Using WebView from more than one process at once

Issue

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

Cause

Typically, occurs when multiple processes within 1 app use web views.

TBLClassicUnit extends WebView, and must be treated as a WebView in this regard.

Resolution

Make sure that your app uses 1 process to manage all web views.

In the words of the WebView JavaDoc:

Most applications should simply ensure that all components of the app that rely on WebView are in the same proces, to avoid needing multiple data directories.

Alternative Resolution

If you are unable to implement the above resolution, then you can try the following:

Make sure that each process in your app calls the WebView.setDataDirectorySuffix(<Process-specific data directory>) method, before creating or using a WebView instance.

TBLClassicUnit extends WebView, and must be treated as a WebView in this regard.
