so noticed till first line there seems no problem i.e url = new url...,(even bare http request done through browser, return info need )

and manifest entry looks like

<uses-permission android:name="android.permission.internet"></uses-permission> 

below logcat output

05-02 18:36:32.804: d/androidruntime(902): shutting down vm 05-02 18:36:32.804: w/dalvikvm(902): threadid=1: thread exiting uncaught exception (group=0x409c01f8) 05-02 18:36:33.113: e/androidruntime(902): fatal exception: main 05-02 18:36:33.113: e/androidruntime(902): android.os.networkonmainthreadexception 05-02 18:36:33.113: e/androidruntime(902): @ android.os.strictmode$androidblockguardpolicy.onnetwork(strictmode.java:1099) 05-02 18:36:33.113: e/androidruntime(902): @ java.net.inetaddress.lookuphostbyname(inetaddress.java:391) 05-02 18:36:33.113: e/androidruntime(902): @ java.net.inetaddress.getallbynameimpl(inetaddress.java:242) 05-02 18:36:33.113: e/androidruntime(902): @ java.net.inetaddress.getallbyname(inetaddress.java:220) 05-02 18:36:33.113: e/androidruntime(902): @ libcore.net.http.httpconnection.<init>(httpconnection.java:71)

so knows im going wrong

this key error in logcat message --> android.os.networkonmainthreadexception. should move network access background thread. can use either intentservice, asynchtask, handler, etc. accomplish this.
