我在我的应用中使用电子邮件编辑器。我从Android下载插件。 https://github.com/phonegap/phonegap-plugins/tree/master/Android/EmailComposerWithAttachments。 之后我会做同样的事情，写在自述文件中。
在我的src代码中添加java文件。
在我的js文件夹中添加js文件。
在config.xml文件中添加插件。
<plugin name="EmailComposer" value="com.example.procat"/>
但我仍然收到此错误。

答案 0 :(得分：2)
插件需要更新更新版本的Cordova。您可以下载包含更新的插件代码和生成的APK from here的Eclipse测试项目。
请注意，由于Android 4.x中的this bug，我必须在EmailComposer.java中替换此行：
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, body);
与
ArrayList<String> extra_text = new ArrayList<String>();
extra_text.add(body);
emailIntent.putStringArrayListExtra(android.content.Intent.EXTRA_TEXT, extra_text);
这解决了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，标记显示为文本的一部分： - （
此外，当我尝试此操作时，使用Gmail应用程序时会显示纯文本电子邮件，但它没有显示在库存中。电子邮件应用程序 - 正文始终为空白。
更新插件的代码：
