Display blinks the first time

[FernandoFranco]

Helo, i used the QRCodeReaderView in a Fragment, and MaterialTabs.
It works, but the display blinks in the first time to create this fragment.

Did you test and reproduce it in different devices?

[FernandoFranco]

Yes

I have same issue.
I try to fix this by delay init QRCodeReaderView but when QRCodeReaderView init, the screen still blinked.

This is related to this issue, so I'm merging this with #7
