How to update webview?

How to update webview? - android

I need to update my webview because doesnt show anything until i rotate the screen.
My Webview
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.myfragment3, container, false);
webview = (WebView)v.findViewById(R.id.WebView);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setDomStorageEnabled(true);
webview.setLayerType(View.LAYER_TYPE_HARDWARE, null);
webview.setWebChromeClient(new WebChromeClient());
String url = "http://www.acr-sl.com/catalogo/1/1/1";
webview.loadUrl(url);
return v;
}
UPDATE: Finally solved this problem creating the webview from 0 ina new fragment, the only thing it changed were the layouts so the problem was derived from there i suppose.

my Layout file fragment_meru_detail is as
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/pageload"
android:layout_gravity="center"
android:text="Loding........"
/>
<WebView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="#+id/meruweb"
></WebView>
</LinearLayout>
My Java Class is as:
package com.rayz.digitalpostbox.fragments;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
import android.widget.TextView;
import android.widget.Toast;
import com.rayz.digitalpostbox.R;
import com.rayz.digitalpostbox.activities.HomeActivity;
public class MeruDetail extends Fragment {
TextView pageload ;
WebView webview ;
private ProgressBar progres;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_meru_detail, container, false);
((HomeActivity)getActivity()).setTitle("MERU Cabs");
webview = (WebView) rootView.findViewById(R.id.meruweb);
pageload = (TextView) rootView.findViewById(R.id.pageload);
progres = (ProgressBar)rootView.findViewById(R.id.progressBar);
progres.setMax(100);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
webview.getSettings().setSupportZoom(true);
webview.loadUrl("http://merucabs.com/mobile/");
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
MeruDetail.this.setValue(progress);
super.onProgressChanged(view, progress);
if(progress==100){
progres.setVisibility(View.GONE);
}else {
progres.setVisibility(View.VISIBLE);
}
if(progress>40){
pageload.setVisibility(View.GONE);
}
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getActivity(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
MeruDetail.this.progres.setProgress(0);
return rootView ;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
public void setValue(int progress) {
this.progres.setProgress(progress);
}
#Override
public void onPause() {
super.onPause();
((HomeActivity)getActivity()).setTitle("Dashboard");
}
}
And I think you should also check in your mainfest file for internet permission
<uses-permission android:name="android.permission.INTERNET" />

You can use this for your WebView
webview.reload()

you can webView.reload() but be aware this reposts a page if the request was POST, so only works correctly with GET.
If your URL is static or same then you should use loadURL again it's better.
YourActivity.this.webView.loadUrl("http://www.website.com");

below is working code for your requirement have look and implement it as>
Layout file is as:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

Is Flashplayer installed on your Phone?
I had to install an older Flash Version on my Device, as Adobe stopped Support for Android a while ago, FLV Playback in Webview doesn't work with newer Android Versions.

Android webview geo: and tel: links

I made android web app which uses WebView. The problem is when I press the geo: or tel: links it stops working. I tried a lot of tips from here, but non of them actualy work.

I'm pretty new to this, and I took this instructions to make the app https://developers.google.com/chrome/mobile/docs/webview/gettingstarted
So, can anybody try to fill what is missing to make it to not crash when geo: or tel: link is pressed and handle the geo: and tel: links like in chrome?
I found the answer!!!
I replaced this code in MyAppWebViewClient.java
public class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().endsWith("example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
with this one
public class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost() != null && Uri.parse(url).getHost().equals("domain.com"))
{
return false;
}
else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}

