Incompatibility with Android System WebView 49

[Wandrer]

With Android System WebView 49.0.2623.34 present in the Android System, K-9 does not show the content of mails anymore, only a blank page.

I tested this on the Samsung G900F and the Sony SGP612.

Android System WebView 48.0.2564.99 does work fine on both devices.

I'm using K-9 version 5.007.

I had the same problem with K-9 Mail 5.107 and WebView 49.0.2623.34 on an LG G3 with Marshmallow. Uninstalling WebView updates back to 45.0.2454.95 fixed it.

Please make sure to report this issue to Google. The linked bug report is from November 2015 and is not about whatever they changed in WebView 49.0.2623.34.

Can you all please test if 5.008-RC1 fixes this issue for you?

Both reverting Webview to 48., and better, using k9 5.008-RC1, restored the message bodies, thanks. To clarified, I reverted Webview and that worked, and then I let play store update Webview to 49. and then updated to the new k9 and it still worked.

Works but Avast reports a cloud virus. I already reported back as a false alert.

It works for me too.
