I've got a Lenovo TAB A7-10 android tables
When i connect my camera nikon d5200, software is qDslrDashboard V0.3.4.3 the lenove is saying: host is missing.
Anyone know a sollution for this problem?

There are at least 2 versions of A7-10.
And from what you have wrote it looks that your tablet doesn't have usb-host functionality.
You can simply check it using app "USB Device Info" - install it, connect camera to tablet (of course using USB-OTG adapter), run app and check both tabs (linux and android) - your camera should be visible and identified in both. If not - your tablet doesn't have usb-host needed to work with qDD.
