mainactivity.java

 public class mainactivity extends activity {  public int currentimageindex=0; timer timer; timertask task; imageview slidingimage;  private int[] image_ids = {         r.drawable.one, r.drawable.two, r.drawable.three,r.drawable.four,r.drawable.five,         r.drawable.six,r.drawable.seven, r.drawable.eight, r.drawable.nine,          };  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      final handler mhandler = new handler();      // create runnable posting     final runnable mupdateresults = new runnable() {         public void run() {              animateandslideshow();                       }     };      int delay = 1000; // delay 1 sec.      int period = 8000; // repeat every 4 sec.      timer timer = new timer();      timer.scheduleatfixedrate(new timertask() {      public void run() {           mhandler.post(mupdateresults);     }      }, delay, period);              }  public void onclick(view v) {      finish();     android.os.process.killprocess(android.os.process.mypid());   }  private void animateandslideshow() {  sharedpreferences getprefs = preferencemanager         .getdefaultsharedpreferences(getbasecontext());  boolean animation_two = getprefs.getboolean("animation_two", true);              boolean animation = getprefs.getboolean("animation", false); boolean animation_one = getprefs.getboolean("animation_one", false);          if (animation_two == true) {     slidingimage = (imageview)findviewbyid(r.id.imageview3_left);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);      currentimageindex++;      animation rotateimage = animationutils.loadanimation(this, r.anim.custom_anim);        slidingimage.startanimation(rotateimage);         finish(); }else if(animation_one == true) {     slidingimage = (imageview)findviewbyid(r.id.imageview3_left);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);      currentimageindex++;      animation rotateimage = animationutils.loadanimation(this, r.anim.fade_in);        slidingimage.startanimation(rotateimage);                    finish();  }else if (animation == true) {      slidingimage = (imageview)findviewbyid(r.id.imageview3_left);         slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);          currentimageindex++;          animation rotateimage = animationutils.loadanimation(this, r.anim.fade_in2);            slidingimage.startanimation(rotateimage);                   finish();      } else if(animation_two == false && animation == false && animation_one == false){     slidingimage = (imageview)findviewbyid(r.id.imageview3_left);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);      currentimageindex++;      animation rotateimage = animationutils.loadanimation(this, r.anim.fade_in2);    slidingimage.startanimation(rotateimage);     finish(); } }  @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.main, menu);     return true; }  @override public boolean onoptionsitemselected(menuitem item) {     // todo auto-generated method stub     switch (item.getitemid()) {      case r.id.action_settings:         intent p = new intent("com.test.demo.setting");         startactivity(p);     break;          } return false;  } }

rearrange code , work fine below:

 public class mainactivity extends activity {  public int currentimageindex=0; timer timer; timertask task; imageview slidingimage;  private int[] image_ids = {     r.drawable.one, r.drawable.two, r.drawable.three,r.drawable.four,r.drawable.five,     r.drawable.six,r.drawable.seven, r.drawable.eight, r.drawable.nine,      };  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     final handler mhandler = new handler();  // create runnable posting     final runnable mupdateresults = new runnable() {         public void run() {              animateandslideshow();                       }     };      int delay = 1000; // delay 1 sec.      int period = 8000; // repeat every 4 sec.      timer timer = new timer();      timer.scheduleatfixedrate(new timertask() {      public void run() {           mhandler.post(mupdateresults);     }      }, delay, period);               }        private void animateandslideshow() {      sharedpreferences getprefs = preferencemanager             .getdefaultsharedpreferences(getbasecontext());      boolean animation_two = getprefs.getboolean("animation_two", true);                          boolean animation = getprefs.getboolean("animation", false);             boolean animation_one = getprefs.getboolean("animation_one", false);   if (animation == true) {        slidingimage = (imageview)findviewbyid(r.id.imageview_slide);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);            currentimageindex++;     animation rotateimage = animationutils.loadanimation(this, r.anim.custom_anim);                      slidingimage.startanimation(rotateimage);     }else if(animation_one == true) {     slidingimage = (imageview)findviewbyid(r.id.imageview_slide);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);            currentimageindex++;             animation rotateimage = animationutils.loadanimation(this, r.anim.fade_in);               slidingimage.startanimation(rotateimage);     }else if (animation_two == true) {     slidingimage = (imageview)findviewbyid(r.id.imageview_slide);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);            currentimageindex++;     animation rotateimage = animationutils.loadanimation(this, r.anim.fade_in2);              slidingimage.startanimation(rotateimage);    }else if(animation == false && animation_one == false && animation_two == false){     slidingimage = (imageview)findviewbyid(r.id.imageview_slide);     slidingimage.setimageresource(image_ids[currentimageindex%image_ids.length]);            currentimageindex++;     animation rotateimage = animationutils.loadanimation(this, r.anim.fade_in2);               slidingimage.startanimation(rotateimage);  } } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.main, menu); return true;   }  @override public boolean onoptionsitemselected(menuitem item) { // todo auto-generated method stub switch (item.getitemid()) {  case r.id.action_settings:     intent p = new intent("com.test.demo.setting");     startactivity(p); break;      } return false;  } }

assembly - 8086 TASM: Illegal Indexing Mode -

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
