Is shouldOverrideUrlLoading really deprecated What can I use instead

Question

Is  shouldOverrideUrlLoading  really deprecated  If so  what can I use instead   It seems like shouldOverrideUrlLoading is deprecated targeting Android N and I need to make an app work since API 19 until the latest right now which is Android N  beta   I use some features that are new in Android N  like Data Saver   so targeting Marshmallow will not help with the issue since I need to use those new features  here is the part of the code I use   public boolean shouldOverrideUrlLoading WebView webview  String url        if  url startsWith  http       url startsWith  https                         else if  url startsWith  sms                                     And this is the message Android Studio gave me      Overrides deprecated method in  android webkit WebViewClient        This inspection reports where deprecated code is used in the specified inspection scope    Google says nothing about that deprecation   I wonder if using  SuppressWarnings  deprecation   will let me work on all devices since the API 19 until the latest Android N Beta  and its final version when it gets released   I can t test it myself  I never used that and I need to be sure that it works  so  anyone can tell

The version I m using I think is the good one  since is the exact same as the Android Developer Docs  except for the name of the string  they used  view  and I used  webview   for the rest is the same   No  it is not   The one that is new to the N Developer Preview has this method signature   public boolean shouldOverrideUrlLoading WebView view  WebResourceRequest request    The one that is supported by all Android versions  including N  has this method signature   public boolean shouldOverrideUrlLoading WebView view  String url       So why should I do to make it work on all versions    Override the deprecated one  the one that takes a String as the second parameter

Documenting in detail for future readers   The short answer is you need to override both the methods  The shouldOverrideUrlLoading WebView view  String url  method is deprecated in API 24 and the shouldOverrideUrlLoading WebView view  WebResourceRequest request  method is added in API 24  If you are targeting older versions of android  you need the former method  and if you are targeting 24  or later  if someone is reading this in distant future  it s advisable to override the latter method as well   The below is the skeleton on how you would accomplish this   class CustomWebViewClient extends WebViewClient         SuppressWarnings  deprecation        Override     public boolean shouldOverrideUrlLoading WebView view  String url            final Uri uri   Uri parse url           return handleUri uri               TargetApi Build VERSION CODES N       Override     public boolean shouldOverrideUrlLoading WebView view  WebResourceRequest request            final Uri uri   request getUrl            return handleUri uri              private boolean handleUri final Uri uri            Log i TAG   Uri      uri           final String host   uri getHost            final String scheme   uri getScheme               Based on some condition you need to determine if you are going to load the url             in your web view itself or in a browser              You can use  host  or  scheme  or any part of the  uri  to decide          if     any condition                      Returning false means that you are going to load this url in the webView itself             return false            else                  Returning true means that you need to handle what to do with the url                e g  open web page in a Browser             final Intent intent   new Intent Intent ACTION VIEW  uri               startActivity intent               return true                      Just like shouldOverrideUrlLoading  you can come up with a similar approach for shouldInterceptRequest method
