With the simple below code I can get my url loaded correctly, but, I get \"ERR_UNKNOWN_URL_SCHEME\" when trying to tap on html links that starts with mailto: wh
This Work For Me
"webview.setWebViewClient(new WebViewClient() { String currentUrl;
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
currentUrl = url;
if (url.startsWith("http") || url.startsWith("https")) {
return false;
}
if (url.startsWith("intent")) {
try {
Intent intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);
String fallbackUrl = intent.getStringExtra("browser_fallback_url");
if (fallbackUrl != null) {
webview.loadUrl(fallbackUrl);
return true;
}}
catch (URISyntaxException e) {
//not an intent uri
}
return true;//do nothing in other cases
mailto
links will not get loaded in your webview
.You have check for it like this in shouldOverrideUrlLoading
and handle it with intent
.
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.startsWith("mailto:")) {
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));
view.reload();
return true;
}
}

@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;
}
Put this code in your mWebView.setWebViewClient(new WebViewClient(). it will be working perfectly for all link like tel:, whatsapp:, mailto: etc.
You have to set a client in the webview and pass these to an intent
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if( URLUtil.isNetworkUrl(url) ) {
return false;
}
if (appInstalledOrNot(url)) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity( intent );
} else {
// do something if app is not installed
}
return true;
}
});
}
You can have a method to check if app is installed
private boolean appInstalledOrNot(String uri) {
PackageManager pm = getPackageManager();
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException e) {
}
return false;
}
You need override the method shouldOverrideUrlLoading
of WebViewClient in which you can control link transfer by yourself.
Because html links that starts with mailto: whatsapp: and tg: (Telegram).
is not common url start with "http://" or "https://", so WebView cannot parse it to right place, we should use intent to redirect the url.
For example:
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url == null || url.startsWith("http://") || url.startsWith("https://")) return false;
try {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
} catch (Exception e) {
Log.i(TAG, "shouldOverrideUrlLoading Exception:" + e);
return true;
}
}
then setWebViewClient to your WebView, like this:
public class MainActivity extends Activity {
private WebView mWebView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url == null || url.startsWith("http://") || url.startsWith("https://")) return false;
try {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
} catch (Exception e) {
Log.i(TAG, "shouldOverrideUrlLoading Exception:" + e);
return true;
}
}
});
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
// Use remote resource
mWebView.loadUrl("http://myexample.com");
}}
