and myarrayadapter.java -

public class myarrayadapter extends arrayadapter<string> { context context; string[] values;  public myarrayadapter(context context, string[] values) {         super(context, r.layout.activity_main, values);         // todo auto-generated constructor stub         this.context = context;         this.values = values;      }        @override     public view getview(int position, view convertview, viewgroup parent) {         // todo auto-generated method stub          layoutinflater inflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service);         view v = inflater.inflate(r.layout.activity_main, parent, false);         textview txtv = (textview) v.findviewbyid(r.id.member_name);         textview txtv1 = (textview) v.findviewbyid(r.id.status);         imageview imgv = (imageview)v.findviewbyid(r.id.profile_pic);         bitmap icon = bitmapfactory.decoderesource(context.getresources(), r.drawable.ok);         for(int pos = 0; pos<values.length;pos++)         {             txtv.settext(values[position]);             imgv.setimagebitmap(icon);          }                 return v;     }  } 

please help!

you should load contact , pass result adapter in background service e.g. asynctask, intentservice running long operations on ui thread crash application.
