• How to make android app using WebView without lags?

  I'm just trying to build my first app using WebView for website wikidiy.org. I've tried a lot approaches I found here, but the app is still very laggy. Is there any way how to make this app without laggs? When I open website in Chrome browser, it is smooth and correctly running, but in WebView app it is almost impossible tu use.
  

  Edit: Is it make sense to do it with webview? Or I should learn how to do it with WP RestAPI as a native app?

• ubilinux Debian serial port out of order

  I have 6 USB ports connected to ubilinux upboard via a 7 port serial hub. ebay usb hub. Using python 27, pyserial.

  When ubilinux boots, it usually locates the ports in a particular order: USB0 through USB5. Occasionally, when booting, it will find them in a different order, skipping some, and adding them with higher number, i.e. USB7. Sometimes they are simply out of order. Although, easy to detect, now I am forced to reboot, not desirable. Is there a way to command Linux to re-attach them, or can I hardwire them somehow?