How to open two webviews in one screen using fragments

could any one help me in figuring out how to open two webviews in the same screen using fragments Android,each webview must display a certain web page for example :1-google,2,yahoo.
i've tried too many tutorials and samples .nothing works fine for me... :(
The main issue for me that conflicting my thoughts, is what to write in the fragment class to open a webView and what to write in the main activity that runs the whole app .
Thanks in advance for any help.. :)
here is my code that runs fine for the portrait mode with one screen and crashes on landscape mode:
package com.example.androidwebviewfragment;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Fragment1 extends Fragment {
WebView myWebView;
final static String myBlogAddr = "http://android-er.blogspot.com";
String myUrl;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.layout_webfragment,container,false);
myWebView = (WebView)view.findViewById(R.id.mywebview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new MyWebViewClient());
if(myUrl == null){
myUrl = myBlogAddr;
}
myWebView.loadUrl(myUrl);
return view;
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
myUrl = url;
view.loadUrl(url);
return true;
}
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
setRetainInstance(true);
}
}
and here is the second fragment :
package com.example.androidwebviewfragment;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Fragment2 extends Fragment {
WebView myWebView;
final static String myBlogAddr = "http://android-er.blogspot.com";
String myUrl;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate
(R.layout.layout_webfragment2,container,false);
myWebView = (WebView)view.findViewById(R.id.mywebview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new MyWebViewClient());
if(myUrl == null){
myUrl = myBlogAddr;
}
myWebView.loadUrl(myUrl);
return view;
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
myUrl = url;
view.loadUrl(url);
return true;
}
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
setRetainInstance(true);
}
}
And here is the main activity:
package com.example.androidwebviewfragment;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
/* (non-Javadoc)
* #see android.app.Activity#onCreate(android.os.Bundle)
*/
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
the .xml files are :
1-Fragment 1 :
<WebView
android:id="#+id/mywebview"
android:layout_height="match_parent"
android:layout_width="match_parent" />
</LinearLayout>
2-fragment 2 :
</LinearLayout>
3-main xml layout:
<fragment
android:name="com.example.androidwebviewfragment.Fragment1"
android:id="#+id/myweb_fragment1"
android:layout_height="match_parent"
android:layout_width="match_parent" />
<fragment
android:name="com.example.androidwebviewfragment.Fragment2"
android:id="#+id/myweb_fragment2"
android:layout_height="match_parent"
android:layout_width="match_parent" />
</RelativeLayout>
And this is the main.xml in the layout-land folder:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

<fragment
android:name="com.example.androidwebviewfragment.Fragment2"
android:id="#+id/myweb_fragment"
android:layout_height="match_parent"
android:layout_width="match_parent" />

The error on land scape mode from log:
java.lang.RuntimeException:
Unable to start activity ComponentInfo{com.example.androidwebviewfragment
/com.example.androidwebviewfragment.MainActivity}
:android.view.InflateException: Binary XML file line #12: Error inflating class fragment

In the fragment class you create view and returns it to main activity and in the mainactivity you create a fragmentadapter to bind fragments.

How to load external webpage in WebView

My problem is that the webpage is not loaded inside the WebView.
mWebview.loadUrl("http://www.google.com"); launches the web browser...
This is the code of my activity:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class Main extends Activity {
private WebView mWebview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.loadUrl("http://www.google.com");
setContentView(mWebview);
}
}
I added the required permission in the Manifest:
<uses-permission android:name="android.permission.INTERNET" />

Thanks to this post, I finally found the solution. Here is the code:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
import android.annotation.TargetApi;
public class Main extends Activity {
private WebView mWebview ;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
#SuppressWarnings("deprecation")
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
#TargetApi(android.os.Build.VERSION_CODES.M)
#Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
// Redirect to deprecated method, so you can use it in all SDK versions
onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}
});
mWebview .loadUrl("http://www.google.com");
setContentView(mWebview );
}
}

try this
webviewlayout.xml:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/help_webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none"
/>
In your Activity:
WebView webView;
setContentView(R.layout.webviewlayout);
webView = (WebView)findViewById(R.id.help_webview);
webView.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.com");
Update
Add webView.setWebViewClient(new WebViewController()); to your Activity.
WebViewController class:
public class WebViewController extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}

public class WebViewController extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
webView.setWebViewClient(new WebViewController());

Please use this code:-
Main.Xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="#drawable/background">
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#drawable/top_heading"
android:id="#+id/rlayout1">
<TextView android:layout_width="wrap_content"
android:layout_centerVertical="true" android:layout_centerHorizontal="true"
android:textColor="#ffffff" android:textSize="22dip"
android:textStyle="bold" android:layout_height="wrap_content"
android:text="More Information" android:id="#+id/txtviewfbdisplaytitle" />
</RelativeLayout>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_below="#+id/rlayout1"
android:id="#+id/rlayout2">
<WebView android:id="#+id/webview1" android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1.0" />
</RelativeLayout>
</RelativeLayout>
MainActivity.Java
public class MainActivity extends Activity {
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Button btnBack;
WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview=(WebView)findViewById(R.id.webview1);
webview.setWebViewClient(new MyWebViewClient());
openURL();
}
/** Opens the URL in a browser */
private void openURL() {
webview.loadUrl("http://www.google.com");
webview.requestFocus();
}
}
Try this code if any query ask me.

