Some way to make the status bar transparent

Hello everyone from the community. I’m wanting to make the status bar transparent. Below I leave the topics that probe, but unfortunately it has not worked for me.

The cause:

The truth is that I would like to be able to fix the issue of making the status bar transparent, since the effect it produces is too much in terms of interface, design, etc. and it is spectacular.

Sorry for the English, if something is not understood is because I am translating with the Google Translator, and may end up having some errors. :grinning:

Thank you! DTA
