** Description
Will you stop supporting Android 5? At least the arm-v7 version should have it. Since the reason we use newpipe is to avoid having to use web pages or apps that are too heavy for old smartphones.
I'm very interested in this fork to see "Age restricted content"
and also see niconico videos

MinSdk will be back to 21 since 4.2.0.
