Android camera crash, repeating images, native nav buttons messed up

Question

I have a bar-code scanning Cordova (webview) app, and after a certain point, if I restart the barcode-scanning camera, I get a crazy crash that bricks my phone until I give the entire phone a full restart:

Stats:

Nexus 5 Android 4.4.4 Kernel 3.4.0-gd59db4e

I'm using the zbar scanning lib, which uses OpenCV.

Here's the catlog right around the time that things go haywire; once I start getting "Failed to get_buf", the repeating image effect kicks in and I have to restart my phone.

Any ideas?

The answer posted by my colleague at the following link solved our problem:

OK we had the same problem - Nexus 5 only, but with ZBar lib instead of ZXing.

The issue was resolved by switching from a SurfaceView to a TextureView - however this resulted in slower frame rates.

Through testing we found that our issue was caused by leaving the screen, bringing up the keyboard and going back - our solution was setting android:windowSoftInputMode to AdjustPan in the manifest.
