Background: We are migrating our CC 2.1 project to CC3.3 and we found out that game kept crashing when a certain webview was loaded. After tracing down the errors, it was due to Webview’s onJsCallback.
To replicate, we can simply follow the official guide and the app will crash when JS interface scheme is loaded (eg: testkey://a=1&b=2 ).
Tested with both CC 3.3 and 3.2.
Example Project Attached: WebViewError.zip (31.0 KB)
We would appreciate if you could follow up with this issue ASAP.
Many thanks in advance.
Edit: Issue reported as well:
OK. I can ask engineering to take a look. Thank you for creating the GitHub issue and uploading a demo.
Thanks @slackmoehrle
If they are busy, just guide me which file to fix.
I will be very happy to contribute 
On the other hand, project deadline is due in next 2 weeks. 
Thanks for the feedback, I can reproduce this crash problem on your demo. version 3.3.0
Please try to modify this, and then try to see if it works.
CocosWebView.java line 156
CocosHelper.runOnGameThread(new Runnable() {
@Override
public void run() {
CocosWebViewHelper._didFailLoading(mViewTag, failingUrl);
}
});
Thanks! I will give it a try tonight and will get back to you 
Sorry. I could not fix it 
Might be I was fixing the wrong file?
Is that the right path?
/Applications/CocosCreator/Creator/3.3.0/CocosCreator.app/Contents/Resources/resources/3d/engine-native/cocos/platform/android/java/src/com/cocos/lib
i haved replied in Github.
Did you manage to fix it?
