public class mainactivity extends actionbaractivity {     private static final int picture_request_code = 100;     public button camera, gallery;     private uri fileuri;     private static file mediafile;     imageview image;     public string filename;     @override      protected void oncreate(bundle savedinstancestate) {         system.out.println("started main activity");         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         camera = (button) findviewbyid(r.id.button1);         gallery = (button) findviewbyid(r.id.button2);         createlisteners();     }     private static uri getoutputmediafile(){         file mediastoragedir = new file(environment.getexternalstoragepublicdirectory(environment.directory_pictures), "mustache");         if (! mediastoragedir.exists()){             if (! mediastoragedir.mkdirs()){                 log.d("mycameraapp", "failed create directory");                 return null;             }         }         string timestamp = new simpledateformat("yyyymmdd_hhmmss").format(new date());         mediafile = new file(mediastoragedir.getpath() + file.separator + "img_"+ timestamp + ".jpg");          return uri.fromfile(mediafile);     }     public void launchcamera(){         intent intent = new intent(mediastore.action_image_capture);         fileuri = getoutputmediafile(); // create file save image         intent.putextra(mediastore.extra_output, fileuri);         startactivityforresult(intent, picture_request_code);      }     public void launchgallery(){         intent gallery = new intent(intent.action_pick,android.provider.mediastore.images.media.external_content_uri);         fileuri = getoutputmediafile(); // create file save image         gallery.putextra(mediastore.extra_output, fileuri);         startactivityforresult(gallery, picture_request_code);      }      @override     public boolean oncreateoptionsmenu(menu menu) {          // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }     public void onactivityresult(int requestcode, int resultcode, intent data) {            super.onactivityresult(requestcode, resultcode, data);                system.out.println(string.valueof(requestcode));                system.out.println(string.valueof(resultcode));                system.out.println(data);                intent mediascanintent = new intent(intent.action_media_scanner_scan_file);                uri contenturi = uri.fromfile(mediafile);                mediascanintent.setdata(contenturi);                this.sendbroadcast(mediascanintent);      }     public static final int media_type_video = 2;      private void createlisteners() {         system.out.println("started createlisteners main activity");         camera.setonclicklistener(new onclicklistener() {             public void onclick(view v) {                 launchcamera();             }          });          gallery.setonclicklistener(new onclicklistener() {             public void onclick(view v) {                 launchgallery();             }         });     }   } 

xml:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/container"     android:layout_width="match_parent"     android:layout_height="fill_parent"     android:orientation="horizontal"     tools:context="com.example.mustache.mainactivity"     tools:ignore="mergerootframe" >      <button         android:id="@+id/button1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="bottom"         android:layout_weight="1"         android:text="@string/main_camera_button" />      <button         android:id="@+id/button2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"          android:layout_gravity="bottom"         android:layout_weight="1"         android:text="@string/main_gallery_button" />  </linearlayout> 

however, app takes photo , saves gallery, returns main screen without doing anything. how make display photo?

the problem not displaying captured image.

you need add imageview in layout , set captured image in onactivityresult

change onactivityresult this

public void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);     uri contenturi = uri.fromfile(mediafile);      imageview imageview = (imageview)findviewbyid(r.id.imageview1);     imageview.setimageuri(contenturi); } 

also, add imageview in layout

<imageview     android:id="@+id/imageview1"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_gravity="center"     android:layout_weight="1"/>
