = new OnItemClickListener() {
              public void onItemClick(AdapterView<?> parent, View v, int position,
    long id) {
                    System.gc();
                    video_column_index = videocursor
    .getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
                    videocursor.moveToPosition(position);
                    String filename = videocursor.getString(video_column_index);

                    intent.putExtra("videofilename", filename);
                    startActivity(intent);
              }
        };

        public class VideoAdapter extends BaseAdapter {
              private Context vContext;

              public VideoAdapter(Context c) {
                    vContext = c;
              }

              public int getCount() {
                    return count;
              }

              public Object getItem(int position) {
                    return position;
              }

              public long getItemId(int position) {
                    return position;
              }

              public View getView(int position, View convertView, ViewGroup parent) {
                    System.gc();
                    TextView tv = new TextView(vContext.getApplicationContext());
                    String id = null;
                    if (convertView == null) {
                          video_column_index = videocursor
    .getColumnIndexOrThrow(MediaStore.Video.Media.DISPLAY_NAME);
                          videocursor.moveToPosition(position);
