我正在使用 EmailComposer 开发一个 Android PhoneGap 项目。除附件部分外，一切正常。我在 Eclipse 中的 LogCat 中没有看到任何错误。一直在网上寻找解决方案，以找出文件未附加到电子邮件的原因。我的 2.2.2 和 4.0.4 android 设备工作正常，但再次没有附加电子邮件。我正在使用cordova.2.9.0.jar。有人可以阐明一下吗？
这是触发 EmailComposerWithAttachment 插件的 .js 电子邮件编写器。
function composeText(){
window.plugins.emailComposer.showEmailComposerWithCallback(
null,
"Look at this photo","Take a look at <b>this<b/>:",
["example@email.com", "johndoe@email.org"],
[],
[],
true,
["file:///mnt/sdcard/Android/data/com.thing.thing/cache/thing/file.wav"]
);
}
这是 EmailComposer.java 文件

}
@Override

// todo handle callback
super.onActivityResult(requestCode, resultCode, intent);
LOG.e("EmailComposer", "ResultCode: " + resultCode);

}
最后但并非最不重要的是 EmailComposer.js 文件
// window.plugins.emailComposer
function EmailComposer() {
this.resultCallback = null; // Function
}
EmailComposer.ComposeResultType = {
Cancelled:0,
Saved:1,
Sent:2,
Failed:3,
NotSent:4
}
// showEmailComposer : all args optional
EmailComposer.prototype.showEmailComposer = function(subject,body,toRecipients,ccRecipients,bccRecipients,bIsHTML,attachments) {
console.log("****************************AVVIATO");
var args = {};
if(toRecipients)
args.toRecipients = toRecipients;
if(ccRecipients)
args.ccRecipients = ccRecipients;
if(bccRecipients)
args.bccRecipients = bccRecipients;
if(subject)
args.subject = subject;
if(body)
args.body = body;
if(bIsHTML)
args.bIsHTML = bIsHTML;
if(attachments)
args.attachments = attachments;
cordova.exec(null, null, "EmailComposer", "showEmailComposer", [args]);
}
EmailComposer.prototype.showEmailComposerWithCallback = function(callback, subject, body, toRecipients, ccRecipients, bccRecipients, isHTML, attachments) {
this.resultCallback = callback;
this.showEmailComposer.apply(this,[subject,body,toRecipients,ccRecipients,bccRecipients,isHTML,attachments]);
}
EmailComposer.prototype._didFinishWithResult = function(res) {
this.resultCallback(res);
}
cordova.addConstructor(function() {
console.log("****************************");
if(!window.plugins)
{
window.plugins = {};
}
// shim to work in 1.5 and 1.6
if (!window.Cordova) {
window.Cordova = cordova;
};
window.plugins.emailComposer = new EmailComposer();
});
请注意，我去过原始的 EmailComposer github repo bit 并没有在那里找到任何答案。Stackoverflow 提供了一些见解，但并没有专门针对附件。任何帮助是极大的赞赏。
