below oncreatemethod

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      // here instantiate java class retrieving https url result     myhttpclient client =  new myhttpclient();      // read input stream     textview textview =  (textview)findviewbyid(r.id.tvresult);      // setting output text view     textview.settext(client.getwebsiteresult()); } 

according answer here.

android.permission.interact_across_users_full signature level permission. app not able use until , unless has same signature system.

which not can achieve unless either creator or system build, or collaborating them such willing sign apk certificate. in other words, off limits developers.

however, reading loagcat , code.

above error suggests network call cannot made on main thread. so, make new thread , start network call thread. might solve problem.

new thread() {   public void run() {     // network call   } }.start(); 

if want have callbacks , stuff can use asynctask well.

also suggestion, making nice , quick network calls can use volley. personal favorite , easy use!
