    android ssl httpconnection
    i’m working on an application for android devices( 2.2). I’m trying to get an html page.The java code I use seems to work, so I can obtain the page I want, but sometimes the app crashes and i get the exception: “no peer certificate”. When this happens, if I wait one hour or I change network, it works normally. Does someone know how to solve this?

    java android connect httpconnection

The following snippet works just fine, but when I take it and place it into another class the urlConnect(); connects just fine. I’ve marked it below.public String downloadUrl(String strUrl) throws IOException{String data = “”;InputS

    eclipse-plugin httpconnection
    I was trying to create a Httpconnection inside the Object execute(ExecutionEvent event) method of a handler class for Eclipse plug-in project. The idea is when I select a context menu item, the plug-in will collect information from a web API creating a httpconnection. But looks like it fails to create the connection. I also added the required libraries as Reference libraries, but looks like the plugin can not load the library runtime. Here is the error message.!SESSION 2013-05-08 15:56:12.381 —
