Iam loading a url into a WebView. This is a login page. When the user is authenticated he is shown a page. I stop the loading at this point and start another activity.
When the login button is hit, the user is redirected to first url. I start a progress dialog at this point. After he reaches the authenticated page I want to stop the progress dialog and directly want to show the new activity. I dont want the user to see the authenticated page.
Right now the Progress dialog stops at the authenticated page. The user sees it and then he is shown the next activity
Any help on how this can be achieved?
Here is my code:-
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.loadUrl(url);
final ProgressDialog progressBar = ProgressDialog.show(Details1.this, "Loading..", "Please wait!");
myWebView.setWebViewClient(new WebViewClient()
{
#Override

I tested this code on lenovo, moto and MI devices...works fine but when I choose nexus device for loading url it gives the above stated error.
I am making a web view and trying to show loading message using progress Dialog.progress dialog is showing but not dismissed after all the content of URL is loaded.Please Help me.

Load webview code,
webViewInfo.getSettings().setJavaScriptEnabled(true);
webViewInfo.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webViewInfo.setWebViewClient(new MYWEBCLIENT());
webViewInfo.loadData("YOUR_URL_OR_HTML_FILE", "text/html", "UTF-8");
You can try this java code:
Just need to replace my entities with yours. Such as class name or other variables or stuff.
public class WebViewDemo extends Activity

You can run my java class to test, is it working or not at your end.
Hope this helps you.
I am developing an app in that when a user navigates from one link to another link I want to change the content of the edittext and want to show current url in the edittext.
But these 3 methods are not working, not even printing the logs. Here is the code.
wv.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
String url_new = view.getUrl();
Log.v("","Webview URL: "+url);
addressbar.setText(url_new);
return false;
}
#Override
public void onPageFinished(WebView view, String url)
{
// TODO Auto-generated method stub
super.onPageFinished(view, url);
String url_new = view.getUrl();
Log.v("","Webview Function URL: "+url_new);
addressbar.setText(url_new);
}

String url_new = view.getUrl();

addressbar.setText(url_new);

You're overwriting your WebViewClient in your AsyncTask object:
wv.setWebViewClient(new WebViewClient());
This overwrites your custom WebViewClient you set in Activity.onCreate().
You can probably get rid of the whole AsyncTask implementation, too. You can call loadUrl in a WebView in the UI thread with no problems. This might simplify things for you greatly.
i have more than 100 html files and i want each file to open on row click in listview and each html file should open in the webview , i tried this code but this is not working, only the webview opens on row click , the html file is not showing up.
package com.Example.apk;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.webkit.WebViewClient;
public class WebView extends Activity {
public class WebViewActivity extends Activity {
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_webview);
web = (WebView) findViewById(R.id.webview1);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
int pos = getIntent().getIntExtra("key",0);
if(pos==0)
{
web.loadUrl("file:///android_asset/work.html");
}
else if(pos==1)
{
web.loadUrl("file:///android_asset/work1.html");
}
else if(pos==2)
{
web.loadUrl("file:///android_asset/work2.html");
}
else if(pos==3)
{
web.loadUrl("file:///android_asset/work3.html");
}
// similarly for 4 and 5 and so on.
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override

String description, String failingUrl) {
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub

}
}
}
}
Pass the position to next Activity
list1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent myIntent = new Intent(MainActivtiy.this,WebViewActivity.class);
myIntent.putExtra("key",position);
startActivity(myIntent);
}
});
Then in WebViewActivity ie activity_webview)
public class WebViewActivity extends Activity {
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_webview);
web = (WebView) findViewById(R.id.webview1);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
int pos = getIntent().getIntExtra("key",0);
if(pos==0)
{
web.loadUrl("file:///android_asset/work.html");
}
else if(pos==1)
{
web.loadUrl("file:///android_asset/work1.html");
}
else if(pos==2)
{
web.loadUrl("file:///android_asset/work2.html");
}
else if(pos==3)
{
web.loadUrl("file:///android_asset/work3.html");
}
...// similarly for 4 and 5 and so on.
}

