The only odd thing I noticed was when using the browser mode. Once the app was pushed into the background, it looked like the server stopped responding. It might be related to foreground service behavior or Android background process limitations, but that's just a guess at this point.
Overall, I think this is a great idea and the implementation is impressive. Nice work.
By the way, this was the error i saw during page navigation, homepage loaded fine. On webview, I didn't see any issue.
