java - Android - how can i onCreate launch the camera without crashing the apps? -


i have problem, first activity window launching second activity window need directly see cam preview > take snap shot > show preview on activity window.

now, way need launch (expected , correct way of user demand), after taking picture , coming window apps crash on way.

  @override   public void oncreate(bundle savedinstancestate) {       super.oncreate(savedinstancestate);       setcontentview(r.layout.activity_main);       this.imageview = (imageview)this.findviewbyid(r.id.picture);       button photobutton = (button) this.findviewbyid(r.id.capture_btn);       //photobutton.setonclicklistener(new view.onclicklistener() {            //@override           //public void onclick(view v) {               intent cameraintent = new intent(android.provider.mediastore.action_image_capture);                startactivityforresult(cameraintent, camera_request);           // }       //});   }

but way not crash, in way wrong use case, cause becomes 2 button press apps.

public class mainactivity extends activity  implements onclicklistener {   private static final int camera_request = 1888;   private static final int pic_crop = 0;    private imageview imageview;    @override   public void oncreate(bundle savedinstancestate) {       super.oncreate(savedinstancestate);       setcontentview(r.layout.activity_main);       this.imageview = (imageview)this.findviewbyid(r.id.picture);       button photobutton = (button) this.findviewbyid(r.id.capture_btn);       photobutton.setonclicklistener(new view.onclicklistener() {            //@override           public void onclick(view v) {               intent cameraintent = new intent(android.provider.mediastore.action_image_capture);                startactivityforresult(cameraintent, camera_request);            }       });   }    protected void onactivityresult(int requestcode, int resultcode, intent data) {       if (requestcode == camera_request && resultcode == result_ok) {           bitmap photo = (bitmap) data.getextras().get("data");          imageview.setimagebitmap(photo);     }     }    @override   public void onclick(view arg0) {     // todo auto-generated method stub    }   }
