Ok   I have looked EVERYWHERE and my little brain just can t understand a better way to refresh an activity   Any suggestions that I can understand would be great      Here is the java code  package com dge dges   import android app Activity  import android content Intent  import android os Bundle  import android view View  import android webkit WebView  import android widget Button   public class dgeActivity extends Activity        WebView mWebView           Called when the activity is first created          Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout main            mWebView    WebView  findViewById R id webview           mWebView getSettings            mWebView loadUrl  quot http   www websitehere php quot                     Button newButton    Button findViewById R id new button           newButton setOnClickListener new View OnClickListener                 public void onClick View v                    Intent intent   new Intent dgeActivity this  dgeActivity class                   startActivity intent                                      And here is the main xml  lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt   lt RelativeLayout     xmlns android  quot http   schemas android com apk res android quot      android id  quot   id RelativeLayout quot      android layout width  quot fill parent quot      android layout height  quot fill parent quot      android background  quot  000000 quot  gt        lt WebView         android id  quot   id webview quot          android layout width  quot fill parent quot           android layout height  quot wrap content quot          android scrollbars  quot none quot   gt        lt Button         android id  quot   id new button quot          android layout width  quot fill parent quot          android layout height  quot wrap content quot          android layout alignParentBottom  quot true quot          android layout centerHorizontal  quot true quot          android text  quot Refresh quot   gt    lt  RelativeLayout gt   I don t like the idea of just re-stacking activity after activity   There has to be an easier way to refresh the webview   Please help

Yes for some reason WebView reload   causes a crash if it failed to load before  something to do with the way it handles history   This is the code I use to refresh my webview  I store the current url in self url    1  Pause timeout and page loading  self timeout pause   sleep 1     2  Check for internet connection  Really lazy way   while self page   networkAccessManager   networkAccessible      QNetworkAccessManager NotAccessible  sleep 2     3 Try again  if self url    self page   mainFrame   url        self page   action QWebPage Reload      self timeout resume 60   else      self page   action QWebPage Stop      self page   mainFrame   load self url      self timeout resume 30   return False

Refreshing current webview s URL is not a common usage  I used this in such a scenario  When user goes to another activity and user come back to webview s activity I reload current URL like this   public class MyWebviewActivity extends Activity       WebView mWebView                                  Override     public void onRestart                 String url   mWebView getUrl                String postData   MyUtility getOptionsDataForPOSTURL mContext               mWebView postUrl url  EncodingUtils getBytes postData   BASE64               You can also use WebView s reload   function  But note that if you loaded the webview with postUrl    then mWebView reload    doesn t work  This also works  String webUrl   webView getUrl    mWebView loadUrl webUrl

Why not to try this   Swift code to call inside class   self mainFrame reload     or external call  myWebV mainFrame reload

User · Answer

You could call an mWebView reload    That s what it does

1  In case you want to reload the same URL   mWebView loadUrl  http   www websitehere php      so the full code would be  newButton setOnClickListener new View OnClickListener        public void onClick View v        dgeActivity this mWebView loadUrl  http   www websitehere php              2  You can also call mWebView reload   but be aware this reposts a page if the request was POST  so only works correctly with GET

This worked for me   just put under onCreate metode  Button button    Button  findViewById R id reload btn       button setOnClickListener new View OnClickListener             public void onClick View v                web loadUrl   javascript window location reload  true                                        This is the code  that can reload a website in a webView  web loadUrl   javascript window location reload  true

The best solution is to just do webView loadUrl   javascript window location reload  true        This should work on all versions and doesn t introduce new history entries
