i have tried can find online nothing seems fix it. code camera stuff.

btnphoto.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 intent takepictureintent = new intent(mediastore.action_image_capture);                 if (takepictureintent.resolveactivity(getpackagemanager()) != null) {                    // file file = new file(...);                     startactivityforresult(takepictureintent, activity_start_camera);                    // takepictureintent.putextra(mediastore.extra_output, uri.fromfile(file));                 }             }         });        }

and

 @override     protected void onactivityresult(int requestcode, int resultcode, intent data) {         if (requestcode == activity_start_camera) {             if (data != null && resultcode == result_ok) {                 // image captured , saved file                 bundle extras = data.getextras();                 bitmap imagebitmap = (bitmap) extras.get("data");                 imageview.setimagebitmap(imagebitmap);             } else {                 // user cancelled image capture or                 // image capture failed, advise user              }         }         super.onactivityresult(requestcode, resultcode, data);     }

this code make camera works. may try this.

 private void activetakephoto() {         intent takepictureintent = new intent(mediastore.action_image_capture);         startactivityforresult(takepictureintent, request_image_capture);     }      @override     protected void onactivityresult(int requestcode, int resultcode,                                     intent data) {         super.onactivityresult(requestcode, resultcode, data);         switch (requestcode) {             case request_image_capture:                 if (requestcode == result_load_image && resultcode == result_ok & null != data) {                  bitmap thumbnail = (bitmap) data.getextras().get("data");                 bytearrayoutputstream bytes = new bytearrayoutputstream();                 thumbnail.compress(bitmap.compressformat.jpeg, 90, bytes);                 //to generate random file name                 string filename = "tempimg.jpg";                  try {                     photo = (bitmap) data.getextras().get("data");                     //captured image set in imageview                     imageview.setimagebitmap(photo);                 } catch (exception e) {                     e.printstacktrace();                 }         }     }
