NOTE: This comment is auto-generated.

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

It should be impossible that when creating an instance of the ChromeSafariBrowser, the java.lang.NullPointerException: Attempt to read from field 'com.pichillilorenzo.flutter_inappwebview.InAppWebViewFlutterPlugin com.pichillilorenzo.flutter_inappwebview.chrome_custom_tabs.ChromeSafariBrowserManager.plugin' on a null object reference could happen. It doesn't make any sense to me, as a ChromeSafariBrowserManager native class is always instantiated before starting a new ChromeCustomTabsActivity, otherwise, it couldn't do that. Could you post the code you are using about the ChromeSafariBrowser class? How are you using it? Where do you call it? Thanks

I'm using InAppWebView as a widget, and then in shouldOverrideUrlLoading method, depending on which url I get, I open the browser.

               child: 
                     InAppWebView(

                          initialUrlRequest: URLRequest(
                              url: Uri.parse(UrlConstants.liveTickerUrl)),

                          initialOptions: InAppWebViewGroupOptions(
                              android: AndroidInAppWebViewOptions(
                                  verticalScrollbarPosition:
                                      AndroidVerticalScrollbarPosition
                                          .SCROLLBAR_POSITION_RIGHT),
                              crossPlatform: InAppWebViewOptions(
                                supportZoom: false,
                                useShouldOverrideUrlLoading: true,
                              )),

                          onWebViewCreated: (controller) {
                            webView = controller;
                            // Hide Progress Indicator
                            loadingIndicatorVisible.value = false;
                          },

                          shouldOverrideUrlLoading:
                              (controller, navigationActionPolicy) async {
                            var url = navigationActionPolicy.request.url!;

                                .contains(UrlConstants.aditionUrl.trim())) {
                              chromeSafariBrowser.open(url: url);

Can you please give me more information on how to reproduce the bug. Thanks!

MathieuBa commented 3 years ago

Alright, I tried to reproduce it with the minimum application possible and succeed, but it's a problem really specific, don't know if you want to pass a lot of time on it and don't know if you will be able to reproduce. I will explain.

I used your example on ChromeSafariBrowser and get it working with https://flutter.dev/

Then, I used a local url (I can't give it to you, sorry) totally blocked behind an htaccess. Still working.

Where the crash come is when the url (still a local one) is allowed by the htaccess, but other data (css, js, ...) are all blocked.

I tried it on two differents configurations:

For now, that's all the information that I can give you. But don't hesitate to ask more :)

frankteller-de commented 3 years ago

The app crashes if chrome is not installed on the device. That happens on Samsung devices. #1009

JasonSheedy commented 2 years ago

I'm seeing the same issue reported in crashlytics on a variety of devices. Has there been any progress identifying the root cause @pichillilorenzo Looking at the source for ChromeCustomTabsActivity I can see there's a lot of potential for this to be returned as null. I'm not sure how this is set in the Bundle, but it seems if the managerId is not set this will result in an NPE. 

    Bundle b = getIntent().getExtras();
    assert b != null;
    id = b.getString("id");

    String managerId = b.getString("managerId");
    manager = (ChromeSafariBrowserManager) ChromeSafariBrowserManager.shared.get(managerId);
diegoalex commented 2 years ago

same error here on a variety of android devices. I've put a lot of logs to send to crashlytics and I got none of them. And then I realized that it's happing when the app is launching. And I just started ta have this error more frequently last couple of weeks.

andredealmei commented 2 years ago

is there any workaround for this ?

pichillilorenzo commented 2 years ago

Have you tried the latest version of the plugin? There shouldn't be that error anymore

sarunyool commented 2 years ago

@diegoalex Hello, I would like to follow up your issue. We have been getting the same logs as you recently. Have you updated to the latest version? Do you still get the same crash log?

Thank you in advance.
