How to make a webview launch another app in android app

I am trying to mirror a website in an android app which I already got a way around it, but am having issues with sharing information inside the app to social media, like when it is clicked in the app to share information to WhatsApp, Facebook, etc I want the app to be able to find each app and open the app with the information, I've tried all way but it's not working kindly help if you can
Thanks in advance
my code
public class MainActivity extends AppCompatActivity {
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.loadUrl("https://eliteglobalnetwork.net/");
webView.setWebViewClient(new WebViewClient());
}
#Override
public void onBackPressed() {
if (webView.canGoBack()){
webView.goBack();
}else {
super.onBackPressed();
}
}
}

public static final String WEBSITE_ADDRESS = "website_address";
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String url = getIntent().getStringExtra(WEBSITE_ADDRESS);
if (url == null || url.isEmpty()) finish();
setContentView(R.layout.activity_webview); //name of your layout
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl(url);
}
If want to open in same app -
Intent i = new Intent(YourActivity.this, WebViewActivity.class);
i.putExtra(WebViewActivity.WEBSITE_ADDRESS, ""http://www.google.com"");
startActivity(i);
Add it in Manifest file -
<uses-permission android:name="android.permission.INTERNET" />

WebViewClient shouldOverrideUrlLoading doesn't seem to work

I'm trying to listen to url changes from a WebView client and just log the updates. I'm navigating through my webView and shouldOverrideUrlLoading() is never called. I don't know why.
Here is my code :
public class WebViewActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
Intent i = getIntent();
String url= i.getStringExtra("url");
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
String currentUrl = url;
Log.i("currentUrl",": " + currentUrl);
view.loadUrl(url);
return true;
}
});
webView.loadUrl(url);
}
}

Whatsapp Api not getting loaded in webview android

I am able to load the website properly in the app but it has a function which redirects users to whatsapp. The api works fine on mobile browser and on PC/laptop. But in the android app it loads for a second and then says webpage unavailable. What am I missing?
Image 1 stays only for a second.
After 1 second loading time :
Main Java Code:
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.loadUrl("https://zzzz/");
WebSettings webSettings=mywebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mywebView.setWebViewClient(new WebViewClient());
}
#Override
public void onBackPressed(){
if(mywebView.canGoBack()) {
mywebView.goBack();
}
else{
super.onBackPressed();
}
}
}

Override this shouldOverrideUrlLoading and do this in it
Code
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView wv, String url) {
if(url.startsWith("tel:") || url.startsWith("whatsapp:")) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
return false;
}
});
Your code should be like this
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.loadUrl("https://naturesexpress.in/");
WebSettings webSettings=mywebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView wv, String url) {
if(url.startsWith("tel:") || url.startsWith("whatsapp:")) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
return false;
}
});
}

How to open a url other than defined url in webview?

I tried my best but it doesn't work for me. I want to open url other than http://google.com in default browser. What code should add inside, I seen android documentation and added the code but it doesn't work. Any suggestion is appreciated.
public class MainActivity extends Activity {
private WebView webview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
this.webview = (WebView) findViewById(R.id.activity_main_webview);
webview.loadUrl("http://google.com");
WebSettings settings = webview.getSettings();
settings.setJavaScriptEnabled(true);
webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webview.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
}
}

You can try to this hope this can help you..
public class MainActivity extends AppCompatActivity {
private TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.tv);
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Uri uri = Uri.parse("http://gmail.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
}
});
}
}

try this snippet and make sure you have Internet permission in manifest file
public class MainActivity extends Activity {
private WebView webview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview = (WebView) findViewById(R.id.activity_main_webview);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
webview.loadUrl("http://google.com/");
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
String myAlternativeURL = "http://yahoo.com";
if (!url.equals(myAlternativeURL)) {
view.loadUrl(myAlternativeURL);
return true;
}
}
});
});

Android Webview shows error in emulator

i have a problem with loading a webview from a string url.
here is the code of an activity with only WebView.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web);
Intent intent=getIntent();
String url=intent.getStringExtra("url");
//EditText edit=(EditText)findViewById(R.id.editText1);
//String url=edit.getText().toString();
WebView webview=(WebView)findViewById(R.id.webView1);
webview.loadUrl(url);
webview.setWebViewClient(new WebViewClient());
}`
and code of the calling activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onGo(View v)
{
EditText edit=(EditText)findViewById(R.id.editText1);
Intent intent=new Intent(MainActivity.this,WebActivity.class);
intent.putExtra("url", edit.getText().toString());
startActivity(intent);
}
i have even added the android.permissions.INTERNET in the manifest
but still i cannot view the page with the click of the button in MainActivity.

From the comment
yes the real device has the same error with "www.google.com"
Use
http://www.google.com
Also make sure you have internet permission mentioned in manifest file

private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
