i already tried for creating Wifi tethering in raspberry PI 3 and found that currently we can not create wifi tethering for internet sharing .You can also look at my raised question at android things forum at issue tracker

You can use startLocalOnlyHotspot introduce in android 7 but it will not share internet , only allow local connection .

NOTE : For android.permission.WRITE_SETTINGS if you set target below android 7 then it will not create exception but still i found that it does not allow any connection to that hotspot.
