這裏是東西，可以幫助你。確保你以正確的方式拼寫你的圖像文件路徑。不要忘記「/」分隔符（嘗試獲取路徑的日誌）。另外，請確保該文件存在。

/** ATTACHING IMAGE TO EMAIL AND SENDING EMAIL */ 
     Button b1 = (Button)findViewById(R.id.finalsectionsubmit); 
     b1.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 

     Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
//  emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailSignature); 
     emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, toSenders); 
     emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subjectText); 
     emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, messageText+"\n\n"+emailSignature); 

     emailIntent.setType("image/jpeg"); 
     File bitmapFile = new File(Environment.getExternalStorageDirectory()+ 
      "/"+FOLDER_NAME+"/picture.jpg"); 
     myUri = Uri.fromFile(bitmapFile); 
     emailIntent.putExtra(Intent.EXTRA_STREAM, myUri); 


     startActivity(Intent.createChooser(emailIntent, "Send your email in:")); 
     eraseContent(); 
     sentMode = true; 
     } 
    });
