为什么我的意图没有开始活动？

Question

我的代码是这样的:

Intent i = new Intent(Intent.ACTION_SENDTO);
i.putExtra(Intent.EXTRA_EMAIL,"example @example. Com");
i.putExtra(Intent.EXTRA_SUBJECT,"Grannylaunch Support Needed:" + System.currentTimeMillis());
startActivity(i);
Toast.makeText(getApplicationContext(),"Emailing Support....", Toast.LENGTH_LONG);

我的问题是意图不是开始活动.我做错了什么,我该如何解决？

我尝试过设置intent = Intent.ActionSend,但是没有用.

编辑 -

Intent i = new Intent(Intent.ACTION_SENDTO);
i.putExtra(Intent.EXTRA_EMAIL,"example@example.com");
i.putExtra(Intent.EXTRA_SUBJECT,"Grannylaunch Support Needed:" + System.currentTimeMillis());
i.putExtra(Intent.EXTRA_TEXT,"");
startActivity(i);
Toast.makeText(getApplicationContext(),"Emailing Support....", Toast.LENGTH_LONG); 

这也不起作用.

protected void sendEmail() {
      Log.i("Send email", "");

      String[] TO = {"amrood.admin@gmail.com"};
      String[] CC = {"mcmohd@gmail.com"};
      Intent emailIntent = new Intent(Intent.ACTION_SEND);
      emailIntent.setData(Uri.parse("mailto:"));
      emailIntent.setType("text/plain");


      emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
      emailIntent.putExtra(Intent.EXTRA_CC, CC);
      emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
      emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");

      try {
         startActivity(Intent.createChooser(emailIntent, "Send mail..."));
         finish();
         Log.i("Finished sending email...", "");
      } catch (android.content.ActivityNotFoundException ex) {
         Toast.makeText(MainActivity.this, 
         "There is no email client installed.", Toast.LENGTH_SHORT).show();
      }
