Open new tabs on default browser when using webview

I want to tell you I never try android development before, and this is the first time I'm doing an android app I build a website using ASP.NET and I want to run that site within the android app web view.
So followed a few tutorials and I did so far.
Here when I redirect to some external sites In my site, I open them on another new tab on the browser, here I want to open it on the mobile phone's default browser instead of the opening inside the web view.
need a help to doing that.
This is my app MainActivity code.
public class MainActivity extends AppCompatActivity {
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView=findViewById(R.id.webview);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("http://www.mycustom:5500/test/");
WebSettings websettings = webView.getSettings();
websettings.setJavaScriptEnabled(true);
}
private class MyWebView extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
return super.shouldOverrideUrlLoading(view, request);
}
}
#Override
public void onBackPressed() {
if (webView.isFocused() && webView.canGoBack()){
webView.goBack();
}else{
super.onBackPressed();
}
}
}

How can i add a horizontal progress bar on top of web-view?

I am trying to implement a progress bar at the top of my web-view while the page loads. Just like chrome.
How can i do this?
i have a swipe refresh view in a container.
I've looked at a lot of answers here and tried to implement them, but had no luck.
I just want to implement a simple progress bar (like chrome) every time the web-view loads.
public class MainActivity extends Activity {
WebView browser;
SwipeRefreshLayout mySwipeRefreshLayout;
private ViewTreeObserver.OnScrollChangedListener mOnScrollChangedListener;
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// find the WebView by name in the main.xml of step 2
browser=(WebView)findViewById(R.id.webview);
// Enable javascript
browser.getSettings().setJavaScriptEnabled(true);
// Set WebView client
browser.setWebChromeClient(new WebChromeClient());
browser.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// open in Webview
if (url.contains("example.com") ){
// Can be clever about it like so where myshost is defined in your strings file
// if (Uri.parse(url).getHost().equals(getString(R.string.myhost)))
return false;
}
// open rest of URLS in default browser
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
public void onPageFinished(WebView view, String url) {
mySwipeRefreshLayout.setRefreshing(false);
}
});
// Load the webpage
browser.loadUrl("https://example.com/");
mySwipeRefreshLayout = this.findViewById(R.id.swipeContainer);
mySwipeRefreshLayout.setOnRefreshListener(
new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
browser.reload();
}
}
);
}

Can't play this video error in android WebView using RTSP stream

My App has a WebView which loads a simple html. However, this html links to a rtsp live video stream and the WebView is able to load it, but when I click on one video it shows as loading the player but after some time getting message "Can't play this video.. When I open the rtsp link in the native Android browser, it loads and works fine so I know it's not the video stream being incompatible. Is there something within WebView which can be enabled to allow the rtsp video stream to be played? I tried this in both emulator and original device.
Thanks!
public class MainActivity extends Activity
{
private Button button;
public void onCreate(Bundle savedInstanceState)
{
final Context context = this;
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button) findViewById(R.id.buttonUrl);
button.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View arg0)
{
Intent intent = new Intent(context, WebViewActivity.class);
startActivity(intent);
}
});
}
}
public class WebViewActivity extends Activity
{
private WebView webView;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://myurl.com/");
}
}

I was able to redirect the stream to a video player using:
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("rtsp")) {
Uri uri = Uri.parse(url);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
return true;
}
return super.shouldOverrideUrlLoading(view, url);
}
});
