该插件需要更新以更新最新版本的 Cordova。您可以从这里下载我的 Eclipse 测试项目，其中包含更新的插件代码和生成的 APK 。
请注意，由于 Android 4.x 中的这个错误，我不得不在 EmailComposer.java 中替换这一行：
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);
这可以解决纯文本电子邮件的问题，但不适用于 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。
更新插件的代码：

将 config.xml 中的行更改为：

然后对于 index.html 是这样的：

<script type="text/javascript" charset="utf-8" src="emailcomposer.js"></script>
