JavaScript Working When Access From Internet But Not Responding When Access Page From Folder Assets On WebView Android -

i try access page url : demo face tracker using android webview. , using code:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);       wv = (webview) findviewbyid(r.id.webview);     wv.setwebchromeclient(new webchromeclient());     wv.setwebviewclient(new webviewclient(){         @override         public void onpagefinished(webview view, string url) {             super.onpagefinished(view, url);         }     });     wv.getsettings().setjavascriptenabled(true);     wv.addjavascriptinterface(new webappinterface(this), "android");     wv.loadurl("http://auduno.github.io/clmtrackr/clm_image.html"); } 

and works!

but when copy of page (include javascript) local, , access form assets folder app return not responding.

this code use access local assets:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);       wv = (webview) findviewbyid(r.id.webview);     wv.setwebchromeclient(new webchromeclient());     wv.setwebviewclient(new webviewclient(){         @override         public void onpagefinished(webview view, string url) {             super.onpagefinished(view, url);         }     });     wv.getsettings().setjavascriptenabled(true);     wv.addjavascriptinterface(new webappinterface(this), "android");     wv.loadurl("file:///android_asset/index.html"); } 

for information, of assets (scripts, css, etc) except media has combined single page , when access browser (on computer) working, not in android webview.

whether on android has special permission this? please :) thank you.

most have pathing issue. might not loading think does. try adding see

        @override         public void onloadresource(webview view, string resurl) {             super.onloadresource(view, resurl);             log.d(log_tag,"loading " + resurl);         } 

add setallowuniversalaccessfromfileurls address javascript security issue when loading file.

wv.getsettings().setallowuniversalaccessfromfileurls(true);
