这里是东西，可以帮助你。确保你以正确的方式拼写你的图像文件路径。不要忘记“/”分隔符（尝试获取路径的日志）。另外，请确保该文件存在。

/** 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; 
     } 
    }); 

在这个
