Apps Problem with android studio (design window and launching on emulator)

[Yoyojava]

Hello,
I am new with Android studios but I all ready use it to do some basic project. I have got a problem with the design window, I can not use it and their is something write in it: "Exception raised during rendering: com/android/util/PropertiesMap".
I have an other problem, when I am launching the app on an emulator, it quite the app imediatly ("Unfortunately, New_app has stopped). I don't know if it's relating but when I create a new project I have got two errors in the AndroidManifest. The first one talke about the Backup for sdk version 23 and up. The other say: "app is not indexable by google search; consider adding at least one Activity with Action-View intent-filler".
Thank you
