Question

我正在使用之前的Stack Overflow回复here

中的代码

它在android 2.2,2.3中完美运行

但它不适用于4.1及以上版本 - 任何人都可以帮我解决问题吗？

Answer 1

使用此代码段：

// mail function
    private void mail() {
        Intent i = new Intent(Intent.ACTION_SEND);
        i.setType("message/rfc822");
        i.putExtra(Intent.EXTRA_EMAIL,
                new String[] { "abc@xyz.in" });
        i.putExtra(Intent.EXTRA_SUBJECT, "ENQUERY");
        i.putExtra(Intent.EXTRA_TEXT, "");
        try {
            startActivity(Intent.createChooser(i, "Send mail..."));
        } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(ContactUsActivity.this,
                    "Email can't be sent due to device problem",
                    Toast.LENGTH_SHORT).show();
        }
    }

它对我有用！

您很可能收到错误，因为您没有将电子邮件作为异步任务发送。 ICS及以上版本不允许在主线程中进行交易！

在Android 4.1及更多内容中发送电子邮件
