My website is having one external link which directs to api.whatsapp.com once you click on the chat with us floating button on my website.
I have created a Webview Android application that opens my website in it. But when I click on the Chat With Us button then it gives me the error as there is no functionality to open it up.
Can anyone please tell me the code to fix this issue?
package com.GadgetGlaze.GadgetGlaze;
import androidx.appcompat.app.AppCompatActivity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private WebView mywebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mywebView=(WebView) findViewById(R.id.webview);
mywebView.setWebViewClient(new WebViewClient());
mywebView.loadUrl("https://www.gadgetglaze.com/");
WebSettings webSettings=mywebView.getSettings();
webSettings.setJavaScriptEnabled(true);
}
public class mywebClient extends WebViewClient{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
super.onPageStarted(view,url,favicon);

}
#Override

You should return false in your shouldOverrideUrlLoading when u want to handle links in the browser itself. Try this:
#Override
public boolean shouldOverrideUrlLoading(WebView view,String url){
view.loadUrl(url);
return false;
}
My Code :
My Adapter
#Override
public void onBindViewHolder(#NonNull SliderAdapter.SliderHolder holder, int position) {
final HomePage.ContentList item = homePageList.get(position);
SliderHolder viewHolder = (SliderHolder) holder;
viewHolder.txt_category.setText(item.getCategoryName());
viewHolder.title_item_list_pager.setText(item.getTitle());
if (item.getImage() != null)
Glide.with(holder.itemView).load(item.getImage()).into(viewHolder.img);
Log.d("TEST103-2", "PV");
viewHolder.img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), NewsDetail.class);
intent.putExtra("newsdetail",homePageList.get(position).getExternalUrl());
v.getContext().startActivity(intent);
}
});
}
news detail class
package com.platin.android;
import android.os.Bundle;
import android.webkit.WebView;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
public class NewsDetail extends AppCompatActivity {
WebView newsdetail;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.news_detail);
newsdetail = findViewById(R.id.newsdetail);
newsdetail.getSettings().setJavaScriptEnabled(true);
newsdetail.loadUrl(getIntent().getStringExtra("newsdetail"));
}
}
I want to show my externalurl link coming from api in webview in my application.
When I click for detail, it opens on google chrome. but I want it to show in application.
set setWebViewClient in your WebView also you can enable javaScript
webView.loadUrl(getIntent().getStringExtra(LINK));
webView.setWebViewClient(new MyWebViewClient());
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
and Clint is:
private class MyWebViewClient extends WebViewClient {
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
}
I have problem.
I do a progressbar in main2activity.
App starts but when the website its loaded the progressbar is not disappear.
And my app crashed.

Pass progressBar to your custom webview :
myWebView.setWebViewClient(new myWebClient(progressBar));
Change your myWebClient class to this:
public class myWebClient extends WebViewClient {
private ProgressBar progressBar;
public myWebClient(ProgressBar progressBar) {
this.progressBar=progressBar;
progressBar.setVisibility(View.VISIBLE);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
Hope this helps.
Well, you got an null pointer Exception with the progressbar, i would encapsulate every access to the progressbar in this form:
if(progressBar == null)
progressBar = (ProgressBar) findViewById(R.id.progressBar7);
if(progressBar)
progressBar.setVisibility(View.GONE);
Implemented in vour code:
public class Main2Activity extends Activity {
/** Called when the activity is first created. */
WebView myWebView;
ProgressBar progressBar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
myWebView = (WebView) findViewById(R.id.webView);
progressBar = (ProgressBar) findViewById(R.id.progressBar7);
myWebView.setWebViewClient(new myWebClient(this));

The progress bar and webview works fine but when the page is finished loading the progress bar still remains? When I have loaded the page the progress bar visibility doesn't dissapear/change to GONE? Where is the error?
Ive tried both progressBar.setVisibility(View.INVISIBLE) and progressBar.setVisibility(View.GONE); but nothin seems to work.
Instead of using customizing webclient. you use default webclient. your problem is replace this.
view.setWebViewClient(new WebViewClient());
add this
view.setWebViewClient(new MyAppWebViewClient());
and also
progressBar.setVisibility(View.INVISIBLE);
not
view.findViewById(R.id.progressBar1).setVisibility(View.GONE);

just changed WebViewClient to MyWebViewClient, progressBar to progressBar1 & ActionBarActivity to AppCompatActivity and every code seems to work :) thank again every1.. :) #Devendra & #akhil :)

After intent of webview url you have to write progressbar.visibility="View.GONE"
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progressBar.setVisibility(View.GONE);
FGallery.this.progressBar.setProgress(100);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressBar.setVisibility(View.VISIBLE);
FGallery.this.progressBar.setProgress(0);
super.onPageStarted(view, url, favicon);
}
}
This is working for me. you can set it as WebViewClient.
I have a web application that works well but I cannot get the back button to function in the web view. Please see code:
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.view.KeyEvent;
public class extends Activity
{
final Activity activity = this;
WebView WebView;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setUseWideViewPort(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
webView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://www.example.com");
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (WebView != null && (keyCode == KeyEvent.KEYCODE_BACK) && WebView.canGoBack()) {
WebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
The application runs but when the back button is pressed it still exits the application. I am also wanting to add the ability to use a html mailto tag with the application. Any help would be appreciated. Thank you.
Edit:
Include a null check to see if WebView is null before invoking methods on it.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (WebView != null && (keyCode == KeyEvent.KEYCODE_BACK) && WebView.canGoBack()) {
WebView.goBack();
return true;
}
Your code seems correct to me. What is the exact behavior you are hoping to achieve from the back button?
What currently happens when you run the application and press the back button?
Edit, Oh I see what is happening.
You are trying to override onKeyDown() inside your onCreate(). onKeyDown() and onCreate() are both methods of Activity, thus you cannot declare one inside the other.
Try your code like this:
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.view.KeyEvent;
public class DealJargon extends Activity {
final Activity activity = this;
WebView WebView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setUseWideViewPort(true);
webView.loadUrl("http://www.example.com");
}
WebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress){
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
WebView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl){
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
}
});
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && WebView.canGoBack()) {
WebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
Edit 2: Anytime you get some kind of compile error that has something to do with a brace it is likely that you are trying to declare a method inside the declaration of another method. Or something similar.
