推荐答案
window.plugins.WebIntent.startActivity('WebIntent', success, fail);
应该是这样的地图对象：
Should be a map object like this:
window.plugins.WebIntent.startActivity({url: 'url here', type: 'type', extras: {}}, success, fail);
编辑
使用此功能呼叫意图
Edit
Using this function to call the intent
function sendEmail(to, subject, body) {
var extras = {};
extras[WebIntent.EXTRA_SUBJECT] = subject;
extras[WebIntent.EXTRA_TEXT] = body;
window.plugins.webintent.startActivity({
url: to,
action: WebIntent.ACTION_SEND,
type: 'text/plain',
extras: extras
},
function() {
alert("mail sent");
},
function() {
alert('Failed to send email via Android Intent');
}
);
}
它会打开包含所有已发送参数的邮件发送对话框。
It opens up the mail send dialog with all the sent parameter.
