我正在创建一个应用，它会在打开时自动向我的Gmail地址发送电子邮件（无需从设备（即Gmail）打开任何其他默认电子邮件发件人应用）。
我已经关注this link来创建此应用程序。
当设备连接到4G数据包时，它可以正常工作。但是当我将设备连接到WiFi时，每次它都会function doSomething() {
document.getElementById('test').innerHTML = parseInt(Math.random()*10);
}
function doSomethingElse() {
document.getElementById('test2').innerHTML = parseInt(Math.random() * 10);
}
function normal(x) {
if (x == true) {
doSomething();
} else {
doSomethingElse();
}
}
function inverted(x) {
if (x != true) {
doSomethingElse();
} else {
doSomething();
}
}
function callFunc(func, repetitions) {
var p;
for (var i = 0; i < repetitions; i++) {
p = Math.random() > .99;
func(p);
}
}
var reps = 1000000;
console.time('normal');
callFunc(normal, reps);
console.timeEnd('normal');
console.time('inverted');
callFunc(inverted, reps);
console.timeEnd('inverted');
。完整的错误日志是：
connection timed out供参考，我的代码如下：

那么我在这里失踪了什么？我的WiFi网络有问题吗？但互联网非常适合下载，浏览等其他内容。此外，我已经在同一个WiFi上发布了这个问题，而这个WiFi无法发送邮件。
谢谢。
