		      super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 
		   
		      switch(requestCode) { 
		      case SELECT_PHOTO:
		          if(resultCode == RESULT_OK){  
		              Uri selectedImage = imageReturnedIntent.getData();
		              
		              //Uri uri=Uri.parse("file:///android_asset/myfile.pdf"); 
		              InputStream imageStream = null;
					try {
						//picturesone.setText(selectedImage.getPath());
						 imageStream = getContentResolver().openInputStream(selectedImage);
			        	    Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
							imageView.setImageBitmap(yourSelectedImage);
							
						File file = new File(imageReturnedIntent.getDataString()); 
			        	FileDataSource datasource1 = new FileDataSource(file); 
			        	DataHandler handler1 = new DataHandler(datasource1);

                                            autruche = new MimeBodyPart(); 
			        	
			        	    autruche.setDataHandler(handler1); 
			        	    autruche.setFileName(imageReturnedIntent.getDataString());
