Android画廊显示错误

可能重复：
  Android: out of memory exception in Gallery

我正在尝试在网格视图中显示我的设备库。然后在从图库网格视图中选择特定图像时，我将该图像上传到服务器上。 上传图片没有问题。但是显示SD卡图像存在问题。 我的代码如下所示。

显示图库.. 

private void displayGallery() {

  Uri uri = MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI; // Where images are stored
  displaySdCard();
  String[] projection = {
    MediaStore.Images.ImageColumns._ID,  
    MediaStore.Images.ImageColumns.DATA, // The columns we want
    MediaStore.Images.Thumbnails.IMAGE_ID,  
    MediaStore.Images.Thumbnails.KIND };
  String selection = MediaStore.Images.Thumbnails.KIND + "="  + // Select only mini's
  MediaStore.Images.Thumbnails.MINI_KIND;
  mCursor = this.managedQuery(uri, projection, selection, null, null); 
  if (mCursor != null) { 
   mCursor.moveToFirst();
   int size = mCursor.getCount();
   Uri[] imgUri = new Uri[size];
   for(int k = 0; k < size; k++) {
    mCursor.moveToPosition(k);
       int id = mCursor.getInt(mCursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns._ID));
       Uri img_uri = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+id);
       imgUri[k] = img_uri;
   }


   GalleryImageAdapter galleryImageAdapter = new GalleryImageAdapter(this, imgUri); //(this, mCursor, size);
   gotoPage(pageGallery);
   grid_main.setAdapter(galleryImageAdapter);


  } else 
   showToast(this, "Gallery is empty.");
 }

适配器.. 

public class GalleryImageAdapter extends BaseAdapter{

 Context mContext;

 public static final int ACTIVITY_CREATE = 10;

 int i = 0;

 private int mImg_uri;

 private Cursor mCursor;


 public GalleryImageAdapter(Context Cursor cursor, int img_uri){
  mContext = c;
  mCursor = cursor;
  mImg_uri = img_uri

 }
 @Override
 public int getCount() {
  // TODO Auto-generated method stub
  return mUri.length;
 }

 public View getView(int position, View convertView, ViewGroup parent) {
  // TODO Auto-generated method stub
  View v;
  if(convertView==null){
   LayoutInflater li = (LayoutInflater)mContext.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
   v = li.inflate(R.layout.album_img, null);

   ImageView iv = (ImageView)v.findViewById(R.id.icon_image);

   try {
    mCursor.moveToPosition(position);
       int id = mCursor.getInt(mCursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns._ID));
       Uri img_uri = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+id);
       iv.setImageURI(img_uri );

   }
   catch(Exception ex) {
    ex.printStackTrace();
   }


  }
  else
  {
   v = convertView;
  }
  return v;
 }
 @Override
 public Object getItem(int position) {
  // TODO Auto-generated method stub
  return null;
 }
 @Override
 public long getItemId(int position) {
  // TODO Auto-generated method stub
  return 0;
 }
}

首次展示画廊。但从第2次开始，它给出了以下错误......
