java - Reloading a WebView with a JavaScript call from a loaded web page -

i have webview in app loads specific web page.

on web page button uses javascript call method within android activity reload url in webview (effectively resetting web app default state).

i've got of javascript interface android bit working few threads here , can pop toast show app reload, i'm getting error webview.loadurl() call follows.

java.lang.runtimeexception: java.lang.throwable: webview method called on thread 'javabridge'. webview methods must called on same thread. (expected looper looper (main, tid 1) {1d015c84} called on looper (javabridge, tid 122148) {33703881}, fyi main looper looper (main, tid 1) {1d015c84}) 

i'm guessing because method doing reload not within oncreate method activity of other webview stuff i'm not sure if problem , how resolve if - method reloads url needs within javascripinterface class reachable within web-page.

loading page in webview componenet (or reloading) needs done on ui thread reason, wrapping reload call in runonuithread resolves issue.

    @javascriptinterface     public void reloadsite(){         toast.maketext(mcontext, getstring(r.string.reloadingwebapp), toast.length_long).show();         runonuithread(new runnable() {             @override             public void run() {                 mwebview = (webview) findviewbyid(r.id.activity_main_webview);                 mwebview.loadurl(getstring(r.string.web_app_url));             }         });     }
