问题 Im trying to improve the Java Html Document a little but i'm running into problems with the HttpUrlConntion . One thing is that some servers block a request if the user agent is a Java VM.

问题 I'm relatively new to android development. I'm developing an android application where i'm sending request to web server and parsing json objects. Frequently i'm getting java.net.SocketTimeoutException: Connection timed out exception while communicating with the server. Some times it will work perfectly without any problem.

问题 First of all I have two things that need your attention: 1) I tried this code on phones with api level lower than 11 and phones that are pretty high, like 4.3 or 4.4.