It's very simple try integrate these lines of code
first take permission in the Android Manifest file
<uses-permission android:name="android.permission.INTERNET" />
then write some code in you Activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.MainActivity">
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/help_webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
Then write these code in your MainActivity.java
import android.app.Activity;
import android.content.Intent;
import android.content.res.Resources;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.webkit.WebResourceRequest;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class MainActivity extends Activity{
private WebView mWebview ;
String link = "";// global variable
Resources res;// global variable
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_modernherbal_main);
mWebview = (WebView) findViewById(R.id.help_webview);
WebSettings webSettings = mWebview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
mWebview .loadUrl("http://www.example.com");
}
}
Try this it'll help you to solve your problem

just go into XML file and give id to your webView then in java paste these line:
public class Main extends Activity {
private WebView mWebview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.Your_layout_file_name);
mWebview = (WebView)findViewById(R.id.id_you_gave _to_your_wenview_in_xml);
mWebview.loadUrl("http://www.google.com");
}
}

I used this code that was cool. but have an error. " neterr_cleartext_not_permitted"
show when you use this code then you will face this problem..
I got a solution of this.you have to add this in your AndroidManifest.xml near about Application
android:usesCleartextTraffic="true"
<uses-permission android:name="android.permission.INTERNET" /> // ignore if you already added. outside of Application.

You can do like this.
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("Your URL goes here");

try this;
webView.loadData("<iframe src='http://www.google.com' style='border: 0; width: 100%; height: 100%'></iframe>", "text/html; charset=utf-8", "UTF-8");

Add Internet permission in AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
In your Layout:
<?xml version="1.0" encoding="utf-8"?>
<WebView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView"
/>
In your Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
progressDialog = new ProgressDialog(this);
url_Api = "https://learn.microsoft.com/en-us/learn";
webView = this.findViewById(R.id.webView);
progressDialog.setMessage(getString(R.string.connection_Wait));
progressDialog.setIndeterminate(false);
progressDialog.setCancelable(true);
progressDialog.show();
LoadUrlWebView( url_Api );
}catch (Exception e){
Log.w(TAG, "onCreate", e);
}
}
private void LoadUrlWebView( String url_api ) {
try {
webView.setWebViewClient(new WebViewClient());
webView.setWebChromeClient(new MyWebChromeClient( url_api ));
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setAllowContentAccess(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setDisplayZoomControls(false);
webView.loadUrl(url_api);
} catch (Exception e) {
Log.w(TAG, "setUpNavigationView", e);
}
}
private class MyWebChromeClient extends WebChromeClient {
private String urlAccount;
public MyWebChromeClient( String urlAccount ) {
this.urlAccount = urlAccount;
}
#Override
public void onProgressChanged(WebView view, int newProgress) {
try {
//Tools.LogCat(context, "INSIDE MyWebChromeClient | onProgressChanged / newProgress1:" + newProgress);
progressDialog.setMessage(newProgress + "% " + getString(R.string.connection_Wait));
if (newProgress < 100 && !progressDialog.isShowing()) {
if (progressDialog != null)
progressDialog.show();
}
if (newProgress == 100) {
if (progressDialog != null)
progressDialog.dismiss();
}
}catch (Exception e){
Log.w( "onProgressChanged", e);
}
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
sharedPreferences = new Shared_Preferences( context );
sharedPreferences.setPageWebView(view.getUrl());
}
}

Add WebView Client
mWebView.setWebViewClient(new WebViewClient());

You need to add WebView client
mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
// do your stuff here
}
});
also you can use onPageFinished to do task after webview done loading web page

activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

</androidx.constraintlayout.widget.ConstraintLayout>
MainActivity.java:
package com.example.myapplication;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView .loadUrl("http://www.google.com");
webView.setWebViewClient(new MyWebViewClient());
}
}
AndroidManifest.xml: (add uses-permission and android:usesCleartextTraffic)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapplication">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:usesCleartextTraffic="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.MyApplication">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Simple Webview activity in kotlin :
class WebViewActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
intent.getStringExtra(URL_EXTRA)?.let { url ->
WebView(this).apply {
settings.javaScriptEnabled = true // check if your need this
settings.domStorageEnabled = true
settings.setSupportZoom(true)
settings.builtInZoomControls = true
settings.displayZoomControls = false
loadUrl(url)
setContentView(this)
}
}
}
companion object {
const val URL_EXTRA = "url"
}
}

Add below method in your activity class.Here browser is nothing but your webview object.
Now you can view web contain page wise easily.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && browser.canGoBack()) {
browser.goBack();
return true;
}
return false;
}

How to update webview? - android

You can use this for your WebView webview.reload()

you can webView.reload() but be aware this reposts a page if the request was POST, so only works correctly with GET. If your URL is static or same then you should use loadURL again it's better. YourActivity.this.webView.loadUrl("http://www.website.com");
