Question

我正在尝试在我正在为我的工作（社交住房）制作的应用中实施phonegap插件WebIntent。我希望该应用能够将带有附件的电子邮件（维修图片等）发送到我们的办公室，以便我们能够准确了解我们需要维修的内容并提供更好的服务。

我已设法启动相机并可拍照，然后成功将应用程序指向包含WebIntent插件的功能。以下是我的剧本：

 function camera()
 {
 navigator.camera.getPicture(sendEmail, onFail, { quality: 20,
 destinationType: Camera.DestinationType.FILE_URI });

 function sendEmail(to, subject, body) {
 var extras = {};
 extras[WebIntent.EXTRA_SUBJECT] = "Test";
 extras[WebIntent.EXTRA_TEXT] = "Test";
 window.plugins.webintent.startActivity({
 url: "johnsmith@gmail.com",
 action: WebIntent.ACTION_SEND,
 type: 'image/jpeg',
 extras: extras
 },
 function() {
 alert("mail sent");
 },
 function() {
 alert('Failed to send email');
 }
 );
 }

 function onFail(message) {
 alert('Failed because: ' + message);
 }

 }

正如您所看到的，目前我并没有尝试将imageURI传递给WebIntent。我只想先让插件使用一些简单的文本。但是，每当我运行此功能时，插件都会返回“无法发送邮件”警报，甚至无需打开我的邮件应用程序。我出错的任何想法？

我的Logcat看起来像这样：

我是否设置错误？我已将WebIntent.Java添加到src / com / borismus，我已将webintent.js添加到assets / www，我已将插件添加到我的config.xml中，并且我已在我的html文件中引用了js。有什么我想念的吗？我正在使用Cordova 2.2.0。

是否有更好的方法将图像传递给邮件应用程序？我知道适用于iOS的EmailComposer，但我最初正在寻找Android解决方案。任何“共享”插件都可以这样做吗？

非常感谢任何帮助。

Answer 1

因此，在google群组phonegap页面上发布此问题后，我找到了解决方案。在我的情况下，我把WebIntent.java放在错误的填充程序中。

我将WebIntent.java放在src / com / borismus中。

但它应该在src / com / borismus / webintent中。

对于任何感兴趣的人，以下代码启动相机应用程序，然后成功将该图片附加到使用WebIntent插件预填充字段的电子邮件中：

    function camera()
    {
        navigator.camera.getPicture(sendEmail, onFail, { quality: 20, 
            destinationType: Camera.DestinationType.FILE_URI }); 

        function sendEmail(imageURI) { 
            var extras = {};
            extras[WebIntent.EXTRA_SUBJECT] = "Please type your name and address here.";
            extras[WebIntent.EXTRA_TEXT] = "Please type your query here.";
            extras[WebIntent.EXTRA_STREAM] = imageURI;
            window.plugins.webintent.startActivity({
                url: "johnsmith@gmail.com",
                action: WebIntent.ACTION_SEND,
                type: 'image/jpeg', 
                extras: extras 
              }, 
              function() {
                  alert("Mail sent");
              }, 
              function() {
                alert('Failed to send email');
              }
            ); 
        }

        function onFail(message) {
            alert('Failed because: ' + message);
        }

    }

希望这可以帮助别人。

感谢。

参考您的Logcat，[ClassNotFoundException: com.borismus.webintent.WebIntent] 我认为你在config.xml ..

中定义插件时遇到问题

有关详情，请查看https://github.com/InQBarna/WebIntent/blob/master/plugin.xml

如何在Phonegap 2.2.0中正确实现WebIntent插件？
