从SD卡读取图像时出现内存不足错误

我正在用ImageView开发一个简单的应用程序，当单击ImageView时应用程序应打开设备图库。实现这一我使用以下代码从SD卡读取图像时出现内存不足错误

Intent imageIntent=new Intent(Intent.ACTION_PICK); 
    imageIntent.setType("image/*"); 
    startActivityForResult(imageIntent,5);

而ActivityResult

super.onActivityResult(requestCode, resultCode, data); 
if(requestCode == 5) 
    { 
     Cursor cursor; 
     Uri uri=data.getData();  
     if(uri!=null) 
     { 
      cursor=getContentResolver().query(uri, new String[]{ android.provider.MediaStore.Images.ImageColumns.DATA }, 
        null, null, null); 
      cursor.moveToFirst(); 
      String imageID=cursor.getString(0); 
      personImage.setImageURI(uri); 
      Log.i("ImageId", ""+imageID); 
      cursor.close(); 
     } 
    }

所选图像被显示在ImageView的。现在的问题是，当我正在做第二次我得到以下例外。
