我正在使用 phonegap Android 插件：EmailComposerwithAttachments https://github.com/phonegap/phonegap-plugins/tree/master/Android/EmailComposerWithAttachments执行 startActivitywithResult 函数时出现以下错误。我正在使用带有 Cordova 2.5.0 的 Android 4.2

java.lang.ClassCastException: android.text.SpannableStringBuilder 不能转换为 java.util.ArrayList

// setting attachments
    try {
        JSONArray attachments = parameters.getJSONArray("attachments");
        if (attachments != null && attachments.length() > 0) {
            ArrayList<Uri> uris = new ArrayList<Uri>();
            //convert from paths to Android friendly Parcelable Uri's
            for (int i=0; i<attachments.length(); i++) {
                try {
                    File file = new File(attachments.getString(i));
                    if (file.exists()) {
                        Uri uri = Uri.fromFile(file);
                        uris.add(uri);
                    }
                } catch (Exception e) {
                    LOG.e("EmailComposer", "Error adding an attachment: " + e.toString());
                }
            }
            if (uris.size() > 0) {
                emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
            }
        }
    } catch (Exception e) {
        LOG.e("EmailComposer", "Error handling attachments param: " + e.toString());
    }

    this.cordova.startActivityForResult(this, emailIntent, 0);

在 Android 4.x 中解决了这个错误

您可以通过替换 EmailComposer.java 中的这一行来解决纯文本电子邮件的问题：

emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, body);

和

ArrayList<String> extra_text = new ArrayList<String>();
extra_text.add(body);
emailIntent.putStringArrayListExtra(android.content.Intent.EXTRA_TEXT, extra_text);

但这不适用于 HTML 电子邮件，因为 Spanned（由 Html.fromHtml 返回）不是 Charsequence 的子类。当我尝试将 Html.fromHtml() 的结果转换为字符串时，标签显示为文本的一部分:-(

同样，当我尝试此操作时，使用 Gmail 应用程序时会出现纯文本电子邮件的正文，但它没有出现在股票电子邮件应用程序中 - 正文始终为空白。

只需尝试不同的方法：

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" + email));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, body);
//emailIntent.putExtra(Intent.EXTRA_HTML_TEXT, body); //If you are using HTML in your body text

startActivity(Intent.createChooser(emailIntent, "Chooser Title"));

取自这里：发送电子邮件意图
