I'm trying to open up a Chrome custom tab from within a webview inside of an Android app. In order to do this, I figured I could register a custom URL handler(customtab://www.myurl.com/). The error I'm running into is that chromium(the webview) is blocking the custom URL handler due to an insecure content error (This request has been blocked; the content must be served over HTTPS.). The URL is https. Even adding webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW); on the webView didn't work.
Any ideas on how I can register this custom handler as "secure"?

You can use web intent to open url in chrome
Intent webIntent = new Intent(Intent.ACTION_VIEW);
webIntent.setData(Uri.parse(url));
getActivity().startActivity(webIntent);

You need to override this method on the Webview to skip ssl errors
public synchronized void onReceivedSslError(WebView view, final SslErrorHandler handler,SslError error) { handler.proceed(); } Answers 3
I am open my custom URL in web view in android with follow below process.
Design your webview as full screen like
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:layout_margin="20dp" android:gravity="center" android:background="#ffffff"> <WebView android:id="@+id/WebView" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="10dp"/> </RelativeLayout> And in you .java file add below code in onCreate method
webView = (WebView) findViewById(R.id.WebView); windowwidth = getWindowManager().getDefaultDisplay().getWidth(); windowheight = getWindowManager().getDefaultDisplay().getHeight(); getWindow().setLayout(windowwidth, windowheight); WebSettings settings = webView.getSettings(); settings.setJavaScriptEnabled(true); settings.setAppCacheEnabled(false); settings.setDomStorageEnabled(true); try { // here i call progressdialog which is load still the page is not load //properly Constants.ShowProgressDialog(MyActivity.this, "", "Please wait..."); webView.setWebViewClient(new WebViewClient() { public boolean shouldOverrideUrlLoading(WebView view, String url) { Log.i("", "Processing webview url click..."); view.loadUrl(url); return true; } public void onPageFinished(WebView view, String url) { Log.i("", "Finished loading URL: " + url); // dismiss the progressbar after load the web page in webview. Constants.disMisProgressdialog(); } @Override public void onLoadResource(WebView view, String url) { super.onLoadResource(view, url); } }); webView.loadUrl("<your url>"); } catch (Exception e) { e.printStackTrace(); } If still any issue please provide me your url I'll check and provide you the code.
Hope your problme resolve.
Make sure provide permission in Manifest file.

You simply need to register a WebViewClient in your WebView and override the shouldOverrideUrlLoading() method to support your own scheme:
public boolean shouldOverrideUrlLoading(WebView view, String url) { if (url.startsWith("custometab://")) { // TODO: start custom tabs for the url. return true; } else { return false; } } (see http://stackoverflow.com/a/5514668/94363)
The problem is: how do you know when clicking on customtab://www.myurl.example.com/ if you should open http://www.myurl.example.com or https://www.myurl.example.com?
- You could either introduce
customtab://andcustomtabs:// - or do some manipulation of the URL
customtab://http/www.myurl.example.com
But in fact, I don't think we need a custom scheme at all if you want to open all links with custom tabs. Just use:
public boolean shouldOverrideUrlLoading(WebView view, String url) { // TODO: start custom tabs for the url return true; }
