"mailto:" and "tel://" can't work in a WebView app, the webpage is hosted by UNAS

I saw so many similar questions, but none of them can helped me.
Here's the part of the mailto and tel handle:
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
String url_https = "https://somivill-flex.hu/";
String url_http = "http://somivill-flex.hu/";
if (url != null && (url.startsWith("http://") || url.startsWith("https://"))) {
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
}
else if (url.startsWith("mailto:")) {
String mail_add = url.replace("mailto:", "");
MailTo mailto = MailTo.parse(mail_add);
Intent mail = new Intent(Intent.ACTION_SEND);
mail.setType("message/rfc822");
mail.putExtra(Intent.EXTRA_SUBJECT, "Kérdés");
mail.putExtra(Intent.EXTRA_EMAIL, new String[]{mailto.getTo()});
startActivity(mail);
return false;
}
else if (url.startsWith("tel://")) {
String dial_num = url.replace("tel://", "");
Intent dial = new Intent(Intent.ACTION_DIAL, Uri.parse(dial_num));
startActivity(dial);
return true;
}
return true;
}
}
Here's the AndroidManifest.xml file permission part:
?xml version="1.0" encoding="utf-8"?>

My problema is that, if I click on one of the 2 links above, the app still stays in the WebView, and says that UNKNOWN_URL_SCHEME. My other idea is to let these two link formats out of the WebView and let open it in browser but I'm not professional in java.
I hope someone can help me. If you can, thanks a lot!
Have a nice day guys!

I am working on OCR reader application. below is my java code. My question is how to start another method if one is completed?

When the user captures the image, the device will automatically read aloud the text. for that i have implemented texttospeech method but when this activity stop i want to start another task. how will it can be done?
After reading the captured text, I want to implement another text-to-speech method how can i do this?

just use the same mode on text to speech ADD and it will play when the first one is done, ADD = ADD, FLUSH = reset
textToSpeech.speak("this will play when first is done",

You have to call startVoiceInput() again.
You are setting this call for an onClick() handler on a TextView already.

launch another application from my own app

So I'm writing a voice assistant app for my final in Intro to Android, and I got most of it to work however I would like the intent for Instagram to open the app not the website. (That would be good enough for now)
I have tried several solutions from here to no avail.
Ideally, I would like for it to get a list of installed apps and throw those in an array that just responds to the apps name
I have the code is as follows, written in Java.
Any help will be appreciated.

remove all the intents from your code except the one from this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
final Uri uri = Uri.parse(data.getStringExtra("KEY_URI"));
new Thread(new Runnable() {
#Override
public void run() {
String verifier = uri.getQueryParameter(LoginActivity.URL_TWITTER_OAUTH_VERIFIER);
try {
AccessToken accessToken = twitter.getOAuthAccessToken(requestToken, verifier);
LoginActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(LoginActivity.this, CategoriesActivity.class);
startActivity(intent);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
Just keep the intent portion in order to go to the next activity in OnActivityResult itself, remove any other intent calls from your entire code and try running the app again.
