解决方案

下面是一些可以帮助你。请确保您以适当的方式拼写你的映像文件的路径。不要忘了/分隔符（试图得到一个日志的路径）。此外，还要确保该文件存在。

  / **附加图像到电子邮件和发送电子邮件* /
        按钮B1 =（按钮）findViewById（R.id.finalsectionsubmit）;
        b1.setOnClickListener（新View.OnClickListener（）{

      @覆盖
      公共无效的onClick（视图v）{

        意图emailIntent =新的意图（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）;

      startActivity(picMessageIntent);
    }

解决方案

Here is something that can help you. Make sure you spelled your image file path in a proper manner. Don't forget the "/" separator (try to get a log of your path). Also, be sure that the file exists.

/** 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;
      }
    });
