java - Check SD Card after Saving Image (Android) -

-

i have intent when complete, saves image /sdcard/aperture. while image save, not show image saved. problem? tried using scan broadcast in on activity result causes crash, , not scan image. 

@override protected void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);     if (requestcode == settings_request && resultcode == activity.result_ok) {         mediafragment content = (mediafragment) getfragmentmanager().findfragmentbyid(com.marlonjones.aperture.r.id.content_frame);         if (content != null) content.reload();         reloadnavdraweralbums();     }     if (requestcode == new_picture) {         // return file upload         if (resultcode == activity.result_ok) {             uri uri = null;             if (data != null) {                 uri = data.getdata();             }             if (uri == null && mcamerafilename != null) {                 uri = uri.fromfile(new file(mcamerafilename));             }         }     } }   final private int request_code_ask_permissions = 123; int currentapiversion = android.os.build.version.sdk_int; public void camera(menuitem menu) {     if (android.os.build.version.sdk_int >= build.version_codes.m) {         int hascamerapermission = checkselfpermission(manifest.permission.camera);         if (hascamerapermission != packagemanager.permission_granted) {             requestpermissions(new string[]{manifest.permission.camera},                     request_code_ask_permissions);             return;         }         intent intent = new intent();         intent.setaction(mediastore.action_image_capture);         date date = new date();         dateformat df = new simpledateformat("-mm-ss");          string newpicfile = "ph" + df.format(date)+".jpg";         string outpath = "/sdcard/aperture/" + newpicfile;         file outfile = new file(outpath);         mcamerafilename = outfile.tostring();         uri outuri = uri.fromfile(outfile);         intent.putextra(mediastore.extra_output, outuri);         startactivityforresult(intent, new_picture);     } else{         intent intent = new intent();         intent.setaction(mediastore.action_image_capture);         date date = new date();         dateformat df = new simpledateformat("-mm-ss");          string newpicfile = "ph" + df.format(date) + ".jpg";         string outpath = "/sdcard/aperture/" + newpicfile;         file outfile = new file(outpath);         mcamerafilename = outfile.tostring();         uri outuri = uri.fromfile(outfile);         intent.putextra(mediastore.extra_output, outuri);         startactivityforresult(intent, new_picture);} }

impression uses mediascannerconnection in places believe. it's more modern version of using scanner intent. tells when scanning complete , gives new uri (or null if file removed media database). 

mediascannerconnection.scanfile(this,           new string[] { filepath }, null,           new mediascannerconnection.onscancompletedlistener() {       @override       public void onscancompleted(string path, uri uri) {           log.i("externalstorage", "scanned " + path + ":");           log.i("externalstorage", "-> uri=" + uri);       } });

you'd want reload media , albums after scanning complete.
