use code in setwebchormeclinet.

  webview.setwebchromeclient(new webchromeclient() {          // openfilechooser android 3.0+         public void openfilechooser(valuecallback<uri> uploadmsg, string accepttype){                // update message             muploadmessage = uploadmsg;              try{                      // create androidexamplefolder @ sdcard                  file imagestoragedir = new file(                                        environment.getexternalstoragepublicdirectory(                                        environment.directory_pictures)                                        , "androidexamplefolder");                  if (!imagestoragedir.exists()) {                     // create androidexamplefolder @ sdcard                     imagestoragedir.mkdirs();                 }                  // create camera captured image file path , name                  file file = new file(                                 imagestoragedir + file.separator + "img_"                                 + string.valueof(system.currenttimemillis())                                  + ".jpg");                  mcapturedimageuri = uri.fromfile(file);                   // camera capture image intent                 final intent captureintent = new intent(                                               android.provider.mediastore.action_image_capture);                  captureintent.putextra(mediastore.extra_output, mcapturedimageuri);                  intent = new intent(intent.action_get_content);                  i.addcategory(intent.category_openable);                 i.settype("image/*");                  // create file chooser intent                 intent chooserintent = intent.createchooser(i, "image chooser");                  // set camera intent file chooser                  chooserintent.putextra(intent.extra_initial_intents                                        , new parcelable[] { captureintent });                  // on select image call onactivityresult method of activity                 startactivityforresult(chooserintent, filechooser_resultcode);                }              catch(exception e){                  toast.maketext(getbasecontext(), "exception:"+e,                              toast.length_long).show();              }          }          // openfilechooser android < 3.0         public void openfilechooser(valuecallback<uri> uploadmsg){             openfilechooser(uploadmsg, "");         }          //openfilechooser other android versions         public void openfilechooser(valuecallback<uri> uploadmsg,                                     string accepttype,                                     string capture) {              openfilechooser(uploadmsg, accepttype);         }
