Hello vamsi,

in this line :darrow:

you are trying to retrieve a (Text)View you should have defined in the xml layout using the id: "R.id.ws_response"

Using java Syntax Highlighting

TextView resultado=(TextView)findViewById(R.id.ws_response);
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

You'll have to add the following line to the TextView:

Using xml Syntax Highlighting

android:id="@+id/ws_response"
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

to make that View accessible from java code.
