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); } reference link here
