英文:
Send html emails
问题
以下是翻译好的内容：
这个主题有很多关于问题和答案，但似乎没有一个能够解决我的问题。我在Google中搜索了“在Android Java中发送HTML电子邮件”并按照所有链接进行了尝试，但都没有成功（来自stackoverflow和其他网站）。我想从我的Android应用和Gmail应用程序中发送HTML电子邮件。我使用以下代码来实现，但我总是收到纯文本电子邮件：
Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
emailIntent.setType("message/rfc822");
emailIntent.putExtra(Intent.EXTRA_SUBJECT, mysubject);
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
emailIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
StringBuilder sbContent = new StringBuilder();
sbContent.append("<p>Text <strong>with html</strong></p>");
emailIntent.putExtra(Intent.EXTRA_TEXT, HtmlCompat.fromHtml(sbContent.toString(), HtmlCompat.FROM_HTML_MODE_LEGACY));
startActivity(Intent.createChooser(emailIntent, ""));
我尝试过将类型更改为“text/plain”，将EXTRA_TEXT更改为EXTRA_HTML_TEXT，以及其他一些尝试，但都没有成功。是否有人有如何实现此功能的示例？

There are a lot of questions and answer about this topic but none of them seems to work. I have search in Google about "send html email Android Java" and followed all links without success (from stackoverflow and from other sites). I want to send an HTML email from my android app and Gmail app. I use the next code to do it but I always get a text email:
Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
emailIntent.setType("message/rfc822");
emailIntent.putExtra(Intent.EXTRA_SUBJECT, mysubject);
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
emailIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
StringBuilder sbContent = new StringBuilder();
sbContent.append("<p>Text <strong>with html</strong></p>");
emailIntent.putExtra(Intent.EXTRA_TEXT, HtmlCompat.fromHtml(sbContent.toString(), HtmlCompat.FROM_HTML_MODE_LEGACY));
startActivity(Intent.createChooser(emailIntent, ""));
I've tried changing type to "text/plain", EXTRA_TEXT with EXTRA_HTML_TEXT, and some other attemps, but without success. Does anyone have an example of how to do it?
