java.lang.RuntimeException: Using WebView from more than one process at once

[ryandt]

Hey there. My app's bug reporting tool is reporting several crashes around the use of WebView in LocalizationApplicationDelegate.

Unable to create application [application.name]: java.lang.RuntimeException: Using WebView from more than one process at once with the same data directory is not supported. https://crbug.com/558377 : Current process [process name] (pid 20098), lock owner [process name] (pid 21177)

I'm unfortunately not sure how to reproduce this crash. My best guess is that my application is trying to instantiate a WebView on startup with the same process name as another instance of my app that is in the process of getting killed.

I see that the WebView is used in LocalizationApplicationDelegate like this

class LocalizationApplicationDelegate {
    fun onCreate(context: Context) {
        WebView(context).destroy()
    }
    ...
}

An WebView object is created and immediately destroyed created and immediately destroyed. I am sure this is the reason of your problem.

For what a WebView is required to handle localization issues?

@oschildt That's right. This was most likely added to address this issue. But unfortunately this workaround introduces an issue of its own with multiple processes being active at once.
