public class MyPhoneGallery extends Activity  {

  /** Called when the activity is first created. */
  private Cursor imagecursor, actualimagecursor;
  private int image_column_index, actual_image_column_index;
  GridView imagegrid;
  private int count;
  @Override
  public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gallery);
        init_phone_image_grid();
  }
  private void init_phone_image_grid() {
        String[] img = { MediaStore.Images.Thumbnails._ID };
        imagecursor = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null,null, MediaStore.Images.Thumbnails.IMAGE_ID + "");
        image_column_index = imagecursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
        count = imagecursor.getCount(); 
        imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
        imagegrid.setAdapter(new ImageAdapter(getApplicationContext()));
        imagegrid.setOnItemClickListener(new OnItemClickListener() {
          public void onItemClick(AdapterView parent, View v,int position, long id) {

              System.gc();
              String[] proj = { MediaStore.Images.Media.DATA };
              actualimagecursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,null, null, null);
              actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
              actualimagecursor.moveToPosition(position);
              String i = actualimagecursor.getString(actual_image_column_index);
              System.gc();
              Intent intent = new Intent(getApplicationContext(), ViewImage.class);
              intent.putExtra("filename", i);
              startActivity(intent);

           }
      });
  }

  public class ImageAdapter extends BaseAdapter {
        private Context mContext;
        public ImageAdapter(Context c) {
              mContext = c;
         }
        public int mygetItemId(int position) {
            // TODO Auto-generated method stub
            return 0;
        }
        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();
              ImageView i = new ImageView(mContext.getApplicationContext());
              if (convertView == null) {
                    imagecursor.moveToPosition(position);
                    int id = imagecursor.getInt(image_column_index);
                    i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id));
                    i.setScaleType(ImageView.ScaleType.CENTER_CROP);
                    i.setLayoutParams(new GridView.LayoutParams(125, 125));
              }
              else {
                    i = (ImageView) convertView;
              }
              return i;
        }
  }
