[GitHub] [cordova-android] zhqcqupt opened a new issue #1000: exception throwed when cordovaActivity destroy
zhqcqupt opened a new issue #1000:
URL: https://github.com/apache/cordova-android/issues/1000
# Bug Report
## Problem
In Android,we use cordova to load url ,but when activity.finish() is called ,a exception throws ,that is
Application attempted to call on a destroyed WebView java.lang.Throwable.
According to my analysis, this exception affected some behavior of my next activity, such as calling activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE);
I found the cordova code where the exception was thrown (CordovaWebviewImpl#handleDestroy) and commented out the code that caused the exception (this.loadUrl("about:blank");). There will be no above problems, and my setFlags function normally
### What is expected to happen?
with no exception throws when CordovaActivity destroy
### What does actually happen?
see above

Wonder if that TODO applies here... :thinking: Perhaps it's a race condition.

In a case like that I would strongly recommend the following ideas:
- Try upgrading as much as you can, one thing at a time, and see what happens.
- Get rid of all generated artifacts such as node_modules, plugins, and platforms, migrate configuration of plugins and platforms from config.xml to package.json, and try building.
- Try creating a new project then try implementing one thing at a time to see what does and does not work.
In short, try one thing at a time to make a [minimal, reproducible example](https://stackoverflow.com/help/minimal-reproducible-example).

It's a bit embarrassing. Under the latest Cordova project(a demo), I destroy the Cordova page and still report that exception. However, I found that my previous inference was not true, that is, Cordova's closing affected the setflag setting of the next page.
cordova -v 9.0.0 (cordova-lib@9.0.1)，Installed platforms: android 8.1.0
the excption stacktrace is different than before

Sorry, our project is relatively old, and it has been handed over many times by many people. At present, we only have the source code of the cordova framework and various plugins, and there is no complete Cordova environment and configuration. What is certain is that the PLATFORM_VERSION_BUILD_LABEL in cordova.js we use is 5.1.1, which corresponds to Installed platforms. Other information is unclear. (The version information of the camera plug-in is "cordova-plugin-camera 4.1.0 "Camera"". Although this information should be useless, it is still provided to you). I also read the relevant information before asking the question, I am not sure that the new version fixes the problem. Thank you.

Can confirm that. cordova-android 9.0.0 with android 9.0.0, targetSdk set to 29 or 30 (reproduced on both), but bug is there on all devices starting with API 24+ (didn't test for lower)
Commenting out the line that @zhqcqupt mentioned makes that exception disappear.
I there a less hacky way though to bypass it?

I'd also like to add that cordova-android 5.1.1 is extremely dated and will likely not work with modern sdk versions. It certainly wouldn't pass Google's Play expectations.
