…ception Summary: We are seeing crash reports that the webview is missing. In this case it should fail gracefully so that a missing webview does not block from using an app built with React Native. The contains could also be changed to check for "webview" in general to catch all webview related exception. It's currenlty checking on for the specific string that I'm seeing in our app's crashreporting tool.

…6189) Summary: We have been experiencing the below crashes in our Flipkart Android app:   Stack overflow thread for the issue that is causing this crash: [https://stackoverflow.com/a/56246743](https://stackoverflow.com/a/56246743) The change I have done is an enhancement on the following PR which got merged to master: [https://github.com/facebook/react-native/pull/24533](https://github.com/facebook/react-native/pull/24533) The exception handling for this crash already exists but it relies on having a specific string in the error message ("Webview not installed"). But the error message for the crashes above does not include this string. I have added a check for all the crashes involving the `MissingWebViewPackageException`. Refer the file: [https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/webkit/WebViewFactory.java#102](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/webkit/WebViewFactory.java#102) ## Changelog [ANDROID] [Fixed] - The ReactCookieJarContainer/ForwardingCookieHandler now handles all the cases of missing WebView exceptions gracefully. Pull Request resolved: #26189 Test Plan: No new tests have been added. CI should pass. This fix was made based on the exception stacktrace. I have not spent the time to acquire one of the devices that it is happening on. Differential Revision: D17258881 Pulled By: cpojer fbshipit-source-id: 3abb061e345329214025ebab2b3a908f9cce434d

Summary: I applied the changes requested in this PR: #29089 We upgraded to RN 0.62.2 on our latest release and started to see again the "Failed to load WebView provider: No WebView installed" (see below for Crashlytics screenshot)  This crash had been fixed by #24533 but #26189 (added in 0.62) reverted the fix Indeed the exception raised in Crashlytics is actually a `AndroidRuntimeException` and `MissingWebViewPackageException` is only part of the message. For instance, in the screenshot above, the exception message is `android.webkit.WebViewFactory$MissingWebViewPackageException: Failed to load WebView provider: No WebView installed` Now these crashes are quite tricky to reproduce, so to be on the safe side, I'm filtering out all exceptions containing `WebView` as suggested by thorbenprimke on the original fix. If my reasoning is correct, it should fix siddhantsoni 's issue as well, since `WebView` is included in `MissingWebViewPackageException` But following that reasoning, I am not sure #26189 fixed siddhantsoni 's issue, so siddhantsoni if you could check that this PR also fixes your issue, that would be great! ## Changelog [Android] [Fixed] - Fix missing WebView provider crash in ForwardingCookieHandler <!-- Help reviewers and the release process by writing your own changelog entry. For an example, see: https://github.com/facebook/react-native/wiki/Changelog --> Pull Request resolved: #32165 Test Plan: I created a version of react native with this patch applied ``` "react-native": "almouro/react-native#release/062-2-fix-missing-webview-provider" ``` Before the fix ~0.1% of our users were impacted on Android, no new crashes have occurred after the update. This is putting back what was already in place and working for us, but making the check wider to catch more errors.
