Android- mailto link won't work

Question

I have read many Questions about this topic here at stackoverflow, also my solution come from here but it won't work. Also there is no error message.

I have a webview in Android and a Homepage, there are some mailto links, when I try to open the mailto links from my webview in a mailclient, the webview always open the mail address like a normal webpage.

Could someone look at my code and tell my what's wrong?

Thank's for your help.

EDIT:

If I try this I get the error message "The method replaseFirst(String) is undefined for the type String". In cause of this I changed url.replaseFirst to url.replaceFirst but his needs a secound argument so I have to write url.replaceFirst("mailto:", X );. For X I can type mail,url or null. I tryed everyone, by each I get the message that I have to add a return statement, so I did it with return false. Now I have this code:

public class MyWebViewClient extends WebViewClient {
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                if(url.startsWith("mailto:")) {
                      String mail = url.replaceFirst ("mailto:", mail);
                      Intent intent = new Intent(Intent.ACTION_SEND);
                      intent.setType("message/rfc822");
                      intent.putExtra(Intent.EXTRA_EMAIL, mail );


                      startActivity(Intent.createChooser(intent, "Send Email"));
             }
                return false;
        }
    }

This does not work. So I try intent.setType("message/rfc822"); instead of intent.setType("text/plain"); but this also does not work.

What I have done wrong?

EDIT2:

new code:

public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if(url.startsWith("mailto:")) {
                String mail = url.replaceFirst("mailto:", "");
                Intent intent = new Intent(Intent.ACTION_SEND);
                intent.setType("text/plain");
                intent.putExtra(Intent.EXTRA_EMAIL, mail );

                startActivity(Intent.createChooser(intent, "Send Email"));
             }  
            else if(url.startsWith("http:") || url.startsWith("https:")) {
                    view.loadUrl(url);
                }
                return true;
        }

Solution 1

To force the open of mail client you can try that:

if(url.startsWith("mailto:")) {
  String mail = url.replaceFirst("mailto:", "");
  Intent intent = new Intent(Intent.ACTION_SEND);
  intent.setType("text/plain");
  intent.putExtra(Intent.EXTRA_EMAIL, mail );
  // intent.putExtra(Intent.EXTRA_SUBJECT, "Subject"); // if you want extra
  // intent.putExtra(Intent.EXTRA_TEXT, "I'm email body."); // if you want extra

  startActivity(Intent.createChooser(intent, "Send Email"));
} else if ... {
   // your code as is
}

but other "send" apps open too, depends of support of Intent.ACTION_SEND

Instead of intent.setType("text/plain"); here is suggested the use of intent.setType("message/rfc822"); but I have never tested.

Edit:

change lines of main.java:

// ...
WebView myWebView = (WebView) findViewById (R.id.webView1);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new MyWebViewClient()); // you name your class MyWebViewClient not WebViewClient
myWebView.loadUrl("WEBSITE"); // also change line order
// ...

Solution 2

My example:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL,  new String[]{"THE_EMAIL_ADDRESS_WITHOUT_mailto:"});
startActivity(Intent.createChooser(intent, "Send Email"));

Notice the string array. If you pass only a string it will not be considered.

Solution 3

Although this is an old question I found none of the answers above worked 100% for me. I want to only open email apps, not text message etc.

I used this code instead, (with no intent.SetType)

String[] email_address = new String[] {getString(R.string.email_address)};
Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto", getString(R.string.email_address), null));
intent.putExtra(Intent.EXTRA_EMAIL, email_address);
intent.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.email_subject_question));
startActivity(Intent.createChooser(intent, "Send Email"));

The extra line: intent.putExtra(Intent.EXTRA_EMAIL, email_address); is so it works on all versions of android.
