setting the proxy?

Question

I am making a broswer type app i want to set the proxy only for this browser

I tried to modify global proxy by using this code but it does not work

System.getProperties().put("http.proxyHost", "someProxyURL");
System.getProperties().put("http.proxyPort", "someProxyPort");
System.getProperties().put("http.proxyUser", "someUserName");
System.getProperties().put("http.proxyPassword", "somePassword");
System.getProperties().put("http.proxySet", "true");

So I looked at proxySelector class and I really don't understand how to set the proxy for my brower

I know there is a hidden class in ProxySelector in com.android.settings/.ProxySelector

But I have to manually entered the proxy.

Is there any way so that i can configure proxy only for mybrowser(Just a Webview) ??

Please Help. Thanks in Advance!!!

@Robert Thanks for your response I have found a solution which open a hidden activity com.android.settings.ProxySelector. Now I can set The proxy. But this activity does not have username/password field Can you guide me how can i set usename/password field so that i can open a webpage in webview. Now webview say forbidden because username/password is not set? — Sunny, Apr 11 '12 at 17:25
@Robert I looked at your link also but it always giving null on network Object. — Sunny, Apr 11 '12 at 17:47
Worth noting here that http.proxySet is an urban myth. Setting it has no effect. — user207421, Apr 11 '12 at 18:19

System.getProperties().put("http.proxyUser", "someUserName");
System.getProperties().put("http.proxyPassword", "somePassword");

These dont' work in the JDK, only in the Apache HTTP client.

System.getProperties().put("http.proxySet", "true");

This is an urban myth. It appears in some early Java books but has never done anything in the JDK. It is a relic of the defunct HotJavaBean browser c. 1998.

You should use it like

Authenticator.setDefault(
   new Authenticator() {
      public PasswordAuthentication getPasswordAuthentication() {
         return new PasswordAuthentication(
              authUser, authPassword.toCharArray());
     }
   }
);

System.setProperty("http.proxyHost", someProxyURl);
System.setProperty("http.proxyPort", someProxyPort);
System.setProperty("http.proxyUser", someProxyUser);
System.setProperty("http.proxyPassword", someProxyPassword);
....

`proxyUser` and `proxyPassword` are for the Apache HTTP client. They do nothing in the JDK. Setting the `Authenticator` is sufficient. — user207421, Mar 16 '17 at 18:18
