use instead create delay

/** duration of wait **/     private final int splash_display_length = 1000;      /** called when activity first created. */     @override     public void oncreate(bundle icicle) {         super.oncreate(icicle);         setcontentview(r.layout.splashscreen);          /* new handler start menu-activity           * , close splash-screen after seconds.*/         new handler().postdelayed(new runnable(){             @override             public void run() {                 /* create intent start menu-activity. */                 intent mainintent = new intent(splash.this,menu.class);                 splash.this.startactivity(mainintent);                 splash.this.finish();             }         }, splash_display_length);     }
