android - Activity done(in application MyapplicationName)Not Responding? -

i have thread wating ontouchevent()

private runnable disconnectcallback = new runnable() {     @override     public void run() {     // perform required operation on disconnect                try {                     wait();                 } catch (interruptedexception e) {                     e.printstacktrace();                 }                  final logout l=new logout();                 l.setcontext(ac2.this);// passing context of ac3.java logout.java                 l.execute(sessid,uname);      } };   

when user touches screen oneventtouch() called

 public boolean oneventtouch(motionevent event) {              disconnectcallback.notify();             return true;           };