Make an entry for WebViewActivity in Manifest file.
For your purpose use this
WebView wv = (WebView)rootView.findViewById(R.id.go_web_view);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadDataWithBaseURL(null, description, "text/html", "utf-8", null);
Here "description" is name of string containing data with or without html tags
list1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String url = m_ArrayList.get(arg2).your_url;
Intent myIntent = new Intent(MainActivtiy.this,AppWebView.class);
myIntent.putExtra("key",url);
startActivity(myIntent);
}
});
If you need to render url then try
public class AppWebView extends Activity{
WebView webView;
ProgressBar pBar;
#SuppressLint("SetJavaScriptEnabled")
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.web_view);

if (extras == null) {
newUrl = null;
} else {
newUrl = extras.getString("url");
}
} else {
newUrl = (String) savedInstanceState
.getSerializable("myJsonStringS");
}
Log.d("jitendra", newUrl);
//SharedPreferences sp = getSharedPreferences("booking_detail", 0);
//String jsonString = sp.getString("jsonString", "");
webView = (WebView)findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new myWebClient());
webView.loadUrl(newUrl);

To create a webView recently I was using webViewClient. mWebView.setWebViewClient(new WebViewClient());
But I need to implement a progress bar. When user clicks a link, this progress bar will be visible. After page complete, progressbar will be hidden and webView will be visible. Regarding to this and this, So I added a WebChromeClient. But it loads first URL, but when I click a button inside my web page, a dialog opens and asks to open URL with which application.
I read that I should override shouldOverrideUrlLoading() method. but I get an error that "shouldOverrideUrlLoading" can't be overriden for WebChromeClient.
I would be happy if you can give an example that has progressbar and webView, also opens new URLs inside the same webView.
public class WebActivity extends Activity {
WebView mWebView;
ProgressBar mProgress;
Context mContext;
ProgressBar mProgressBar;
#Override
public void onCreate(Bundle savedInstanceState) {
this.mContext = getApplicationContext();
super.onCreate(savedInstanceState);
setContentView(R.layout.web);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebChromeClient(new myWebChromeClient());
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setUserAgentString("myApp");
mProgressBar = (ProgressBar) findViewById(R.id.webProgressBar);
mProgressBar.setMax(100);
}
public class myWebChromeClient extends WebChromeClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
#Override
public void onProgressChanged(WebView view, int newProgress) {
//WebActivity.this.setValue(newProgress);
super.onProgressChanged(view, newProgress);
}
}
}
try with this code
webView = (WebView) view.findViewById(R.id.transcationwebview);
progressdialog = ProgressDialog.show(mContext, "",
mContext.getString(R.string.please_wait));
progressdialog.setCancelable(true);
progressdialog.setOnCancelListener(new OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
webView.stopLoading();
// webView.clearView();
}
});
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new MyChromeClient());
webView.setWebViewClient(new WebViewClient() {
#Override

}
you can extends WebViewClient instead of WebChromeClient and override the onPageStarted to show the ProgressBar and dismiss it in onPageReceived
I made some changes in the Activity.
use WebViewClient instead of WebChromeClient
and also use ProgressDialog instead of ProgressBar
public class WebActivity extends Activity {
WebView mWebView;
Context mContext;
ProgressDialog mProgressBar;
private static final int DIALOG2_KEY = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
this.mContext = getApplicationContext();
super.onCreate(savedInstanceState);
setContentView(R.layout.web);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebViewClient(new MyWebChromeClient());
mWebView.getSettings().setBuiltInZoomControls(true);
showDialog(DIALOG2_KEY); }
#Override
protected void onResume() {
super.onResume();
mWebView.loadUrl("YOUR_URL");
}
private final class MyWebChromeClient extends WebViewClient {
#Override
public void onPageFinished(WebView view, String url) {
dismissDialog(DIALOG2_KEY);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("file")) {
return false;
} else{
view.loadUrl(url);
return true;
}
}
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id)
{
case DIALOG2_KEY:
{
mProgressBar.setMessage("Loading");
mProgressBar.setIndeterminate(true);
mProgressBar.setCancelable(false);
return mProgressBar;
}
}
return null;
}
}
Hope this help you
