Highlights of Android problems: transport endpoint is not connected

At that time, my simulator was accessible to the Internet,

And my HTTP ConnectionProgramIt's verified,

So I have not solved the problem for a long time.

The problem was discovered by accident,

I used a proxy to access the Internet, and a proxy was set up on the simulator,

However, proxy is also required for HTTP connection in the program,

Just like this:

// Proxy = new proxy (proxy. type. HTTP, new inetsocketaddress ("12.213.3.33", 80); Url url = new URL (strurl); httpurlconnection httpconnection = (httpurlconnection) URL. openconnection (proxy );
